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 F420-D11... 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. Flow rate (l/min) Element D110-..-B Flow rate (gpm) The Pressure Drop through the filter element is related both to the internal diameter of the filter...

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. Flow rate (l/min) 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 effected by the oil viscosity in a roughly proportional way: e.g. when the Dp value from the curve is 0,2 bar and a 46 cSt oil is used, the corresponding value is 0,31 (=0,2 : 30 x 46) bar. PRESSURE DROP THROUGH THE CLEAN FILTER...

Filter Elements The F420 series is usually equipped with filter elements according to a widely accepted (US based) industry standard, having the dimensions listed here below. Alternative version The F420 series can be optionally equipped with filter elements according to a different standard (European based), having the dimensions listed here below. Their performances are corresponding to the standard version as indicated in the table, where you can see also the different filter housing lengths if applicable. Housing dimensions except *H1 see see see see see see see

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...
