Ventum wind driven turbine ventilator is driven by natural horizontal wind and vertical airflow caused by temperature difference between indoor and outdoor. Due to the scientific design of vanes, turbine ventilator can even be driven under breeze. The rotating turbine head will produce centrifugal force, which exhaust the hot air, fume, humidity. As air exhausts, negative pressure zone will be formed under the turbinehead where fresh air could get into constantly. The turbine head keeps on rotating which achieves the purpose of venting and exhausting.
