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) CLEAN FILTER ELEMENT PRESSURE DROP (depending both on the internal diameter of the element and on the filter media)

RD R E T U R N F I LT E R S CLOGGING INDICATOR A visual or electrical indicator is available as an option and allows monitoring of the element condition. The port for the indicator is a standard feature. STRONG CONSTRUCTION The strong filter housing makes the FRD filters particularly suitable for applications where each component must provide the highest reliability. FLEXIBILITY OF ASSEMBLING A second inlet port, supplied plugged, permits you to easily solve special installation needs. CLOGGING INDICATOR NO LEAKS The end caps with captive O-ring ensure a perfect sealing between filter element...
