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 separation assembly comprises a housing and a plate. The housing comprises an inlet and an outlet. The plate is positioned within the housing between the inlet and the outlet. The plate comprises a wall, at least one aperture, and at least one chimney comprising an inner surface surrounding the at least one aperture and an outer surface. The chimney extends from an upstream side of the wall and encompasses only a portion of a flow path between the inlet and the upstream side of the wall such that fluid can flow radially beyond the outer surface of the at least one chimney in the housing between the inlet and the wall.

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 ever similarly configured filter media not having the embossments.

Abstract: An axial flow element for use in a liquid separation system for an internal combustion engine includes a hub, a groove, a locking member, and a flat layer. The hub includes a cylindrical outer surface. The groove is disposed in the outer surface. The groove extends in a substantially longitudinal direction along the hub from a first end of the hub to a second end of the hub. The locking member is disposed in the groove. The flat layer is disposed between the hub and the locking member.

Abstract: An automatic drain device is configured for use with a fuel water separator filter system. The automatic drain device includes a solenoid, a water-in-fuel sensor, and a controller configured to operate the automatic drain device by activating the solenoid in response to a signal from the water-in-fuel sensor. The automatic drain device may be utilized with suction side and pressure side fuel water separator filter systems. The automatic drain device operates independently of any user input.

Abstract: A filter media comprises a first fiber layer and a second fiber layer positioned downstream of the first fiber layer. The first fiber layer has a first geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is greater than 2. The second fiber layer has a second geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is less than 2.

Abstract: Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The filter media is HSRC filter media. As such, the filter media has a higher resistance to compressibility than traditional coalescer filter media, such as filter media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

Abstract: Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.

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 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.
