Flows 8.5 gallons per hour of pure RO water, with an astounding 2:1 ratio Designed to flow 8.5 gallons per hour of pure RO water, with an astounding 2:1 ratio for high flow rates and water savings never before seen in a package so affordable and durable. Utilizing the most efficient membrane technology in the world, built with dual o-ring fittings, and equipped with a steel pressure gauge. The GrowoniX EX200 Systems Feature: High Flow Cold Water membrane 2:1 system ratios - The most efficient in the industry Electrogalvanized powder coated steel brackets One Coconut Carbon filter rated for 8,000 gallons chlorine reduction High Flow pleated sediment filter, completely washable and reusable Auto Shutoff Valve-for positive automatic shutoff when using a float valve No additional pre-filters needed Carbon capacity—8,000 total gallons of chlorine or chloramine removal, or 3,000 gallons of RO water at a 2:1 ratio. *Chloramine removal requires a KDF85 carbon fiber. For those who demand even more performance, the EX200 can be used with a booster pump, raising the system pressure to 80psi, increasing the gallon per day output. For those with tap water that contains chloramines, the EX200 can be upgraded with a KDF/CAT carbon filter.
