STAUFF pressure filters have a range of contamination indicators available as an option. If no indicator is specified, the port is sealedby a plug (HI-O). The contamination indicators are actuated by the differential pressure (∆p) across the element and the specialpiston design minimizes the effects of peak pressures in the system. An optional thermostatic lockout (thermo-stop) is available toprevent false indication under cold start conditions. Fluid temperature must be at least 68°F (20°C) for the indicator to function.

Visual contamination indicators are available in the following configurations:

Manual reset The indicator continues to display con-tamination even through the ∆p mayhave fallen. Pressing the plastic coverdown will reset the indicator.

Automatic reset The contamination signal will disappearwhen the ∆p drops below the setting for the indicator.

Note: Electrical and Visual-Electrical contaminationindicators are only available with automatic reset.

TECHNICAL SPECIFICATION

Note: High voltage peaks occurwhen inductive loads are switchedoff. Protective circuitry should beemployed to reduce contact burnout.

TECHNICAL DATASTAUFF RF return line filters are designed as tank top filters. They are mounted directly on the tank top andif 100% of the system oil is filtered, they provide the optimum removal of contaminant from the system.This provides the pump with clean oil thus reducing contaminant generated wear. The filter bowl is designedto return oil beneath the tank oil surface thus preventing the entrainment of air by the returning oil.

TECHNICAL SPECIFICATIONS/OPTIONS

Construction – Tank Top flange mounting

Filter head – Aluminum

Filter bowl – Steel

Seals – NBR Buna-N, FPM (Viton) or EPDM (Ethylene-Propylene)

Threaded – NPT- and connection – SAE-“O“-Ring thread

– SAE-flange (3000 psi)

Max. Operating press. – 230 psi (16 bar)

Proof pressure – 350 psi (24 bar)

Temperature Range – -10°C up to +100°C14°F to 212°

Bypass valve – Opening pressure (integrated in the 43 psi ± 4 psi (3 bar ± 0.3 bar) filter element) – Other pressures available on request

Contamination – Gauge indicator 0-58 psi indicator (0-4 bar) with colored segments

– Electrical switch, setting 36 psi (2.5 bar)

Filter elements – Filter material specification A, B, G, S:Collapse rating per ISO 2941 430 psi (30 bar) ∆p

– Filter material specification D, N:Collapse rating per ISO 2941 230 psi (16 bar) ∆p

Media – Mineral oils – Other fluids on request

OPTIONS1. Visual contamination indicator

The gauge displays the degree of contamination of the element. The coloredsegments allow quick visual checking.green 0 -36 psi (0.0-2.5 bar) Element has service life leftyellow 36-43 psi (2.5-3.0 bar) Element is contaminated and

should be changed red >43 psi (>3.0 bar) Bypass valve open, unfiltered oil

passing to tankThe contamination indicator can be mounted on the top or on the side of the filter head (see drawing on page 96).

2. Electrical contamination switch

The switch is used where an electrical signal is needed to indicatewhen the element needs changing. The switch can turn on a light,or shut the machine down, or any other function controlled by anelectric signal. The switching pressure is 36 psi (2.5 bar) and this allows the element to be changed before the bypass setting of 43 psi (3.0 bar) is reached.

Maximum Voltage Switch Type24 V G 24V

110 V G 110220 V G 220

3. Leakage oil connection

Seal or case drain lines can be connected to the filter througheither of the contamination indicator ports providing that the leakage oil can accept a pressure of 43 psi (3.0 bar.) It ensures that no un-filtered oil returns to the reservoir.

4. Filter bowl with threaded connection

Under some circumstances such as a tall reservoir or one withoil levels which vary greatly during operation, it is necessary toextend the filter bowl so that the returning oil returns beneath thesurface and no air enters during the process. The optional bowlwith a female thread allows an extension to be fitted quite simply.

Multi Pass Testing (Beta Ratio)The Beta Ratio (βx) is considered one of the most important criteria in assessing the capability of a filter to removecontaminant particles. This value is determined by means of the multi-pass test, according to ISO/DIN 4572.

Definition: The Beta Ratio is the ratio of the number of particles, greater than a given size, upstream of the filter to the number of particles, greater than the same size, downstream of the filter in the same sizefluid sample.

βx = Number of particles >xµm upstream (x = particle size)

Number of particles >xµm downstream

The Beta Ratio can be used to calculate the Filter Efficiency Rating by the following formula.

Ex = βx - 1 x 100 Ex = % efficiencyβx

Example for a given particle size of 10 µm

β10 = 9360 = 208 E10 = 208 - 1 x 100 = 99.52 %

Choice of the optimum filter

In selecting the filter, the following informationmust be considered:

• maximum flow volume (Qmax) through the filterincluding surge flows

• kinematic viscosity (υ) of the fluid in SSUat cold start temperature and operatingtemperature

• micron rating (µm): see table

• filter material

The aim is to choose a filter whose totaldifferential pressure (∆p) is no greater than∆pmax = 14.5 psi (1.0 bar) for pressure filters or∆pmax = 7.5 psi (0.5 bar) for return line filters, in aclean state at the normal operating temperature.These values have been proven in practice to givethe optimum service life for the element.

The nominal flow volume of the filter is theobvious reference value for pre-selection and thisshould be larger than the flow to be filtered.

Qnom > Qmax

Calculations based on the filter data will verifywhether the pre-selected filter meets therequirements, at operating temperatures:

∆pmax < 14.5 psi (1.0 bar) (for pressure filter)∆pmax < 7 psi (0.5 bar) (for return line filter)

The total differential pressure is the sum of thedifferential pressure values of the empty housingand the filter element. They are calculated fromthe flow characteristics tables.

∆ptotal = ∆phous + ∆pelem

The flow characteristic tables are based on akinematic viscosity of 30 centistokes (141 SSU).For different viscosities, a correction factor (K)based on the following formula must be appliedto the figure calculated at 30 centistokes (141 SSU).

υ + υ141 141K =

2

The operating differential pressure is thencalculated by the following formula:

∆poperating = ∆pnom + K x ∆pelem

The filter size is suitable if the ∆poperating < ∆pmax.If the calculated ∆poperating is greater than ∆pmax,select the next larger filter size and re-calculateuntil a satisfactory solution is found.

The following two examples explain the procedure.

CHOICE OF FILTERS

Choice of a suitable micron rating

Generally, the type of components incorporated inthe hydraulic system will determine the micronrating required. It has been clearly demonstratedthat system components will operate reliably foryears if a specific minimum oil cleanlinessgrade is maintained. Frequently the choice will bedetermined by the most sensitive componentin the system.

a) Operating filter

The following chart is a general guide but the finalresult should be checked by oil analysis. Apart fromthe specific flow rate (gpm/in2 of filter area), otherfactors such as operating environment andcondition of seals and breathers can have an effecton the cleanliness grade which can actually beachieved.

Oil cleanliness Microngrade as per rating Area of ApplicationISO 4406

13/10 3 µm servo valve hydraulics16/13 5 µm proportional hydraulics18/15 10 µm standard hydraulics >100 bar19/16 20 µm standard hydraulics <100 bar

b) Protective filter

Occasionally, protective filters are fitteddownstream of major components, eg., the pump,to collect the debris in case of a catastrophicfailure. This avoids total stripping and flushing ofthe system. For economic reasons, protective filtersare normally one grade coarser than the operatingfilters since they do not significantly contribute tothe cleaning of the system and this extends filterservice intervals.

Example 1: Selection of a pressure filterSystem Information. A pressure filter with an inorganic glass fiber element is required immediately afterthe pump. The system has standard components and is operating at pressures up to 3000 PSI (200 bar).The filter shall be fitted with a bypass valve and a visual contamination indicator.Data given: Qmax = 45 gpm (170 lpm)

υoperating = 213 SSU (46 cSt)Micron rating 10 µm (see table on page 8&9)

First StepPre-selection: Size SF 070, Qnominal = 70 gpm > Qmax

Pressure drop values at viscosity of 141 SSU (30 cSt) from the flow characteristics:∆phous – = 3.6 psi (0.25 bar) (SF 070 –, see page 7)∆pelem – = 12 psi (0.8 bar) (SE 070 G 10 B, see page 9)

Determination of the correction factor (see page 9)centistokes 46 + 46 213 + 213

K =30 30 = 1.39 K =

141 141 = 1.39

2 2Determination of the actual pressure drop:

∆pactual= ∆phous + K · ∆pelem = 0.25 bar + 1.39 x 0.80 bar = 1.36 bar > ∆pmax = 1.0 bar3.62 psi + 1.39 x 11.6 psi = 19.7 psi > ∆pmax = 14.5 psi

Since the actual pressure drop is larger than the allowed pressure drop, a larger filter has to be chosen.Second StepSelection of the next larger filter size; SF 090, Qnominal = 90 gpm > Qmax

∆phous = 2.1 psi (0.15 bar) (SF 090 –, see page 7)∆pelem = 8.7 psi (0.6 bar) (SE 090 G 10 B, see page 9)

Actual pressure drop ∆pact = ∆phous + K · ∆pelem = 0.15 bar + 1.39 x 0.6 bar = 0.99 bar ≤ ∆pmax = 1.0 baror = 2.1 psi + 1.39 x 8.1 psi = 13.4 psi ≤ ∆pmax = 14.5 psi

In a clean state, this filter fulfills the requirements and is suitable for the application.The correct filter designation is: SF090G10BTB/BV

System Information. A return line filter with a paper element is required to clean the oil. No contamination indicator is required.N. B. If the system incorporates either accumulators or cylinders, the return flow can

dramatically exceed pump flow and the maximum surge flow should be the flow used to calculate the pressure drop through the filter.

Data given: Qmax = 24 gpm (90 lpm)υoperating = 150 SSU (32 cSt)Micron rating 20 µm (see table page 14)

First StepPre-selection: Size RF 030, Qnominal = 30 gpm > Qmax (29 gpm)Pressure drop values at viscosity of 141 SSU (30 cSt) from the flow characteristics:

∆phous = 4 psi (0.27 bar) (RF 030 –, page 14)∆pelem = 0.6 psi (0.04 bar) (RE 030 N 20 B, page 14)

Determination of the correction factor (see page 14)centistokes 32 + 32 150 + 150

K = 30 30 = 1.05 K = 141 141 = 1.052 2

Determination of the actual pressure drop:∆pactual = ∆phous + K · ∆pelem = 0.27 bar + 1.05 x 0.04 bar = 0.31 bar < ∆pmax = 0.5 bar

or = 4 psi + 1.05 x 0.6 psi = 4.6 psi ≤ ∆pmax = 7.5 psiIn a clean state, this filter fulfills the requirements and is suitable for the application. No furthercalculation is necessary.The correct filter designation is: RF030N20B/B
