Abstract: An assembly and system of an air cleaner for a vehicle is described herein. The air cleaner assembly and systems include a filter cartridge extending along a longitudinal axis between a first filter end and a second filter end. The filter cartridge includes filter media configured to filter air passing through the filter media. The filter cartridge includes a cartridge passage defined by an inner filter surface of the filter cartridge. The air cleaner assembly and systems also include a pulse tube extension coupled to the filter cartridge and extending into the cartridge passage along the longitudinal axis such that an outer tube surface of the pulse tube extension faces the inner filter surface of the filter cartridge. The pulse tube extension defines a tube passage located within the cartridge passage.

Abstract: Principles, techniques and configurations applicable in air cleaner arrangements and filter cartridges therefore, are described. In general the filter cartridge includes an axial pivot arrangement, for pivoting the filter cartridge in place, when mounted in an air cleaner for use. The air cleaner may include a base pivot, for engagement with the pivot projection on the filter cartridge. Methods of assembly, installation and use are described.

Abstract: An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.
