The overload protective device in controller box can automatically disconnect the power supply once accident occurs. So safety is assured. You can regulate the wind speed at will by rotary switch. What's more, the inverter can control the fan to rotate in forward and reversing direction.

Our fans have TEN PCS of blades and winglets to ensure maximum airflow and efficiency. Unique designed winglets at the airfoil tips greatly eliminate wind noise. The blades is made of aluminum alloy with plastic spraying finish, so it can resist corrosion and dust very well.
