Abstract: Filter cartridges including tubular filter media having ovate cross-sections and filter systems using the ovate tubular filter cartridges are described herein. The inner perimeters of the ovate cross-sections of one or more of the filter cartridges may be asymmetric, i.e., the inner perimeters of the cross-sections of the tubular filter media in the filter cartridges may have no lines about which they are symmetric. The inner perimeters of the ovate cross-sections of the tubular filter media in one or more of the filter cartridges may have only one line of symmetry

Abstract: Filter media includes a filtration substrate having a first side and a second side, and constructed for filtering a fluid by flow of the fluid therethrough. The filtration substrate has a a machine direction extending from a first end to a second end, and a cross direction extending from a first edge to a second edge. The filtration substrate includes a plurality of corrugations extending in the machine direction. The plurality of corrugations include a plurality of first crests formed along the first side and a plurality of second crests formed along the second side. The filtration substrate includes a plurality of bosses along the plurality of first crests or along the plurality of second crests and extending in a direction away from the other of the plurality of first crests or the plurality of second crests. Media packs, filter elements, and methods of making are provided.

Abstract: The air filter systems described herein include one or more pulse collectors and pulse generators aligned along pulse axes. The pulse generators and filter elements may be arranged along a pulse distance as measured from a pulse outlet to a filter element opening. The pulse collectors and the filter elements may have openings with a relationship between them within parameters described herein. The pulse collectors may have a relationship between their hydraulic diameter and their length within parameters described herein. The pulse collectors may include a filter section and a pulse section that meet at a junction along a length of the pulse collector. The pulse sections may have a hydraulic diameter that increases when moving from the junction to the tube sheet opening of the pulse section. The filter sections may have a hydraulic diameter that remains constant when moving from the junction to the filter end opening of the filter section. Filter elements/cartridges used in the air filter systems may have filter media shaped or formed into ovate cross-sections

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: A multi-faceted family of non-woven webs that can take the form of a filter media, an adaptable forming process and a machine capable of making the range of media are disclosed. The filter medium can have a first surface and a second surface defining a thickness. The medium can comprise a region having a gradient. Such a gradient is formed by having a medium wherein the concentration of a fiber, a property or other component varies from one surface to the next surface. The gradient region of the media can comprise the entire thickness of the medium or can comprise a region that comprises a portion of the media thickness. The media are characterized by the presence of a continuous change of the fiber concentration or property within the region.
