The Aqua Ultraviolet Viper Series is 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. Its compact body design has a small footprint, making it easy to handle, install and maintain. The 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. It will help clear your water in 3 to 5 days sometimes overnight and keep it that way.
All Vipers come complete with Unit, Transformer and flow switch. Click Here for Aqua Ultraviolet Viper UV Sterilizer Manual
