Model V upblast roof fans discharge warm, humid air out of the building. Whether it’s exhausting hot air or moving stagnant air, roof-mounted Model V fans will improve your building’s ventilation. The upblast fan exhausts air at a high velocity, pushing exhaust air far away from the building to prevent contaminate re-entry. Internal butterfly dampers shut automatically when the fan is not activated. The high velocity exhaust airstream holds the dampers open preventing the entrance of rain or snow.
When the motor power is turned off, the dampers close to provide a complete weather seal. A rain runoff trough is located below the damper shafts to provide drainage to the outside resulting in weather-tight construction.
