  • Patent number: 10279300
    Abstract: Air filter cartridges for use in air cleaner assemblies are described. The air filter cartridges typically comprise a stack of strips of fluted media, having an inlet flow face and an outlet flow face. A projection is provided extending outwardly from adjacent the outlet flow face of the media pack, as a projection supporting a seal arrangement. The seal arrangement is typically rectangular, with four straight and four rounded corners. The projection can be configured with open corners, and in some instances comprises tabs, to facilitate flexing of the projection to accommodate variations in a housing seal surface, with which the cartridge is installed. Air cleaner assemblies and components therefor, using cartridges in accord with the descriptions herein, are described.

  • Publication number: 20180361292
    Abstract: 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.
