Benefits of technology

The present patent is related to filter assemblies and filters. The technical effects of the invention include the creation of filters with improved filtration efficiency, reduced pressure drop, and reduced size. The invention also provides for the creation of filters with a void between layers of filter media, which can improve filtering performance. Additionally, the invention provides for the creation of filters with an inner plenum that can improve filtering performance. Overall, the invention provides filters with better performance and reduced size for improved performance and cost-effectiveness.

Problems solved by technology

As the single surface fills with particulate, the efficiency of the filter begins to decline.

Embodiment Construction

[0048]Provided herein are embodiments of a filter for use in filtering a flowable substance (e.g., air, gas, fluid, and / or liquid) to remove unwanted material (e.g., particulate and / or contaminates) from the flowable substance. The filter embodiments described herein maximize the removal of particulate (e.g., paint, stains, dust / lint, pet dander, pollen, dust mite debris, mold spores, bacteria, microscopic allergens, virus carriers, smoke, odor, smog particles, metal, plastic, sludge, oil) from a flowable substance.

[0049]As used herein the term “filter media” refers to any material capable of removing particulate from a flowable substance (i.e., air / gas or fluid / liquid) including, but not limited to, polyester, thermal or resin bonded polyester, polypropylene, polyurethane, polyethylene, polyethylene foam, polyurethane foam, polyphenylene sulfide, polyolefin plastic, coal, glass, micro glass, spun glass, animal hair, organic fiber, fiberglass, acrylic fiber, paper, paper poly, cotto...

Abstract

A filter includes filter media and defines an inner plenum. The inner plenum has a cross-sectional dimension extending crosswise of the filter. The cross-sectional dimension decreases from adjacent the upstream side toward to downstream wall to a location disposed intermediate the upstream side and the downstream wall. The cross-sectional dimension of the inner plenum increases from adjacent the intermediate location toward the downstream wall.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 114,567, filed Feb. 10, 2015, the entirety of which is hereby incorporated by reference.FIELD OF THE DISCLOSURE[0002]The field of the disclosure relates generally to filter assemblies for use in filtering particulate material from a flow.BACKGROUND OF THE DISCLOSURE[0003]Generally, filters have been fabricated to provide a single surface that facilitates filtration. As the single surface fills with particulate, the efficiency of the filter begins to decline. Accordingly, there is a need for a filter that is increases the useful life of known filters.BRIEF DESCRIPTION OF THE DISCLOSURE[0004]In one aspect, a filter assembly generally comprises a back wall comprising filter media and located on a downstream side. A first aperture is formed on an upstream side. The first aperture has a cross-sectional dimension. At least one sidewall comprising filter media. The at lea...
