An air filter is a device for removing particles and impurities from the air. Piston machinery (internal combustion engine, reciprocating compressor, etc.) when working, if the inhalation of air containing dust and other impurities will increase wear parts, so must be equipped with air filters.

The air filter is composed of a filter element and a shell. The main requirements of the air filter are high filtration efficiency, low flow resistance, can be used for a long time without maintenance.

Air filters generally have paper and oil bath two kinds. Paper filter has been widely used because of its advantages of high efficiency, light quality, low cost and easy maintenance. The filtration efficiency of paper filter element is up to 99.5%, and that of oil bath filter is 95-96% under normal conditions. The air filter widely used in cars is paper filter, which is divided into dry type and wet type. For the dry filter element, once immersed in oil or water, the filtration resistance will increase sharply, so do not contact water or oil when cleaning, otherwise it must be replaced with a new piece.
