Air filter refers to a device for removing particulate impurities in the air

Air filter refers to a device for removing particulate impurities in the air. Piston (internal combustion engine, air filter, etc.), if the inhaled air contains dust and other impurities, it will aggravate the wear of parts, so air filter must be equipped. The air filter consists of two parts: filter element and housing. The main requirements of air filtration are high filtration efficiency, low flow resistance, and continuous use without maintenance.

There are three ways: inertia, filtration and oil bath.

①Inertia: because the density of impurities is greater than that of air, when impurities rotate or rotate sharply with air, centrifugal inertia can separate impurities from the air flow.

②Filtre : guider l'air à travers un filtre métallique ou un papier filtre, bloquer les impuretés et adhérer à l'élément filtrant.

③Type à bain d'huile : il y a un bac à huile organique au bas du filtre à air. Le flux d'air est utilisé pour impacter rapidement l'huile, séparer les impuretés et coller à l'huile. L'élément filtrant essentiel du flux d'air peut en outre absorber les impuretés pour atteindre l'objectif de filtration.
