The hydraulic filter element is used in the hydraulic system to filter out particle debris and rubber impurities in the system to ensure the cleanliness of the hydraulic system. The industrial hydraulic oil filter element adopts filter materials imported from foreign original factories. It is a double-layer microfiber structure. The outer coarse fiber is gradually loosened from the inside out. It can reduce the differential pressure of the filter element, and the scale of the filter element can be increased and the service life is extended. Our factory has all kinds of production equipment and testing equipment, all kinds of technicians and management personnel, and a perfect product quality management system.
