Abstract

PURPOSE: To provide the same wind feeding performance in both 50Hz and 60Hz areas, by adjusting an opening degree of a communication passage communicating a suction port with a discharge port.
CONSTITUTION: A communication passage 20 is formed on the partition part 19 located between a suction port 14 and a discharge port 15. This passage 20 allows a leak of partial flow from high pressure at the discharge port 15 to the suction port 14. In case of operating a 50Hz designed fan with 60Hz, it can not be fit for use due to extremely high air output and overload of the motor. In such a case, when a closing member 21 is moved so that the passage 20 may be opened, the performance suitable for 60Hz can be obtained.
