Natural Ventilation Fans
 
Natural Economical ventilation all year round without power or operation costs.An energy saver for the better tomorrow.
 
Working
The ventilator operates by utilizing the velocity energy of the wind to induce airflow by centrifugal action.The centrifugal force caused by the spinning vanes crates a region of low pressure area, which draws air out through the ventilator.Air drawn out by the ventilator is continuously replaces by fresh air from the outside.

The slighest breeze will cause the ventilator to spin and even after the breeze has stopped,the flywheel effect of the rotor cage will use its stored energy to continuosly to remove air giving rise to ventilation.Suction is maintained even at low wind velocities.
