Graver Technologies’ CPL series filters utilize pleated element design to provide maximum filtration area in a compact filter assembly, and assure efficient filtration with long element life and low pressure loss. Housings are available in carbon steel, 304 and 316 Stainless Steel, designed and constructed in accordance with ASME Code Section VIII Division I requirements and available with "U" Stamp registration and certification. The element design and construction together offers positive gasket sealing to prevent by-pass of unfiltered liquids. Most housings employ only one filter element, and a maximum of three for the larger housings designed for higher flow rates, to permit quick and simple element change-outs.
