Abstract: A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

Abstract: A filter assembly includes a support fame, a filter media, and a conditioning device. The filter media is coupled to the support frame. The filter media has a dirty side that receives an air stream and a clean side that outputs the air stream after having been filtered by the filter media. The conditioning device is coupled to the support frame. The conditioning device is positioned downstream of the clean side of the filter media with respect to the air stream and directly contacts the clean side of the filter media.

Abstract: An air-liquid separation assembly for separating air and liquid from an air-liquid mixture comprises a housing through which fluid flows, a main separator positioned within the housing, and a sub-separator. The sub-separator is positioned within the housing before or after the main separator and defines a plurality of slots. Each of the plurality of slots is positioned either between adjacent baffles of the sub-separator or between a baffle of the sub-separator and a portion of the housing. The plurality of slots are positioned next to each other in a direction substantially perpendicular to the direction of fluid flow through the housing. The plurality of slots comprises a first subset of slots and a second subset of slots. The second subset of slots extends at a different angle than the first subset of slots such that fluid flows through the first subset of slots and the second subset of slots at different angles.

Abstract: A fuel filter assembly for filtering a fuel-liquid mixture comprises a filter cartridge and a return tube. The filter cartridge comprises a filter media and a housing. The filter media defines an open central region therein. The housing contains the filter media. The return tube extends into the central region of the filter media. The return tube collects and drains liquid from a bottom inner region of the filter media.

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: Rotating coalescer elements that maximize the radial-projected separation surface area in a given (rotating) cylindrical volume, where flow to be cleaned is passing axially upward or downward through a separating media of the rotating coalescer element. Various example package assemblies are provided with various types of rotating configurations including cylindrical coiled media packs, frustum coiled media packs, concentric cylinders, coiled metal or polymer films with and without perforations, and/or alternating layers of different materials. The described rotating coalescers may be driven by hydraulic turbine, electric motor, belt, gear or by mounting on rotating machine components, such as rotating engine shafts or connected components.
