Abstract: Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

Abstract: Filter media having a design embossed into the media are described. In some arrangements, the filter media is pleated filter media. In other arrangements, the filter media includes a plurality of channels, such as tetrahedron channels. The filter media includes a pattern of interrupted straight or angled embossments that help maintain separation between adjacent layers of the filter media. The embossments allow for two adjacent media layers (e.g., mating surfaces of the filter media) to remain separated, thereby increasing dust holding capacity and lowering pressure drop over similarly configured filter media not having the embossments.

Abstract: Radial seal filter assemblies and filter cartridges are described. According to various embodiments, a filter includes a housing that extends along an axis between first and second axial ends. A primary filter element is disposed in the housing and axially extends between first and second axial ends that respectively are adjacent the first and second axial ends of the housing, the primary filter element has a hollow interior and a first axial length. A secondary filter element is disposed in the hollow interior of the primary filter element, the secondary filter element having a second axial length, the second axial length being longer than the first axial length of the primary filter element. The filter further includes an end cap disposed on the second axial end of the primary filter element.
