Clack Corporation introduces its new line of 4.5-inch (114.3 mm) diameter dual-gradient, melt-blown sediment filters. Dual gradient depth filtration is accomplished with state-of-the-art production equipment and patented ‘take-off’ design. This design creates two distinct filtration zones to maximize dirt-holding capacity and minimize change-outs. Larger sediment particles are trapped and filtered out in the first zone; smaller particles are trapped in the second zone. The filters are made of polypropylene resin meeting FDA regulation 21CFR177.1520. No binders, lubricants or anti-static agents are used in the manufacturing process. The filters have been tested and certified under NSF/ANSI Standard 42 for material requirements only. They are available in 25/01, 25/05 and 50/25 micron ratings and will fit most standard Big Blue and Big Clear filter housings. Private labeling is available.
