What is the general pressure of compressed air

The pressure range of compressed air varies according to application requirements and depends on the type of compressor, design specifications, working conditions and specific application scenarios. Generally speaking, in conventional applications, the pressure of compressed air is usually between 0.4 MPa and 1.0 MPa, which is equivalent to a pressure of about 4 kg to 10 kg. The pressures within this range can meet the needs of most industrial and commercial applications.

In the industrial field, the pressure range of compressed air may be more specific. For example, the compressed air pressure commonly used in some factories is from 0.6MPa to 0.8MPa, a range suitable for pneumatic tools, automation equipment and other industrial applications. Convert to other units, this pressure range is about 6 to 8 kg, or 6 to 8 bar.

However, in some special high pressure applications, the pressure of compressed air may exceed 1.0MPa. For example, deep-sea diving requires higher pressure to support divers’ activities underwater, high-pressure cleaning requires high-pressure airflow to remove stubborn stains, and high-pressure spraying can improve coating efficiency and coating quality.

In addition, from the perspective of compressors, different types of compressors will also generate different ranges of pressure. For example, compressors with lower power usually have a working pressure of 6-8 bar, which is suitable for low-pressure application scenarios such as painting and spraying; while compressors with higher power may have a working pressure of between 8-14 bar, which is often used in scenarios such as pneumatic transmission and drilling, where high-pressure air is required.

In general, the pressure of compressed air is a parameter that depends on the specific needs and application scenarios. In practical applications, it is necessary to consider a variety of factors to select the appropriate air compressor and its pressure value to ensure the normal operation of the compressor and meet the process requirements.
