GrowoniX High Flow RO Water Filtration System GX400 HF

Growonix GX400 Reverse Osmosis System for 400 GPD

The Growonix GX400-HF runs two GXM-200-HF high flow membranes to produce 400 GPD at 17 GPH and a 2:1 ratio. Those membranes hold a consistent 97% rejection to keep your ppm low. It is wrapped in the GX Series patented bracketing on an electrogalvanized, powder-coated steel frame for corrosion resistance. A 2" liquid-filled stainless steel gauge reads input pressure at a glance. Clear pre-filter housings let you watch the filters load. Most growers swap them once they turn coconut brown.

Less Water Waste and Easy Upkeep

The 2:1 ratio uses about half the water of traditional RO systems. A manual flush valve purges salts off the membrane, which adds real life to it. The auto shutoff valve closes the system when you run a float valve or faucet. It carries a green coconut carbon cartridge rated for 8,000 gallons of chlorine reduction and a washable, reusable pleated sediment filter. It runs on as little as 20 PSI of feed pressure. Higher TDS or colder water will lower production.

Key Features

• 400 GPD output: Dual GXM-200-HF high flow membranes flow 17 gallons per hour at a 2:1 ratio.
• 97% rejection: Consistent rejection brings your feed-water ppm down.
• Half the water waste: The 2:1 ratio uses about 50% less water than traditional RO systems.
• Green coconut carbon: Cartridge rated for 8,000 gallons of chlorine reduction.
• Washable sediment filter: High-flow pleated element rinses clean and reinstalls.
• Electrogalvanized steel frame: Powder-coated for corrosion resistance and component protection.
• Liquid-filled gauge: 2" stainless steel pressure gauge for accurate input monitoring.
• Manual flush valve: Purges salts off the membrane to extend its life.
• Auto shutoff valve: Positive shutoff when used with a float valve or faucet.
• Clear pre-filter housings: See when filters load; wall-mountable with 1.5" roll-away casters.
