Abstract: A filter element includes first filter media, second filter media, a frame, and a seal member. The frame is coupled to the first filter media and the second filter media, the frame securing the first filter media and the second filter media into a V-shape. The seal member is attached to and extends from the frame. The seal member includes a U-shaped channel structured to receive a ridge of a housing when the filter element is installed in the housing. The seal member is structured to form a seal between the filter element and the housing when the filter element is installed in the housing.

Abstract: A filtration system comprising a housing defining a central compartment, an outlet and a housing sealing surface having a first non-planar surface. A cover is removably coupled to the housing. The cover defines an inlet and comprises a cover sealing surface having a second non-planar surface. The filtration system also includes a filter element comprising a filter media and a seal member. The filter element is removably received in the central compartment. The seal member comprising a complimentary non-planar sealing surface that matches the first non-planar surface and the second non-planar surface such that the seal member axially pinched between the housing and the cover by the housing sealing surface and the cover sealing surface to form a first seal between the seal member and the housing and a second seal between the seal member and the cover.

Abstract: Various embodiments relate to a filter element. The filter element includes a first endplate that defines a first endplate opening and a second endplate. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A support structure is disposed within the central opening of the filter media and is attached to the first endplate and the second endplate. The support structure includes an axial lobed extension that extends from a first end of the support structure to a second end of the support structure. The support structure is configured to resist collapse of the filter element.

Abstract: A filter element including a first endplate, a second endplate, filter media fitted between the first endplate and the second endplate, the first endplate including an opening that allows a working fluid to flow into or out of the filter media, the filter media allowing the working fluid to be filtered through the filter media and a seal member having an oval profile disposed on the first endplate and configured to seal with a filter housing, the seal member including an inner perimeter and an outer perimeter including a plurality of outwardly curved surfaces.

Abstract: A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

Abstract: Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a first alignment portion disposed on the first housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element comprises filter media and a second alignment portion disposed on the first filter end. The second alignment portion is complementary to the first alignment portion. The installation of the filter element within the housing causes the first alignment surface and the second alignment surface to align to provide for engagement of a radial seal between the filter element and the housing.

The frame is coupled to the first filter media and the second filter media, the frame securing the first filter media and the second filter media into a V-shape. The seal member is attached to and extends from the frame. The seal member includes a U-shaped channel structured to receive a ridge of a housing when the filter element is installed in the housing. The seal member is structured to form a seal between the filter element and the housing when the filter element is installed in the housing.

Abstract: A filter assembly may include a housing and a cover movably connected to the housing and movable between an open position and a closed position. The filter assembly may also include at least one projection extending from the cover towards an interior of the housing and a filter element that fits at least partially within the housing. When the cover is moved from the open position to the closed position, at least one projection interfaces with the filter element and causes the filter element to pivot within the housing, such that the at least one projection seals the filter element and the housing together when the cover is in the closed position.

Abstract: A dual flow filter element includes inner and outer closed loop filter media and inlet and outlet end caps, and having a given shape-in-shape configuration. A support frame extends axially from one of the end caps toward the other end cap and terminates at a termination position between one-fourth and three-fourths of the axial distance between the inlet and outlet ends. Combinations using pleated filter media include a first group of pleat tip ends which are exposed, and a second group of pleat tip ends which are fully potted. One embodiment includes axially offset inner and outer closed loop filter media.

Abstract: A filter assembly, including an air cleaner, has an auxiliary flow component having a mounting flange extending into a gap between a housing port and a conduit in trapped relation to mount the auxiliary flow component to the port and the conduit at the interface thereof. The port and conduit are mounted to each other with the mounting flange therebetween in permanently captured sandwiched relation, without detachment fasteners.

Abstract: A resonator includes an inner perforated tube, an outer shell, and a plurality of annular ribs extending radially therebetween and defining resonant chambers. Progressive stepping of ribs and grooves enables axial insertion assembly with minimal cost. The need for welding or secondary bonding operations is eliminated.

Abstract: A filter includes first and second axially spaced end caps having filter media extending axially between the end caps and extending in a closed-loop around a perimeter defining a hollow interior communicating with an axial flow opening through one of the end caps. One or more columns extend axially in the hollow interior between the end caps and are laterally spaced from the axial flow opening and have hollow sub-interiors for receiving one or more posts extending axially thereinto from a base for mounting the filter to the base in axial compression and with a wiper seal.
