A filtration device may include an adapter, a filter element, and a housing. The adapter may include a collar having an upper rim and a lower rim, a plurality of locking tabs extending from the upper rim, and a plurality of snap members extending from the lower rim. The filter element may include a casing and a plurality of receptacles connected to and arranged around a first outer surface of the casing. The plurality of receptacles are configured to receive the plurality of locking tabs. The housing, which is configured to receive the filter element, includes a shell and a plurality of ramp members that are connected to a second outer surface of the shell. The plurality of ramp members are configure to engage the plurality of snap members.

Air cleaner and preferred components for an air cleaner are provided. In certain arrangements, a band is mounted to the media pack, surrounding the media. Also, the cartridge is non-circular and includes a seal thereon.

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.

A method for controlling display of information on a display device includes storing information corresponding to a broadcast program guide. When a signal is received based on activation of a specific key while the first broadcast program is displayed on a screen, information on the first broadcast program and information on a second program to be broadcast after the first broadcast program is detected. The first broadcast program is then displayed in a first region of the screen simultaneously with the information on the first broadcast program and the information on the second broadcast program in a second region of the screen.

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.

A filter element includes a media pack and a gasket member. The gasket member includes first and second gasket regions separated by a channel. The elements are usable in a dust collector having a dirty air inlet, a clean air outlet, and a tubesheet dividing between an unfiltered and a clean air volume. An element is removably mounted and sealed within the tube sheet. At least one projection angled relative to a plane of the tube sheet extends into the channel of the gasket member. A method of servicing a dust collector includes removing a first filter element from the tube sheet in the housing, and then sealing a second filter element against the tube sheet by orienting at least one projection extending from a plane of the tube sheet into a channel defined by a gasket member secured to the second filter element. An axial force is exerted to form a seal between the gasket member and the tube sheet.

A filter element arrangement is provided which includes a media pack comprising Z-filter media, a preform and an overmold sealing a portion of the interface between the preform and the media pack, and also forming an air cleaner seal for the filter element. The overmold preferably comprises molded, foamed, polyurethane. A variety of media pack shapes can be used.

A filter cartridge arrangement is provided which includes a media pack comprising Z-filter media, a preform and a housing seal member. Improvements in the preform and seal member are described which include: a single beveled surface of the seal member to facilitate installation; and, an inside region of the seal member having a tip adjacent in inwardly directed lip of the preform, to control flash during molding. A variety of media pack configurations and features are described.

Air cleaner and preferred components for an air cleaner are provided. In certain arrangements, a band is mounted to the media pack, surrounding the media. Also, the cartridge is non-circular and includes a seal thereon.

Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media.
