Abstract
A motor-fan unit includes an end plate assembly, a motor assembly supported by the end plate assembly, and a shaft rotated by the motor assembly and extending through the end plate assembly. The fan assembly further includes a discharge shell, a tapered stationary fan which has a concave underside, and a rotating fan secured to the rotatable shaft and disposed between the discharge shell and the stationary fan. The tapered stationary fan includes a fan side which is substantially parallel and aligned with the frusto-conical shape of the fan disc of the rotating fan. A tapered fan shell is supported by the discharge shell and held in place by the stationary fan. A fan shroud secures the stationary fan and the fan shell to the discharge shell to prevent damage to a rotating fan secured to the shaft and positioned between the fan shroud and the stationary fan.
