As a result, the fan impeller rotates forward, just like a jet aircraft does, due to the high-speed jet emitted from the back of the jet unit. Nominal working 40-110 PSI. The propeller is precisely counterbalanced by moving away debris from the end of the vanes. High performance, high grade, high pressure gasket for extended use.
Vane blades to avoid turbulences that smooth the airflow and increase efficiency. A robust aluminium casting casing and a fan impeller made of aluminium casting make up the assembly. Blower impeller and concave spindle are the only parts that rotate. There is no torsional moment on the fan as it does not transfer force to the impeller as is normally the case with fanafts.
Pneumatic nozzles power the fan impeller. An impeller has a boss and four vanes that generate sufficient stationary force to surmount the drag of the system to be aired. Two of the four shovels have nozzle exhausts. Both the other buckets have good profile cross-sections for a better inductive relationship.
Enclosure fitted with stator paddles for improved effectiveness. Paddles neutralise the spinning motion of the rotor blade and direct the stream of compressed gas in an axially directed manner. Enclosure has a sleek intake port for more CFM, higher efficiencies and lower sound levels.
