    The Legacy® QuadSEAL ™ is a molded, foamed, polyurethane frame filter with quad-seal integrated gasketing that utilizes LoadTech® proprietary media. This filter is manufactured with proprietary E-Pleat® technology that allows for even loading and complete utilization of media. The filters consist of an embossed, pleated synthetic media pack contained in cell sides made of molded, foamed polyurethane with an integrated gasket. Media is made of a continuous sheet of blue-tinted, 100-percent synthetic fiber that is water-resistant, durable, and resistant to tearing or abrasion.
    The QuadSEAL integrated gasket provides a dual-ribbed, four-way filter seal to prevent bypass. The polyurethane frame is moisture, chemical, and corrosion resistant. The media pack is 100-percent potted in the foamed, polyurethane frame, eliminating bypass. No additional sealants or adhesives are necessary.
