Embodiment Construction

[0034] Referring now to the drawings, in which parts are numbered with like numerals throughout the several views, reference is first made to Figure 1 to Figure 2 , shows an exemplary configuration of fluted filter media that may be used in filter system embodiments of the present invention. In particular, fluted filter media (also known as media with media ridges) can be used in a variety of ways to provide fluid filter constructions. One well known approach is characterized here as a zigzag filter configuration. As used herein, the term "z-shaped filter construction" refers to a type of filter construction in which individual filter flutes in corrugated, pleated, or otherwise formed filter flutes are used to define groups of Longitudinal (typically parallel) inlet and outlet filter flutes for fluid to flow through the media; fluid flows along the length of the flutes at opposite inflow ends (or inflow faces) and outflow ends (or outflow faces) of the media flows between. ...

Abstract

The present invention provides a filter cartridge configured to be removably positioned within an interior opening of a housing, wherein the filter cartridge includes a media pack including an inlet end, an outlet end, and an outer perimeter and at least one of: (a) a frame member at least partially surrounding the media pack, the frame member comprising a shape having a shape different from the shape of the outer perimeter of the media pack; a frame wall; and (b) a housing at least partially surrounding the media pack, the housing comprising housing walls having a shape different from the shape of the outer perimeter of the media pack, and at least partially surrounding the media pack A seal member extending from the inlet end of the media pack, wherein the seal member includes a pinch seal portion spaced from the outer surface of the media pack.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 358,932, filed July 6, 2016, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to filter arrangements typically used for filtering air, such as intake air of an internal combustion engine, and more particularly to filter assemblies comprising a plurality of components arranged in a housing to provide a desired filtering capacity. Background technique [0004] Contaminant materials, such as dust and other particles, may be carried in the air stream. For example, air streams provided to engines of construction equipment, motor vehicles, power generating equipment, combustion furnaces, etc. may carry particulate contaminants that can damage and / or adversely affect the performance of such equipment. In many instances, it is necessary and / or desirable to ...
