<p>PURPOSE:To provide a centrifugal blower for restraining reduction of the blowing efficiency and rise of produced sound pressure level respectively due to the deviation between the design blade output angle and proper outlet angle when an impeller is used at a motional point under high static pressure requirement different from a design motional point. CONSTITUTION:An elastic blade plate 7 made of a material having elastic modulus smaller than that of a blade plate 6 at the blade outlet side of the blade plate 6 of an impeller 5 is provided.</p> |
