There are many fan blade design, the wind will become detailed, soft, and it is not like ordinary fans that will make people mood become irritable sound.
It uses a no-corner design, both tactile and visual, which makes people feel comfortable, and if you have a child at home, you no longer have to worry about him putting his hand in or those sharp corners hurting him.
The secret to its silence is the use of a good motor, high sealing and aviation lubricants. Another favorite feature is that it comes with a negative ion evolution function, which can reduce the dust floating in the air, so that people feel relaxed and feel the fresh air. At a time of year when haze is a regular feature, this isn't the best of both worlds.

About its charging problem, do not worry, to protect the environment is everyone's responsibility, so not with batteries is to use the wire. For such a good-looking and practical mute fan, like it.
3, bladeless fan
Bladeless fan is also called air doubler, because it does not have fan blades to facilitate cleaning and will not hurt the fingers of curious children. Its airflow is soft and natural wind is very similar to the traditional fan without the feeling of flapping. It is very suitable for the elderly, children and pregnant women.
How to buy a silent fan
1. Judge the quality of the plastic parts of the appearance of the color of the silent fan, it is best to choose the white color, it must be injection molded out of the white, not the white of the oil spraying, you can buy the product can be observed by the inside and outside of the product color is the same to judge. Because the white products must be raw materials to produce, and spray color products can be used second-hand material (scrap) to produce, and then sprayed with color to cover up the poor quality of plastic products. The market more than 100 silent fan is mostly sprayed color, this point you can go to test. This method can also be used to buy other pigmented products. Plastic material is about twice as expensive as used material.
2. Determine whether the brushless motor or brush motor to check the wind out of the gap edge whether there is black powder, pay attention to be sure to see whether it is black, if the edge of the black powder, indicating that the manufacturer used a carbon brush motor to produce silent fan, and carbon brush silent fan in the process of running the carbon brushes will continue to wear out the carbon brushes, and also have a black powder blowing out. This brush motor life is generally below 2000 hours, that is to say, if you use 10 hours a day, half a year or so the motor is scrapped. Truly silent fans should use brushless motors, which require a digital control chip to drive and have no life expectancy. If you can disassemble the machine to check, there is no drive board (not switch, adjust the wind speed, remote head and other functions of the control board) of the product must be the use of brush motor. A true silent fan has a larger driver board, a control board for switches and other functions. Brushless motors are about twice as expensive as brushed motors. And a sine wave driver board for a brushless motor costs about $50, which means that just the motor and driver board alone are about $70 more expensive for a brushless than a brushed one.
3. Check whether there is a flour flavor adjust the silent fan to the maximum wind speed, with the nose to smell the wind blowing out, whether there is a stench (toner flavor), if there is a smell must be brushed motor, we can not be fooled.
4. Check whether there is high-frequency noise adjusting the wind speed of the silent fan, will be close to the ears of the air inlet, listen carefully to the sound, if there is a clear motor sound (high-frequency sound), indicating that the fan using the driver board is not a sinusoidal wave, but a square wave of the quality of less than the standard, and the longer the use of the time, the louder the sound will be.
