Abstract: An air cleaner assembly comprises a housing and a filter element. The housing comprises a first housing end and a second housing end. The second housing end of the housing defines an opening of the housing for fluid flow. The filter element is configured to be received through the first housing end of the housing. The filter element comprises a filter media and a closed endplate. The filter media comprises a first media end and a second media end. The second media end of the filter media defines an opening of the filter element for fluid flow. The closed endplate is positioned along the first media end of the filter media and comprises a wall with an axially inner surface and an axially outer surface. The axially outer surface is exposed to an area outside of the housing and closes off the first housing end of the housing when the filter element is positioned within the housing.

Abstract: A liquid filtration system is provided. The filtration system includes a filter head and a filter cartridge configured to be removably coupled to the filter head. The filter cartridge includes a shell housing and a filter element. The shell housing defines a first housing end, a second housing end, and a housing sidewall extending between the first housing end and the second housing end. The filter element is received within the shell housing and removably coupled to the shell housing. The filter element includes a media pack configured to filter matter from a fluid flowing therethrough and an endcap coupled to an end of the media pack. The endcap comprising a retaining member engaged with the shell housing.

Abstract: A filter cartridge includes a shell, a connecting ring, an end cap, and an axially directed sealing member. The shell defines an inner cavity and an upper lip disposed along an upper edge of the inner cavity. The upper lip defines a channel. The connecting ring is positioned outside of the inner cavity and is engaged with the channel. The connecting ring includes a threaded region extending along a central axis of the shell. The end cap is engaged with the shell adjacent to the upper lip. The axially directed sealing member is positioned between the shell and the end cap and extends axially outward so as to form an axial seal with a filter head when the filter cartridge is installed on the filter head.

Abstract: Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).

Abstract: Various embodiments of two-stage filter assemblies are provided. A filter element of the filter assembly includes a first endplate that is configured to facilitate assembly of the filter element into a filter housing assembly. The first endplate includes a flange that extends radially away from a media pack of the filter and into the channel formed between a lid and a housing of a filter housing assembly. A second endplate of the filter element is coupled to a media pack second end of the media pack. The filter element also includes a first seal member that is coupled to the second endplate. The first endplate and the filter housing assembly are structured to ensure that the filter element is sealingly engaged with the housing when (i) the flange is engaged with the lid and (ii) the lid is fully installed onto the housing.
