PROBLEM TO BE SOLVED: To materialize a small size, low noise pipe fan capable of generating high air flow and static pressure with a little electric power consumption. SOLUTION: Air on a room side is discharged to the outside from a front panel 3 through a bell mouth 5 of a body frame 4, through an impeller 6 having blades 9, and a side plate 7 and a main plate 8 of which diameters get larger as they get closer to a motor 13 side, and through a flow passage enclosed by a motor frame opening 18 of a motor frame 10 and a motor 13 wind tunnel pipe 2.
