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 exhaustible output by monitoring the exhaust air for odors. Warning: For commercial use only in unoccupied areas.
