A cover for an air intake box that is installed within an engine bay of an automobile and beneath a hood of the automobile is presented. The air intake box comprises an air filter and a housing. The cover comprises a base structure configured to be mounted to the housing. The base structure has an opening sized to allow access to the air filter. A hood is configured to be mounted to the opening, wherein the hood is sized to seal the opening. The hood is configured to uncover the opening and comprises a decorative ornamentation and is replaceable and interchangeable. The base structure and the hood are configured to seal the air intake box when the cover is installed on the housing.

A filter bank includes a filter enclosure. A first filter panel and a second filter panel are flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge. A first sealing gasket extends along a distal end of the first filter panel and forms a first air seal within the filter enclosure. A second sealing gasket extends along a distal end of the second filter panel and forms a second air seal within the filter enclosure. A third sealing gasket extends along the living hinge. A pivoting sealing rail pivots within the filter enclosure to form a third air seal against said third sealing gasket extending along the living hinge.

A filter element for a filter for filtration of a fluid is insertable along an insertion direction into the filter. The filter element is provided with a filter medium to be flowed through along a main flow direction. The filter element has a clean side and a raw side. A sealing surface surrounds the filter medium, wherein the sealing surface, interacting with a filter housing of the filter when the filter element is in an installed state in the filter housing, separates the clean side from the raw side. A support edge exerts a force on the sealing surface by interacting with the filter housing of the filter when the filter element is in the installed state in the filter housing. The sealing surface and the support edge are positioned at an acute angle relative to each other.

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.

Air cleaner assemblies, components, features and methods of assembly and use are described. Example air cleaner assemblies are depicted and described in which a main filter cartridge sealing surface is recessed from an open end of a housing body. An access cover of the housing is configured with a portion extending inwardly to engage a main filter cartridge portion and bias it against the main filter cartridge sealing surface. In selected assemblies, the portion of the access cover extending inwardly toward the main filter cartridge, is a precleaner having flow separator tubes therein.

A filter element (100) that is to be mounted in a housing (102) has at least one substantially hollow cylindrical pleated filter (10, 20) designed to separate liquid from aerosol, and two cover elements (30, 40) designed to cover axial end regions (12, 14, 22, 24) of the pleated filter (10, 20). The axial end portions (12, 14, 22, 24) of the at least one pleated filter (10, 20) are pressed against the cover element (30, 40) by an axial compressing force. The at least one pleated filter (10, 20) is secured in the axial direction, and one respective sealing zone (16, 18, 26, 28) is formed between each pleated filter (10, 20) and each cover element (30, 40).

A filter cartridge configured to be removably positionable within an inner opening of a housing, wherein the filter cartridge includes a media pack having an inlet end, an outlet end, and an outer surface having an outer peripheral shape, at least one of: (a) a frame member at least partially surrounding the media pack, the frame member including a frame wall having a shape that is different from the outer perimeter shape of the media pack; and (b) a shell at least partially surrounding the media pack, the shell including a shell wall having a shape that is different from the outer perimeter shape of the media pack, and a sealing member extending at least partially around the inlet end of the media pack, wherein the sealing member connects the media pack to at least one of the frame member and the shell.

A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally comprises z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.

An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.
