US 2021/0260515 A1 · A DISPOSABLE AIR FILTER UNIT, AN AIR CLEANER ASSEMBLY AND AN AIR CLEANER ARRANGEMENT

Abstract

A disposable air filter unit for filtering air intake to an internal combustion engine forms a cylindrical sleeve about a central axis, and has an outer sleeve surface for receiving unfiltered air and an inner sleeve surface for output of filtered air. The disposable air filter unit includes a pleated filter component and a bioplastic reinforcement structure arranged at the pleated filter component. An air cleaner assembly includes a disposable air filter unit and a reusable carrier structure on which the air filter unit is removably arranged. The disposable air filter unit forms a sleeve about a central axis extending axially between a first end surface and a second end surface. The reusable carrier structure includes a receiving member for receiving the first end surface of the air filter unit and a sealing member arranged at the receiving member to contact the first end surface of the air filter unit.
