The amount of pressure on an air compressor usually depends on its design and application needs. Generally speaking, the pressure range of industrial air compressors is between 0.7~1.2 megapascals (MPa), which is equivalent to 7~12 bar (bar). This pressure range is usually sufficient for most industrial processes.
However, there are also some special-purpose compressors that can provide higher pressures. For example, high-pressure air compressors can be used in applications that require higher pressures, such as certain special processes or high-pressure gas storage. The pressure range of these high-pressure compressors may exceed the conventional range described above.
In addition, home compressors are often used for lighter tasks such as inflating balls, tires, or performing simple purging jobs, so their pressure requirements are relatively low. The output pressure of a household air compressor is generally between 80~120 pound-force per square inch (psi), which is about 0.4~0.8 MPa or 5~10 bar when converted to other units.
When selecting an air compressor, it is important to determine the required pressure range based on the specific application needs and operating environment, and to ensure that the compressor selected can meet those needs. At the same time, the relevant safety guidelines should always be followed when operating the air compressor to ensure the safe operation of the equipment.
