PRESSURE DROP (∆p) INFORMATION FOR FILTER SIZING
HOUSING PRESSURE DROP
FS7 41
The total Delta P through a filter assembly is given from Housing Δp + Element Δp.
The max recommended total Δp for suction filters is 0,15 bar with clean element.
The housing ∆p is given by the curve of the considered model and port, in correspondence of the flow rate value.
ELEMENT PRESSURE DROP 
The element Δp (bar) is given by the flow rate (l/min) multiplied by the factor in the table here below
corresponding to the selected media and divided by 1000.
If the oil has a viscosity V1different than 32 cSt a corrective factor V1/32 must be applied.
Example: 80 l/min with S741T60 and oil viscosity 46 cSt > 80 x 0,075/1000 x 46/32 = 0,09 bar
EXAMPLE OF TOTAL ∆p CALCULATION
FS741T60BB7BMPPSD with 80 l/min and oil 46 cSt
Housing Δp 0,02 bar + element Dp 0,09 bar (80 x 0,075/1000 x 46/32) = total assembly Δp 0,11 bar

N.B. All the reported data have been obtained at our laboratory, according to specification ISO3968 with mineral oil
having 32 cSt viscosity and density 0,875 Kg/dm3.
BYPASS VALVE PRESSURE DROP
The bypass valve ∆p is given by the curve of the considered model and setting, in correspondence of the flow rate
value.

9 INDICATOR PORT
1. the filter housing (2) must be properly
positioned and well secured on the tank side
wall through the fixing holes
2. the OUT port must be properly connected to
the suction line
3. verify that no tension is present on the filter after
mounting
4. enough space must be available for filter
element replacement
5. the visual clogging indicator must be in a easily
viewable position
6. when a electrical indicator is used, make sure
that it is properly wired
7. keep in stock a spare FILTREC filter element for
timely replacement when required
OPERATION
1. the filter must work within the operating
conditions of pressure, temperature and
compatibility given in the first page of this data
sheet
2. the filter element must be replaced as soon as
the clogging indicator signals at working
temperature
3. If no clogging indicator is mounted, replace the
element according to the system manufacturer’s
recommendations
WARNING
Make sure that Personal Protective Equipment (PPE) is
worn during installation and maintenance operation. 
DISPOSAL OF FILTER ELEMENT
The used filter elements and the filter parts dirty of oil
are classified as “Dangerous waste material”: they
must be disposed according to the local laws by
authorized Companies.
MAINTENANCE
1. before removing the top cover (1) from the
housing (2), ensure that the system is switched
off and there is no residual pressure in the filter
2. unscrew the cover (1) by turning it anticlockwise
3. remove the dirty element (5) by pulling it
carefully
4. fit a new FILTREC element(5), verifying the
part number, particularly concerning the micron
rating
6. check the seal (4) conditions and replace if
necessary
7. lubricate the threads and screw completely the
cover (1) in the filter housing by turning it
clockwise
8. the used filter elements cannot be cleaned and
re-used
