Alu 25 Dia 26.6 H Roof Fan w.Motor MPN:2RB63

This ventilator is designed to meet the general clean air exhaust requirements for industrial and commercial buildings. The rugged and reliable spun aluminum construction makes the fan capable of withstanding severe exhaust conditions. The fully rolled windband bead provides increased stability and easy transport. Fresh outside air is drawn in under the motor cover to maximize motor life. The drive frame is internally isolated from the rest of the unit through the use of neoprene isolators, for long life and quiet operation - no steel-to-steel contact.
