Ozone safely alters the molecular structure of offensive micro-organisms to eliminate odor. The Uvonair CD-1200 ozone generator will treat all odors being exhausted by a 12 in (30 cm) ventilation system under most circumstances. Intended for rooms up to 100,000 cu ft (3000 m³). Installs into other size ducts with adapters. Set the adjustable output by monitoring the exhaust air for odors. Warning: For commercial use only in unoccupied areas.
