Pressure pipeline filters can be installed on pressure pipelines of different pressure levels to further remove or block impurities caused by the wear and tear of components brought in from the outside and the chemical effects of the medium itself. Especially suitable for automatic control systems and servo systems. It prevents high-precision control components and actuators from premature wear or jamming due to contamination, thereby reducing failures and extending component service life. This filter uses imported glass fiber filter material, which has the advantages of high filtration precision, strong oil passing capacity, small original pressure loss, and large dirt holding capacity.
