1. Compressor can provide high pressure gas to meet the needs of many industrial manufacturing processes that need high pressure gas, such as spraying, die-casting, melting, etc.
2. Compressors compress gas into smaller volumes, reducing the cost of storing, transporting and handling it.
3. Compressors can be used to make gas mixtures, such as air and gas mixtures, to meet the needs of different industrial processes.
4. Compressors can also be used to provide aerodynamic equipment, such as wind turbines and pneumatic tools.
5. Compressors can also be used to produce gas fillers, such as foam plastics and air cushions.
6. In refrigeration and air conditioning systems, compressors provide coolant and circulate coolant through the system to provide refrigeration and air conditioning.

In short, compressors are widely used in industrial manufacturing, and can provide a variety of gases to meet the different needs of industrial production processes, so as to improve work efficiency and reduce costs.
