Sand filters are one of the most desirable methods to keep pool water clear and sparkling. Not only does the all-natural, inexpensive sand do an excellent job of filtering the water, it needs replacement only once every five years, making sand filter the easiest maintenance filtration option on the market. Saltwater systems with E.C.O. (electro catalytic oxidation) are known for their ability to keep pool water clean and safe, while eliminating the harshness of traditional packaged chlorine. Intex has combined these two excellent systems into one product, providing above ground pool owners with ONE low cost, low maintenance system that will keep pools clean, safe, and comfortable for swimmers. Both systems are controlled automatically with one 24-hour timer to make daily operation care-free!• Designed for use with Above Ground Pools from 4,800 to 15,000 Gallon Capacity. • 110-120V with GFCI (Ground Fault Circuit Interrupter). • 16 and #34; tank diameter. 0.95 hp. motor. • Pump flow rate 2,650 gph.
