How to buy an electric fan The method of buying an electric fan

1, look at the fan blade: the more fan blades, the more dense the wind cut, the wind effect is softer, the wind is more stable. Generally five air blades of the inner diameter of the air blades than three air blades, and three air blades of the twist angle than five air blades, so five air blades of the wind volume, wind effect is soft, three air blades of the wind speed, wind effect is hard.

2, look at the motor material: the core component of the motor is the movement, the movement material has a variety of materials, and the most used materials on the market are: pure copper movement, copper-clad aluminum movement and aluminum wire movement. Pure copper movement conductivity, and attenuation coefficient is small, the longest life, the most expensive; followed by copper-clad aluminum, followed by aluminum wire motor.

3, look at the capacitor configuration: capacitor as an important part of the fan, can be reflected from the side of the motor's strengths and weaknesses. In general, the smaller the value of the capacitance of the household electric fan, the smaller the motor starting current, the more energy efficient, the performance of the motor is relatively more stable. In addition, the larger the rated voltage value, the capacitor's ability to withstand voltage shocks, the motor performance will be relatively more stable.

4, look at the gear settings and maneuverability: in the purchase, the user also needs to pay attention to the gear settings of the fan, multiple gears can provide a variety of air volume and a variety of modes to choose from. In terms of maneuverability, many machines with remote control or can be connected to a cell phone for control, lying in bed can be controlled, relatively speaking, much more convenient.

5, look at the fan shaking head way: the fan shaking head determines the scope of its air supply, general fan shaking head is divided into up and down, manual, tilt, left and right shaking head, 360 degrees shaking head, O shaking head and eight shaking head. Oscillating head can be selected according to demand, if the use of a wide range of people should be prioritized to choose the left and right oscillating head function, if you need to adjust the air conditioning temperature, to promote air circulation should be selected 360 degrees or O oscillating head.
