Designed to flow up to 33 GPH (Gallons Per Hour) of almost 0 ppm purified water—that’s 800 GPD. Shipped with a 2:1 system ratio (for feed water over 300ppm), along with an additional flow restrictor for a 1:1 system ratio (with feed water under 300ppm). The magic behind the EX800-Tall is our new 3” high flow membrane with 96% rejection. We put the same R&D that delivered our unmatchable GXM-200-HF and GXM-1000-HF membranes into a smaller, fatter, more fun package—and walla!

Tall means more carbon and sediment filtration—17,000 total gallons worth of carbon filtration! That’s 5,700 gallons of pure RO at a 2:1 ratio, and 8,500 gallons of pure RO water at a 1:1 ratio. Dual stainless-steel liquid-filled pressure gauges to allow monitoring of the incoming water pressure, as well as any pressure drop between the pre-filters. The entire system is wrapped in a freshly designed electro galvanized powder-coated steel chassis with a removable front face (for easy servicing). Backside panel has standard holes for wall mounting, and of course, all attaching bolts are stainless-steel, for corrosion resistance. Two black oxide stainless bolts on the top panel allow for simple mounting of a UV-1530 or UV-6010 Ultraviolet filter. The top panel also includes a relief for easy carrying.

The EX800-Tall comes standard with a membrane flush valve, to purge out pollutants that can cause clogging and pre-mature fouling. The high flow fast-action auto shut-off valve allows for system shutdown when paired with an optional float valve. All fittings are quick-connect, dual o-ring American made, as well as John Guest. The quick-change membrane housing allows for membrane replacements without disconnecting any hoses or tubing—just spin it off and pop a new one in! It’s affordable, durable, and packed with features you would expect on light commercial systems. Out-flowing all other RO’s in the same class, with the same quality you would expect from a GrowoniX product. No little RO on the planet can match the EX800-Tall.
