High -rental electric adjustment function

The wind speed of the electric fan can be controlled by adjusting the engine power supply . the higher the voltage, the faster the fan blades rotate and, conversely, the decrease in the voltage will force the fan blades to rotate slowly and blow a light veterus .}}}}

The effect of the electric fan on the temperature in the room
Although the electric fan itself generates heat by converting electrical energy into heat, its main function is to promote heat scattering by ensuring air flow . The electric fan cannot reduce the actual temperature in the room, but it can accelerate the mixing in the room and help hot air, thereby creating convection on the surface the evaporation of sweat and reaching the cooling effect‌
