Pressure drop diagrams The total Pressure Drop (Dp) value is obtained by adding the Dp 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. Housing F280-D120/24/21 PRESSURE DROP THROUGH THE FILTER HOUSING The Pressure Drop through the filter housing is governed by the port, not the bowl length and the oil viscosity. PRESSURE DROP THROUGH THE CLEAN FILTER ELEMENT Flow rate (l/min) Element D120-..-B Flow rate (gpm) The Pressure Drop through the filter element is related...

Element D143-..-A Flow rate (l/min) Flow rate (l/min) PRESSURE DROP THROUGH THE BY-PASS VALVE The by-pass valve is a safety device to prevent element collapse in case of differential pressure peaks due to flow peaks, cold start conditions or when the clogged element is not replaced in a timely manner. Flow rate (l/min) By-pass...

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 differential...
