If you’re thinking of purchasing a centrifugal air compressor, what are some of its benefits? Well, a centrifugal air compressor is a dynamic machine that has numerous advantages over conventional rotary screw compressors. They are oil-free, meaning cleaning air and reduced maintenance costs. They operate by creating air pressure through rotating disks (impellers) and a diffuser plate that has the ability to convert velocity energy to pressure energy. This system compresses air in multiple stages. Multiple stages increase the efficiency of the compression process, allows for better heat transfer to cool the air, and helps the compressor perform at differing part loads while maintaining its performance benchmark.


Centrifugal air compressors can run continuously for long periods of time, and that’s one of their main strengths. It’s no wonder they’re commonly found in large manufacturing plants. Able to handle large flow rates at varying pressures, they’re consistent, reliable, and efficient machines that don’t sacrifice efficiency at part loads. If controlled correctly they are the best choice of compressor pound for pound. They’re compact, too, so they don’t take up as much floor space as multiple screw compressors to make up the difference.

Low Maintenance

Do you need equipment that produces a constant flow of high-pressured air that’ll meet high demands? Then the centrifugal air compressor is a good choice. Utilizing oil-free compressed air, this type of compressor has a limited few wearing parts so there’s not a lot of need for maintenance. Centrifugal compressors require less maintenance intervals. There’s no cost for an oil change because they are oil free and overall, less consumables compared to their counterparts. These compressors tend last a very long time, we still encounter compressors built in the early 1980’s still running today.
