Industrial Purpose Roof Ventilator is attached with a turbine, which helps these to use wind energy for starting the air flow. The Roof Ventilator uses centrifugal action for creating a low pressure area by the winds, which is mainly the cause of the spinning action. The Roof Ventilator ensures that at the slightest breeze, this turbine can rotate removing the air with the help of fly wheel effect of the rotor cage. Industrial Purpose Roof Ventilator is highly energy efficient and delivers hassle free performance.
