FILTER ARRANGEMENT; SEALING SYSTEM; AND METHODS

摘要

A filter pack includes a filter construction and a sealing system for sealing the construction within a duct or housing. The filter construction has first and second opposite flow faces and is configured for a straight-through flow. The sealing system includes a frame construction and a compressible seal member. The compressible seal member is molded around a portion of the frame construction. The compressible seal member is sufficiently compressible to form a radial seal between and against the frame construction and a surface of a housing when the filter pack is inserted within the housing.

主权项

1. A filter element arrangement comprising:
(a) a media construction having first and second, opposite, ends; a first flow face at the first end; a second flow face at the second end; a plurality of flutes; each of said flutes having a first end adjacent to said first flow face and a second end adjacent to said second flow face;
(i) selected one of said flutes being open at said first end and closed at said second end; and selected ones of said flutes being closed at said first end and open at said second end;(ii) said media construction having a cross-section including a pair of curved ends joined by a pair of segments; and (b) a sealing system including a frame construction and a seal member;
(i) the frame construction extending around a periphery of the media construction;(ii) the seal member including pair of curved ends joined by a pair of segments and being positioned on the frame construction.(iii) the seal member being oriented to form a releasable peripherally directed seal with a housing sealing surface, as a result of insertion of the filter element arrangement into sealing engagement with the housing sealing surface.
