Air filter is a filter, also known as air filter cartridge, air filter, style and so on.
Mainly used in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and a variety of precision operating rooms in the air filtration. The engine absorbs a lot of air during the working process, and if the air is not filtered, the suspended dust in the air is inhaled into the cylinder, which accelerates the wear of the piston group and cylinder. Larger particles enter between the piston and the cylinder, which can cause serious "pull cylinder" phenomenon, which is particularly serious in dry and sandy working environment. The air filter is mounted in front of the carburetor or inlet pipe to filter out dust and sand particles in the air, ensuring that the cylinder enters a sufficient amount of clean air.
