AXIAL FLOW BLOWER

摘要

Provided is an axial flow blower wherein noise is reduced by ensuring the effective work of blades and suppressing the blade tip vortex. The axial flow blower is formed so that a chord center line (37) extending so as to connect chord center points (34) from the inner peripheral end to the outer peripheral end of a blade (3), is curved and projected toward the downstream side in the entire region.
