The Centrifugal Air Compressor is a dynamic compressor which depends on transfer of energy from a rotating impeller to the air. This compressor consist of two types: Lubricated and Axial (Oil Free).
The centrifugal-type is the most common and is widely used for industrial compressed air. Each impeller, rotating at high speed, imparts primarily radial flow to the air or gas which then passes through a volute or diffuser to convert the residual velocity energy to pressure energy. Some large manufacturing plants use centrifugal compressors for general plant air, and in some cases, plants use other compressor types to accommodate demand load swings while the centrifugal compressors handle the base load.
Axial compressors consist of a rotor with multiple rows of blades and a matching stator with rows of stationary vanes. The rotating blades impart velocity energy, primarily in an axial plane. The stationary vanes then act as a diffuser to convert the residual velocity energy into pressure energy. This type of compressor is restricted to very high flow capacities and generally has a relatively high compression efficiency. Mixed flow compressors have impellers and rotors which combine the characteristics of both axial and centrifugal compressors.
