PRESSURE DROP (∆p) INFORMATION FOR FILTER SIZING
HOUSING PRESSURE DROP
FCR7 11-14 FCR7 20-22
The total Delta P through a filter assembly is given from Housing Δp + Element Δp .
The max recommended total Δp for return filters is 0,4 – 0,6 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.

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.
FCR7 SERIES 7/8
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: 200 l/min with R722G10 and oil viscosity 46 cSt > 200 x 0,69/1000 x 46/32 = 0,20 bar
EXAMPLE OF TOTAL ∆p CALCULATION
FCR722G10BB6BMSC000 with 200 l/min and oil 46 cSt:
Housing Δp 0,18 bar + element Δp 0,20 bar (200 x 0,69/1000 x 46/32) = total assembly Δp 0,38 bar

1. the filter head must be properly positioned and
well secured on the tank lid through the fixing
holes
2. the hose must be properly connected to the IN
port
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 from the head,
ensure that the system is switched off and there
is no residual pressure in the filter
2. remove the top cover
3. remove the spring and extract the filter assembly
4. warning : a certain quantity of oil can be
retained within the filter element, provide to
have a proper container available for it
5. unscrew the nut at the bottom of the insert and
slip the dirty filter element carefully
6. Clean the tie rod (and the magnets if present)
and check the support gaskets conditions,
replace them if necessary.
7. Fit a new FILTREC element over the tie rod
and block it by tightening the bottom nut
8. put the insert assembly into the head, put the
spring in its position over the insert support,
then mount the top cover and secure it
properly
9. the used filter elements cannot be cleaned and
re-used
