Centrifugal compressors are divided into single-stage and two-stage or multi-stage types based on the mode. Single stage compressor

In this compressor, only one propeller is used to compress the air and they are used at low pressures. In single-stage compressors, the impeller is located at the top of the rotor. The features of this compressor include simple design and easy operation.

Two-stage or multi-stage compressor

In this type of compressor, according to the working stages, the cylinder is located with different drops and between each compression stage, an intercooler or cooling It is located to reduce the temperature. Among the advantages of this type of compressor compared to single-stage compressors, we can point out humidity reduction, greater efficiency and reliability. Centrifugal compressors are also divided into two types of oil and oil-free centrifuges based on the lubrication method.
