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.

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: 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.).
