Paramount Clear O3 Ozone System 50K Gallons 004-402-3880-00. Use of ozone reduces the demand for pool chemicals by up to 70% and allows the chlorine in the pool to work more effectively as a disinfectant. The patent pending Clear O3 consists of an extruded aluminum body with fiber filled resin end caps. It has been engineered to survive in the pool equipment environment. The cylindrical chamber of the Paramount ClearO3 system is optimized for maximum ozone generation and is completely sealed to minimize ozone leakage making the unit both powerful and safe around swimming pools. Radiant heat ribs dissipate heat to maintain ozone output at peak operating temperatures and the side panel is removable, making maintenance and bulb replacement easy.
