General air compressor how many MPa

The normal supply pressure of the air compressor varies depending on its type and specification. Generally speaking, the pressure range of air compressor can be roughly divided into the following categories:

1. low pressure air compressor: The pressure range is usually between 0.4 and 1.2 MPa (MPa). It is also said that the exhaust pressure of the low-pressure air compressor is lower than 0.5 MPa. This type of air compressor is mainly used in light applications, such as inflatable toys, pump and other small equipment.
2. Medium pressure air compressor: The pressure range is usually between 1.2 and 3 MPa. It is also said that the exhaust pressure of the medium pressure air compressor is between 1.6 MPa and 4.0 MPa, or between 1.4 MPa and 10 MPa. Medium pressure air compressors are commonly used in printing and packaging equipment, pharmaceutical and food industries, automotive maintenance and painting.
3. High pressure air compressor: The pressure usually exceeds 3 MPa and can even reach higher levels, such as 40 MPa. High-pressure air compressors are often used in areas where high pressure is required, such as the oil and gas industry, chemicals and aerospace.

In addition, according to the displacement of the air compressor, it can also be divided into different types such as micro, light, medium and heavy, and their pressure ranges are also different:

• micro air compressor: The pressure is usually between 1 and 5 bar.
• Light air compressor: The pressure is usually between 5 and 10 bar.
• Medium-sized air compressor: The pressure is usually between 10 and 20 bar.
• Heavy-duty air compressors: pressures up to 25 to 30 bar.

It should be noted that the above pressure range is for reference only, and the pressure setting of the air compressor in actual use should be determined according to the specific application scenario and requirements. At the same time, during the operation, you should always pay attention to the pointer on the pressure gauge to ensure that the pressure reaches the standard and avoid excessive pressure to ensure the stable operation and safe use of the equipment.

In addition, for air compressors for general industrial purposes, the working pressure range is usually between 0.7 MPa and 0.8 MPa, which is also a common set pressure range for many air compressors. However, the specific pressure needs to be adjusted according to the model, specifications and actual conditions of use of the air compressor.
