Cyclone Ventilator-Roof Fan-600mm Diameter

The roof fan is a device that uses the natural wind speed of nature to promote the turbine rotation of the fan, and uses the principle of indoor and outdoor air convection to accelerate and transform any parallel air flow into a vertical air flow from the bottom up to improve the indoor ventilation effect. The fan has no electricity, no noise and can run for a long time. According to the natural law of air and the principle of air flow, it is rationally set on the top of the roof, which can quickly discharge the hot air and dirty gas in the room and improve the indoor environment.
