1. An efficient axial fan with multiple profiles and a beam placed on a hub, comprising:
an upper camber, a mean camber, and a lower camber with a positive torsional angle of 15° counterclockwise at a rate of an increase in a linear velocity from a first bottom to a first tip,
a tip end connecting ends of wings to prevent eddies to form at the ends,
a roof end connecting a bottom of the wings, and
at least one middle beam positioned between the lower camber and the upper camber associated with the tip end and the roof end,
wherein, the mean camber fixed on the at least one middle beam located 90 degrees perpendicularly between the lower camber and the upper camber.
