The Ona Cyclone is a cost-effective, high-quality Ona Gel Distribution System. This portable fan runs very quietly and effectively. Loaded with a 20 liter pail of Ona Gel, it will provide high-volume, high-capacity distribution. Using less power than a light bulb, the Ona Cyclone delivers up to 5,000 sq ft. Fan speed is controlled by a variable high-tech push button switch, so you can adjust the airflow of Ona.
