FILTER WITH EXTERIOR AND INTERIOR MEDIA COMPONENTS AND METHOD OF FILTERING

摘要

The invention features a filtration segment having a top seal, a bottom seal and a primary filter core and the method of filtering with the design of the filtration segment. The primary filter core is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. The filtration segment also includes one or more interior filters surrounding the primary filter core. Each interior filter includes a filter material surrounding a secondary core which is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. Each filter may optionally include a retaining medium enclosing the filter material. The filtration segment has one or more layers of an exterior filter media which operatively surround the interior filters and are operatively coupled to the top seal and the bottom seal.

主权项

1. A filtration segment for use in a filter housing comprising:
a top seal; a bottom seal; a generally cylindrical fluid permeable primary filter core between the top seal and the bottom seal operatively coupled to an opening for a fluid flow located on one of either the top seal and the bottom seal, wherein said primary filter core is a void or a cylindrical tube; two or more interior filters spaced around the primary filter core, each interior filter comprising: a filter media surrounding a secondary core and said secondary core operatively coupled openings located on the top seal and bottom seal to allow fluid flow into the interior filter; an exterior filter composed of one or more layers of media extending between the top seal and bottom seal surrounding the interior filters and the primary filter core; and granular filter media distributed in the void inside the exterior filter, surrounding the interior filters and around the primary core.
