Watts Water R14WM reverse osmosis (RO) systems are constructed from the toughest of materials and provide permate rates from 1800 to 5400 gallons per day. Watts uses stainless steel pumps and mounting panels to ensure system longeivity. RO Membrane housings are constructed of fiberglass reinforced plastic for superior chemical resistance. Our conservative design approach ensures that the RO membranes are operated according to the membrane manufacturer's guidelines. This reduces the potential for membrane fouling that often occurs on systems with undersized pumps. Stainless steel wall mount frame. Fiberglass reinforced membrane housings. 4.5" x 10" Pre-filter.
