Citadel architectural solutions introduces a new concept of wind operated vergola turbo ventilators as a low cost alternative for the conventional electrically operated ventilators / exhaust fans. The vergola 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 convection current and in the process, they extract stale air together with air, which has become hot due to the building exposure. The product portfolio of citadel architectural includes openable roofs, polycarbonate roofing solutions, turbo ventilators, aluminium composite panel, pvc collapsible doors and frp sheets etc.
