from the inlet guide vane the air reaches the high-speed rotating impeller which imparts kinetic energy by its centrifugal force the accelerated air is then changed into pressure by the diffuser and collected efficiently by the scroll [Music] the air which is heated to a high temperature at the time of compression is cooled by an intercooler and then goes through a second compression stage and intercooler [Music] followed by a third compression stage and an after cooler this method of increasing the pressure at several stages enables efficient compression and cooling action until the air is discharged from the compressor outlet [Music] you
