The Viper Series UVs are ideal for large commercial or residential ponds, aquariums, and water features. The specially designed 4-inch 400 Watt lamps disinfect faster and have greater cell penetration capability. The compact body design has a small footprint making it easy to handle, install and maintain. Vipers are engineered to accommodate extreme flow rates; minimum water flows must be maintained at 95 GPM. A flow switch, provided, shuts the unit off if flows fall below 95 GPM. Aqua Ultraviolet UVs will clear your water in 3 to 5 days sometimes overnight and keep it that way. Performance is guaranteed when sized, installed and operated according to our instructions.
