Tu-Way Roof Ventilator, Belt Driven
The TWBD roof ventilator is designed for corrosive environments and when temperatures exceed the motor insulation rating. The model TWBD features a reversible impeller design that is equally efficient and moves the same amount of air in either supply or exhaust direction.
Tu-WAY™ fans are designed to allow the hood to be raised for easy access to the impeller. Access doors are standard for maintenance or removal of motor, drives and damper (optional). Reversing the impeller rotation is performed by moving the motor starter switch to the opposite position. This permits the motor to come to a complete stop before restarting in the opposite direction.
