Abstract

This article is a sirocco fan in which a plurality of blades are arranged in a cylindrical shape. As shown in the reference cross-sectional view A-A, the side on the intake port side of the blade has a curved shape that is recessed, so that the sirocco fan can be made smaller and the air volume can be increased.
