PRESSURE DROP ( p) CURVES 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 FILTER HOUSING PRESSURE DROP (mainly depending on the port size) considered Flow Rate and it must be lower than.4 (.3 bar)..4.6.3.4.2.3 1/2" 3/4" FSD 11-21-31 1".4.6.3.4.2.3 1 1/2" FSD 41-51-61 2 1/2" 3 1/2".1.2.1.2 13 26 4 53 66 79 53 15 159 21 263 316 CLEAN FILTER ELENT PRESSURE DROP (depending both on the internal diameter of the element and on the filter media).4.6.3.4 ESD 11.4.6.3.4 ESD 21.4.6.3.4 ESD 31.2.3.2.3.2.3.1.2.1.2.1.2 4 8 12 16 2 24 4 8 12 16 2 24 13 2 26 33 4.4.6.3.4.2.3.1.2 ESD 41.4.6.3.4.2.3.1.2 ESD 51.4.6.3.4.2.3.1.2 ESD 61 13 26 4 53 66 79 26 53 79 15 132 159 N.B.

In case of discrepancy, please check the contamination level, viscosity and features of the fluid in use.
CROSS FUNCTIONAL VIEW STRONG CONSTRUCTION The strong filter housing makes the FSD filters particularly suitable for applications where each component must provide the highest reliability. CLOGGING INDICATOR A visual or electrical indicator allows monitoring of the element condition, and gives an indication of the proper time for replacement. The port for the indicator is a standard feature. FLEXIBILITY OF ASSEMBLING A second inlet port, supplied plugged, permits you to easily solve special installation needs. NO LEAKS The end caps with captive O-ring ensure a perfect sealing between filter element and housing.
