Abstract

A filter element includes support grid secured about its periphery edges to a periphery frame member. A pleated filter media is secured to the frame member and is sized and positioned to fully cover the filter fluid aperture. The support grid is positioned such that it is effective in providing support to the filter media against fluid forces. At least one elongated comb member is provided and includes a plurality of spaced tapered teeth protruding outwards towards the filter media. The teeth are sized and spaced to be received into at least a portion of grooves present between the pleats of the filter media. The teeth of the comb member are sized and spaced to regulate filter media pleat separation and spacing.
