1. Compressed gas is used as a power source. After compression, air can be used for power, mechanical and pneumatic tools, as well as control instruments and automation devices.

2. Compressed gas is used for refrigeration and gas separation. Gas liquefies through compression, cooling, and expansion, and is used for artificial refrigeration, commonly referred to as an ice maker or freezer. If the liquefied gas is a mixture, each component can be separated separately in the separation device to obtain various gases with qualified purity. The separation of petroleum cracking gas involves first compressing and separating each component separately at different temperatures.

3. Compressed gas is used for synthesis and polymerization in the chemical industry. Some gases are advantageous for synthesis and polymerization after being pressurized by a compressor. For example, helium is synthesized from atmosphere and hydrogen, methanol is synthesized from hydrogen and carbon dioxide, and urea is synthesized from carbon dioxide and ammonia. Production of polyethylene under high pressure.

4. Gas transport compressors are also used for pipeline transportation and bottling of gases. Such as remote transportation of gas and natural gas, bottling of chlorine and carbon dioxide, etc.
