1.2.- EF Tubular fan

Main feature of EF fans is its tubular design with inlet and outlet flangedcasing. This simple circular design, allows these fans to be easily in-stalled in ductwork.

They are a powerful tool in the hands of ventilation systems designers,as they can cover a wide range of pressure and capacity and at thesame time they can keep space requirements small due to the wide va-riety of suitable options.

Casing

The casing is built in strong welded sheet. For fans with impeller inaluminium up to size 1000 mm, the standard coating is done by ca-thode epoxy paint RAL 7045 and cataphoretic cycle and subsequentbaking at 170°C. For sizes over this diameter the casing is hot dip gal-vanized. Fans with impeller with steel hub are hot dip galvanized forany size.

Impeller

EF tubular axial fans, can either be found with full aluminium impeller or with steel hub impeller completed with aluminium blades.More information about the main differences and advantages of those two kinds of impellers can be found in paragraph 3.2. When design conditions allow that, full aluminium impellers become an optimal cost save solution. Both direct and belt driven EFaxial fans, can be selected with aluminium impellers for diameter up in 310 mm to 1400 mm. When installation requirements go over aluminium engineering limits, steel hub impeller with aluminium blades need to be used.This type of impeller represents a perfect solution for high performance applications. Available steel hub impellers for EF fans coverthe range between 900 mm and 1800 mm diameter impeller for direct driven fans and between 900 mm and 2000 mm diameterimpeller for belt driven fans.

Arrangements

The EF axial tubular fans are the only one kind of fans available either in belt or direct drive mode.

Direct driven

In this kind of construction the motor is supported by a base tightly anchored to the fan casing. Air can flow from motor to impeller(standard solution) or from impeller to motor, but anyhow the motor is involved by fluid stream. This fact state the temperature rangeof the air flow to the limits recommended by motor manufacturer, normally between -20°C to 40°C. Direct driven fans are able to match working conditions through the regulation of pitch angle (see section 3 in page 17).

13


Belt driven

In this arrangement the motor is set it out of the air flow stream. Torque and rotational motion is transferred from motor to impellerthrough a belt and pulleys transmission. In this situation pulleys are not completely isolated from motor flow, so that states the ma-ximum temperature of the flow running through the fan to 60°C.

EF fans with aluminium impellers shall be supplied in arrangement 9,with motor supported by fan casing. Support feet can be supply on de-mand when the fan is requested to stand itself.

EF fans with impeller with steel hub and aluminium blades, normallyneed higher motors sizes to support performance demanded. As notall the motor sizes can be sustained by fan casing, some of these fansshall be provided with base frame to sustain heaviest motors. Informa-tion about maximum motor size suitable for any arrangement and forany fan can be found in the engineering data section of the catalogue.Support feet can be supply on demand when the fan is requested tostand itself, keeping the arrangement 9.

1.3.-ES bell shaped fan

Its special bell shaped casing converts this axial fan in the perfect solution for allnon ducted inlets systems. It increases efficiency and reduce noise emissionsby minimizing fan entry losses.

The adjustable pitch angle and the wide range of appropriate motors let designengineers to find a suitable model for any requested performance.

Casing

The casing is built in strong welded sheet. For fans with impeller in aluminium upto size 1000 mm, the standard coating is done by cathode epoxy paint RAL 7045and cataphoretic cycle and subsequent baking at 170°C. For sizes over this dia-meter the casing is hot dip galvanized. Fans with impeller with steel hub are hotdip galvanized for any size.

Impeller

ES bell shaped axial fans, can either be found with full aluminium impeller or withsteel hub impeller completed with aluminium blades. More information about the main differences and advantages of those two kindsof impellers can be found in paragraph 3.2.

When design conditions allow that, full aluminium impellers become an optimal cost save solution. ES can be selected with alu-minium impellers for diameter up in 310 mm to 1400 mm. When installation requirements go over aluminium engineering limits, steel hub impeller with aluminium blades need to be used.This type of impeller represents a perfect solution for high performance applications. Available steel hub impellers for ES fans coverthe range between 900 mm and 1800 mm diameter impeller.

Arrangements

Direct driven

In this kind of construction the motor is supported by a base tightly anchored to the fan casing. Air can flow from motor to impel-ler (standard solution) or from impeller to motor, but anyhow the motor is involved by fluid stream. This fact state the temperature

range of the air flow to the limits recommended by motor manufacturer, nor-mally between -20°C to 40°C.

Direct driven fans are able to match working conditions through the regula-tion of pitch angle (see section in page …).Support feed shall be supplied on demand when fan is requested need tostand itself. Safety protection net in the fan inlet is recommended to prevent any kind ofinjures. For more information about options and accessories see section 6,accessories.

1.4.- EB high temperature fan

This fan represents the solution for applications where air temperature go over 60°C. The motor and the transmission completelyisolated from air stream, let it deliver air at temperatures up to 180°C.

Casing

The casing is built in strong welded sheet. For fans with impeller in aluminium upto size 900 mm, the standard coating is made by cathode epoxy paint RAL 7045and cataphoretic cycle and subsequent baking at 170°C. For sizes over this dia-meter the casing is hot dip galvanized. Fans with impeller with steel hub are hotdip galvanized for any size.

Impeller

EB high temperature axial fans, can either be found with full aluminium impelleror with steel hub impeller completed with aluminium blades. More informationabout the main differences and advantages of those two kinds of impellers canbe found in paragraph 3.2.

When design conditions allow that, full aluminium impellers become an optimalcost save solution. EB can be selected with aluminium impellers for diameter upin 350 mm to 1400 mm. When installation requirements go over aluminium engineering limits, steel hubimpeller with aluminium blades need to be used. This type of impeller representsa perfect solution for high performance applications. Available steel hub impellersfor EB fans cover the range between 900 mm and 1800 mm diameter impeller.

Arrangements

Belt driven

In this arrangement the motor is set it out of the air flow stream. Torqueand rotational motion is transferred from motor to impeller through a beltand pulleys transmission. In this situation the transmission is completelyisolated from motor flow, so the maximum temperature the fan could reachis 180°C. These fans are normally supplied in arrangement 9 with motor supportedby fan casing. However, sometimes for the biggest sizes arrangement 12with baseframe could be possible. Information about maximum motor sizesuitable for any arrangement and for any fan can be found in the engi-neering data section of the catalogue.Support feet can be supply on demand when the fan is requested to standitself, keeping the arrangement 9.

3.- Blade pitch

Direct driven axial fans are supplied with fixed, set in plant, blade pitch. However, to cover expansion or reduction in air needs, bladepitch (blade pitch for steel hub impeller is shown in figure) for direct driven axial fan may be changed. In fact, performance curvemoves up or down in the charts when blade pitch changes. As this increment in the pitch would increase the absorbed power offan too, before changing it, it’s very important to verify that power of installed motor can cover new power absorption.Precise information about the procedure for blade pitch adjustment can be found in the manual “Warning and instructions for use”supplied with fans.

Frequency drivesStandard motors up to size normally 250 can be driven by frequency converter without any modification, but duty cycle need to bechecked. Motors over size 250 driven by frequency converter need to be reinforced.

FurnishingFans are normally supplied with motor. On demand is possible provide fans without motor or even assembly motors sent by customersin our plants.

WindingNormally wound for 50 Hz (suitable to be fed at 60 Hz with the right voltage), on demand special winding for 60 Hz. See next paragraph.

VoltageMotors supplied with Ferrari fans are wound for a rated supply of 50 Hz and for two different voltages according to the Star or Delta win-ding connection. For motors size <132 the standard voltage is 230 VΔ / 400V Y. That means that the fan can be used at voltage 230 V set-ting connection or at voltage 400 V using Y connection. For motors size ≥ 132 the standard voltage is 400VΔ /690V Y. That means thatthe fan can be used at voltage 400 V setting Δ connection, or at voltage 400 V using Y connection. Permitted tolerance for voltage is ±5%. When those motors, wound for 50 Hz, are connected to 60 Hz supply, speed will increase by 20% with reference to speed at 50 Hz. Newperformance values will change according to voltage supplied at 60 Hz using the multipliers shown in the following table (indicative data):

For any other supplied voltage, next formulas can be used:

V50 = Rated voltage at 50 Hz V60 = Rated voltage at 60 Hz N50 = Speed at 50 Hz N60 = Speed at 60 Hz P50 = Power at 50 Hz P60 = Power at 60 Hz I50 = Current at 50 Hz I60 = Current at 60 Hz M50 = Torque at 50 Hz M60 = Torque at 60 Hz

Performance curves for direct driven axial fans working at 60 Hz haven’t been obtained by direct testing but choosing the suitable bladepitch angle in order to replicate performance of fans working at 50 Hz.

Impeller diameter. Fan size is constant for every curve. Fan size is defined by impeller diameter.

Pitch angle and suitable motorFor direct driven fan is not possible to choose the speed of the impeller as it have to follow the synchronism speed of motor. This speedis about 3600 r.p.m for 2 poles motor, 1800 r.p.m for 4 poles, 1200 r.p.m for 6 poles motors and 900 r.p.m for 8 poles motors. This fact couldmake difficult sometime to find a fan suitable to match the operation point. To solve this problem, performance curve of a fan can be mo-dified by changing the pitch angle of its blades. Increments of pitch angle will move the performance curve up in the chart and pressureand capacity will increase and so the absorbed power of the fan. Fan diameter and speed are constant for every chart and three curves (three for performance, three for efficiency and three for absorbedpower) with three different pitch angle matching the right motor have been plotted.

Shaft power curvesThis curves shown the absorbed power of the fan. These curves follow the formula:Those curves locate in the charts standardized motors power data. To know the absorbed power of a fan working point placed betweentwo curves, interpolation may be done. For a more precise value, the next formula can be use:

W= Absorbed power in Kw V= Air delivered in m3/s, shown in the capacity axis Pt= total pressure in Pa, shown in the pressure axis ηt= Efficiency of the fan as read in the chart in %There are three different curves corresponding to three different pitch angles.

Sound pressure levelIt indicates the sound pressure at 1,5 m distance from the fan with free inlet and outlet ducted, weighted considering scale A. This scaleconsiders the perception of sound by human ear. The units for sound pressure level are dBA.

Efficiency curveThis curve represents the total efficiency of the fan. That means the rate between the final energy received by the air and the energy sup-plied to the shaft of the fan. This efficiency reflects the losses into the fan but not the losses in drive.

Fan speedIt indicates the rotational speed of the impeller. This speed is constant for any chart.

Performance curveThis is the most representative curve of the fan. It shows the total pressure provided by the fan for a range of capacities. The point of in-tersection of the system curve and the performance curve determines the operating point of the fan. The curve doesn’t cover the entirerange from free delivery (no obstruction to flow) to no delivery, but only the useful zone of the curve where the efficiency is higher. The se-lection of the fan shall assure that the operating point of the fan lies in the useful zone. A fan working out of this zone could create insta-bility or overheating of the motor drive. There are three different performance curves corresponding to three different pitch angles.

Dynamic pressure lineThis line represents the dynamic pressure of the fan. For a given capacity this pressure doesn’t change and is readable in the pressureaxis. This dynamic pressure can be calculated using the formula Pd= ρ v2/2, where ρ is the density (1,226 Kg/m3) and v the velocity ofthe fluid.

Pressure AxisThe ordinate axis shows the pressure of the fan in kgf/m2 units.

Capacity Axis The abscissa axis shows the pressure of the fan in m3/s units. Example: the figures shows a fan diameter 400 mm working with a 2 poles motor (3600 r.p.m) . The selected operating point will have the next characteristics:- Capacity: 1,95 m3/s, as shown in abscissa axis- Dynamic pressure: 16.5 kgf/m2 This value is shown by the projection in the ordinate axis of the intersection between the line corre-

sponding to capacity and the dynamic pressure line. - The total pressure is 37 kgf/m2 as seen in pressure axis, by the projection in the ordinate axis of the intersection between the line cor-

responding to capacity and the performance curve. It’s possible now to read the pitch angle, at the bottom of the performance curve. Inthis case the angle is 18°.

- The efficiency is visible in the second chart and is 70%, considering the efficiency curve for 18°. - Is possible to read the absorbed power in the top chart, using always the curve corresponding to 18°. The absorbed power is 1,05 Kw.

At the bottom of the curve is possible now to read the code corresponding to the angle, that is 6 in this case for angle 18°. The complete code of the fan will be then EF 406/G and the installed motor 1,1 Kw.

Impeller diameter. Fan size is constant for every curve. Fan size is defined by impeller diameter.

Pitch angleIt indicates the pitch angle of the blades. This angle is fix and should not be changed for belt driven fans, as the setting of the fan isdone by modifying ratio between driving and driven pulley.

Performance curveThis is the most representative curve of the fan. It shows the total pressure provided by the fan for a range of capacities. The point of in-tersection of the system curve and the performance curve determines the operating point of the fan. The curve doesn’t cover the entirerange from free delivery (no obstruction to flow) to no delivery, but only the useful zone of the curve where the efficiency is higher. Theselection of the fan shall assure that the operating point of the fan lies in the useful zone. A fan working out of this zone could create in-stability or overheating of the motor drive.

EfficiencyIt indicates the total efficiency of the fan represent the rate between the final energy received by the air and the energy supplied shaft ofthe fan. This efficiency reflects the losses into the fan but not the losses in the transmission and motor.

Power curvesThose curves locate in the charts standardized motors power data. To know the absorbed power of a fan working point placed betweentwo curves, interpolation may be done. For a more precise value, the next formula can be use:

W= Absorbed power in Kw Pt= total pressure in Pa, shown in the pressure axis

V= Air delivered in m3/s, shown in the capacity axis ηt = Efficiency of the fan as read in the chart in %Since this absorbed power doesn’t includes the transmission losses, so this power need to be increased by at least 15% before selec-ting the motor to be installed.

Example. The working point in the chart indicates a pressure of 420 Pa and a capacity of 8,75 m3/s. The efficiency shown is 71. The ab-sorbed power is then:

This absorbed power need to be increase by 15%, so the power to be considered for the selection of the motor would be:5,17x1,15=5,95 Kw. So a motor 5,5 Kw power won’t be enough and a 7,5 Kw should be used.

Rotational speedIt indicates the rotational speed of the impeller of the fan. Once the fan transmission has been set, this speed doesn’t vary.

Pressure AxisThe ordinate axis shows the total pressure provided by the fan. This pressure can be read both in Pa and kgf/m2 units.

Capacity AxisThe first two abscissa axis show the capacity supplied by fan. In the first one expressed in m3/s, while in the second one in m3/h. The third and fourth axis present the dynamic pressure supplied by the fan in Pa and in kgf/m2 This dynamic pressure can be obtainedusing the formula Pd=ρ v2/2, where ρ is the density and v the velocity of the fluid.Last axis indicates the velocity of the fluid at inlet and outlet of the fan. This velocity is obtained by dividing the air delivered by the sec-tion of the fan.

Safe speedStrength and mechanical properties of engineering material are affected by and change with temperature: when temperature increase,mechanical strength decrease. To avoid any damage, the running speed of the fan must stand under safe speed, according to the maxi-mum temperature predicted in the installation.

Sound pressure levelIt indicates the sound pressure at 1,5 m distance from the fan with both sides ducted, weighted considering scale A. This scale consi-ders the perception of sound by human ear. The units for sound pressure level are dBA.

Factor of inertiaIt indicates the moment of inertia of the impeller P D2. The correspondence with J is:

J in Kg • m2

W = V x Pt

J = P • D2

W = V x Pt = 8,75 x 420 = 5,17 Kw100 x ηt 10 x 71

IMPELLERS WITH ALUMINIUM HUB

The axial fans FERRARI are suitable for large quantities of air at low pressures and run very quiet.

Compared with centrifugal fans the axial fans have the following advantages:• they are cheaper;• the impeller, rotation “RD” if seen from opposite side of inlet, wich has adjustableblades, makes it possible to adapt the fan to the requirements of the plant;• reduced space requirements;• shorter ducts, therefore cheaper.Every impeller has been examined as to UNI 10531 / ISO 5801.All specifications listed in the tables are referred to air at a temperature of 15°C, specific gravity 1.226 Kgf/m3.Noise level values were taken at an average distance of 1,5 m from the fan, the decibels mentioned in the catalogue are referred to scale “A”. The readings took place in open country with outlet pipe connections (linear diagrams), with pipe connections at out -and inlet side (logarithmic diagrams).

Compared with centrifugal fans the axial fans have the following advantages:• they are cheaper;• the impeller, rotation “RD” if seen from opposite side of inlet, wich has adjustableblades, makes it possible to adapt the fan to the requirements of the plant;• reduced space requirements;• shorter ducts, therefore cheaper.Every impeller has been examined as to UNI 10531 / ISO 5801.All specifications listed in the tables are referred to air at a temperature of 15°C, specific gravity 1.226 Kgf/m3.Noise level values were taken at an average distance of 1,5 m from the fan, the decibels mentioned in the catalogue are referred to scale “A”. The readings took place in open country with outlet pipe connections (linear diagrams), with pipe connections at out -and inlet side (logarithmic diagrams).

About Ferrari

1.- General information The fans produced by F.lli Ferrari Ventilatori Industriali S.p.A. are designed and constructed for operation in severe conditions in in-dustrial environments. They are the result of over 40 years of experience in the industrial ventilation sector and a sophisticated pro-duction process with constant quality checks. The company uses technologically advanced machinery and systems to achieve thebest possible results in the manufacture of products. Exploiting its vast expertise acquired over the years, the production range cur-rently comprises 24 series of centrifugal ventilators and 12 series of axial ventilators, with rotor diameters from 180 mm to 2000mm, and high levels of component standardization have been perfected, ensuring products of prime quality.All metallic structures are designed by the company, and most are also constructed directly in its own production facility or out-sourced to exclusive suppliers of great experience that have worked with the company for many years. Both centrifugal and axialrotors are manufactured directly with the care, precision and finishing standards that have always distinguished our products. Sheetmetals and all other components received from suppliers are of excellent quality, to guarantee robust and reliable final products sui-table for the purposes they are designed to serve.

2.- Definitions and categoriesFans comply with the definitions and categories indicated by the UNI ISO 13349 standard. The dimensions of suction and deliveryflanges comply with the DIN 24154 – 24158 standards.

3.- Construction characteristicsCentrifugal impellers are made in sheet steel, with hubs in grey or nodular cast iron. The axial impellers of the series constructedentirely in aluminium are produced by die-casting and precision assembly. The axial rotors with steel cap have blades with wing pro-files made from cast aluminium and hubs in pressed sheet steel. Housings are made in flanged or welded sheet metal accordingto their intended use and overall ventilator dimensions. The cooling disks used on ventilators operating at temperatures over 60°Care made from aluminium.Production processes involving welding are carried out by workers qualified in compliance with the ASME standard, and the wel-ding processes comply with the ASME standard.The rotors are balanced to G 6.3 standards in accordance with the procedures indicated by ISO 1940-1. Paintwork is applied in amodern electrophoresis facility on all components of a suitable dimension to pass through the kilns (corresponding in size up to1250 mm). The standard painting process starts with degreasing and a light phosphate coating. After firing at 180°C, the alkyd water-based paint develops a thickness of about 40 mm. Components too large for kilns are finished with two-part vinyl epoxy paint afterthe same surface preparation. In both cases a final coating is obtained that is suitable for all climate conditions, offering good resi-stance to saline mist and resistant to temperatures up to 200°C. The standard colour is RAL 7045.For applications at higher temperatures a double coat of aluminium-based methyl silicone paint is applied, colour RAL 9006.Some products are hot-galvanized in standard versions. The treatment, applied by expert suppliers according to UNI EN ISO1461:1999 standard, gives average coating thicknesses ranging from a minimum of 55 to 85 mm, according to the thickness of steelto be galvanized.In soundproofed and insulated versions, housings have a cavity of 60 mm filled respectively with polyurethane foam or rock wool.In the first case a reduction of noise produced by the ventilator of around 3 dB with respect to standard versions is obtained. In thesecond case the filled cavity must mainly reduce heat flow and with this the external surface temperature, but an efficient sound-proofing effect is also achieved. For ventilators of medium-large dimensions with internal air temperatures of 300°C, external hou-sing surface temperatures can vary from 70 to 120°C. The corresponding values for an internal temperature of 200°C are between50 and 80°C. On request, C-type anti-sparking versions can be supplied, in compliance with the AMCA 99-0401-86 and UNI ISO13349 standards.The materials acquired for construction of the supports of our transmission ventilators are produced by major suppliers. The L10hduration of bearings has been calculated for a minimum of 20,000 hours in compliance with ISO 281/I, as long as all instructionson routine checks and lubrication indicated in product manuals are respected. All supports are supplied complete with a first fillingof lubricants.If belt transmissions are supplied, the service factor used for dimension calculations is minimum 1.5. Standard versions are fitted withV-type transmission belts with SPZ, SPA, SPB and SPC cross-sections. Belts are fitted, tensioned and aligned before shipment.

4.- SafetyFans are normally supplied for D-type installation, with ducting for inlet and outlet. Every product is complete with the shields re-quired to comply with the UNI 10615 (ISO 12499) standard for this installation category. Standard products are suitable for instal-lation with horizontal shaft. For fans acted by frequency converter is needed to know duty cycle. Sudden inversion of way of rotationis forbiden.

5.- Performance, noise emissions, vibrationsThe ventilation performance of products is determined by tests using the installation and calculation specifications indicated by theUNI 10531 standard. Using a tube of suitable dimensions for the ventilator to be tested, different airflow loads are applied by con-necting flanges calibrated at their free end. Pressure is measured in two sections of the test pipe with all the different end flanges.Air characteristics are also measured (temperature, relative humidity, barometric pressure), together with electrical data for themotor (current, voltage, power) and machine rotation speed. The test data collected are used for the calculations that provide the

ventilation characteristics of the product: flow, total and static pressure and yield. These characteristics are represented in the formof pressure-operation diagrams for transmission ventilators and charts (pressure and suction) for ventilators with direct motor drive.The data are based on an air density of 1.226 kg/m3, corresponding to 15°C and zero metres above sea level.Noise emission is measured in a free field at a distance of 1.5 metres from the ventilator and a height of 1 metre above the sup-port surface, with the ventilator ducted only on the suction or delivery side for direct-drive versions, and with ducting on both sidesfor transmission ventilators. In both cases the dimensions and minimum length of the ducts used comply with the requisites of theUNI 10531 standard for ventilation trials. The net declared sound pressure value is the arithmetical mean of seven measurementsmade around the ventilator at the distance indicated earlier, in conditions of maximum ventilation performance. The frequency bandis always measured at a point opposite the ventilator delivery aperture, or laterally with respect to the cross-section of delivery flowfor axial ventilators.Mechanical vibrations are measured on the bearings of the motor or support, in an orthogonal direction to the rotation axis and ona horizontal plane. The values normally obtained represent vibration speed expressed as a root mean square. The criteria of ac-ceptability regarding this parameter are compliant with the indications of the ISO 14694 standard.
