1. The air source processor has the advantages of simple structure, light weight and simple installation and maintenance. The medium is air, which is not easy to burn compared with hydraulic medium, so it is safe to use.

2. The working medium is inexhaustible air, and the air itself costs no money. The exhaust treatment is simple, does not pollute the environment and has low cost.

3. The adjustment of output force and working speed is very easy. The action speed of the cylinder is generally less than 1m / s, which is faster than that of the hydraulic and electrical modes.

4. High reliability and long service life. The effective action times of electrical components are about one million times, while the service life of general solenoid valves is more than 30 million times, and some valves with good quality are more than 200 million times.

5. Using the compressibility of air, energy can be stored to realize centralized gas supply. Energy can be released in a short time to obtain high-speed response in intermittent motion. Buffering can be realized. Strong adaptability to impact load and overload. Under certain conditions, the pneumatic device can have self holding capacity.
