Abstract: Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media.

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 shutoff vent is disclosed. A main body has a first end and a second end. The main body defines a first opening towards the first end, a second opening towards the second end, and a mating port between the first opening and the second opening. The first opening and the second opening are in communication through the mating port to define a gas passageway. A translatable plug is disposed within the main body, and the gas passageway extends past the translatable plug. The translatable plug is configured to reversibly translate towards the second end to sealably obstruct the mating port. In some examples, the translatable plug is configured to translate towards the second end when force is applied to the translatable plug from the first end.

Abstract: An air 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 of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered air flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered air from flowing out of the second portion of the plurality of flutes so that air passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the air. The fluted sheet includes repeating internal peaks facing toward the facing sheet and repeating external peaks facing away from the facing sheet. In addition, the fluted sheet can include at least one ridge extending along at least 50% of the flute length between an internal peak and an adjacent external peak. Additional characterizations of an air filtration media pack, air filtration media, and methods of making and using are provided.

Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.
