1. Filtering impurities: Hydraulic oil filter can filter out solid particles, gelatinous substances, and various impurities mixed from the outside or generated internally during system operation in the working medium. These impurities may include dust, metal shavings, rubber debris, etc., which can cause wear and corrosion to hydraulic system components such as valves, pumps, cylinders, etc., and even lead to system failures. The filtering effect of the hydraulic oil filter element can effectively protect the internal components of the system and extend their service life.

2. Remove moisture: Hydraulic systems may contain moisture due to environmental humidity or other factors, which can seriously affect the lubrication of hydraulic oil, corrode internal components, and may produce bubbles that affect system performance. The filter material in the hydraulic oil filter element has water absorption performance, which can remove moisture from the oil and maintain its dryness and cleanliness.

Maintain oil cleanliness: Hydraulic oil filter can filter out solid particles, gum, and asphalt substances in the oil, maintaining the cleanliness and stability of the oil quality. This is crucial for the normal operation of hydraulic systems, as the cleanliness of the oil directly affects the performance and lifespan of the system.
