An axial flow fan characterized in that a conical flow path is uniformly provided over the entire circumference, and mounting flanges are provided at both the air inlet and outlet of the wind tunnel. (2) Utility model registration claim No. 1 characterized in that the mounting flange is provided only on the air outlet side.
Axial flow fan described in (1). (3) The outer diameter of the wind tunnel at the location where the mounting flange provided on the air outlet side is installed should be the dimension that reaches outside the line connecting the outer periphery of the mounting flange, and the outer diameter dimension of the wind tunnel on the suction port side should be the dimension where the mounting flange is installed. The axial flow fan according to claim (1) of the utility model registration, characterized in that the axial flow fan is provided with substantially the same dimensions as a line connecting the outer peripheries of the flanges.
