Abstract: An air cleaner assembly comprises a filter element and a housing assembly. The filter element comprises a filter media for filtering a fluid and a first endcap positioned along a first end of the filter media and through which a first filtered air flow portion flows. The housing assembly at least partially contains the filter element and comprises a cover that defines a first outlet through which the first filtered air flow portion flows to a downstream device. The cover comprises a noise reduction device that receives the first filtered air flow portion and dissipates sound waves traveling upstream from the downstream device.

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: A media pack includes a filtration sheet and a support sheet that is made from a different material than the filtration sheet. The filtration sheet is coupled to the support sheet. The support sheet is corrugated such that, together, the filtration sheet and the support sheet form a plurality of channels. The channels are alternately sealed on opposing ends of the media pack. In one embodiment, the permeability of the support sheet is less than a permeability of the filtration sheet.

Abstract: Various example embodiments relate to a filtration system. The filtration system includes a filter housing having a first housing end and a second housing end. The filter housing includes a housing cover defining an outlet. The housing cover includes a first guidance element extending from an internal portion of the housing cover axially away from the outlet. A second guidance element extends from the internal portion of the housing cover axially away from the outlet. A filter element has a first filter end and a second filter end. The filter element includes an end cap adjacent the first filter end and defining an end cap opening therethrough. The end cap includes a channel around the end cap opening. Filter media has a first media end and a second media end. The filter media extends axially from the first media end toward the second media end.

Abstract: A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first endcap is positioned on a filter media first end of the filter media, and a second endcap positioned on a filter media second end of the filter media. the second endcap coupled to the first endcap such that the first endcap and the second endcap define an internal volume within which the filter media is disposed. The second endcap comprises an axial seal member extending from a surface of the second endcap towards the filter media and forming an axial seal with the filter media. The axial seal member projects substantially parallel to a direction of axial fluid flow entering the filter media.

Abstract: A rotating crankcase ventilation filter element comprises a motor comprising a stator and a rotor, and shaft. A first end of the shaft is coupled to the rotor and is configured to rotate in response to rotation of the rotor. A hub is disposed circumferentially around the shaft and coupled to the shaft such that the hub is rotationally locked with respect to the shaft. A filter media is disposed around the hub and secured thereto such that the filter media is rotationally locked with respect to the hub. The filter media is structured for axial flow of a gas through the filter media. A first end cap is disposed on a filter media first end, and a second end cap is disposed on a filter media second end of the filter media. The second end cap is coupled to the first end cap such that the filter media and the hub is secured therebetween.
