Centrifugal Air Compressors
The centrifugal air compressor is a dynamic compressor, which depends on transfer of energy from a rotating impeller to the air. The rotor accomplishes this by changing the momentum and pressure of the air. This momentum is converted to useful pressure by slowing the air down in a stationary diffuser.
The centrifugal air compressor is oil-free by design.
The oil-lubricated running gear is separated from the air by shaft seals and atmospheric vents.
It is also a continuous duty compressor, with few moving parts, that is particularly suited for high volume applications.
