A filter element includes a construction of pleated filter media defining an interior volume. First and second opposite end caps are secured to opposite ends of the filter media. A support structure supports the filter media and is operably oriented in the interior volume. The support structure extends from the first opposing interior face to the second opposing interior face. The support structure is provided to extend less than a full extension between the first end cap and second end cap.

Filter element having inner support and methods

A filter arrangement includes first and second media packs with a support core in between. The support core includes a first ring at one end and, optionally, second ring at an opposite end. In some arrangements, at least a first member and second member extend from the first ring while being engagement-free to each other. In some arrangements, no more than a first member extends from the first ring, while being engagement-free relative to itself.

Filter arrangement with support core and methods

A support structure for an interior volume of a construction of pleated media is operably oriented in the interior volume and structurally supports the media. The support structure can pass directly through an innermost 60% of the interior volume. It can have a void volume not more than 80%. It can be inner liner-free and extend in a non-curved path. It can include a first sheet and second sheet of porous material. At least a first brace construction secures the first sheet and second sheet together and in spaced apart, opposing relation. The support structure can include a pleated construction having pleats extending in a direction non-parallel and angled to the direction of pleats of the pleated filter media. The support structure can be molded spacers.

Support structure for pleated filter media and methods

A filter assembly includes a filter head and filter cartridge. The filter cartridge includes a housing and element. The housing includes a can with an open mouth. An interface ring is secured to the can adjacent to the open mouth. The outer ring surface is against the inner wall of the can. The ring wall is angled between the first and second ends greater than one degree and less than 6 degrees. Methods of filtering and making the housing are provided.

Housing for filter element; filter element; methods of use and making

A filter element includes at least first and second opposing pleated media sections and at least first and second support structures supporting, absent an inner liner, the at least first and second media sections and being layered between the at least first and second media sections. In another embodiment, the filter element includes a continuous construction of pleated media forming the first and second opposing pleated media sections, in which the pleats have portions of differing lengths, and a support structure within the interior volume supporting the first and second media sections. The filter element can be in the form of two racetracks, a V-pack, or two V-packs. The racetracks can be polygon shaped.

Filter assembly and methods

Filter element with support core and methods

The current technology relates to a filter element having pleated filter media. The pleated filter media defines an elongate tubular structure having an inner passageway. The pleated filter media has outer pleat folds and inner pleat folds each extending from a first end to a second end of the elongate tubular structure. The filter element has no more than one elongate brace disposed in the inner passageway, extending between the first end and the second end. A plurality of support ribs are coupled to the elongate brace, where each support rib has a connector defining an interference-fit with the elongate brace. Each support rib partially defines the inner passageway and has an outer support surface that abuts a substantial portion of the inner pleat folds.

Described herein are filter assemblies for removing high molecular weight organic components from liquefied petroleum gas, as well as methods for removing high molecular weight components from liquefied petroleum gases. The filter assemblies include an upstream carbon-containing filter media pack and a downstream filter media pack.
