Growonix EX400 Tall High Flow Reverse Osmosis System - 14 x 7 x 29-in - 2 Membranes

Cleaner Feed Water for Hydroponic Reservoirs - 14 x 7 x 29 in

Dissolved solids and chlorine in tap water can upset nutrient balance and shorten equipment life in hydroponic systems. The Growonix EX400 Tall high flow reverse osmosis system filters feed water through a carbon filter and two polyamide membranes, with a nominal salt rejection of 96%. A manual membrane flush valve lets you purge buildup from the membranes between runs.

This single unit suits growers who want a wall or frame mounted RO system for a regular indoor setup. It stands 29 in tall, so check your mounting space before ordering. A booster pump upgrade is available for low pressure feed supplies.

Key Features & Benefits

• Two polyamide membranes — give the system its high flow capacity and 96% nominal salt rejection.
• Membrane flush valve — lets you clean the membranes by hand to limit buildup.
• Carbon filter — reduces chlorine in the feed water before it reaches the membranes.
• Powder coated steel bracket — holds the housings in a rigid frame.
• 3/8-in RO quick connect feed — makes the feed hookup simple.

Frequently Asked Questions

Q: What feed pressure does it need?
A: The listed feed pressure range is 40 to 80 psi. A booster pump upgrade, model BP-1530, is available for supplies that fall short.

Q: Can it handle chlorinated water?
A: The carbon filter reduces chlorine before the membranes. The listed chlorine tolerance at the membrane is below 0.1 mg/L, so the carbon stage must stay in good condition.

Q: What does nominal salt rejection mean?
A: It is the share of dissolved salts the membrane is rated to remove under standard test conditions. This system is rated at 96%.

Q: How do I clean the membranes?
A: Open the membrane flush valve to purge buildup from the membranes. Follow the user manual for the flush procedure.

Q: What size is the unit?
A: It measures 14 in long, 7 in wide and 29 in tall.

Q: What water limits apply?
A: Feed water should stay below 2000 ppm TDS and below 1 NTU turbidity. Continuous pH should stay between 5 and 11.
