ABSTRACT:
A turbo blower, include an air hood provided with an air inlet and a turbine disposed within the air hood driven and rotated by a motor. The turbine consists of a plurality of guide vanes fitted between a circular base plate and a top plate. The turbo blower is characterized by the height of each of the guide vanes, commencing at a vane front end close to a center of the base plate, gradually decreases to a relatively lower point at a middle section of the guide vane, and the height of each of the guide vanes, commencing at the relatively lower point, gradually increases to a vane rear end, thereby forming a curved shape. The turbo blower is able to automatically decrease power consumption when the air inlet end or the air outlet end is obstructed, thereby reducing motor load.
