High Pressure Filters

High Pressure Filters

High Pressure Filters are designed for operating pressures of 250 & 400 bar. High Pressure Filters at times are selected without a bypass valve to prevent contaminated oil flow into sensitive control mechanisms. In such cases, it is recommended that the filter element selected, should withstand high differential pressure. Filter elements with differential pressure ratings of 60, 160, and 330 BAR are available on request. These filters are suitable for all mineral oils, synthetic hydraulic liquids, and lubricating oils.

All filters are manufactured & tested in accordance with DIN/ISO standards.
