Dry air filter is through a dry filter element, (such as paper filter) will be separated from the air impurities filter. Light vehicles (including cars, micro cars) used in the air filter is generally a single stage. It has a flat or oval shape and flat type. The filter material is filter paper or non-woven fabric. The end caps of the filter element are metal or polyurethane, and the housing material is metal or plastic. Under the rated air volume flow rate, the original filtration efficiency of the filter element should be not less than 99.5%. Heavy-duty vehicles have to have most of its air filters due to the harsh working environment. The first stage is a cyclonic pre-filter (such as vane ring, cyclonic tube, etc.), which is used to filter out coarse and large particles of impurities with a filtration efficiency of more than 80%. The second stage of fine filtration is a microporous paper filter element (generally called the main filter element), which has a filtration efficiency of more than 99.5%. After the main cartridge, there is a safety cartridge, whose role is to prevent dust from entering the engine when the main cartridge is installed and replaced, or when the main cartridge is damaged by chance. The material of the safety core is mostly non-woven fabric, and filter paper is also used.
