FLUID SPEED when selecting the filter size, we suggest to consider also the max recommended fluid speed (in off-lines normally 1,5 < v < 4 m/s) Recommended range FLOW RATE [l/min] PORT SIZE PRESSURE DROP CURVES (∆p) 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). 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...

O F F - L I N E F I LT E R S CLEAN FILTER ELEMENT PRESSURE DROP WITH F+, C+ AND ME MEDIA (depending both on the internal diameter of the element and on the filter media) BYPASS VALVE PRESSURE DROP When 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. N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specific...

CLOGGING INDICATOR A differential clogging indicator allows monitoring filter element and provides the exact time for replace the element. BYPASS VALVE The bypass function is obtained by the filter element moving axially, in such a way that the contaminant is retained in the filter element during bypass. FILTER ELEMENT “LONG LIFE” Filter elements are manufactured with a large surface area, in order to ensure a high dirt holding capacity. Inside to outside filtration ensures the contaminant is retained inside the element during replacement. FLEXIBILITY OF INSTALLATION Outlet port should be...
