Centrifugal Belt-Drive Downblast Exhaust Ventilators
- Centrifugal Belt-Drive Downblast Exhaust Ventilators
- Designed to meet the general clean air exhaust requirements for industrial and commercial buildings. Rugged and reliable construction makes fan capable of withstanding severe exhaust conditions. Spun aluminum construction features a fully rolled windband bead for increased stability and easy transport. Fresh outside air is drawn in under the motor cover to maximize motor life. Drive frame is internally isolated from the rest of the unit through use of neoprene isolators for long life and quiet operation; no steel-to-steel contact. Motors, sheaves, and belts are packed separately when complete, unassembled ventilator with drive package is ordered.
- UL and C-UL Listed.
