Air filter cartridges are disclosed. Also described are air cleaners including the filter cartridges. Methods of assembly and use are also provided. Also, systems of use are described.

An air filter media construction or arrangement is disclosed. The air filter media construction or arrangement includes facing media secured to fluted media. A preferred projection/receiver arrangement is described. Also, a useful seal arrangement is described. Air cleaner assemblies, methods of assembly and use are also provided.

Various example embodiments relate to filter elements. One such filter element includes filter media having a plurality of flow channels. Each of the plurality of flow channels comprises an inlet having an inlet height and an outlet having an outlet height. The inlet height is larger than the outlet height. The filter media defines an inlet face having an inlet face area and an outlet face having an outlet face area. The inlet face is structured to receive air to be filtered. The outlet face is structured to output filtered air. The inlet face area is larger than the outlet face area.

An air filter media construction or arrangement is disclosed. The air filter media construction or arrangement includes media comprising opposite inlet and outlet flow faces, with a perimeter housing seal. Also described are serviceable filter cartridges and air cleaners including the filter cartridges. Methods of assembly and use are also provided.

Methods of processing filter media sheets to provide geometries therein are provided. Tooling for use in the methods are also provided. The tooling has a low static coefficient of friction relative to the filter media sheet and a sufficient wetting contact angle to prevent sticking of the filter media sheet to the tooling so as to avoid damaging the filter media sheet and to provide consistently formed geometries in the filter media sheet.

A filter moving device is disclosed that is designed to lift and move a filter cartridge stack comprised of individual filter cartridges. The filter cartridge stack, for instance, may comprise a plurality of disk-shaped filter cartridges. The filter moving device is designed to be placed over the stack. The device includes lifting elements that engage the stack for removing the stack from a filter assembly and/or installing the stack in a filter assembly.

Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising fluted material secured to facing sheets. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The cartridge defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack.

A filtration media pack including a plurality of layers of filter media is disclosed. The media pack includes fluted sheets and a facing sheet, with a plurality of flutes extending between the fluted sheets and the facing sheets. In an embodiment, the fluted sheet includes a plurality of protrusions that contact the facing sheet.

An air filter arrangement is disclosed. The air filter arrangement includes media comprising corrugated media secured to facing media and defining a media pack having opposite flow faces. Media pack arrangements including such media are described. Also described are filter cartridges including such media packs and air cleaners including the filter cartridges. Advantageous housing seal arrangements having a pinch seal member and forming a trough are described. Methods of assembly and use are also provided. Also, systems of use are described.

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.
