ABSTRACT:
The present invention provides an axial flow fan capable of increasing an air volume and static pressure more than conventional axial flow fans. A plurality of rotary blades5are disposed in a circumferential direction of a rotary shaft8at equidistant intervals. A plurality of stationary blades11are disposed in the vicinity of a discharge opening16of an air channel portion19of a housing3. The stationary blades are disposed in the circumferential direction of the rotary shaft8at equidistant intervals. The number of the rotary blades is seven (7) and the number of the stationary blades11is eight (8).
