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 (98.5% rejection), 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メ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 150psi, doubling the gallon per day output.
