Abstract: An internal combustion engine crankcase ventilation rotating coalescer includes an annual rotating coalescing filter element, an inlet port supplying blow by gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering clean separated, air from the exterior of the rotating element. The direction of flow by gas inside-out, radially, outwardly from the hollow interior to the exterior.

Abstract: An axial flow air filter system is described. The system includes an axial flow filter element having a filter media. The filter media includes an inlet face and an outlet face, the inlet face spaced apart from the outlet face. The axial flow filter element includes an upper support ring adjacent to the inlet face of the filter media. The upper support ring circumscribes the filter media and supports an upper seal. The upper seal forms a seal with a housing when the filter element is received in the housing. The axial flow filter element further includes a lower support ring adjacent to the outlet face of the filter media. The lower support ring circumscribes the filter media. In some arrangements, the lower support ring does not include a seal.

Abstract: Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.

Abstract: A filter element including a first filter media pack with an inlet face and an outlet face and a second filter media pack with an inlet face and an outlet face. The second filter media pack is formed separately from the first filter media pack and is coupled to the first filter media pack such that the respective inlet faces and outlet faces of the first and second media packs do not overlap. The first filter media pack and the second filter media pack each include a corresponding filter media pack characteristic, and the filter media pack characteristic of the first filter media pack is different from the corresponding filter media pack characteristic of the second filter media pack. Exemplary filter media pack characteristics include the length, width, height, shape, media density, layer spacing, pleat bend angle, pleat density, and material composition of the first and second filter media packs.

Abstract: One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.

Abstract: A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

Abstract: A fluid filtration system may include a fluid filter assembly that includes a filter element configured to filter a fluid and a sensor probe incorporated into the fluid filter assembly. The sensor probe may include a chemically reactive material sensitive to at least one property of the fluid and at least a portion of the sensor probe may be exposed to the fluid.

Abstract: A filter assembly for separating liquid from a fluid mixture that includes a filter housing with an inner surface, a filter element configured to separate a liquid from a fluid mixture and defining an outer surface, and a porous filter media. The filter element is positioned within the filter housing such that the outer surface of the filter element faces the inner surface of the filter housing. The porous filter media is attached to the inner surface of the filter housing to facilitate drainage of the liquid through the filter housing and prevent liquid carryover after the fluid mixture flows through the filter element.

Abstract: A filter element is described that includes an endplate that also serves as the lid or cover for the filter housing. The combined endplate/lid includes a central hole that is closed to fluid flow when the proper filter element-housing combination is used. Various embodiments for different functional uses of the central hole are also described.

Abstract: This disclosure describes a filtration system and method for removing soap from diesel fuel. The removal involves passing fuel through the filtration system. By removing soap, injector sticking and plugging can be reduced and for fuel already contaminated with soap, lubricity and/or corrosion inhibition functionality resulting from the conversion of carboxylic acid additives can be restored to metal carboxylates.

Abstract: A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.
