Jet Fans

A jet fan drives a tight column of air down a tunnel, tank or vault using compressed air jets on the blades instead of a motor. The Texas Pneumatic jet fan is a four-blade vane axial unit in a rugged cast-aluminum housing with a cast-aluminum blade; air jets on the trailing edge of two of the four blades spin the wheel, so the shaft transmits no power and carries no torque. Only the shaft, bearings and blade rotate. Airfoil blade sections and bolt-on guide vanes take the swirl out of the discharge and raise efficiency, and performance was measured at an independent lab to AMCA Standard 210. It runs as a ventilation blower or as an exhauster. Compare tornado blowers and venturi air movers, or see the whole Texas Pneumatic jet fan line.
