The GX1000 is designed to flow 42 gallons per hour of pure RO water with an astounding 1:1 ratio – High flow rates and water savings never before seen in a package so affordable and durable. Utilizing the best membrane technology in the world, mounted on locking casters, and wrapped in our GX Series patented bracketing system, our premier flagship is a mobile powerhouse. A pair of liquid-filled stainless-steel pressure gauges informs when it’s time to change the pre-filters. A manual flush valve allows you to clean the membrane, purging out pollutants that could otherwise add buildup to the system. Flushing adds considerable life to the membrane as well. For those who demand even more performance, the GX1000HF can be used with a booster pump, raising the system pressure to 150 psi, doubling the gallon per day output. The strategy behind the GX Series is simply to make the highest quality, most efficient water filter, tuned specifically to meet the rigors of the industry. Each filter system is designed, hand built, and tested right here in the United States, using American made, top-of-the-line fittings and tubing. All components are housed in steel powder-coated brackets fabricated in sunny Los Angeles, California. System ratio and flow rate is dependent on feed water temperature and pressure. See pictures for flow rate performance. System ratio is user tunable (additional accessories needed). No guarantee on system ratio, membrane percent rejection, or flow rate as feed water chemistries and conditions are vastly variable. Returns are subject to 15% restocking fee and original shipping costs.
