PURPOSE: A compressed gas purifying system using a centrifugal impeller is provided to separate foreign matters such as water and oil from air centrifugally by difference of specific gravity between pollutants and gas, to improve dehumidifying efficiency by rotating a centrifugal impeller at high speed, and to reduce cost by injecting compressed air. CONSTITUTION: A centrifugal air purifying system(307) comprises a turbine(333) installed in the lower part of the centrifugal air purifying system to rotate at high speed by injection of compressed air; a centrifugal impeller(308) rotated and fixed to a rotating shaft(335) of the turbine; a bearing(334) supporting the rotating shaft connecting and fixing the turbine to the centrifugal impeller; and a centrifugal air flow guide installed in an air pipe to rotate the turbine at high speed. The life span of the equipment is extended, and maintenance cost is reduced by separating pollutants including water and oil from air efficiently.
