Air filter casings in trucks are usually placed outside the engine compartments due to its large volume. Sometimes there are two filtering cartridges. In this case the inner cartridge works as a safety device stopping contaminants from flowing into the engine during cartridge replacement or protecting from mechanical damage of main cartridge medium surface during exploitation. Due to the large size of air filter casings for trucks, they are made of steel (traditional constructions) or reinforced plastic. Placing the air inlet tangent to the outer diameter makes the casing become the filter itself using the centrifugal force resulting from the air rotational motion around the filtering cartridge.

Zbog velikih dimenzija, kućišta vazdušnih filtara za kamione obično su smeštena izvan motorskog prostora. Ponekad postoje dva uloška filtara. U ovom slučaju unutrašnji filtar deluje kao sigurnosni uređaj koji sprečava da nečistoće dospeju u motor za vreme zamene uloška, ili štiti središnji deo glavnog filtra od mehaničkih oštećenja za vreme rada. Zbog velikih dimenzija kućišta vazdušnih filtara za kamione, ova se izrađuju od čelika (tradicionalna struktura) ili od ojačane plastike. Postavljanje usisa vazduha tangentno na spoljni krug dovodi do toga da samo kućište postaje filtar koji koristi centrifugalnu silu nastalu kružnim kretanjem vazduha oko uloška za filtriranje.
