Abstract: Referring to the figures generally, rotating filter cartridges (e.g., a rotating coalescers) for a rotating filtration system (e.g., rotating coalescer crankcase ventilation systems) are described. The described filter cartridges use mechanically created seals to seal the filter media to the endcaps of the filter cartridges. Accordingly, the described filter cartridges eliminate the need to use a potting or embedding material during manufacturing of the filter cartridge, thereby eliminating the costs and potential manufacturing defects associated with the potting or embedding material and process.

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: A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.
