Abstract: A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end is axially open such that fluid can flow unblocked axially through the first axial end and into the channels. The jet is positioned such that at least a portion of the fluid enters into the turbine through the first axial end.

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: 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.

Abstract: A rotating separator including a filter element extending axially along a longitudinal axis and including a first endplate, a second endplate, and a separating element. The first endplate includes a center tube. The second endplate is coupled to the first endplate and includes a central aperture having a perimeter and receiving the center tube. The filter element also includes an axially extending slot and an axially extending protrusion positioned on one of the first endplate and the second endplate and configured to engage with each other. The first and second endplates form an interior cavity when coupled together. The rotating separator includes a filter structure positioned within the interior cavity.

Abstract: A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded From the head service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.

Abstract: An attachment and retaining mechanism is described for removably attaching a rotating filter element to a rotating shaft. The rotating filter element includes a filter media that is driven by a drive mechanism that rotates the rotating shaft. The filter element is removably attached to the rotating shaft such that the filter element and filtration system can be periodically replaced and/or serviced. In some arrangements, the drive shaft includes a D-shaped section that interacts with a mating section of the filter element sleeve of the rotating filter element. In other arrangements, the drive shaft includes at least one flat drive surface.
