This hydraulic return oil filter element is specifically designed for hydraulic systems in construction machinery. It features an integrated, convenient handle for easy installation, removal, and maintenance. The filter element utilizes a high-strength perforated metal shell and high-precision glass fiber filter media, effectively filtering metal debris, dust, and rubber particles from hydraulic oil with a filtration accuracy of 10-25μm. Its large surface area design ensures high dirt-holding capacity, reducing maintenance frequency and extending service life. A built-in bypass valve automatically opens when the filter element becomes clogged, preventing dry running of the hydraulic system. This filter element is suitable for excavators, loaders, cranes, and other heavy equipment, effectively protecting hydraulic pumps, valves, and cylinders, ensuring stable operation of the hydraulic system under harsh conditions.
