Abstract

PURPOSE: To improve the efficiency of the fan and to lower the noise level, by fixing stator blades to the inner wall surface of a fan casing located on the side of a bell mouth in the manner that they face the outer circumference of a vane wheel.
CONSTITUTION: The stator blades 21 are fixed to the inner wall surface of the fan casing 5 located on the side of a bell mouth 7, in the manner that they face the outer circumference of a vane wheel 1. With such an arrangement, the amount of gas introduced again from the back of bell mouth 7 into the vane wheel 1 can be reduced extremely since the gas discharged from vanes 4 is driven radially outward by stator blades 21. Therefore, it is enabled to improve the efficiency of the fan and to lower the noise level.
