Pleated media for a conical shaped filter element

Abstract

A frusto-conical filter includes at least one layer of a filtering material, wherein one or more layers of the at least one layer of a filtering material comprises a plurality of pleats. Each of the pleats has a center axis which essentially maintains a constant distance from the center axis of its adjoining pleats. The media filter has a first end and a second end, the second end being spaced apart from the first end, and one of the first and second ends is larger than the other of the first and second ends. A method of making this media involves cutting out a frusto-conical section from a generically shaped media and aligning it in such a way as to maintain the constant distance of the pleats from the adjacent pleats.
