Abstract

The addition of a medial longitudinal score line (hinge point) along the longitudinal channels of the filter frame allows for thinner media and/or collapsing the frame on itself which will reduce scrap, save space and save tremendously on shipping costs. The additional score line can be a cut score, skip score, crush score or liquid line. The collapsed filter frame expands upon sliding into the channels of the filter frame media holder whereby the filter frame expands and widens to fit the filter assembly.
