The quality inspection standards for hydraulic filter elements of wind power gearboxes are based on:
1: ISO2942 filter element structural integrity determination
2: The filtration performance of ISO16889 filter element has been tested many times
3: ISO3968 filter pressure drop flow characteristic measurement
4: Determination of the anti-rupture properties of ISO2941 filter elements
5: Determination of anti-flow fatigue characteristics of ISO3724 filter element
6: ISO2943 material and liquid compatibility determination
7: Determination of rated axial load characteristics of ISO3723 filter element
Application:
The filter has been widely used in transformer oil, turbine oil, hydraulic oil, aviation kerosene, petroleum, chemical,
power plant, coal carbon, mining, pharmaceutical, food, and engineering industries.

PRODUCT FEATURES:
1: It can filter solid pollutants with fast speed and high efficiency (βx(c) ≥1000) to better protect various control valves in the system.
2: The filter material is made of patented glass fiber and resin through a unique process. Has a fixed void structure. The fiber does not fall off. The intercepted object will not "penetrate" the filter layer due to the "pulsation" of the pressure difference and flow.
3: The filter material adopts gradually shrinking pore size structure from outside to inside along the direction of liquid flow to intercept pollutant particles of different sizes in layers to achieve deep dirt retention and greatly increase the service life.
4: Professional pleated technology production maximizes the filtration area, increases the flow processing capacity, and creates a uniform flow distribution.
5: Anti-impact fatigue filter material to improve the stability of fluid cleanliness. Improve filtration performance under harsh conditions on site.
6: Antistatic structure minimizes the generation and discharge of static charge and prevents static electricity from destroying filter elements and filter media.
7: The long service life saves costs and reduces the number of waste filter elements to be processed, which is energy-saving and environmentally friendly.
8: This product is a disposable filter element
