PRESSURE DROP (∆p) INFORMATION FOR FILTER SIZING

HOUSING PRESSURE DROP

FR110-11

FR130-31

The total Delta P through a filter assembly is given from Housing ∆p + Element ∆p.

The max recommended total ∆p for return filters is 0,4 – 0,6 bar with clean element.

N.B. All the reported data have been obtained at our laboratory, according to specification ISO3968 with

mineral oil having 32 cSt viscosity at 40°C and density 0,875 kg/dm

The housing ∆p is given by the curve of the considered model and port, in correspondence of the flow rate value.

FR140-43

FR150-51 FR160-64

FR1 SERIES 5/8

HYDRAULIC DIVISION FR1 SERIES

ELEMENT PRESSURE DROP

The element ∆p (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 V

different than 32 cSt a corrective factor V

/32 must be applied.

Example: 80 l/min with R130G10B and oil viscosity 46 cSt > 80 x 3,19/1000 x 46/32 = 0,36 bar

EXAMPLE OF TOTAL ∆p CALCULATION

FR130G10BBB60C000 with 80 l/min and oil 46 cSt:

Housing ∆p 0,01 bar + element ∆p 0,36 bar (80 x 3,19/1000 x 46/32) = total assembly ∆p 0,37 bar

USER TIPS

INSTALLATION

FILTER HEAD

FILTER BOWL

FILTER ELEMENT

SPRING

INDICATOR PORT

FILLING PLUG

1. the filter head (1) 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. the OUT port must be clear (an extension tube

could be fitted, if needed for having the outlet

below the oil level)

4. verify that no tension is present on the filter after

mounting

5. enough space must be available for filter

element replacement

6. the visual clogging indicator must be in a easily

viewable position

7. when a electrical indicator is used, make sure

that it is properly wired

8. 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.

When a spare spring (4) is needed please ask for,

specifying model and production batch (data given in the

identification label on the top cover)

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. unscrew the fixing bolts of the top cover and

remove it

3. remove the spring (4) first, then the dirty element

(3) and the bowl (2)

4. clean the bowl (2) and fit a new FILTREC

element (3), verifying the part number,

particularly concerning the micron rating

5. when fitting the new element (3), open its plastic

protection on the open end side and insert it

onto the spigot in the filter bowl, then remove

completely the plastic protection

6. check the top cover O-ring conditions and

replace if necessary

7. put the spring (4) in its position on the filter

element (3)

8. mount the top cover onto the head and fix it

screwing the fixing bolts

9. the used filter elements cannot be cleaned and

re-used
