The Turbo Ventilator operates by harnessing the full velocity energy of the wind to induce airflow by centrifugal force. During rotation the centrifugal force created draws the air in the turbines towards the spinning vanes and out of the turbine. The airfoil vanes act as cups, catching the wind at the windward side of the turbine. Simultaneously air is forced out at the leeward side creating continuous airflow; giving rise to ventilation. These wind driven ventilators, unlike doors and windows, draw air upwards, creating convention current and in the process, they extract stale air together with air, which has become hot due to the building exposure.
