Pressure drop diagrams The total Pressure Drop (Ap) value is obtained by adding the Ap values of filter housing and filter element at the given flow rate. This ideally should not exceed 1,0 bar (14,5 psi) and should never exceed 1/3 of the set value of the by-pass valve. PRESSURE DROP THROUGH The Pressure Drop through the filter housing is governed by the port, not the bowl length and the oil PRESSURE DROP THROUGH THE CLEAN FILTER ELEMENT The Pressure Drop through the filter element is related both to the internal diameter of the filter element and to the filter media; this value is...

Clogging indicator The Pressure Drop (Dp) through the filter increases during the system operation due to the contaminant retained by the filter element. The filter element must be replaced when the indicator shows an alarm and before the Dp reaches the by-pass value setting. N.B. in cold start conditions a false alarm can be caused by higher oil viscosity due to low temperature; the indicator alarm must be considered at normal working temperature only. The differential clogging indicator registers the pressure upstream and downstream the filter element and activates a signal when the...
