The filter installed in the hydraulic system of the Department return lines, to filter out the oil in the various components and wear metal particles and the rubber seals wear impurities, so that the oil flow back into the tank clean, beneficial to the system oil recycling.

The filter sub-fiber, paper, mesh and wire Clearance four kinds of filters. Fiber filter paper filter than filter effects, high precision, chemical filters and paper filters to clean filter more difficult to plug, it is necessary to replace the filter.

The filter cartridge with fiber filter material, with high precision filter,  the high oil capacity, the small original pressure loss, the large accommodate pollutant load and other advantages, the filtration precision of absolute precision for filter, filter β3, β5, β10, β20 ≥ 200, filtration efficiency η ≥ 99.5%, evaluation method for the ISO16889-99, and GB/T18853-2002.
