Types of air filters

- Jan 20, 2019-

According to the principle of filtration, air filters can be divided into filtration type, centrifugal type, oil bath type and composite type. The common air filters used in engines are inertial oil bath air filters, paper dry air filters, polyurethane filter element air filters and so on. Inertial oil-bath air filters are successively filtered through three stages: inertial filter, oil-bath filter and filtering filter. The latter two kinds of air filters are mainly filtered through filter element.
