気扇。 A duct connecting body is provided at the side exhaust port of the main body frame in which the blower is installed, and two types of ducts having a common outer diameter and different inner diameters can be selected and connected to the duct connecting body. The duct connecting body is composed of an outer cylinder whose inner diameter is approximately the same as the outer diameter of the duct, an inner cylinder whose outer diameter is smaller than the minimum inner diameter of the duct, and a plurality of ribs connecting them. A ventilation fan for a duct, characterized in that a shutter is disposed inward from the inner peripheral surface of the inner cylinder, and the exhaust port of the main body frame is formed to have a diameter substantially equal to the inner diameter of the outer cylinder.
