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: Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic low from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.

Abstract: A filter assembly includes a filter head, a port, a fitting, and a diffuser. The port extends from a portion of the filter head and defines a channel for fluid to flow into or out of the filter head. The fitting first end is attachable to the port and the fitting second end is attachable to a filtration system component. The diffuser is positionable within the channel of the port and comprises an inner surface and an outer surface. The inner surface defines an inner conical hollow region that extends at a nonzero angle between the inner conical hollow region first end and the inner conical hollow region second end such that a first inner diameter of the diffuser at the inner conical hollow region first end is smaller than a second inner diameter of the diffuser at the inner conical hollow region second end.

Abstract: A filter assembly includes a conditioning device that conditions a flow of air upstream of a mass air flow sensor. The filter assembly includes a support frame. The filter assembly further includes a filter media coupled to the support frame, the filter media having a dirty side configured to receive a stream of air and a clean side configured to output a stream of air that has been filtered through the filter media. The filter assembly includes a conditioning device coupled to the support frame, the conditioning device positioned in a downstream direction from the clean side of the filter media with respect to the stream of air, the conditioning device offset from the clean side of the filter media by a separation distance.

Abstract: A separator system comprises a main separator, and an additional separator including one of a pre-separator, post separator, or line-of-sight baffle. The additional separator separates liquid particles from an air/liquid mixture and comprises an inlet, an air outlet, a liquid outlet, and a plurality of posts disposed between the inlet and the air outlet. The posts are arranged in a staggered array and comprise a convex end portion having an impaction surface, a portion of liquid particles from the air/liquid mixture adhering as a liquid film to the impaction surface, and a hook end portion positioned downstream the convex end portion and including hooks having an end and a collection pocket disposed between the impaction surface and the end. The collection pocket collects the portion of liquid particles adhered as the liquid film to the impaction surface.

Abstract: A no filter no filter no run attachment is disclosed. A shell defines a fluid passage from an upstream fluid aperture at a first end for fluid receiving communication with a filtration cartridge to a downstream fluid aperture at a corresponding second end sized and shaped for coupling to a fluid pump inlet. The shell further defines a pin aperture at the first end sized to receive a pin from the filtration cartridge. A divider segments the fluid passage into an upstream portion that comprises the upstream fluid aperture and the pin aperture and a downstream portion that comprises the downstream fluid aperture. The divider also defines an internal aperture that allows fluid communication between the upstream portion and the downstream portion. A ball is disposed in the upstream portion in fluid flow receiving communication with the upstream fluid aperture, and is sized to have a greater diameter than the internal aperture.
