Sold out
$482.28

The GX series is the top of the line Reverse Osmosis filter offered by Growonix.

Offered in various sizes and flow rates, these units include the highest quality components available and provide the lowest waste water ratio available.

The Growonix GX400 is designed to flow 17 gallons per hour of pure RO water, with an astounding 2:1 ratio. High flow rates and water savings have never before been seen in a package so affordable and durable. Utilizing the most efficient membrane technology in the world, built with dual o-ring fittings, wrapped in our patented GX Series bracketing system, and equipped with a stainless steel liquid filled pressure gauge, the GX400 is a staple in every garden.

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 GX400 can be used with a booster pump, raising the system pressure to 80psi, increasing the gallon per day output.

The strategy behind the GX Series is simple; build 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.
