What is the general pressure of compressed air

The pressure range of compressed air is quite wide, depending on the application scenario and equipment requirements. The following are some common compressed air pressure ranges:

low-pressure air: The pressure is usually between 0.1 and 1.0 MPa (megapascals). This pressure range of compressed air is mainly used for some relatively simple pneumatic equipment and tools, such as pneumatic grinding machine, pneumatic nail gun, etc. In addition, in automotive air conditioning systems, the low pressure is usually between 1.0 and 2.5 bar.

Medium pressure air: The pressure range is generally between 1.0 and 10 MPa. Medium pressure air is widely used in industrial production, such as pneumatic control system and pneumatic transmission system. In some specific applications, such as shoemaking, packaging, cleaning and transportation, the pressure range of the medium pressure air may be more specific, for example between 0.7 and 1.4 bar.

High-pressure air: Its pressure range is usually between 10 and 40 MPa. This high-pressure air is mainly used in special fields, such as high-pressure gas cylinder inflation, pneumatic equipment in the aerospace field, etc. In automotive air conditioning systems, the high pressure range is usually 15 to 18 bar.

Ultra-high-pressure air: Its pressure exceeds 40 MPa, usually used for special process requirements such as high-pressure water jet cleaning, high-pressure gas transmission, etc.

It should be noted that different countries and regions may have different standards for compressed air, and the pressure of compressed air in specific applications will be selected and adjusted according to local regulations and standards. In addition, when selecting the compressed air pressure, specific work requirements, equipment specifications and safety factors should be considered to ensure the efficiency and safety of the operation.

In general, the pressure range of compressed air is very wide, from low pressure to ultra-high pressure. The specific choice of pressure depends on the actual application scenario and equipment requirements.
