RGF’s UV/O3 Advanced Chambers are a combination of ozone and ultraviolet light in one easy-to-service chamber. The combination of the UV and ozone produces a hydroxyl radical which is an extremely effective oxidizer. With optional service unions on each end, a cloth swab can be easily passed through the quartz tube for cleaning. Two sizes to choose from to fit your application. Both models require an Ozone Venturi to operate. Recommended for storage tanks up to 850 gallons.
