PM P R E S S U R E F I LT E R S FLUID SPEED when selecting the filter size, we suggest to consider also the max recommended fluid speed (in pressure lines normally 5< v < 10 m/s) 400 Recommended range 350 5 < v < 10 m/s FLOW RATE [l/min] 300 250 200 150 100 50 0 1/2” 3/4” 1” PORT SIZE PRESSURE DROP CURVES (∆p) 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 considered Flow Rate and it must be lower than 120 kPa (1,2 bar). FILTER HOUSING PRESSURE DROP (mainly depending on the port...

PRESSURE FILTERS CLEAN FILTER ELEMENT PRESSURE DROP (depending both on the internal diameter of the element and on the filter media) BYPASS VALVE PRESSURE DROP When selecting the filter size, these curves must be taken into account if it is foreseen that any flow peak is to be absorbed by the bypass valve, it also must be of proper configuration to avoid pressure peaks. The valve pressure drop is directly proportional to fluid specific gravity. N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specific gravity 0,9 kg/dm3; for fluids with...

PM P R E S S U R E F I LT E R S CLOGGING INDICATOR A visual or visual-electrical differential indicator is available as an option and allows monitoring of the element conditions, giving an exact indication of the right time to replace the element. CLOGGING INDICATOR For further technical informations and other options see page 182-183. FILTER HOUSING Head and bowl are made by high performance aluminium alloy ensuring the best fatigue resistance. FILTER ELEMENT The filter element is manufactured with filter medias selected in the UFI laboratory and mechanically supported to maintain the...
