Turbine Ventilator for Roof Ventilation
The turbine fan utilize the natural wind speed of the natural world to push the turbine's turbine rotation, and uses the principle of indoor and outdoor air convection to accelerate and transform any parallel direction of air flow into a bottom-up vertical air flow to improve indoor ventilation. A device for gas effect. The fan does not need electricity, no noise, and can operate for a long time. According to the natural law of air and the principle of airflow, it is rationalized to be placed on the top of the roof, which can quickly discharge indoor hot air and dirty gas to improve the indoor environment.
