1. More energy-efficient: With the same air volume, the power consumption is much lower than that of traditional AC fans, and some models can save more than 50% energy.

 2. Quieter: Due to the absence of brush friction and automatic speed control, the noise level is significantly reduced, making it suitable for places where sound sensitivity is an issue.

 3. Smarter: It allows for stepless speed adjustment, such as automatically speeding up when the temperature rises and slowing down when it drops, without the need for manual adjustment.

 4. The price is slightly higher: because it includes additional control circuits and permanent magnet materials, it is more expensive than ordinary fans when purchased. ‌‌‌

Where is it generally used:

 1. Household appliances: commonly used in refrigerators, air conditioners, and air purifiers, for energy saving and noise reduction.

 2. Ventilation equipment: The building's fresh air system and exhaust fans, which require long-term operation and energy conservation.

 3. Electronic equipment: cooling fans for computer servers and industrial control cabinets, requiring stability and low noise.
