Air filter is a kind of filter, also called air filter, air filter, style and so on. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operating rooms and various precision operating rooms.
   

The engine will swallow a lot of air in the working process, if the air is filtered, suspended in the air dust to be sucked into the cylinder, piston and cylinder will accelerate the wear. Between larger particles into the piston and the cylinder, will cause serious scuffing, which is particularly serious in dry sandy environment. The air filter is installed at the front of the carburetor or intake pipe, which plays the role of removing dust and sand particles in the air, ensuring that the cylinder enters sufficient and clean air.
