Model VBO-HV Heat and Smoke Fans are designed to meet the normal ventilation needs of many industries, as well as the removal of smoke and fumes during a fire emergency. 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 VBO-HV could be operated at these elevated temperatures without failure.
