A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

An air cleaner assembly comprises a housing and a filter element. The housing comprises a first housing end and a second housing end. The second housing end of the housing defines an opening of the housing for fluid flow. The filter element is configured to be received through the first housing end of the housing. The filter element comprises a filter media and a closed endplate. The filter media comprises a first media end and a second media end. The second media end of the filter media defines an opening of the filter element for fluid flow. The closed endplate is positioned along the first media end of the filter media and comprises a wall with an axially inner surface and an axially outer surface. The axially outer surface is exposed to an area outside of the housing and closes off the first housing end of the housing when the filter element is positioned within the housing.

According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

A filter element for filtering a fluid comprising a filter medium pack having an axial inlet side for receiving the unfiltered fluid and a circumferential side forming a radial boundary of the filter medium pack. The filter medium pack is configured for insertion into a housing of a filter system so as to enclose or partly enclose the circumferential side of the filter medium pack with an outer sidewall of the housing. The filter element comprises a bridge seal arrangement having a first collar-shaped portion comprising a first circumferential sealing surface sealingly coupled to the circumferential side of the filter medium pack or sealingly coupled to a border of the axial inlet side, and a second collar-shaped portion comprising a second circumferential sealing surface configured for encircling and sealingly cooperating with the outer sidewall of the housing.

A filter element for a dirt suction device is provided, with a filter frame, on which a filter medium is attached, wherein on the filter frame, a continuous seal is arranged, the inner circumferential surface of which is arranged on an outer circumferential surface of the filter frame and has a section that radially protrudes over the filter frame, wherein a groove is arranged on a front side of the protruding section of the seal, and that a sealing surface is arranged on the opposite front side of the protruding section of the seal.

Described is a housing (18) for a separating device (12) for separating fluid from a gas, a housing cover (28) and a connecting part (16) of a device (12) and a device (12) for separating a fluid. The housing (18) has at least one first gas passage (82), which is centrally disposed relative to an axis (30) on a connection device (14). The housing (18) has at least one second gas passage (52), which is disposed radially outside the at least one first gas passage (82) with respect to the axis (30). The housing (18) has at least one fluid outlet (36, 48, 64) for fluid separated from the gas, which is disposed radially between the at least one first gas passage (82) and the at least one second gas passage (52) with respect to the axis (30). Between the at least one second gas passage (52) and the at least one fluid outlet (36, 48, 64), at least one housing-side fluid outlet sealing part (66) of at least one fluid outlet sealing device (92) is disposed, which is configured to sealingly interact with at least one corresponding connection-side fluid outlet sealing part (68) of the connecting part (16), which is provided for connecting the housing (18) with the connection device (14).

A filter module for filtering a fluid is provided with a filter element that has a filter bellows of a filter medium and is provided with a designated raw side and a designated clean side oppositely positioned relative to the designated raw side. A fastening frame is connected to the filter element and has a frame wall enclosing circumferentially at least partially a rim of the filter element. A circumferentially extending first sealing element is arranged on an exterior side of the frame wall of the fastening frame. The fastening frame has at least one locking element on an exterior side of the fastening frame. A second sealing element that seal the raw side and the clean side relative to each other is arranged on the filter element. The second sealing element can be guided into a sealing position upon locking of the at least one locking element in the installation position of the filter module.

A filter assembly has a main filter element disposed in a filter housing and provided with an end disk with a first sealing element that seals the main filter element relative to the filter housing. A secondary filter element is disposed in the filter housing and is provided with an end disk with a second sealing element that seals the secondary filter element relative to the filter housing. The end disk of the secondary filter element is arranged relative to an axial direction of the filter assembly between the end disk of the main filter element and the filter housing. The end disk of the secondary filter element is arranged inside a flow cross section of a fluid outlet of the filter housing. The end disks of the main filter element and of the secondary filter element are axially supported on each other at least over sections thereof.

An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner. The housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.

A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.
