Description:
The lightweight, portable Air Mover is available in four models, identified by the diameter of their annular orifices – 2, 3, 6 and 10 inches. Made of galvanized steel and aluminium alloy, the ventilators use compressed air or steam to induce a rapid flow of outside air equal to 10 times its own volume. Pressure sources of upto 100 psig may be used to power the device.
Because the ventilator requires little space, the unit fits into areas too small for motors  and blowers. And the cost is much less than conventional explosion proof motors and blowers.
