Abstract: An air filter arrangement is disclosed. The air filter arrangement includes strips of media comprising fluted sheets secured to facing sheets and forming inlet and outlet flutes secured to one another in a stack. Media pack arrangements including such stacked media with peripheral, perimeter, housing seal arrangements are described. Also described are air cleaners including the filter cartridges. Methods of assembly and use are also provided. Also, systems of use are described.

Abstract: Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising strips of fluted material secured to facing sheets, oriented in a stack. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The media pack is non-removably secured within a filter cartridge housing, at a location between opposite sections of a shell, typically secured thereto with an adhesive. The shell also defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack. The closed end is typically curved and the shell typically provides either a d/b-shape or a u-shape. The filter includes an end member, with a outlet flow aperture arrangement therein, allowing for outlet flow from the filter cartridge in a general direction orthogonal to air flow through the media pack.

Abstract: A media pack for including in a filter cartridge of an air filter arrangement, is provided. A variety of configurations for the media pack are described and shown, an example shown being trapezoidal. Filter cartridges including such media packs, air cleaner assemblies and equipment systems are described. Also methods of use assembly are described.

Abstract: A one aspect method of forming filter cartridge arrangements for use in air cleaners is provided. The method involves coiling a media pack with a central winding bead and cutting through the winding bead in the coiled media pack to form two media packs. An example filter arrangement is disclosed. In another aspect, a filter cartridge arrangement for use in air cleaners is provided. The filter cartridge arrangement includes a media pack including a plurality of inlet flutes and outlet flutes extending between first and second opposite flow faces and formed from an arrangement of facing sheet secured to corrugated sheet. An example cartridge includes a preform secured to the media pack. In some forms, the preform includes a grid arrangement extending across one of the flow faces. The grid arrangement can include a region of cured seal material positioned in contact with the first flow face, to secure the grid arrangement to the flow face.

Abstract: A single facer media is provided according to the invention. The single facer media includes a fluted sheet attached to a facing sheet and having a first end and a second end so that when the single facer media is formed into a media pack, the first end or the second end forms a media pack first face, and the other of the first end or the second end forms a media pack second face. Adhesive is provided between the fluted sheet and the facing sheet at the first end or the second end, and wherein the fluted sheet and the facing sheet are pushed together and adhered together at the location of the adhesive to provide a seal between the fluted sheet and the facing sheet. At least 25% of the flutes of the fluted sheet comprise at least one ridge extending along at least 50% of the flute length between adjacent peaks. Filtration media packs, filter elements, and methods for forming a single facer media are provided.
