US 6,517,598 B2 · Filter element having flange and methods

Abstract

A filter element is provided including a media construction including a corrugated sheet secured to a flat sheet rolled into a coiled construction. The filter element includes a mounting flange secured to the coiled construction. The mounting flange projects radially from the outer, annular surface of the coiled construction. The mounting flange defines at least one fastener socket to allow for axial mounting of the filter element into a housing. An air cleaner includes a housing with filter elements, as described herein, operably installed within. Preferably, the filter element is sealed within suitable housings with a seal, such as a radially directed seal. Preferably, the filter element is secured to the housing by axial mounting of the mounting flange to the housing using fasteners. Methods for installing, assembling, using, and servicing are provided herein.
