(b) Double suction impellers: It takes the gas in axial … Speed range - They are efficient over a wider range of rotational speeds than axial compressors. The axial compressor's capital cost is higher than that of a centrifugal but may well be justified by energy cost savings in an overall evaluation. As the compressor sucks the air axially and increases  its energy level by flowing air through the rotor blades that rotates and exert a torque on the air.Now the stationary blades slow down the speed of the fluid and converts the circumferential component of air into the pressure.So the air get compressed in this way. One of the interesting characteristics of the centrifugal compressor is that as the speed of the impeller reduces the capacity of the compressor increases.The air is sucked axially by the impeller and the blades impart the additional energy which is converted into pressure energy by the diffuser and then easily delivered from the collector casing. Centrifugal compressor parts and its function Single stage and Multi stage compressor - Advantages and Limitation Axial compressor: It … Axial compressors are probably the rarest type of compressor as they are so powerful that they are reserved for use in things like engines and power generators.
