Abstract: An apparatus and a method are provided for an air filter configured to be mounted onto air inlets of turbochargers and superchargers. The air filter a proximal base including an inlet receiver configured to receive an air inlet, a clamp to secure the air inlet within the inlet receiver, and a first opening aligned with a screw mechanism of the clamp. A filter medium fastened to the proximal base is configured to remove particulate matter and other contaminates from an incoming air stream. A distal end cap fastened to the filter medium comprises a second opening aligned with the first opening. A conduit within an interior cavity of the air filter is disposed between the first opening and the second opening, facilitating tightening and loosening the clamp by extending an appropriate tool through the interior cavity so as to engage the screw mechanism of the clamp.

Abstract: An air filtration system comprises a filter housing that defines a collection chamber and includes an air inlet, an air outlet and a cleaning assembly opening in fluid communication with the collection chamber. The system also comprises a filter support mounted to the filter housing with each one of the air inlet and the air outlet being located on a respective side of the filter support; and a filter cleaning assembly mounted to the filter housing and including an actuation system; and a diaphragm assembly at least partially covering the filter cleaning opening. The diaphragm assembly vibrates upon actuation of the actuation system so as to displace air in the collection chamber to remove particulate matter from a filter engaged with the filter support. The present disclosure also concerns a combustion engine comprising an air filtration system and a method for cleaning an air filtration system.

Abstract: A filter housing for a filter system for gaseous fluid has a housing wall with an inlet opening for a fluid to be filtered and an outlet opening for filtered fluid arranged in the housing wall. A receiving space inside the housing wall is provided for a filter element separating a raw side from a clean side between inlet and outlet openings upon intended mounting in the filter housing. An inflow guard is arranged at a housing segment provided with the inlet opening. The inflow guard is spaced radially from the housing segment and directed toward the receiving space. The inflow guard extends substantially only across the inlet opening. A filter system with such a filter housing has a purging device for intermittently emitting purging medium pressure surges from a clean side of the filter element arranged in the receiving space to a raw side of the filter element.

Abstract: An air cleaner is adapted to be mounted inside of a cabin of a mass transit vehicle to remove or disinfect pathogens in the air. The air cleaner includes a housing, an air filter, a grill, and optionally a disinfector. The housing is formed to define an air chamber, an inlet into the air chamber, and an outlet out of the air chamber. A fan draws air through the air chamber during use of the air cleaner. The air filter is received in the air chamber and the grill covers the air filter to secure the air filter between the grill and the housing and allow air to flow through the grill and filter into the air chamber.

Abstract: A filtration system includes an air cleaner housing and a filter element. The air cleaner housing includes a base and a removable cover. At least one of the base or the cover defines a cavity and a protrusion extending into the cavity. The filter element is disposed within the cavity. The filter element includes a plurality of media blocks each including a pleated filter media. The plurality of media blocks are arranged in arch shapes of approximately equal inner radii. The plurality of media blocks are coupled to each other along opposing edges that extend along a pleat direction of the pleated filter media. The media blocks together define at least one void that extends along the protrusion. The protrusion occupies a portion of the void.
