Abstract: A pulse ring assembly for air cleaner systems that is adapted to produce a pulse ring of gas to clean a filter element. The air cleaner system may include an outer tube and an inner tube configured to receive the inner tube such that at least a portion of an interior surface of the outer tube faces at least a portion of an exterior surface of the inner tube. The outer tube may include a pulse port extending between the interior and exterior surfaces of the outer tube into an outer tube passageway. Filtered air may be configured to flow from a first filter cartridge, through the outer and inner tubes, and to an engine intake. The system may also include a pulse jet apparatus in fluid communication with the pulse port of the outer tube and configured to direct gas through the pulse port towards the first filter cartridge.

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: A system and method of operating an air cleaner assembly including a selective scavenging apparatus that may be configured to actuate in response to a pulse cleaning operation. The air cleaner assembly may include an air cleaner housing, filter media positioned within an interior space of the air cleaner housing, a pulse cleaning apparatus extending into the interior space, and the selective scavenging apparatus in fluid communication with an egress aperture of the air cleaner housing. The selective scavenging apparatus may be configured to move fluid and sediment out of the air cleaner housing during a scavenging time period and the pulse cleaning apparatus may be configured to direct a pulse of gas into the clean air space during a cleaning operation. The scavenging time period may start based on the beginning of the cleaning operation and may end based on the completion of the cleaning operation.
