Abstract

The present invention describes an axial flow fan blade that presents innovation on its shape that results in a lower noise emission and in a higher efficiency. The axial flow fan blade, object of the present patent, has a lower vortex emission than the blades available on the previous art. This lower vortex emission is responsible for a lower level of pressure fluctuations, which results in a lower noise emission, and is also responsible for a lower energy expense on the vortex formation, which results in an efficiency increase. The present axial flow fan blade can be employed in various applications where it is necessary to move any gas.
