An air cleaner housing can include a main body including an end wall defining a first axial opening with a first diameter; a cover removably secured to the main body such that the cover and main body cooperatively define an interior volume; and an outlet assembly secured to the main body at the location of the first axial opening and including: a first part having a first radial flange located on an interior side of the main body end wall and having a first circumferential wall structure, the first part defining a radial sealing surface for a filter cartridge; a second part coupled to the first part, the second part having a second radial flange located on an exterior side of the main body end wall and having a second circumferential wall structure, the second part defining an air inlet or outlet opening. The first and second circumferential wall structures are permanently joined together at a circumferential weld joint such that the main body end wall is between the first radial flange and the second radial flange and such that the outlet assembly is rotatable with respect to the main body.

Air cleaner and filtration assemblies

A filter cartridge can include a media pack including media extending between a first end and a second end along a longitudinal axis; an end cap secured to the media and including: a seal member presenting a radially inward or outward facing seal surface, the seal member being formed from a first material; and a support structure including a base part and a plurality of spaced apart, radially flexible extensions, the support structure being formed from a second material harder and/or stiffer than the first material. At least a portion of the base part is covered by and/or embedded within the first material, and the plurality of flexible extensions includes an exposed portion that is uncovered by and/or embedded within the first material and defines an axial end of the filter cartridge and is coincident with a radial innermost portion of the end cap. The seal surface and the exposed portion of the flexible extensions are axially aligned such that a plane orthogonal to the longitudinal axis can pass through the seal member and through the exposed portion of the plurality of flexible extensions.

Filter elements and assemblies

According to the present disclosure, air cleaner assemblies, components, features, and methods relating thereto, are described. These features, in part, relate to configuration of a preferred seal arrangement and seal surface of the cartridge. Particular arrangements are shown, in which: the filter cartridge includes a seal arrangement having a axial pinch seal surface with a projection/recess contour including at least one projection thereon; and, the cartridge includes a seal contour projection stabilizing portion at a location in perimeter alignment with the portion of the seal pinch arrangement including the first housing engagement projection. Additional features are included that relate to clean air separator section tubes of a precleaner arrangement secured to a cartridge. These features can be used in cartridges including features outlined above, or in alternative cartridges. Additional features of air cleaner arrangements and filter cartridges in accord with the above are described.

Filter cartridges; air cleaner assemblies; housings; features; components; and, methods

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

Air cleaner assemblies and methods of use

According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

An air cleaner assembly includes a housing and a removable cover. A filter element is removably positioned in the housing. A two-part mating catch assembly includes a first part that is secured to the cover and a second part that is on one of the housing and the filter element. The first part and second part are positioned to releasably mate when the filter element is operably mounted within the housing.

Filter element, air cleaner assembly, and methods

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.

Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.

A two-stage separator system having a housing extending between a first end and a second end. The housing defines a housing inlet, a separator outlet towards the second end, and a filtration outlet on the first end. A filter assembly has a first sheet of filter media coupled to a second sheet of filter media mutually defining a plurality of flutes extending in an axial direction. The filter assembly defines an inlet flow face and an outlet flow face. The filter assembly is disposed in the housing and coupled to the housing about the filtration outlet such that the outlet flow face is in fluid communication with the filtration outlet. The inlet flow face of the filter assembly has an axial flow face length.
