Provided is a once through fan in which a plurality of impellers, comprising a plurality of blades disposed in a cylindrical shape, are provided connected in the axial direction. The impellers comprise a circular or disk shaped reinforcement plate having an outer diameter smaller than the diameter of the inner end part of the plurality of blades disposed in a cylindrical shape, and a plurality of projections formed so as to project inward in the radial direction of the cylindrical shape from a portion of the inner end part of each of the blades. The blades, the projections and the reinforcement plate are formed integrally so that the reinforcement plate connects, via the respective projections, to the inner end parts of each of the blades.
