The present disclosure is directed towards filter elements whose overall length can be adjusted such that the filter element can be installed through an opening in an air cleaner opening having a relatively smaller dimension than the maximum dimension of the filter element. In one aspect, the filter element can include a radial seal member disposed on a positionable coupling element circumscribing at least a portion of a filter medium pack. The filter element has a first axial length when the positionable coupling element is in an extended position and has a second axial length when the positionable coupling element is in a collapsed position, wherein the first axial length is greater than the second axial length. In some examples, the filter element includes two positionable coupling elements.

A sealed intake air system incorporates a positive connection seal interface between the air filter and the airbox with captive fasteners to provide a positive connection between the air filter and the one-piece airbox.

An extraction arm for an extraction device includes a suction pipe and a suction head and defines a suction path that extends from an extraction region in the surroundings of the suction head through the suction pipe to the extraction device. The extraction arm includes an exchangeable filter which is arranged within the suction path. The filter is located in a filter housing which has a main body and a closable cover. The filter is exchangeable, which makes it very easy to prepare the extraction arm for a new application. Since the filter is arranged in front of the suction pipe, the suction pipe remains clean. The filter can easily be changed, whereby disinfection or cleaning of the suction pipe is not necessary.

A filter housing (12) has a first housing part (24) having at least one openable installation opening, at least one inlet opening for fluid to be cleaned, and at least one outlet opening for cleaned fluid. At least one second housing part (26 is configured to close off the at least one openable installation opening, and at least one latch (186) is configured to secure the at least one second housing part (26) in its closed position on the first housing part (24). The at least one latch (186) includes at least one lever element (188), at least one pulling element (190) and at least one elastic connecting element (192). The at least one lever element (188) is connected in a force-transmitting manner to one of the two housing parts (26) by means of at least one swivel mount (210) at least in the closed position. At least one pulling element (190) is connected in a force-transmitting manner to the lever element (188) at one end by means of at least one elastic connecting element (192). At least one pulling element (190) is connected in a force-transmitting manner to the other of the two housing parts (24) at the other end at least in the closed position.

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 body can include a first plurality of lugs, wherein each of the first plurality of lugs has a first engagement surface disposed at a first angle that is oblique to a rotational plane of the cover. A second plurality of lugs can be provided on the cover, wherein each of the second plurality of lugs has a second engagement surface disposed at the first angle. A lock mechanism can also be provided that is disposed on the cover, wherein the lock mechanism includes a lock member axially movable between a locked position and an unlocked position to selectively secure the cover to the housing body.

A filter element has a filter medium body surrounded by a frame with two engagement elements arranged at a side face of the frame and extending away from the filter medium body that engage in a locked state with correlated engagement element counterparts at a filter housing. A rigid element connects the engagement elements to the side face. The engagement elements disengage the correlated engagement element counterparts in a released state and have a first distance to each other in the released state and a second distance to each other in the locked state that differs from the first distance. The engagement elements are connected by an elastic element to the rigid element. The elastic element, when the engagement elements transition from the locked into the released state, generates a restoring force acting on the engagement element.

An ambient air purification device has a filter device arranged in a filter receiving region of its housing. The filter device has a main filter element and a prefilter element, each having a circumferential frame device. A clamping force generating device is provided in the housing to exert an axial clamping force on the frame device of the main filter element resting, when mounted, at the frame device of the prefilter element. The clamping force is transmitted to the frame device of the prefilter element and presses the latter seal-tightly via a seal against a circumferential contact shoulder of the filter receiving region to seal the filter device in the filter receiving region. The frame device of the main filter element is sealed indirectly by the frame device of the prefilter element in relation to the housing and has no seal location of its own in relation to the housing.

Embodiments of the present application disclose a filter device and an all-terrain vehicle. The filter device includes: a body having an accommodating chamber and a mounting port in communication with the accommodating chamber; a filter assembly provided in the accommodating chamber, the accommodating chamber being provided with a first support portion therein, the first support portion supporting a first end of the filter assembly, the accommodating chamber being divided into an intake chamber and an outtake chamber by filter assembly; and an end cap member detachably provided to mounting port, an inner side of the end cap member being provided with a second support portion, the second support portion supporting a second end of the filter assembly.

A filter assembly includes a body of filter media, a seal, and a compression ring. The body of filter media having a first end surface, a second end surface spaced apart from and opposing the first end surface, and an outer surface extending between the first end surface and the second end surface. The seal surrounds the first end surface. The compression ring is disposed about the second end surface. The compression ring includes a first channel configured to allow fluid communication between the second end surface and the outer surface.

A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.
