Abstract (en)
A fan (1) includes an impeller (3) rotated about the vertically extending central axis (C), a motor (5) rotating the impeller, a motor housing (4) housing the motor (5), and a fan casing (2) disposed radially outside the motor housing (4) to form a flow passage (FL) in a gap therebetween. A plurality of first stationary blades (412) that axially extend and a second stationary blade (413) that axially extends are disposed radially outside the motor housing (4). The first stationary blades (412) are arranged in a circumferential direction. The second stationary blade (413) is disposed between the first stationary blades (412) adjacent to each other in the circumferential direction. An upper end of the second stationary blade (413) is disposed further to a lower side than upper ends of the first stationary blades (412) and further to an upper side than lower ends of the first stationary blades (412).
