1. Compared with other devices, the volume of electric actuator is smaller, because the structure of electric actuator is simple, the components are simple, and the structure is very compact, so the volume is small and easy to assemble.

2. In the requirement of driving source, the advantage of electric actuator is more obvious than that of pneumatic device. Because of the simple requirements of the electric actuator for the driving source, generally the power supply of our vehicle can be used as the driving source of the electric actuator, but the pneumatic device needs the air source and the compression driving device to provide the driving source, which is obviously inconvenient.

3. The electric actuator does not need external power to maintain the load, while the pneumatic device needs continuous pressure supply to maintain the load. It is precisely because of this that the electric actuator is quiet when it works because there is no additional pressure device, but the pneumatic device needs external pressure supply, so there will be a more obvious sound during the execution In the case of load, we need to add an additional muffler to eliminate noise.
