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.

Filter systems, elements and methods with short-range wireless tracking features

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.

Pulse ring assembly for air cleaner systems and methods thereof

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

Air cleaner assemblies and methods of use

Air cleaner assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. Methods of assembly and use are described.

Filter elements, air cleaner assemblies, and methods of use and assembly

Filter assemblies, components therefor, and features thereof are described. Also described are methods of assembly and use. In depicted examples, the air cleaner assemblies and components use advantageous housing seal features. Also, methods of assembly and use are described.

Filter assemblies; components and features thereof; and, methods of use and assembly

Aspects herein include filtration systems with multitiered data exchange capabilities. In an embodiment, a filtration system with multitiered data exchange capabilities is included. The system can include a first data communication tier including a filter element, the filter element storing data, and a first sensor. The system can include a second data communication tier including a reader device in communication with the first sensor. The system can include a third data communication tier including an engine control unit (ECU) in communication with the reader device, wherein the ECU stores data. The second data communication tier receives data from the first data communication tier and the third data communication tier. The second data communication tier executes operations on the received data to create a processed data set. Further, the second data communication tier sends the processed data set to the third data communication tier. Other embodiments are also included herein.

Filtration systems with multitiered data exchange capabilities

An air cleaner assembly includes a housing and a removable cover. A filter element is removably positioned in the housing. A two-part mating catch assembly includes a first part that is secured to the cover and a second part that is on one of the housing and the filter element. The first part and second part are positioned to releasably mate when the filter element is operably mounted within the housing.

Filter element, air cleaner assembly, and methods

The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Filter media configurations

A filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered fluid flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered fluid flowing out of the second portion of the plurality of flutes so that fluid passing into one of the first face and the second face of the media pack and out the other face of the media pack passes through media to provide filtration of the fluid.

Filtration media pack, filter element, and methods

Embodiments include an air filtration media element comprising a plurality of layers of fluted media, each layer comprising a facing sheet and a fluted sheet, the fluted sheet comprising a first plurality of flutes and a second plurality of flutes, the first and second plurality of flutes being arranged in a parallel flow configuration; wherein the first and second plurality of flutes exhibit regular repeating differences in flute shape, flute size, flute height, flute width, cross-flute area, or filter media.

Filter media, filter media packs, and filter elements

Aspects herein include filter elements and filtration systems. In an embodiment, a filter element for a filtration system is included. The filter element can include a filter body and a filter media disposed within the filter body. A wireless power receiver can be associated with the filter body. The wireless power receiver can include a receiving antenna, a control circuit in electrical communication with the wireless power receiver, and a feedback channel circuit in communication with the control circuit and configured to transmit through a channel separate from the receiving antenna. Other embodiments are also included herein.

Filtration systems, filter elements and methods with wireless power transmission and separate signal output

Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.
