The Advantages of Centrifugal
Compressor Technology
Integrally geared centrifugal compressors represent the latest
technology, offering significant advantages over outdated,
less-efficient and more costly compressor designs. These
advantages are inherent in the centrifugal design and
are further enhanced by Ingersoll Rand’s more than
60 years of centrifugal expertise.

2 centrifugal.ingersollrand.com
Compare the innovative technology of MSG and TURBO-AIR centrifugal compressors with other
machines, such as positive displacement compressors, and the advantages are clear.
