Shell, cover plate and other metal parts are made of high-quality steel with high dimension accuracy and better performance, which improves the static pressure rupture resistance of products and ensures normal operation in extreme environments.

High quality and precision filter paper, high filtration efficiency, long service life; The filter paper after special processing has higher oil resistance performance, reducing the damage resistance loss of filter paper under high oil temperature, which can meet the normal use in different environments.

The threaded cover plate and sealing plate are welded with if inverter dc to ensure the welding position is firm and reliable.

The computer simulation is adopted to further optimize the check valve structure design to prevent oil reflux inside the oil filter when the engine stops working, so as to ensure timely oil supply and lubrication of the engine lubrication system when the vehicle restarts.

The sealing original parts made of high performance materials are selected and tested under the environment of -40℃+135℃, which can ensure the normal use of the filter under the environment and make the performance more reliable.

Shell surface adopts electrostatic spraying technology, the surface coating adhesion is strong, the shell is not easy to rust, the internal cleanliness is high, and in line with the national environmental protection requirements.

The edge of the filter element frame material is strong, reasonable thickness and adhesion is very firm and reliable. It can effectively ensure that the product is not deformed in use, good sealing.

The filter element is made of composite material, and the surface is made of glass fiber with electrostatic adsorption function. It can effectively absorb dust, impurities, particles and carbides in the air.

Activated carbon and fiberglass composite is used for filter media. Using the advanced laminating process, to ensure good ventilation rate of product, activated carbon with bamboo carbon can effectively remove soot, ozone, bad breath, carbon oxide, pollen, SO2, CO1, sterilization deodorization function at the same time, to ensure driving room air is fresh and not breed bacteria, create a good safe and healthy environment.
