  • Blow out resistant filter
    Patent number: 5049172
    Abstract: A filter for filtering gases, such as air, using a backing material on the downstream side of a filter media to prevent the filter media from blowing out, or separating from a frame. The backing material is congruent in shape with the filter media, so that if the filter media is pleated, the backing material is pleated in a like shape. The backing material may extend to an upstream side of said filter media so as to further aid in blow out resistance.
