    Abstract: A two-stage separator system having a housing extending between a first end and a second end. The housing defines a housing inlet, a separator outlet towards the second end, and a filtration outlet on the first end. A filter assembly has a first sheet of filter media coupled to a second sheet of filter media mutually defining a plurality of flutes extending in an axial direction. The filter assembly defines an inlet flow face and an outlet flow face. The filter assembly is disposed in the housing and coupled to the housing about the filtration outlet such that the outlet flow face is in fluid communication with the filtration outlet. The inlet flow face of the filter assembly has an axial flow face length.

    Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

    Abstract: According to the present disclosure, air cleaner assemblies, components, features, and methods relating thereto, are described. These features, in part, relate to configuration of a preferred seal arrangement and seal surface of the cartridge. Particular arrangements are shown, in which: the filter cartridge includes a seal arrangement having a axial pinch seal surface with a projection/recess contour including at least one projection thereon; and, the cartridge includes a seal contour projection stabilizing portion at a location in perimeter alignment with the portion of the seal pinch arrangement including the first housing engagement projection. Additional features are included that relate to clean air separator section tubes of a precleaner arrangement secured to a cartridge. These features can be used in cartridges including features outlined above, or in alternative cartridges. Additional features of air cleaner arrangements and filter cartridges in accord with the above are described.

    Abstract: 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.
