The pressure of an air compressor is usually determined based on the specific application needs and will be affected by the environment in which it will be used and the specifications of the equipment. Generally speaking, the pressure of the air compressor can be divided into the following ranges:
Low-pressure air compressors: The working pressure is usually between 0.7 and 1.2 MPa (megapascals), which is equivalent to 7 to 12 bar. The air compressor in this pressure range is suitable for some occasions where the air pressure requirements are not too high.
Medium pressure compressors: The working pressure is usually between 1.2 and 3 MPa (megapascals), i.e. 12 to 30 bar. This is the most common pressure range in industrial applications and can meet the needs of most pneumatic tools and equipment.
High-pressure air compressors: The working pressure is usually more than 3 MPa (megapascals), which is more than 30 bar. This type of high-pressure compressor is often used for specific industrial applications that require extremely high pressures, such as some special processing processes or experiments.
In addition, there are some specific areas that have specific requirements for the pressure of air compressors, such as:
In the aerospace sector, due to the very high requirements for components, higher air pressures may be required, and the pressure of air compressors may exceed the range of general industrial applications.
In the field of medical and health care, air compressors are mainly used for oxygen inhalation in wards, dental equipment, operating tables and other equipment, and the output air pressure range is relatively low, usually between 0.7 and 0.8 MPa (7 to 8 bar), in order to ensure the flow and purity requirements of medical gases.
In general, the pressure range of air compressors is wide, and the appropriate pressure level should be selected according to the specific application scenario and needs. When choosing an air compressor, in addition to the pressure demand, you also need to consider factors such as equipment type, specifications, process requirements, and energy efficiency.
