Abstract: A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.

Abstract: Pleated filtration media, filtration media packs, and filtration elements containing projections are disclosed. The pleated filtration media includes projections on at least one surface, the projections configured to engage adjacent media sheets so as to reduce masking of the media. The pleated media and media pleat packs contain protrusions on the surface of the media. These protrusions are three dimensional structures that are on the surface of the media and are provided by forming the protrusion directly in the filtration media or applying structures, such as adhesive beads, or onto one or both faces of the media. Elongation of the adhesive bead can facilitate greater separation of the adjacent faces of pleated media if desired. These protrusions, also referred to herein as projections or dimples, can either contact each other or contact flat media and keep adjacent media faces from becoming in intimate contact with each other.

Abstract: Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

Abstract: A filter apparatus includes a filter, such as a cartridge, positioned within a housing. The filter apparatus has multiple ports and valves, so as to allow a user to easily switch between a filtration mode of filtering fluids and a maintenance mode of cleaning the filter. The filter can have a filter substrate in a housing and after filtrate builds up on the substrate, the substrate can be cleaned by directing a spray of fluid, such as from a ring of nozzles at the top of the housing, onto the substrate. A maintenance port can be provided to drain the debris washed from the substrate. The filter can switch between a backwash mode and a filtration mode.

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.
