Abstract
A centrifugal blower wheel having an indivisible prime number of peripherally spaced blades projecting upwardly from the top surface of a generally annular-shaped base plate. Each blade includes a tapered portion extending along an inside edge of the blade to approximately 1/3 to 1/2 the length of the blade. A hub is centrally located on the top surface of the base plate and surrounded by the inside edges of the blades, the hub curving upwardly from the top surface of the base plate to form a smoothly contoured curve.
