RETURN FILTERS FLUID SPEED when selecting the filter size, we suggest to consider also the max recommended fluid speed (in return lines normally 1,5 < v < 4 m/s) PRESSURE DROP CURVES (Ap) The "Assembly Pressure Drop (Ap)" 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). FILTER HOUSING PRESSURE DROP (mainly depending on the port size) N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specific gravity 0,9...
