1. If the air compressor is on for a long time in other positions in the factory, pneumatic control is selected, which has the advantages of high speed, high efficiency, convenient maintenance, low maintenance cost and simple and reliable structure, but the control accuracy is not very high.

2. There are many types of electric control, high precision and high maintenance cost. For example, there are electromagnetic control, motor and driver control, etc. , the control accuracy is extremely high. It is used in the case of very high accuracy of motion trajectory. The disadvantage is that the failure rate is slightly higher when used in harsh environment (serious oil pollution and excessive dust).

Therefore, it is suggested to use pneumatic control in places with low precision requirements and electronic control in places with high precision requirements.
