Abstract: Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).

Abstract: A method of manufacturing a media assembly comprises winding a filter media about a center axis into a media roll and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies. The media roll is cut along at least one plane that is parallel to the center axis.

Abstract: 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.

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.

Abstract: Filter media having generally tetrahedral shaped flow channels is described. The filter media is generally formed by a flat filter sheet and a formed sheet. The formed sheet may be formed by a curves and/or pleats in the sheet. The curves and/or pleats form the tetrahedron channels. Embossments, such as dimples, are provided on the crests formed by the curves and/or pleats. The embossments help to maintain spacing between adjacent layers of the filter media, thereby increasing dust holding capacity and decreasing pressure drop over similarly configured filter media not having the embossments.

Abstract: Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.
