Abstract

PURPOSE: To improve the ventilation efficiency by increasing the air quantity and vacuum degree by arranging an inducer for smoothly feeding air into an impeller on the inner peripheral part of the impeller and inclining each blade of the inducer and impeller.
CONSTITUTION: A diffuser consisting of a casing 21 and an air guide 26 is arranged on the outer periphery of a centrifugal impeller 24 having a plurality of blades 25. In this case, an inducer 24 which gradually changes the flow direc tion from the axial direction to the radial direction and sends air into the impel ler 24 is installed on the inner peripheral part of the impeller 24. Further, a plurality of blades 36 of the inducer 34 are inclined forward so as to introduce air. Further, each blade of the impeller 24 is inclined in accordance with the inclination of each blade 36 of the inducer 34. Then, the impeller 24 as centrifu gal fan is provided with a function as mixed flow fan by the inducer 34.
