Due to the strong axial and radial load to the bearing of electromotor in counter-rotating axial fan, it is always occurred that the bearing was damaged in use.
Using the streamline curvature method and the full radial equilibrium equations, the duct flow calculations of an axial_flow fan are presented in this paper.

The tube silencers 23 have open end portions arranged to face the fan and the silencers of the first set 18 are spaced from the silencers of the second set 24 in both axial and radial directions.
