Abstract: A filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing includes an alignment tab disposed on the second housing end. The alignment tab protrudes from the second housing end towards the first housing end. A filter element is positioned within the housing. The filter element includes a first endcap, a second endcap, and filter media positioned between and extending axially between the first endcap and the second endcap. The filter media defines a central opening extending axially therein. An alignment notch is disposed on the second endcap, the alignment notch protruding from the second endcap toward the first endcap.

Abstract: A rotating separator includes a filter housing extending axially along a longitudinal axis and a filter element positioned within the filter housing. The filter element includes a first endplate and a second endplate operatively coupled to the first endplate, a first element core and a second element core positioned between the first endplate and the second endplate and configured to filter a contaminate from a fluid. An interior cavity is defined between the first endplate, the second endplate, the first element core, and the second element core. Fluid flowing through the filter element enters the interior cavity and is split between and flows in parallel through the first element core and the second element core.

Abstract: A rotating crankcase ventilation filter element comprises a filter media comprising a plurality of filter media layers. A first end cap is positioned on a filter media first end. The first end cap comprises a first end cap main body, and a first plurality of indenting features positioned on the first end cap main body proximate the filter media first end. The first plurality of indenting features contact and indent corresponding segments of the filter media first end, causing the plurality of filter media layers to interlock at the corresponding segments. The interlocking prevents movement of the plurality of filter media layers relative to each other.

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 fluid delivery system for an internal combustion engine and a method of monitoring the fluid delivery system are described. The systems and methods monitor and determine various fluid quality parameters and filter element pressure drop, which can be used to determine real-time estimates of remaining useful life for both the filter element and the fluid. The respective remaining useful life calculations are used by the described systems and methods to determine change intervals for the fluid and the filter element. The change intervals can be synchronized by the systems and methods to reduce the amount of down time due to servicing of the fluid delivery system.

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.
