Rainbowair Activator 250 Series II — Ozone Generator | 2,500 Sq Ft

Rainbowair Activator 250 Series II — Professional Ozone Generator for Areas Up to 2,500 Sq Ft

The Rainbowair Activator line has been the go-to ozone generator for property restoration professionals for decades. The 250 Series II is the entry point: 2,500 mg/hr of ozone output, built on the same industrial chassis as the larger Activator models, and proven across thousands of restoration, hospitality, and property management deployments.

Where cheaper units fail — inconsistent output, plates that corrode in months, timers that fail mid-treatment — the Activator 250 keeps running shift after shift. That reliability isn’t accidental. The Series II design uses ceramic ozone plates with aluminum construction, the same bill of materials as the Activator 1000 and 2000.

Corona Discharge Ozone at Commercial Scale

The Activator 250 uses high-voltage corona discharge to split O₂ molecules and produce ozone at a consistent 2,500 mg/hr rate. The ozone disperses through the treatment space, oxidizing and destroying odor compounds — smoke, pet, mildew, chemicals — embedded in surfaces, fabrics, HVAC systems, and wall cavities. Unlike enzyme treatments or deodorizers, ozone reaches areas you can’t physically clean.

Treatment requires unoccupied space. Clear the area of people, pets, and houseplants before operation. Ventilate fully before re-entry.

Who Uses the Activator 250

Property restoration companies use it as their standard single-room tool for smoke and water damage jobs — powerful enough to treat a 2,500 sq ft floor in one pass, compact enough to carry to every room. Hotel and vacation rental managers use it between guest stays to eliminate persistent odors that housekeeping can’t reach. Auto detailers use it for vehicle interiors with the optional Single Auto Accessory Kit. Property investors use it to turn around problem units before sale or re-lease.

Maintenance kit (RAKIT52-II) available separately. 2-year limited warranty. Made in the USA by Rainbowair/Queenaire Technologies.
