Ozone safely alters the molecular structure of offensive micro-organisms, to eliminate odor. The Uvonair® CD-1000 ozone generator will treat all odors being exhausted by a 10 in (25 cm) ventilation system under most circumstances. The CD-1000-2 is intended for a room size of 40, 000 cu. ft. (1200 m3). Installs into other size ducts with adapters. Set the Adjust-A-Wingble output by monitoring the exhaustible output by monitoring the exhaust air for odors. Warning: For commercial use only in unoccupied areas.
