Rainbowair Activator 1000 Series II — Ozone Generator | 10,000 Sq Ft

Rainbowair Activator 1000 Series II — Industrial Ozone Generator for Large Commercial Spaces Up to 10,000 Sq Ft When the job is a full commercial building floor, a large hotel wing, or a warehouse, the Activator 1000 is the standard tool. At 10,000 mg/hr and a rated coverage area of 10,000 sq ft, it's the unit most restoration companies keep on every truck alongside the 250 or 500 for single-room work. Built on the same Series II platform as the 250 and 500, the 1000 adds a reinforced aluminum chassis, a higher-capacity corona discharge array, and a heavy-duty 0–12 hour timer rated for daily commercial use. This is not a consumer-grade machine dressed up in a commercial SKU — it's the same unit that's been in active restoration fleets for 20+ years. 10,000 mg/hr Corona Discharge System Four ceramic ozone plates operate in parallel inside the Activator 1000's array, producing consistent output across the full treatment session. The higher plate count doesn't just mean more ozone — it means the output curve stays flat rather than declining mid-session as a single-plate unit's temperature rises. For long treatment cycles on large spaces, that consistency matters. Requires unoccupied space. At this output level, allow 45–90 minutes of active ventilation (fans + open windows) before re-entry.
