Principle | ||
Utilise wind energy to induce air flow by centrifugal action. Centrifugal force created by rotating vanes in turn creates low pressure zone which draws fresh air from outside. Thus replasing polluted air/hot air continuosly. Minimum wind pressure will spin ventilator and even after wind has stopped, the fly wheel effect of ventilator will use its stored energy to rotate and to maintain fresh air flow. |
