A filter cartridge and filter assembly using the filter cartridge is provided. The filter cartridge having a contoured end member to angularly orient and/or axially orient the filter cartridge, and particularly a seal thereof, relative to a filter housing. The filter housing is reconfigurable to allow it to be used in different locations having different spatial configurations.

Air cleaner with high performance seal and media

A spin tube assembly for an engine air cleaner is provided. The spin tube assembly includes a housing, a spin tube panel, a plurality of spin tubes and at least one constrictor. The plurality of spin tubes are supported on the spin tube panel in parallel relation to one another. Each spin tube of the plurality of spin tubes includes a helical element causing air entering the spin tube to rotate such that particles within the air are moved by centrifugal action outwardly against a wall of the spin tube. At least one spin tube of the plurality of spin tubes has a constrictor upstream from the helical element thereof. The constrictor causes a localized restriction of air entering the at least one spin tube compared to the spin tubes without constrictors. Methods of use and configuration are also provided.

Air flow distribution arrangements in pre-cleaner systems

A roll forming method may be used to provide a pleated filter media pack and filter cartridges with channels formed. The pack includes a strip of a filter media extending opposed edges and opposed front and back sides. The strip is pleat tips with spacer structure such as integrally formed embossments maintaining a spacing between pleat panels. The inlet and outlet flow faces are created by the edges of the filter media rather than the pleat tips. Alternating pairs of pleat panels are closed such as by seal beads at the inlet and outlet flow faces.

Pleated channel flow filter and/or roll form method

A filter element includes a filter media having opposite first and second faces, and an outer face extending in a longitudinal direction perpendicular from the first face to the second face. An undulating sealing element is directly bonded to the outer face at a location closer to and offset from the first face. The undulations of the sealing element define an offset region of the outer face of the filter media from the first face, the offset region being defined by an amplitude of the undulations. The filter element may be incorporated into a filter assembly including the filter element enclosed by a filter housing. The sealing element may be made of urethane and be compressible within a mating groove in the filter housing.

Wave seal for filter element

A separator has a first inlet arranged to receive a fluid stream, and first and second separation stages coupled together in series; A pump coupled to the second separation stage generates an area of reduced pressure to draw the fluid stream through the first and second separation stages. One of the stages includes a variable impactor separator comprising a first chamber arranged to receive the fluid stream, and a second chamber coupled to the first chamber through an aperture to accelerate the first fluid stream. The stream is incident upon an impaction surface to separate contaminants from the fluid stream. An actuator adjusts the open area of the aperture according to a pressure differential between fluid pressure in the first chamber and a reference fluid pressure in a third chamber. The other of the separation stages is a second variable impactor separator or a filter media.

Separator

Provided is a filter that filters air flowing from the filter to a downstream component, while preventing fluid from flowing from the filter to the downstream component and preventing a substance, such as urea or fuel, entering the filter from the downstream component from degrading the filter element in the filter. The filter includes a filter element having an interior surface defining an inner chamber and a standpipe extending through the inner chamber and terminating at a point that allows air that flows from outside the filter element through the filter element and into the inner chamber to flow into the standpipe and out of the filter, while preventing fluid flowing from the opposite direction through the standpipe from entering the filter element.

Diesel fuel and urea tank air breather filter

A separator for separating contaminants from a fluid stream has first and second chambers coupled by an aperture through which fluid can pass. An actuator can adjust the crossectional area of the aperture according to a pressure differential between the first chamber and a pressure reference. An impaction surface can deflect the first fluid stream after it enters the second chamber such that contaminants are separated from the stream. A pump generates a pressure differential across the aperture. It includes a third chamber having a second inlet for receiving a second fluid stream into the third chamber. The second inlet includes a convergent nozzle for accelerating the second fluid stream, and a third inlet for receiving the first fluid stream downstream of the impaction surface, the third inlet being arranged relative to the second inlet such that the second fluid stream can entrain and accelerate the first fluid stream.

A regulator () comprising a first chamber (), and second chamber () and an actuator (). The second chamber () is coupled to the first chamber () through an aperture (). The actuator () is arranged to the adjust the size of the aperture () according to a pressure differential between fluid pressure in the first chamber () and a pressure reference (). The rate of change of the cross sectional area of the aperture () is arranged to have a non-linear response to a change in the pressure differential.
