Non-cylinderical filter elements; and, methods

摘要

A filter element that has at least two, planar, non-curved filtration panels. In a preferred embodiment, the filter element has three panels, providing a generally triangular filter element. The outlet aperture, from the filter element, generally follows the configuration of the filter. That is, a filter element having three filtration panels will have a generally three-sided outlet aperture. The outlet aperture preferably is not a true polygon, but rather, includes rounded or curved sides and/or corners. The filter element includes an outlet sealing configuration that may provide both axial and radial sealing to outlet ductwork.

1. A filter element comprising:
(a) filter media; (b) support structure supporting the filter media;
(i) the support structure and media defining an open filter interior;(ii) the support structure defining a first closed end; and,(iii) the support structure defining a second end opposite the first end; the second end having a non-circular outlet aperture therethrough in communication with the open filter interior; (c) a non-circular trough in the second end of the support structure and in extension around the non-circular outlet aperture in the second end of the support structure; and, (d) a non-circular seal member positioned recessed in the non-circular trough from at least one side of the trough.
