BCA Airfoil Fans
BCA AIRFOIL FANS Series 800 is a result of careful design and exhaustive testing. The shape of the airfoil alone required extensive research and series of test work before it was produced. The final product is a wheel with high efficiency, quiet operation and very strong framework.
The airfoil blade incorporates the non-overloading characteristic of the backward-inclined blade with the pressure-producing design of the forward-curve blade. The wheel runs at a slower speed than most airfoils but delivers more air than that of other wheels with similar designs, at the SAME rpm.
Airfoil wheels are inherently strong in construction and can withstand faster speeds. Therefore, a Class 3 wheel design is included. The operating limits of the three classes are as follows:
Class 1 - 11,000 FPM tip wheel speed
For added safety and durability, Class 3 wheel blades have internal reinforcement within the airfoils.
The same common housing for Series 800 is used, which saves cost and lowers inventory investment.
