Aqua Flo's patented UVB system is designed to provide disinfected water at a flow rate of 2 GPM. UVB systems are ideally suited for installation under kitchen sinks or on office water coolers, water vending machines, boats, and recreation vehicles. In addition to disinfection, this all-in-one system filters water through the 0.5 micron Extended Pass Carbon Block (EPCB) filter. The double and triple models provide you with additional filtration with sediment and activated carbon filters.
