Abstract:
A single suction type centrifugal fan includes a casing, an impeller, and a main plate. The casing includes a side plate and a motor fixing side plate, and the side plate and the motor fixing side plate are arranged in parallel. A rectifying plate is provided between the motor fixing side plate and the main plate, and the rectifying plate is formed from an inclined surface in which an area of a cross section orthogonal to a rotation shaft is reduced toward the impeller around the rotation shaft of a motor. A first rectifying plate diameter at another side of the rectifying plate closer to the impeller is smaller than an impeller diameter of the impeller.
