Jet fans

Jet Fans

The Airblast Jet Fan is a four-bladed vaneaxial fan which operates through a highvelocity jet of compressed air which is ejected from the trailing edge of the blade. This results in the forward rotation of the fan wheel just like a jet plane is pushed forward by the high-velocity jet ejected from the rear of the jet engine.

Features

The unit consists of a rugged cast-aluminum housing and a cast-aluminum fan
The hollow shaft and the fan wheel are the only rotating parts. However, there is no torque on the shaft, as it does not transmit any power to the fan wheel, as fan shafts normally The compressed air jets drive the fan wheel.
The fan wheel has a hub and four blades, producing adequate static pressure to overcome the resistance of the system to be ventilated.
Only two of the four blades have jet The two other blades have good airfoil cross sections for a better induction ratio.
The housing is equipped with guide vanes for better The vanes will neutralize the air spin past the blades and guide the air flow into an axial direction.
The housing has a smooth inlet bell for increased CFM, higher efficiency, and lower noise
It’s performance was tested at an independent test lab to the AMCA Standard 210
Shipped with grounding cable for safety and crowfoot
