<p>The axial flow fan stator consists of a series of radial arms extending from the outer wall of the fan to a central support for its motor. Each of the arms is in at least two parts (10, 11) lying in line with the air flow through the fan, with gaps (12) between. Each of the arm parts has a curved cross-section and is thicker at its leading edge than its trailing edge.</p> |
