All the curves have been obtained with mineral oil having a kinematic viscosity
30 cSt and specic gravity 0,86 kg/dm

; for uids with dierent features, please
consider the factors described in the rst part of this catalogue. All the curves
are obtained from test done at the UFI FILTERS HYDRAULICS Laboratory,
according to the specication ISO 3968. In case of discrepancy, please check the
contamination level, viscosity and features of the uid in use.
PRESSURE DROP CURVES (ΔP)
N.B.
The Pressure Drop (Δp) must be lower than 3 kPa (0,03 bar).

MAINTENANCE
The best time to change your lter element is just before it reaches
its maximum dirt-holding capacity. When it is time to change the lter
element, switch o the system before opening the tank.
Remove the dirty lter element and replace it with an original UFI
Hydraulics element, verifying the part number on the lter cap or in the
ordering and option chart. Close the tank.
N.B. The exhausted lter elements and the oil dirty lter parts are
classied “Dangerous waste material” and must be disposed of
according to the local laws, by authorized Companies.
We recommend the stocking of a spare UFI Hydraulics lter element for
timely replacement when required.
