The expansion of the application of pneumatic technology is the symbol of the development of the pneumatic industry. The application of pneumatic components is mainly two aspects: maintenance and matching. In the past, the sales of domestic Pneumatic Actuator Elements should be used for maintenance. In recent years, the sales share of the main components has increased year by year. The application of domestic Compact Pneumatic Cylinder from metallurgical equipment with a value of thousands of yuan to a chair with only 1~2 hundred yuan. Railway wrenching, locomotive wheel rail lubrication, train brake, street cleaning, lifting equipment in special workshop, military command vehicle and so on are all used specially developed domestic pneumatic components. This shows that the pneumatic technology has been "penetrated" to all walks of life, and is expanding.

Although China's pneumatic industry has reached a certain scale and technical level, but compared with the international advanced level, the gap is very large. The output value of China's pneumatic products is only 1.3% of the world's total output value, only the 1/21 of the United States, the 1/15 of Japan, and the 1/8 of Germany. This is very disproportionate to the great power of the about 1000000000 population. In terms of varieties, a Japanese company has 6500 varieties, our country only has its 1/5. The gap between the product performance and the quality level is also great.
