Centrifugal compressors have following advantages :

• short length due to high pressure ratio obtained in a single stage.
• simple in design, easy to manufacture, rugged in construction, less costly.
• more reliable in operation under all operating condition.
• less susceptible to the effects of DEPOSITS LEFT on flow path.
• less sensitive to the FOULING of the flow path.
• Good efficiency over a wide range of operation.

Drawback is larger cross-section area for same capacity and its unsuitability for high pressure RATIOS. Axial flow compressor is more popular due to high delivery capacity, high compression ratio due to many stages, high efficiency (85-90%), low cross sectional area. Its drawback is sophisticated design and APPRECIABLE length due to large number of stages, narrow operating range for good efficiency, higher weight and cost, high starting power.
