High Pressure filters Maximum pressure up to 350 bar - Flow rate up to 500 l/min Filter housing according to SAE J2066 for HF4 filter elements Mraimr- 495 High Pressure filters

FILTER SIZING Corrective factor FILTER SIZING Corrective factor The correct filter sizing have to be based on the variable pressure drop depending by the application. For example, for the return filter the pressure drop have to be in the range 0.4 - 0.6 bar. Corrective factor Y, to be used for the filter element pressure drop calculation. The values depend to the filter size and lenght and to the filter media. Reference viscosity 30 mm2/s The pressure drop calculation is performed by adding together the value of the housing with the value of the filter element. The pressure drop in the housing...
