Model VBO-HV upblast fan

Model VBO-HV Heat and Smoke Fans provide day-to-day industrial ventilation as well as smoke and fume removal during a fire. These high volume, high velocity exhausters are the ideal choice for locations where reliable ventilation is required.

Engineered to meet the high temperature requirements of the Uniform Fire Code of 1000°F for a minimum of 15 minutes, and the IRI requirements of 500°F for a minimum of 4 hours. Tests were conducted by an independent testing organization and witnessed by UL engineers and were tested in accordance with UL smoke control systems standards. The test conclusively proved that the Model VBO-HV could be operated at these elevated temperatures without failure.
