    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.

    Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which primary and secondary filter cartridges, having a media pack and a seal arrangement surrounding the media pack, can be installed. The filter cartridges can include an open end cap with an axially deviating seal arrangement and a plurality of axially extending channels for engaging with ribs on the housing. The filter cartridges can also include extension members extending from the open end cap that include the axially extending channels, entirely or partially. The filter cartridges can also include a guide member extending from the extension members for providing a low friction surface against the housing during installation that allows axial force exerted by the installer to be translated into a rotational force that rotates the filter cartridge during installation.

    Abstract: The current technology relates to a filter element having pleated filter media. The pleated filter media defines an elongate tubular structure having an inner passageway. The pleated filter media has outer pleat folds and inner pleat folds each extending from a first end to a second end of the elongate tubular structure. The filter element has no more than one elongate brace disposed in the inner passageway, extending between the first end and the second end. A plurality of support ribs are coupled to the elongate brace, where each support rib has a connector defining an interference-fit with the elongate brace. Each support rib partially defines the inner passageway and has an outer support surface that abuts a substantial portion of the inner pleat folds.

    Abstract: Disclosed herein, among other things, is an improved filter media construction that comprises multiple layers for improved odor control that can be used for vacuum cleaner air filtration cartridge applications. The filter media comprises anti-microbial ePTFE HEPA filter media to prevent mold growth. The filter media may also be used for air cleaner filtration, central air filtration for home and industrial buildings (HVAC), cleanrooms, and microelectronic devices. In an embodiment, the improved filter media construction comprises at least a PTFE layer, a bi-component layer, and a base layer. In an embodiment the PTFE layer comprises ePTFE. In an embodiment, the bi-component layer comprises non-woven polyethylene/polyethylene terephthalate (PE/PET). In yet another embodiment, the base layer comprises activated carbon. Other aspects and embodiments are provided herein.

    Abstract: The disclosure relates to a fuel filter assembly, a filter element, and a method of draining water from a fuel filter assembly. The fuel filter assembly comprises a filter element with a water collecting space; the filter element being connected to a fuel pipe for feeding an upstream side of the filter element with fuel and for providing filtered fuel from a downstream side of the filter element to a combustion engine or parts thereof; a fuel pump arranged downstream from the filter element, wherein the fuel pump can be operated in a first mode for drawing fuel through the filter element and in a second, reverse mode for feeding fuel back to the filter element; a one-way fuel valve arranged upstream of the filter element allowing for flow towards the upstream side of the filter element; a pressure-actuated one-way drain valve in communication with the water collecting space.
