Hydraulic filter accessory MAHLE

Filter elements can only be used with optimal economy if their ability to retain contamination is fully utilized without risk. Mechanical and electronic sensors integrated in the filters or retrofitted react to continuous changes in pressure resulting from changes in the degree of contamination. These changes are then indicated via pressure gage or visual and optoelectrical switch, depending on the version used. On suction filters the negative pressure is registered, on pressure filters differential pressure, and on return-line filters banking-up pressure. This enables the operator to determine the optimal time to change the filter elements without entailing any risk.
