Gas compression can be divided into volumetric and speed type according to the principle, piston air compressors are commonly used volumetric compressors, while centrifugal compressors are speed type compressors. The advantages of centrifugal compressors compared to piston compressors are obvious: compact structure, small size, large displacement, small consumption of raw materials; less wearing parts than piston compressors, long continuous operation cycle; no friction in the cylinder, no lubrication; continuous and stable air supply.
