Abstract
Certain embodiments of the invention may include filters and methods for imparting structural support to a pleated filter material. According to an example embodiment, the method includes forming a filter structure from one or more sections of pleated filter media, wherein the filter structure comprises one or more filter pleats. The method also includes extruding a banding material to form one or more radial support regions in at least circumferential contact with at least one of an inner or an outer surface of the filter structure, and maintaining spacing between the one or more filter pleats of the filter structure with the one or more radial support regions.
Claims18
A method for imparting structural support to a pleated filter material, the method comprising:
- forming a filter structure from one or more sections of pleated filter media, wherein the filter structure comprises one or more filter pleats;
- extruding a thermoplastic polyester elastomeric (TPE) material to form one or more radial support regions in at least circumferential contact with an inner surface and an outer surface of the filter structure;
- and
- maintaining spacing between the one or more filter pleats of the filter structure with the one or more radial support regions.
A filter cartridge for filtering particles from a gas or liquid, comprising:
- a filter media comprising a plurality of pleats and arranged in a substantially cylindrical or conical shape about an axis;
- at least one end cap wherein at least a portion of the filter media is secured to the at least one end cap;
- and
- one or more radial support regions in circumferential contact with an inner surface and an outer surface of the filter media, wherein spacing of at least some of the plurality of pleats is maintained at least in part by the one or more radial support regions, and wherein the one or more radial support regions comprise extruded thermoplastic polyester elastomeric (TPE) material.
A filter cartridge configured for filtering particles from a gas or liquid, comprising:
- a filter media comprising a plurality of pleats and arranged in a substantially cylindrical or conical structure about an axis;
- and
- one or more radial support regions in circumferential contact with an inner surface and an outer surface of the filter media, wherein spacing of the plurality of pleats is maintained at least in part by the one or more radial support regions, and wherein the one or more radial support regions comprise extruded thermoplastic polyester elastomeric (TPE) material.
