Dax engineering & marketing services manufactures low cost wind driven turbo ventilator with technical special features of adaptability, high capacity per vent and reliability. The concept of these wind ventilator is a virile ventilator operates by harnessing the wind velocity to induce airflow by centifugal force. As the vent hood is rotated by the wind, the stale air inside is exhausted through the wanes and a natural inward flow of fresh air is boosted. These wind ventilators are strong proof, maintenance free with no operating cost since it runs on wind power. The ventilator can operate even at just 3 kms per hour speed of the wind. The centrifugal force created draws the air in the turbines towards the spinning wanes and out of the turbine.
