Designed to flow 25 GPH (Gallons Per Hour) of pure RO water. Utilizing the best membrane technology in the world, mounted on locking casters, and wrapped in our EX Series patented bracketing system; our EX600 will change the way you look at RO. A pair of liquid-filled stainless steel pressure gauges tell you 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. For those who demand even more performance, the EX600 can be used with a BP-600 pressure-boosting pump to dramatically increase GPD output.
