400 GPD Commercial Reverse Osmosis (RO) System – 5-Stage High-Flow Water Purifier with Heavy-Duty Booster Pump & Direct Flow Technology
High-Performance Water for Commercial Success
The 400 GPD RO System is built for environments where downtime is not an option. From busy restaurants in Colombo to rural schools in the dry zone, this system provides the volume needed for drinking, large-scale cooking, and high-end coffee brewing without waiting for a tank to refill. Its Direct Flow technology ensures that every drop is freshly filtered the moment you turn on the faucet.
Key Features & Benefits:
-
5-Stage Industrial Purification:
-
20-Inch Sediment Filter: A large-capacity pre-filter that handles heavy sediment loads and protects the system from clogging.
-
GAC & CTO Carbon Stages: Dual carbon filtration to eliminate high levels of chlorine, organic chemicals, and unpleasant odors.
-
High-Flux 400 GPD Membrane: A single, powerful TFC membrane (or dual 200 GPD setup) that acts as a total barrier against dissolved salts (TDS), bacteria, and viruses.
-
Post-Carbon Polishing: Refines the final taste for a premium “bottled water” experience.
-
-
Ultra-Quiet Booster Pump: The integrated heavy-duty pump is designed for continuous operation, providing the high pressure required for high-rejection rates (98%+ TDS removal) even in low-pressure municipal or well-water areas.
-
Eco-Efficient Direct Flow: Unlike standard ROs, this high-flow system can be used without a storage tank, saving 70% of under-counter space and eliminating the risk of secondary bacterial growth inside a tank.
-
Heavy-Duty Stand Frame: The entire system is mounted on a powder-coated steel or stainless steel stand for easy maintenance, stability, and wall-mounting options.
-
Smart Monitoring: Includes a built-in pressure gauge to monitor filter health and automatic shut-off switches to protect the pump from running dry.
Typical Applications in Sri Lanka:
-
Restaurants & Hotels: Supplying large volumes of water for cooking, beverage stations, and ice machines.
-
Large Offices & Factories: Providing an unlimited supply of pure drinking water for over 50 employees.
-
Hospitals & Laboratories: High-purity water for sensitive equipment and sterilization processes.
-
Agriculture & Hydroponics: Essential for growers who require low-TDS water for specialized plant nutrition.
