The Ozone Quantum series produces ozone at 400 g/hr (CD-400F), 800 g/hr (CD-800F) and 1200 g/hr (CD-1200F) at 5% by weight; all systems operate under vacuum, for safety, efficiency and ease of operation. All systems have configurable feed-gas options (integrated oxygen concentrator system is standard), multiple safety features, self-diagnostic switching and robust construction. Proportional ozone output control is standard on all models.
