Abstract
A blower having a turbo fan is installed in a scroll housing with a cutoff. The cutoff has an inclination angle of approximately 50 to 80°, so that it is possible to draw in an increased amount of air while reducing the flow resistance of air. Accordingly, blowing efficiency is improved while simultaneously reducing the generation of noise and vibration.
