QF7301W25HP0.7C is an efficient and precise filter element designed specifically for dual filters. With military grade manufacturing processes and excellent filtration performance, it has become the core protective component in oil purification systems and is widely compatible with gas turbine engine oil power systems, generator set cooling water systems, and various general industrial hydraulic systems, providing solid support for stable operation of equipment in multiple industries. As the exclusive filter element of the dual filter, it is perfectly compatible with the parallel structure of the dual cylinder, which can achieve non-stop switching and replacement, ensuring the continuity of filtration work and greatly reducing the risk of production interruption, while also considering the convenience of operation and maintenance and production efficiency.

In terms of core structure and material configuration, the filter element adopts a folding design, using high-quality glass fiber as the core material of the filter layer, matched with a fully stainless steel skeleton, which combines acid and alkali resistance, high temperature resistance, and extremely strong structural stability. The folding structure greatly expands the effective filtration area, reaching 0.8 to 1.0 square meters. While increasing the pollutant holding capacity, it effectively reduces the resistance of oil passing through and ensures smooth circulation. Its filtration accuracy is precisely controlled within 5 to 10 μ m, which can efficiently intercept particle impurities, suspended solids, and colloidal precipitates in oil or stator cooling water, avoiding impurities from wearing core components such as hydraulic pumps, valve groups, and hydraulic motors. At the same time, it prevents pipeline blockage and stator winding overheating damage, helping to improve the insulation performance and equipment service life of the unit.

This filter element has excellent adaptability to working conditions, with a maximum working temperature of up to 150 ℃. It can withstand high-pressure environments and adapt to different working conditions with the maximum working pressure difference. It can operate stably in complex and demanding work scenarios such as chemical, metallurgical, and engineering machinery. The inlet and outlet diameter specifications are compatible with mainstream dual filter interfaces, which are easy to install and have excellent sealing performance. They can directly adapt to key parts such as the outlet of the chilled water pump and the return oil pipeline of the hydraulic system. Whether as an impurity filtration barrier for fuel engine systems, a purification core for generator set cooling water systems, or a protective component for general hydraulic systems, the QF7301W25HP0.7C filter element achieves the dual goals of oil cleanliness control and equipment protection with its advantages of precise filtration, stability, durability, and strong universality. It is the preferred component for upgrading and operating dual filtration systems in the industrial field.
