Abstract

PURPOSE: To provide an ventilating apparatus for duct, which is capable of changing its ventilating direction and can be fitted in place with high degree of freedom.
CONSTITUTION: A centrigugal fan is incorporated in a box-like case 6 to cause forced ventilation from inlet ports formed in flat surfaces of case 6 to outlet 19 formed in a side wall of the case 6. In such an arrangement, a first inlet port 8 is formed in one of opposing surfaces of case 6 whereas a second inlet port 9 is formed in the other surface. The fan, on the other hand, is provided with double-vane type blades 11 corresponding to the first and the second inlet ports 8, 9. Further, case 6 is provided with brackets 13 which enable the first and the second inlet ports 8, 9 to selectively oppose the fixture wall.
