Industrial AC fans and commonly used household AC fans in the following aspects there are significant differences:

1. Use and use of the environment: industrial AC fans are mainly used for ventilation in factories, warehouses and other environments to improve air circulation and work efficiency, while household AC fans are mainly used in homes, offices and other occasions for cooling, dust and other needs, the use of the scene is more flexible and family-oriented.

2. Power and air volume: industrial AC fans have high power, fast rotation speed and high air volume, which can transport a large amount of air from one place to another in a shorter time to meet the needs of industrial production. The household AC fan power is relatively small, slow speed, moderate air volume, to meet the family's daily ventilation and cooling needs.

3. Structure and materials: The structure and materials of industrial AC fans are usually stronger and more durable, able to withstand higher operating temperatures and harsher working environments. For example, the motor, outer frame, bearings, grommets, springs, silicon steel sheets and other components of industrial AC fans are usually made of higher quality materials to ensure their long-term stable performance.

4. Control: industrial AC fans usually use frequency control, remote control and other methods to achieve more accurate and flexible air volume adjustment and control. Household AC fans are usually controlled manually or by a simple remote control, the control mode is relatively simple.

5. Safety performance: industrial AC fan safety performance requirements are higher, need to have overload protection, leakage protection, explosion-proof and other functions to ensure safety in the industrial production process. Household AC fan safety performance requirements are relatively low, usually only need to have a basic overload protection and leakage protection.

To summarize, there are significant differences between industrial AC fans and commonly used household AC fans in terms of use, power, air volume, structure and materials, control methods and safety performance. When choosing and using AC fans, they should be selected and used according to the actual needs and use of the environment to ensure that they can meet the needs of production and life.
