Product Description
Commercial 5-Stage High-Flow RO Water Purification System (400GPD)
Direct-Drinking Commercial Reverse Osmosis Unit with Real-Time Smart TDS Display & Deep UVC Sterilization (OEM/ODM Factory Supply)
The Viano Commercial 5-Stage RO Water Purification System (WYN-RO400-COM) is a high-capacity, heavy-duty filtration solution engineered specifically for high-demand commercial environments, including offices, restaurants, coffee shops, cafeterias, and commercial kitchens. Delivering a direct drinking flow rate of 400 GPD (gallons per day) without requiring a large pressurized tank, this system combines multi-stage mechanical and carbon pre-filtration with a high-rejection Reverse Osmosis membrane.
Integrated with a smart micro-computer controller, it provides real-time dual TDS (Total Dissolved Solids) monitoring for both inlet and purified water quality on a clear digital screen. A terminal deep UVC LED sterilization chamber guarantees 99.99% pathogen-free, bacteria-safe drinking water at the point of dispense. Supported by a floor-standing/wall-mountable powder-coated steel frame, global B2B distributors and brand owners can access complete OEM/ODM factory customization.
Key Features
  • 5-Stage Deep Filtration Architecture: Combines PP sediment, GAC granular carbon, CTO carbon block, high-rejection RO membrane, and a post-carbon/UVC module to eliminate up to 99% of heavy metals, chlorine, dissolved solids, bacteria, and organic impurities.
  • 400GPD Tankless High-Flow Capacity: Produces up to 400 gallons of purified water per day (~1.05 L/min continuous flow), delivering fresh, direct-drinking water on demand without tank stagnation.
  • Smart Monitoring & Dual TDS Display: Features an intelligent LED control panel that continuously monitors and displays real-time inlet and outlet TDS levels, automatically alerting users to filter replacement schedules and system status.
  • Deep UVC LED Sterilization Module: Equipped with an integrated inline UVC LED module at the final stage, destroying bacteria, viruses, and microbial contaminants without chemicals or heat generation.
  • Heavy-Duty Commercial Frame Structure: Built on a reinforced powder-coated steel mounting chassis for stable floor placement or under-counter integration, protecting internal piping and components from commercial wear.
  • Comprehensive B2B OEM/ODM Customization: Flexible factory manufacturing supporting customizable capacity options (400GPD, 600GPD, 800GPD), customized filter housing sizes (10" or 20" slim/jumbo), custom frame colors, laser-printed logo plates, and regional voltage/plug adapters.
