Everything is easy when you’re working with a Pro. Because the Pro Series High-Rate Sand Filter System from Hayward offers advanced full-flow technology that results in sparkling pure water, energy efficient operation, and good, clean fun for the entire family. It’s also simple to operate. The Pro Series six-position Vari-Flo control valve lets you quickly and effortlessly select the desired pool filter function with just a gentle twist of the wrist. Plus, its rugged, corrosion-proof tank construction protects these liquid assets for a long, long time. All of which makes the Pro Series filter a crystal clear choice. Perflex Extended-Cycle DE filter series cleans pools fast — removing particles as small as one micron the first time through. That’s because Perflex incorporates a patented Flex-Tube design that works in combination with DE (diatomaceous earth) filter powder to produce the clearest, most sparkling water possible. The exclusive Perflex Extended-Cycle gives you long filter cycles between cleaning — up to eight weeks depending on pool size and use. Because the same filter powder is used over and over again, Perflex is a real work saver. And, it only takes minutes to extend the cycle. Hayward Star-Clear cartridge filters provide sparkling pure water for a wide range of pool sizes and types. From spas, hot tubs and above-ground pools, to large in-ground pools, Star-Clear filters deliver full-size filter system performance — in an easy to afford package. Star-Clear filters feature a heavy-duty cartridge element engineered of high-quality reinforced polyester for maximum efficiency, easier cleaning and longer life. A single locking knob provides easy access to the cartridge element and securely fastens the filter head to the filter tank — eliminating clamps or bolts.
