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.
- Model V fans use a direct drive motor, which has no belts to replace or pulleys to adjust for simplified operation.
- Model VB fans use a belt drive motor, which includes a variable pitch drive for precise speed control and quieter operation.
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.
