Abstract: A filter element includes a construction of pleated filter media defining an interior volume. First and second opposite end caps are secured to opposite ends of the filter media. A support structure supports the filter media and is operably oriented in the interior volume. The support structure extends from the first opposing interior face to the second opposing interior face. The support structure is provided to extend less than a full extension between the first end cap and second end cap.

Abstract: Filtration media, media packs, and filtration elements are described, including fluted filtration media having offset flutes arranged to intermittently contact flutes on adjacent media, including angled and curved flutes. Pleated filtration media with alternating sealed pleat edges are also disclosed, including fluted media with alternating sealed flutes. A media pack can have a first sheet of media and a second sheet of media. The first sheet of media can have a first plurality flutes defining first flute valleys extending between a first face and a second face of the media pack. The second sheet of media can have a second plurality of flutes defining second flute peaks extending between the first face and the second face of the media pack. The first plurality of flutes can be non-parallel to the second plurality of flutes, and each first flute valley contacts one second flute peak at a discrete contact point.

Abstract: An air cleaner assembly includes a precleaner assembly. In one aspect, the precleaner assembly incudes a bypass arrangement that is operated to bypass a portion of air around the precleaner assembly. The bypass arrangement can be operated by a controller based on at least one input signal corresponding to one or more of a vehicle speed, a vehicle engine speed, a vehicle engine load, an operator input, a vehicle location, an air pressure drop across a filter element, an air pressure drop across the precleaner assembly, an acoustic level, a vibration level, a change or cleaning frequency of the filter element, a total number of filter element changes, an identity of the filter element, an identity of the engine, an identity of the vehicle, an air flow rate through the precleaner assembly or through the filter element, and a weather condition parameter identified through data received locally or from a weather service.

Abstract: An air filter element includes a filter arrangement, an elbow, and a filter element seal member. The filter arrangement includes a filter media pack having a dirty air inlet and a clean air outlet, wherein air flowing through the clean air outlet flows in a first axial direction and the clean air outlet defines a filter arrangement cross sectional area. The elbow has a first end constructed to extend from the filter arrangement clean air outlet, a second end wherein air flowing through the second end flows in a second axial direction, and an air flow enclosure extending from the elbow first end to the elbow second end. The air flow enclosure includes an air deflector constructed to direct air from the first axial direction to the second axial direction, wherein the second axial direction is different from the first axial direction, and an interior volume between the elbow first end and the elbow second end. The filter element seal member is located on the elbow second end, wherein the filter element seal member is constructed to seal to a clean air intake, the filter element seal member located on the elbow second end defining a seal member cross sectional area. The filter element can be characterized as having a ratio of the seal member cross sectional area to the filter arrangement cross sectional area of at least 0.5. The filter element can have a z-filter media pack for a pleated media pack. The air filter element can be arranged in an air cleaner.

Abstract: An air cleaner assembly with a restriction indicator includes a housing having an exterior surface around an interior volume. The housing includes a bore extending through a portion of the exterior surface of the housing surrounded by a bore wall protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel between the bore wall and the receptacle wall. A restriction indicator measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.
