    Abstract: A pulse ring assembly for air cleaner systems that is adapted to produce a pulse ring of gas to clean a filter element. The air cleaner system may include an outer tube and an inner tube configured to receive the inner tube such that at least a portion of an interior surface of the outer tube faces at least a portion of an exterior surface of the inner tube. The outer tube may include a pulse port extending between the interior and exterior surfaces of the outer tube into an outer tube passageway. Filtered air may be configured to flow from a first filter cartridge, through the outer and inner tubes, and to an engine intake. The system may also include a pulse jet apparatus in fluid communication with the pulse port of the outer tube and configured to direct gas through the pulse port towards the first filter cartridge.

    Abstract: A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.

    Abstract: Aspects herein include filter systems including short-range wireless tracking features to detect insertion and/or removal of filter elements from filter systems. In an embodiment, a filtration system is included having a housing including a fluid inlet and a fluid outlet. The housing can define an internal volume. A first filter element can be removably disposed within the housing. A short-range wireless communication tag can be associated with the first filter element. A short-range wireless communication reader can be associated with the housing, the reader configured to wirelessly send data to and receive data from the tag when the reader and the tag are at a distance that is less than or equal to a maximum communication distance. Removal of the first filter element from the housing can cause the distance between the tag and the reader to exceed the maximum communication distance. Other embodiments are also included herein.

    Abstract: A centrifuge system including a centrifuge housing having a cavity at least partially surrounded by an outer shell, a central shaft extending into at least a portion of the cavity, a rotary motion source for rotating the centrifuge housing, and a filter concentrically positioned about the central shaft. The filter includes a first layer adjacent to a second layer, wherein the first and second layers are wound into a roll about a central longitudinal opening. The first layer may include at least one contaminant retention layer and the second layer may include at least one flow defining layer.

    Abstract: An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing body can include a first plurality of lugs, wherein each of the first plurality of lugs has a first engagement surface disposed at a first angle that is oblique to a rotational plane of the cover. A second plurality of lugs can be provided on the cover, wherein each of the second plurality of lugs has a second engagement surface disposed at the first angle. A lock mechanism can also be provided that is disposed on the cover, wherein the lock mechanism includes a lock member axially movable between a locked position and an unlocked position to selectively secure the cover to the housing body.

    Abstract: A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.
