This issue of AirMail highlights research and

development – one of the most valuable

resources and strengths of the Camfil Farr

Group.

R&D plays an important role in our innova-

tion process and R&D – like innovation – is a

crucial factor for the survival of businesses in

today’s competitive world.

That’s why I’m proud to say that we have

unparalleled resources for R&D. We are deeply

committed to driving the air filtration industry

forward.

We research for our customers, realizing

value for them on a daily basis by develop-

ing new clean air solutions with the highest

efficiency, the lowest energy consumption,

the longest life and the least environmental

impact.

We discover and create new knowledge

about filtration technology that is focussed

on customer needs. This benefits their busi-

nesses and their end-users.

And we do more than develop filters –

we also design the production processes to

ensure that our filters are manufactured with

the highest quality, and to the most stringent

standards, at every Camfil Farr plant in the

world.

With sustained – and sustainable – R&D,

we are in a better position to sharpen our

competitive edge in an increasingly global

marketplace.

New R&D showcase in Sweden

Our technological advances, through R&D,

help poise us as a leader in filtration and clean

air innovation. This is why R&D investments are

essential for our future.

We maximize the benefits of R&D pro-

grammes by combining them with the right

type of investment, such as our new Tech

Centre in Sweden, described in this issue.

The new Tech Centre showcases our R&D

strength. It is the largest of our four R&D hubs,

all of which collaborate and exchange local

experience for global application.

With facilities like the Tech Centre and a

never-ending focus on development, Camfil

Farr is in a better position to tackle the

problems associated with poor air quality. By

investing in R&D for cleaner air, future gen-

erations will also have a healthier life and face

fewer environmental challenges.

But Camfil Farr is much more than

research. Inside, you can also read the latest

about diesel exhaust, learn about our interest-

ing project to analyze particulate and gaseous

pollutants on a busy Stockholm street, our col-

laboration with the State Hermitage Museum in

Russia, our Facebook server hall delivery, new

filter products and software, and customer

cases highlighting the advantages – and ben-

efits – of choosing Camfil Farr.

In Sweden, the Baltic coastal town of

Trosa is the birthplace of Camfil and the

Camfil Farr Group, where operations

started almost half a century ago, and

where the Swedish subsidiary manufac-

tures and distributes filters all over the

Nordic region and even internationally.

In late October 2012, the town was also the

stage for the official opening of one of the larg-

est R&D centres in the world for the develop-

ment of air filters, clean air solutions and filter

production technology.

This Camfil Farr facility in Trosa, called

the Tech Centre, is equipped with the lat-

est laboratory technology to analyze air and

develop high-performance filtration products

and systems.

Camfil Farr’s Road Show trailer was also

on location in Trosa for the official opening of

the Tech Centre. This unique travelling mobile

lab and exhibition has been touring Europe

under the “Clean Air – a Human Right?” banner

to spread knowledge about the importance of

filtration and filters, and the benefits for indoor

air quality (IAQ) and health. This rolling lab also

tracks air pollution levels in key cities.

R&D powerhouse

Around 30 filtration specialists and employees

work at this world-class R&D facility, which

develops filters and clean air solutions for the

Camfil Farr Group and customers.

The centre’s experts have PhDs in par-

ticle and molecular filtration, or degrees in

mechanical and chemical engineering, among

other fields.

R&D and other development activities

are carried out in six main sections of the

2,500-square-metre facility:

Molecular Lab: research and measure-

ment techniques for Airborne Molecular

Contamination (AMC) filtration solutions.

GT/APC Lab: Development of filtration sys-

tems for the gas turbine (GT) industry and

the Air Pollution Control (APC) segment (dust

collection systems). This lab is equipped with a

unique test rig for gas turbine filters developed

by Camfil Farr.

Process Development Workshop:

filters. Research here is focussed on filter effi-

ciency, performance and filter media. Aerosol

tests are conducted and the lab has an elec-

trostatic classifier with CPC for nano-particle

measurements.

Particle Lab 2: This facility has a test

rig to classify filters according to European

EN 779:2012 and U.S. ASHRAE 52.2 stand-

ards. The lab is used to classify the energy

consumption of filters and assess their lifetime

performance.

IAQ Lab: This lab for Indoor Air Quality (IAQ)

analysis is used to analyze air samples for

customer troubleshooting, problem solving

and air quality assessment. The microstruc-

ture of Camfil Farr filters is also investigated to

ensure the best possible filtration performance

and consistent product quality. Particles cap-

tured in filters are analyzed in a state-of-the-art

Scanning Electron Microscope (SEM), using

also EDAX (Energy Dispersive Analysis X-Ray)

and gas chromatography equipment.

Global R&D network

R&D has driven the Camfil Farr Group forward

over the years and helped position the com-

pany as the leader in air filtration and clean

air solutions.

In addition to the main innovation hub in

Trosa, the Group has local R&D facilities in

Germany for comfort air filters and clean room

filtration; in France and the U.S. for comfort

air systems; in Malaysia for comfort air, clean

room and AMC filtration, and in China for

comfort air filters.

“From these global R&D bases we can

research and develop products for the world-

wide air filtration market, including filters for

the gas turbine industry,” says Anders Sundvik,

Vice President for R&D.

“We also have a number of mobile lab

stations around the world to test filters right

on the customer’s premises, in virtually any

type of industry. Our filter research includes

the development of filters using the most

modern filter media, such as nano-fibres. We

also design and build our own filter production

equipment.”

This global R&D network ensures that

the product portfolio is steadily maintained,

improved and advanced across all Camfil Farr

business areas. It also drives the development

of new innovative filters and solutions. Preparation of filter samples from an IAQ testing device to analyze the particle content in Camfil Farr's SEM.

Maximizing customer value

“R&D on this scale maximizes value for our

customers,” continues Anders Sundvik. “We

collaborate and exchange our experience all

over the world between units. We develop the

products and even design the process to make

them. Customers get the optimum product for

their filtration needs in terms of efficiency,

energy consumption, life and environmental

impact.”

Training facilities

In addition to R&D, the Tech Centre is also

used for training and educating employees

and customers in filters and filtration technol-

ogy, among other subjects. The programmes

include both theoretical and practical training,

with the labs and technical equipment being

used for the latter.

Customers also visit the Tech Centre every

week to observe demonstrations of filters or

to learn more about solutions that have been

developed and tested for their specific filtra-

tion problem or need.

Adding expertise

As Camfil Farr has expanded its business,

it has broadened its filtration expertise to

serve customers in specific industries, most

recently, for example, for the important gas

turbine market.

“This market is expanding rapidly and we

have ramped up our facilities by building a

special lab and test rig for turbine filters, a

specialty of Camfil Farr Power Systems. We

use the rig to test our solutions by simulating

different climates and other extreme operat-

ing conditions to verify filter reliability and

performance, which is so vital for turbine life

and operation. This research has resulted, for

example, in the development of a brand-new

hybrid filter media for gas turbines, featured

in the new CamPulse GTD filter (page 5), says

Anders Sundvik.

“With the new Tech Centre in Trosa and

all our other innovation hubs in the Group, we

are well prepared to meet the needs of our

customers,” ends Anders Sundvik.

Why is R&D so important to Camfil Farr?

Anders Sundvik: Camfil Farr is a family

company with a huge interest and stake in

technology. We have made substantial invest-

ments in R&D since the start and we believe

it is one of the most important factors for our

future and the future of air filtration.

For example, our expertise covers all

disciplines in air filtration. Our techniques

for analyzing air quality are well known in

the industry. I can mention our particle

sampling methods and our ability to analyze

these samples with our SEM, EDAX (Energy

Dispersive Analysis X-Ray) and gas chroma-

tography equipment to determine the type

and size of particles, or the gas profile. This

gives us insight into the customer’s filtra-

tion problem and allows us to develop and

demonstrate the solution with our portfolio

of filters.

Who benefits?

AS: Our research benefits people through

the development of clean air solutions that

improve life quality, protect health and

enhance well-being.

Our filtration solutions protect customer

processes and improve their bottom line.

And the filtration industry benefits in gen-

eral because we advance the technology and

develop sustainable solutions that also save

energy and help cut waste.

Do you also network?

AS: In addition to exchanging experience

within the Group, we team up with the

academic world by working with universi-

ties, technical schools and other research

institutions in the medical, environmental or

scientific fields.

And we develop and advise on new

ISO, CEN and ASHRAE standards directly

– or through close collaboration – with

trade organizations for which several Camfil

Farr filtration specialists serve on, or chair,

professional committees and other work

groups. This enables us to cover all R&D

bases in our industry.

Researching for the future – 3 questions for Anders Sundvik, VP R&D

Anders Sundvik

With more than 40 years of experience as

a leading developer of filters and air inlet

systems for gas turbines, Camfil Farr Power

Systems has now taken pulse filters one step

further by extending the product line with

two new products – CamPulse™ GTC and

GTD. Both feature a new non-discharging fibre

media with unique filtration properties.

Like other products in the Power Systems

range, CamPulse GTC and GTD fully satisfy the

goal of turbine filtration – to optimize efficiency

and extend turbine life through protection from

dust and humidity.

Unique HemiPleat® technology

CamPulse GTC and GTD utilize Camfil Farr’s

unique patented HemiPleat technology. The

pressure drop is lower through the open and

wider pleat spacing, which also improves dust

release during pulsing and reduces energy

costs through fuel savings and a higher turbine

output.

More media is also available for filtration to

improve turbine performance and life. With the

non-discharging fibre media, the filters remain

highly efficient during their entire lifetime.

The durable synthetic media has a high dust-

holding capacity.

All these features give turbine operators

a lower cost of ownership for their filtration

system.

GTC for high humidity

Since daily fog can be an issue for self-cleaning

pulse filters, the CamPulse GTC is optimized to

maintain its low pressure drop during periods

of increased relative humidity.

GTD for desert environments

CamPulse GTD features a layer of nano-fibres

over the synthetic substrate to significantly

improve dust collection on the media surface

and dust release when pulsed. This filter

is deal for high dust environments such as

deserts and other arid climates.

CamPulse GTC and GTD are certified to

EN 779:2012, filter class F9, and ASHRAE

52.2-1999, MERV 16. Both are available in

cylindrical and conical versions for easy

replacement. They come in a double package,

with two filters in one unit, for optimized stor-

age and half the shipping cost.

GTC and GTD media are also available in

Tenkay versions.

Keeping the city

OUTExhaust fumes, diesel particulates and

ozone are making city air worse and

lowering air quality considerably. As

described in this issue, sulphur dioxide,

nitrogen oxide and other air contami-

nants are creating serious health prob-

lems. At the same time, regulations are

becoming stricter.

Camfil Farr’s “City” series of molecular filters

for urban pollution – City-Flo XL®, CityCarb®,

City-Flo® and CitySorb® – represent the

ultimate filtration solution for indoor air qual-

ity control. These filters combine a high-

performance particle filter and highly effec-

tive broad-spectrum carbon filter in a single

device.

For example, CityCarb and City-Flo are

used for enhanced IAQ and odour control in

comfort ventilation applications. The extra

energy-efficient City-Flo XL has been devel-

oped to achieve a better indoor environment.

CitySorb is used for adsorption of gases and

odours in systems with existing particle filtra-

tion.

These filters, specially developed for build-

ings in urban environments, are extraordinarily

effective against exhaust fumes and smells.

They are also energy-efficient. Along streets

and roads that have heavy traffic, City filters

are ideal for use in office complexes, shop-

ping centres, schools and other public build-

ings. They contain highly activated carbon

to remove a wide range of volatile organic

compounds.

No modifications are needed to air

handling units (AHUs) to install City filters,

which are used instead of ordinary bag filters

in metropolitan areas where air pollution is a

concern, and where higher indoor air quality

(IAQ) is desired to protect health and provide a

better work environment.

First ozone-rated filters

Camfil Farr also introduced the first system

in the filtration industry for rating the ozone

removal efficiency of air filters.

The rating system allows customers to

assess the effectiveness of City molecular

filters, which also effectively remove ozone,

considered to be one of the most serious

threats to human health.

The ozone removal rating can be fac-

tored into the decision-making process to

ensure that good IAQ is also achieved from

a molecular perspective. The ozone removal

rating informs customers more about the per-

formance of Camfil Farr’s molecular filters and

helps customers understand the full benefit of

selecting Camfil Farr products for air handling

units.

Is your home really your shelter? Indoor air

can be up to 50 times more polluted than

outdoor air. That’s why ventilation systems are

important for mitigating indoor air pollution,

and that’s why we need effective filters in air

handling units to keep dirty outdoor air from

infiltrating buildings, especially in polluted

urban areas.

This is one of the main messages of Camfil

Farr’s ongoing Road Show, which has been

travelling in more than ten countries in

Northern and Southern Europe under the

b anner “Clean Air – a Human Right?”.

This unique “rolling” Mobile Lab and exhibi-

tion is housed in a 13-metre-long eco-friendly

trailer, complete with live measurement sta-

tions to show local air quality. It’s the perfect

venue for learning how air affects you and your

health, and how air filtration benefits people.

In mid-2012, the International Agency for

Research on Cancer (IARC) – part of the World

Health Organization (WHO) – classified diesel

engine exhaust as carcinogenic to humans.

To draw this conclusion, IARC experts in

Lyon, France, had analyzed published studies,

evidence from animals and limited research

in humans. The research findings indicate a

need to focus on managing human exposure

to diesel exhaust.

IARC’s press release rocked the news

world and has been one of the biggest health

stories in 2012.

In essence, IARC declared that diesel

fumes cause lung cancer and are more

carcinogenic than second-hand cigarette

smoke. Twenty-four years ago, IARC said

diesel exhaust was “probably carcinogenic”

but has now reclassified diesel exhaust based

on what it calls compelling scientific evidence.

The organization’s decision is the first to

elevate diesel to the known carcinogen level.

This implies that diesel exhaust now shares

the WHO’s Group 1 carcinogen status with

smoking, asbestos, ultraviolet radiation, alco-

hol and other elements that cause cancer risk.

In Greek mythology, Aether was a god

that created air. He breathed the purer

upper air of the deities, as opposed to

the ordinary “stuff” that the lungs of

mortals were entitled to.

But in Sweden, Aether has resurrected as

the name of a project being conducted by

a team of experienced Camfil Farr filtration

experts in association with two departments

at Stockholm University. The objective is to

document the ability of particle and molecular

air filters to capture and remove harmful parti-

cles and gases along Hornsgatan, a Stockholm

street with a bad reputation for heavy traffic

and polluted air.

In January 2010, the same street became

the first in Sweden to ban the use of studded

snow tires during the winter months in order

to reduce the amount of particles ripped up by

the metal studs, which increases air pollution.

Hornsgatan has the highest particle measure-

ments in Stockholm, with limits being exceed-

ed as many as 58 times a day in 2011 alone.

University network for R&D

collaboration

Collaborating with prominent universities and

research institutions around the world is part of

Camfil Farr’s activities to develop leading-edge

clean air solutions. For the Aether Project,

two experts from Stockholm University are

co-operating with Camfil Farr’s filtration spe-

cialists at the Tech Centre in Trosa, Sweden

(see page 3): Ulf Rannug, Professor at the

Department of Genetics, Microbiology and

Toxicology, and Roger Westerholm, Associate

Professor at the Department of Analytical

Chemistry.

Prof. Rannug is recognized for his research

on the health and carcinogenic effects of

diesel exhaust and other environmental pol-

lutants. Prof. Westerholm is known for his

research on the chemical characterization

of pollutants from mobile sources and other

research related to vehicle fuels and urban air

pollution.

Fine particles

PM2.5 and PM10 particles are one of the main

concerns in Stockholm. PM10 are particles

smaller than ten-thousandth of a millimetre

from tires, or from metals, soot, acids, pollen

and moulds.

The smaller microscopic PM2.5 particles

(tinier than 2.5 µm), which are exhaust and

combustion particles or diesel particles from

vehicles, are small enough to evade the body’s

mechanism and pass into the airways and the

lungs and blood.

PM2.5 particles affect respiratory health

when people breathe high levels of particulate

pollution. Coughing and wheezing are symp-

toms. Others are lung damage, which may

lead to premature death in individuals with

heart or lung disease, and aggravated asthma

attacks in children. There is a direct connec-

tion between fine particles (<2.5 µm) and

increased mortality caused by cardiovascular

and respiratory illness.

In Stockholm, wear-and-tear of street sur-

faces during heavy winter traffic periods is a

source of particulate pollution. Other sources

are particles from vehicle brakes and exhaust

and sand spread during the winter for traction

on icy sidewalks. However, street traffic and

wear represent the largest source, accounting

for approximately 85% of all particles, which

has caused alarms in a city known for its

strong environmental profile.

After almost three years of banning the

use of studded tires on Hornsgatan, the City

of Stockholm might also prohibit them on other

streets where traffic is heavy.

Testing particle and molecular filters

Due to growing public and governmental

concerns about urban air quality and the intro-

duction of new standards for filter efficiency,

such as EN 779:2012, the Aether Project will

also investigate how particle and molecular

filters remove harmful polycyclic aromatic

hydrocarbons (PAHs), a chemical contaminant

found on particles and in the gas phase of

pollution. PAHs are common in areas with high

rates of motor vehicle traffic.

The exhaust from diesel engines includes

several air pollution components such as ultra-

fine soot particles, smaller particles, nitrogen

oxides and organic compounds like PAHs, all

of which are believed to play an important role

in the link between diesel emissions exposure

and respiratory ailments.

First tested in 1985

Camfil Farr first tested the ability of air filter to

remove genotoxic (carcinogenic) substances in

outdoor air in 1985 using the Ames test and a

specially designed aerosol tester.

For this project, Camfil Farr also teamed

up with Professor Rannug and the experiment

was made by placing the test unit in an outdoor

air intake of a building in downtown Stockholm.

The original test clearly showed how geno-

toxic substances decrease with increased

filter efficiency. However, the development

of new filter media and designs, notably

molecular filters, now makes it interesting to

evaluate the filters again by expanding the test

procedure to include chemical analyses, as

well as tests on both particulate and gaseous

contaminants.

The Ames test will be used again to assess

the genotoxic characteristics of the pollutants.

For the 2012 test, Camfil Farr is providing the

filtration expertise and test rig and Stockholm

University is performing genotoxicity tests

chemical analysis.

Ongoing project

The test was launched in autumn 2012 and

we will report on the findings in a future issue

of AirMail.

Test rig in Stockholm

The test rig in Stockholm (photo below) is

placed in a specific location on Hornsgatan

that takes into account pollutants, the pres-

ence of existing ventilation systems and the

rig’s proximity to Stockholm City’s official

pollution monitoring sites.

The rig is equipped with five cylinders with

a series of different filter media with efficien-

cies ranging from 20% to 90% on 0.4 µm par-

ticles. Activated carbon will be used to remove

gaseous contaminants.

Air samples will be analyzed later in Camfil

Farr’s state-of-the-art scanning electron micro-

scope at the Tech Centre in Trosa (see article

on page 3 of this issue). Stockholm University

will determine the content of PAHs removed

by the filters.

The following contaminants are being con-

tinuously measured at the site: NOx, NO, NO2,

CO, O3, soot and PM1, PM 2.5 and PM10 par-

ticles. A particle counter will register particle

sizes on site, from 10 nanometres in size and

larger, and in 16 different fractions. All of these

test parameters will provide solid background

data for measuring results.

Other than measuring the efficiency of

particle and molecular filters on vehicle-

generated particles and gases, the findings

will most likely make Stockholm’s traffic and

environmental management planning even

more “street smart”.

SEM photo of a filter sample from the Hornsgatan test unit

using an IAQ screening device. The majority of the small

particles are from combustion while the larger particles are

mainly pollen, gravel or sand.

The rig is equipped with five cylinders with different filter media with efficiencies ranging from 20% to 90% on 0.4 μm particles. Activated carbon will remove gaseous contaminants.

A good initiativeThis initiative by Stockholm City to improve inner city air is highly interesting to Camfil Farr

because of our belief in the importance of air quality for human health.

We are particularly interested in mapping the harmful effects of submicron particles

– those as small as PM1 – that enter the lungs and blood when breathed.

Camfil Farr intends to focus future efforts to research this problem further, using the

Ames test and advanced laser particle counters to measure the particle mass concentra-

tions in city air, as well as to quantify particle sizes and the number and composition of

particles.

In combination with these R&D efforts, we will also analyze molecular contaminants

as a basis for additional future measurements in this research area.

In 2011-2012, Camfil Farr filtration

specialists have been participating in

the development of scientific and design

documentation for the restoration and

repair of the heating, ventilation and

air conditioning (HVAC) systems serving

Petrovsky Hall on the second floor of

the Winter Palace – one of five buildings

belonging to the world renown State

Hermitage Museum complex in Saint

Petersburg, Russia.

The aim of this co-operation is to introduce

eco-friendly filtration technology and increase

the energy efficiency and sustainability of the

HVAC systems. This project has involved meas-

uring air quality in the room and ventilation

systems, verifying the operation of air handling

units, and changing out filters to Camfil Farr’s,

which have higher efficiencies, greener pro-

files and lower energy consumption.

Camfil Farr’s scanning electron microscope

unit, located at the R&D Centre in Sweden,

is also being used to analyze filters and

materials.

On the basis of this research, Camfil Farr

has proposed solutions to improve the air

quality in Petrovsky Hall from 2012 to 2014.

Other State Hermitage projects

In addition, a contract has been signed to

develop the scientific and design documenta-

tion for the restoration and repair of the HVAC

systems serving the Great Church of the

Winter Palace.

In the framework of the ongoing scientific

cooperation with State Hermitage Museum,

Camfil Farr specialists have also been invited

to participate in a seminar titled “Climate

Control in the Museum – The Conservation of

the Cultural Heritage”, part of the museum’s

International Research and Practice Conference,

to be held January 30-February 1, 2013.

“This long-term collaboration is a mutual

learning itinerary for both State Hermitage and

Camfil Farr and we are pleased to be engaged

in projects for such a prestigious museum,”

says Lennart Schröder, President of Camfil

International.

“State Hermitage is focussed on green

technology and energy efficiency and we can

help with this all-important sustainability ques-

tion to preserve one of the most spectacular

collections of art and treasure in the world,”

he ends.

Facebook has located its new huge data

centre just below the Arctic Circle in

Luleå, in the far north of Sweden, for

a number of strategic reasons. One is

naturally to provide faster service to

Europeans – it’s the social networking

company’s first data centre outside the

U.S. – but another is the advantage of

the cold climate to keep racks of high-

performance computer equipment cool

at a considerably lower cost and with a

smaller carbon footprint.

A reliable supply of electricity was another

motive: Luleå is located near hydropower

stations on a river that generates a lot of

electricity and the local power grid has not

experienced a disruption since 1979. The cold

climate and reliable power supply also means

70% fewer backup diesel generators, com-

pared to Facebook’s other centres, for less

carbon emissions.

Cool climate is attractive

Facebook has more users outside the United

States than inside and the Web company

decided it was time to expand in Europe. A

node for data traffic on the European continent

gives European users faster performance and

also provides backup resources.

The Luleå data centre is a 28,000-square-

metre server building that will be finished in

March 2013.

Winter temperatures in the north of

Sweden are well below freezing and the tem-

perature is rarely above 25°C in the summer.

The climate is beneficial for heat-producing

server racks that require constant cooling.

Bravida supplies HVAC and building

systems

Bravida – Scandinavia’s premier integrated

supplier of technical installations and service

solutions for buildings and plants – was sub-

contracted by the main contractor, NCC, to

supply all electricity, heating, plumbing and

HVAC systems for the data centre in Luleå.

To meet the need for cooling in the centre,

Bravida is supplying a system that will rely

solely on a cooler based on outdoor air and

misting, a method known as evaporative cool-

ing. However, for eight months of the year, the

plant will actually cool itself with cold outdoor

air. Heat from the server racks will also be

used to warm up the offices there in winter.

This solution will make the high-tech centre

one of the most energy-efficient in the world.

Facebook says that energy consumption at

the data centre in Luleå will be 38% lower,

compared to its other server centres.

Two banks with 1,320 Opakfil™

Energy filters

For the HVAC system, Bravida teamed up with

Camfil Farr for the all-important filtration solu-

tion – a total of two filter banks, each equipped

with 660 Opakfil Energy filters. AeroPleat®

Eco is being used as pre-filters.

Filtration is highly important because of

the large amount of outdoor air used to cool

the server buildings and requirements for a

dust-free operating environment.

Cold outdoor air is introduced in the server

hall and mixed with heated air to the right

temperature. After the pre-filtration stage with

AeroPleat Eco, the air is filtered again through

the two banks of Opakfil Energy filters. After

that, the air is “misted” to obtain the right

humidity level. Fans distribute the air to an air

lock in the server hall where it is passes over

the servers to cool them. Each rack has three

levels with 30 servers in each and backup

batteries.

Roche, an innovator in healthcare and the

world’s biggest biotech company, has pio-

neered many medical breakthroughs in-vitro

diagnostics and drugs for cancer and trans-

plantation. Specialties in therapeutic areas

include autoimmune and inflammatory diseas-

es, virology, metabolic disorders and diseases

of the central nervous system.

This research-based company was looking

for a dust collection solution at its Leganés

(Madrid), Spain plant, where six rooms for

tablet production are equipped with five Fette

2090 rotary presses and one Fette 3090.

The company initially planned on using a

competitor’s dust collector for dust extrac-

tion. This installation was to include a bag-in/

bag out (BIBO) system for the filter cartridges

and a continuous line discharge system for the

collected dust.

However, Roche prioritizes health and

safety in production plants, and due to the

toxic characteristics of the dust and the possi-

bility of dust explosions, the company decided

that the design needed improvement since one

single collector might result in cross-contami-

nation of the six rooms.

Six energy-saving collectors instead

Roche Spain contacted Camfil Farr, which pro-

posed one dust collector per room. With this

design, Roche could use the dust collectors

independently, as required by production in

each room, to save energy.

Roche is now using six Gold Series GSC02s

with explosion vents, the BIBO safe change

system for cartridges, and double butterfly-

valve continuous line discharge for dust con-

tainment. The distance from the collection

point to the dust collectors, and the relatively

small air flow, required only medium-pressure

fans for greater energy savings.

Operator safety is of is one of the highest

priorities in the pharmaceutical industry. The

high-build quality, efficient filtration and safe

change features of Gold Series dust collectors

fully address these issues.

Sycatec installed the collectors, and the

fast and efficient collaboration between Roche,

Camfil Farr and Sycatec resulted in a highly

effective dust collection solution in Spain.

Camfil Farr has won the Nobelux Environment

Award for General Sustainability for 2012.

Anders Flanking, State Secretary to the

Swedish Minister for the Environment, pre-

sented the prize to Myriam Tryjefaczka, Camfil

Farr’s Corporate Sustainability Officer, at the

Nobelux awards ceremony, held during the

autumn in Brussels.

“Camfil Farr has been recognized as an

industry leader in sustainability and eco-effi-

cient filtration solutions for years. This has

been accomplished by managing product per-

formance and energy efficiency proactively

instead of reactively. As a result, we supply

healthy indoor air while helping customers to

save energy and reduce their environmental

footprint. ‘Walking the talk’ is key aspect of the

Camfil Farr Group’s commitment to sustain-

ability. We keep on reducing our environmental

impact and resource intensity. Several of our

factories have also been the first in their coun-

try to receive energy management certifica-

tion according to EN 16001 and ISO 50001,”

said Myriam Tryjefaczka when receiving the

award.

Nobelux is a Swedish Chamber of

Commerce for Belgium and Luxembourg that

AstraZeneca’s manufacturing site in Södertälje,

Sweden, just south of Stockholm, is the phar-

maceutical company’s biggest production and

supply unit and one of the largest oral solid

dose production sites in Europe.

For many years Camfil Farr has sup-

plied the plant with comfort air filters and

Cambox housings with bag-in/bag-out (BIBO)

tech nology.

Today, this fruitful collaboration has been

broadened to include HemiPleat® Nano cart-

ridge filters to upgrade the filtration efficiency

of dust collectors for a demanding tablet coat-

ing application.

HemiPleat vs. competitor filters

AstraZeneca had been using a competitor’s

filters in the dust collectors for the coating

line. Since replacement filters for dust col-

lectors were an area that Camfil Farr has

not worked with AstraZeneca before, a com-

parison test was arranged with our cartridge

filters, which feature state-of-the-art HemiPleat

pleating technology and a nano-fibre layer.

HemiPleat filter media use synthetic beads

to hold the pleats of the cartridge open.

The pleat spacing is therefore wider than in

competitive cartridges, which are packed too

tightly to maximize media use. In HemiPleat

more dust, creating a safer and cleaner work

environment.

Higher efficiency and longer life

The test proved the superior performance of

HemiPleat. Today, more than 1,120 HemiPleat

Nano replacement cartridges are in operation

in Södertälje today, with Astra Zeneca benefit-

ting from reduced pressure drop for energy

savings, improved filtration efficiency, longer

filter life with nano-fibre technology, and lower

maintenance and life cycle costs.

HemiPleat filters, part of the Camfil Farr

Cardiothoracic surgery is highly complex

and requires the most sterile operat-

ing conditions to prevent post-operative

infection. Camfil Farr’s CamHosp-R

ceiling for operating theatres is specially

designed to meet the highest surgery

standards, as exemplified by a recent

precision delivery to a hospital centre

near Paris, France.

The hospital needed a new operating theatre

ceiling with a vertical, unidirectional air flow.

Other requirements included fast delivery – a

new surgical team was about to join the staff

– and a comfortable, noiseless and no-draught

work environment. Low energy consumption

was important. Technical constraints were

also challenging, such as the low height of the

ceiling in the theatre.

Versatile solution

Camfil Farr’s CamHosp-R ceiling is designed

for a risk 3 or 4 rate according to the NFS

90-351 standard for operating room ventila-

tion. It features a remote, unidirectional air-flow

ceiling with recirculation air unit. The system

is equipped with two filtration stages: F7 recir-

culation inlet filters (A-rated according to the

Eurovent energy efficiency classification sys-

tem) and Absolute® high-efficiency particulate

filters for the air flow over the operating table.

Meeting the fast deadline for the installa-

tion was extremely challenging. Usually, the

air handling unit for a ceiling system is located

outside the operating room and, because of

the high volume of air that needs to be treated,

the air ducts are large and the installation

work is complex. With CamHosp-R, everything

is placed in the same room, making the installa-

tion much simpler, quicker and less expensive.

Other advantages of CamHosp-R

CamHosp-R offers other advantages. Instead

of the four fans used in most solutions, Camfil

Farr’s ceiling has six to reduce the operating

mode and noise. An integrated and specially

designed Camfil Farr silencer also lowers the

sound level substantially.

While most ceiling systems operate around

the clock, the CamHosp-R ceiling system at

the hospital can be put on standby mode from

9 p.m. to 6 a.m. to save energy. The recircula-

tion system is turned off but a continuous flow

of fresh air is used to maintain overpressure in

the room. If needed, the recirculation system is

reactivated and the room can be made ready

for surgery within minutes.

Fresh air is precisely mixed with room air

to keep the air flow temperature even. Above

the patient, the air flow is perfectly controlled

and efficiently filtered through Camfil Farr’s

Absolute filters. The rest of the room benefits

from the treated air and there is no turbulent

air flow. As the air supply is extremely clean,

the filters have a long life expectancy and their

very low pressure drop also reduces energy

consumption.

With CamHosp-R, the hospital’s cardio-

thoracic surgery centre now has a versatile,

flexible and future-proof operating theatre that

conforms to the strictest operating and quality

standards.

In the U.S., Verizon Wireless Arena (Manchester,

New Hampshire) is New England’s premier

indoor sports and entertainment venue.

Located in an urban environment, the

arena takes in large amounts of outside air.

Air handing units (AHUs) only run about 1,800

hours per year, but air flow demands are high

during operating hours. “Monster truck” shows

and other motocross events especially contrib-

ute to high filter loading.

The arena changed its pleated filters twice

a year, and MERV 13 fine-fibre final filters

(metal frame) once a year, but now wanted a

new filter solution to cut labour and operat-

ing costs while maintaining high air quality.

Reducing filter disposal and landfill costs was

another goal.

Camfil Farr performed Life Cycle Cost

(LCC) modelling on the existing filter pro-

gramme and proposed a one-stage filtration

solution using a Hi-Flo ES MERV 13 bag

filter that eliminated the need for a pre-filter.

LCC results indicated a 12-month service life

using the Hi-Flo ES.

Benefits

The typical velocity for the filters is about

400 cfm (about 680 m3/h) and most AHUs

operate with 100% outside air. At six months,

the bag filters showed uniform loading and

only the smallest rise in pressure drop. Camfil

Farr has also projected that the Hi-Flo ES will

most likely last as long as 18 months, well past

the guaranteed threshold of 12 months.

The Hi-Flo ES maintains uniform loading

– even in harsh and moist New Hampshire

weather – lowers the total cost of ownership

and maintains consistently high efficiencies.

The energy savings is more than USD 30

(about EUR 23) per filter and the arena has

forecasted a 75% net reduction in disposal

and landfill costs. The same particle removal

efficiency is maintained with a 45% reduction

in annual costs. The conversion has also cut

energy consumption by 56% (14,918 kWh),

CO2 emissions by 56% and landfill costs by

84%.

Verizon Wireless Arena is managed by

SMG, a major national facility management

organization.

In the European market, the filter equivalent to the Hi-Flo® ES is the energy-saving Hi-Flo XLT™.

Road Show at top political event

The Association promotes the use of sound and healthy ventilation in residential and commercial building. Its slogan, dis-played here on a mini air ship balloon, is “Our future hangs in the air”.

This year the Swedish Association of Air Handling

Industries borrowed Camfil Farr’s Road Show trailer

and exhibition for a top political event in Visby, on the

Swedish Baltic Sea island of Gotland.

The event, called “Almedalen”, is one of the largest

for Swedish politicians and offers a unique opportu-

nity to voice different concerns. In 2012, there were

1,900 events on the official programme that attracted

900 organizers and 14,000 people.

The trailer was used to promote the importance of

good ventilation and indoor air quality (IAQ). Specialists

from Camfil Farr and a number of Swedish HVAC prod-

uct manufacturers were on hand. Representatives

from the Swedish Asthma and Allergy Organization

also joined the show.

The Association also organized a seminar together

with politicians from Riksdagen, the Swedish parlia-

ment, to discuss tougher regulations for IAQ in schools

and public buildings, and the importance of air filtra-

tion and good ventilation. Several regulatory agencies

for work environment regulations and new building

standards also attended the event.

Unique mobile lab and exhibition

The Road Show trailer is unique and the Almedalen event is an example of how Camfil Farr promotes IAQ and

sustainable air filtration solutions by collaborating with industry members and trade organizations.

The Road Show has been touring Scandinavian and European cities. Our website, www.camfilfarr.com/

Campaigns/Camfil-Farr-Road-Show/, shows the tour schedule and gives you complete information about the

Road Show. you will also find the Road Show on Facebook. Find out if we are visiting a city near you!
