Abstract: 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.

Abstract: 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.

Abstract: An air cleaner assembly with a restriction indicator (14) includes a housing (12) having an exterior surface around an interior volume. The housing includes a bore (42) extending through a portion of the exterior surface of the housing surrounded by a bore wall (38) 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 (44) between the bore wall and the receptacle wall. A restriction indicator (14) measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem (46) that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs (52) of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.

Abstract: An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

Abstract: 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.
