Abstract: Referring to the figures generally, a rotating filter cartridge includes a first endcap, a second endcap, and a filter media. The filter media is positioned between the first endcap and the second endcap. The filter media creates a mechanical seal between at least one of the first endcap or the second endcap during rotation of the rotating filter cartridge without the use of a potting material. In at least one embodiment, the rotating filter cartridge further includes a body secured to the first endcap and the second endcap. At least one of the first endcap or the second endcap, and the body, may form a pocket that radially pinches the filter media to form the mechanical seal.

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.

Abstract: An air intake system having an air filter and a cyclonic pre-cleaner is described. The cyclonic pre-cleaner includes a plurality of fins that cause the air flowing through the pre-cleaner to go from a substantially axial flow to a substantially swirling flow. As the air flow through the pre-cleaner increases, the air is swirled at a faster rate, and some contaminant particles in the air will be forced out of the flow of air before reaching the air filter. The air intake system includes a blower unit having a motor, an impeller, and a controller. The blower unit structured to selectively draw more air through the air intake system to increase the flow of air through the pre-cleaner thereby increasing the efficiency of the pre-cleaner.

Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a contact seal to seal a gap between a static side of a housing and a rotating coalescer inlet. The rotating coalescer may be driven mechanically, electrically, hydraulically, or the like. The contact seal can be formed via a soft solid or a liquid film created by oil. Accordingly, the contact seal is a hydrodynamic soft seal. The contact seal prevents the blowby gases from bypassing the filter element of the rotating coalescer. At the same time, the contact seal may be broken during positive blowby gas recirculation circumstances because the contact seal is a hydrodynamic soft seal.

Abstract: Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral “V” shapes).

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: Disclosed is a composite filter media. The composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.
