ABSTRACT:
A radial air filter is pleated in the horizontal direction rather than the vertical direction so as to have increased capacity and efficiency with reduced air flow restriction. Preferably, the pleats have a parabolic cross section wherein the panels of the pleats form legs of parabolas with the legs being joined by arcuate peaks and valleys.
