Abstract: A filtration system includes an air cleaner housing and a filter element. The air cleaner housing includes a base and a removable cover. At least one of the base or the cover defines a cavity and a protrusion extending into the cavity. The filter element is disposed within the cavity. The filter element includes a plurality of media blocks each including a pleated filter media. The plurality of media blocks are arranged in arch shapes of approximately equal inner radii. The plurality of media blocks are coupled to each other along opposing edges that extend along a pleat direction of the pleated filter media. The media blocks together define at least one void that extends along the protrusion. The protrusion occupies a portion of the void.

Abstract: A gas-liquid separator comprises a housing comprising a first inlet structured to receive a blowby gas stream, the blowby gas stream having a first flow velocity, and a second inlet structured to a communicate a compressed gas into the housing, at least a portion of the second inlet disposed within the first inlet. An elastomeric nozzle is coupled to the first inlet and positioned around the second inlet, the elastomeric nozzle structured to combine the blowby gas stream with the compressed gas such that the compressed gas causes the blowby gas stream to flow at a second flow velocity that is greater than the first flow velocity. An impaction plate is disposed downstream of the elastomeric nozzle such that the blowby gas stream impacts the impaction plate and separates liquid and aerosol contained in the blowby gas stream.

Abstract: A rotating crankcase ventilation system comprises a housing comprising an inlet and an outlet, a motor comprising a stator and a rotor, and a shaft. A first end of the shaft is coupled to the rotor and configured to rotate in response to rotation of the rotor. A filter element is coupled to the shaft. A sensor is configured to measure at least one operating parameter of the rotating crankcase ventilation system. A controller is operatively coupled to the sensor and the motor, the controller configured to receive the at least one operating parameter and selectively adjust operation of the motor to adjust rotation of the rotor, and thereby, the filter element based on the at least one operating parameter.

Abstract: A spin-on filter comprises a housing shell, a filter element, a nutplate, and a gasket. The filter element is positionable within the housing shell and comprises a filter media and an endplate. The nutplate is positionable within the housing shell. The gasket comprises a central body and a spring-loaded extension. The spring-loaded extension circumferentially surrounds and extends radially from the central body. The spring-loaded extension is axially flexible between an expanded position and a compressed position. The spring-loaded extension forms and maintains a first seal with the endplate and maintains contact with the nutplate as the spring-loaded extension moves between the expanded position and the compressed position.

Abstract: A dry material transfer pump comprises an outer tube including an outer tube channel having an upstream end that is axially aligned with a downstream end thereof, and a plenum portion having a cross-sectional width that is larger than a cross-sectional width of the outer tube channel. A pressurized gas inlet is defined through the outer tube and is in fluid communication with the plenum portion. An inner tube is disposed annularly within the outer tube channel and defines an inner tube channel configured to receive particulate matter. At least one opening is defined radially through a wall of the inner tube and fluidly couples the plenum portion to the inner tube channel to allow the pressurized gas to flow from the plenum portion into the inner tube channel and create suction within the inner tube channel for drawing the particulate matter through the inner tube channel.

Abstract: A filter cartridge includes a shell, a connecting ring, an end cap, and an axially directed sealing member. The shell defines an inner cavity and an upper lip disposed along an upper edge of the inner cavity. The upper lip defines a channel. The connecting ring is positioned outside of the inner cavity and is engaged with the channel. The connecting ring includes a threaded region extending along a central axis of the shell. The end cap is engaged with the shell adjacent to the upper lip. The axially directed sealing member is positioned between the shell and the end cap and extends axially outward so as to form an axial seal with a filter head when the filter cartridge is installed on the filter head.
