Abstract

PURPOSE: To provide a multivane fan wherein airflow above a conventional one is obtained at a similar number of rotations by planting vanes at both sides of a vane- supporting body, and alternately arranging the roots of the vanes at both sides in a zigzag form.
CONSTITUTION: A plurality of vanes 2 which extend in an axial direction at one side of a vane-supporting body 1 are planted along the periphery of the vane-supporting body 1 at fixed intervals. Also, a plurality of vanes 21 which extend in an axial direction at the opposite side of the vane-supporting body 1 are planted along the periphery of the vane-supporting body 1 at fixed intervals. The roots of the vanes 2 and the roots of the vanes 21 are alternately arranged in a zigzag form.
