RA

The “Assembly Pressure Drop (∆p)” is obtained by adding the pressure drop values of the Filter Housing and of the Clean Filter Element corresponding to the considered Flow Rate and it must be lower than 50 kPa (0,5 bar).

PRESSURE DROP CURVES (∆p)

N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specifi c gravity 0,9 kg/dm3; for fl uids with different features, please consider the factors described in the fi rst part of this catalogue. All the curves are obtained from test done at the UFI HYDRAULIC DIVISION Laboratory, according to the specifi cation ISO 3968:2005. In case of discrepancy, please check the contamination level, viscosity and features of the fl uid in use.

FLUID SPEEDwhen selecting the fi lter size, we suggest to consider also the max recommended fl uid speed (in return lines normally 1,5 < v < 4 m/s)

BYPASS VALVE PRESSURE DROPWhen selecting the filter size, these curves must be taken into account if it is foreseen that any flow peak is to be absorbed by the bypass valve,

it also must be of proper configuration to avoid pressure peaks. The valve pressure drop is directly proportional to fluid specific gravity.
