Centrifugal Air Compressors: Class 0 Oil-Free Air for High-Volume Plants
Big, steady base-load air with zero oil by design from Sullair Class 0 centrifugal systems, sized to plants that run continuously.
What a centrifugal compressor is and who needs one
A centrifugal air compressor uses high-speed impellers to turn air velocity into pressure, delivering large volumes of clean, oil-free air for plants with steady, high-capacity demand. It is the right fit for high-capacity centrifugal systems in pharmaceuticals, food and beverage, electronics, automotive, and utilities, where a big base load runs continuously. Brabazon supplies and services Sullair Class 0 oil-free centrifugal compressors, with the F Series reaching flow rates up to 118,000 CFM.

How to choose between centrifugal and rotary screw
Base the decision on volume and how steady it is. A centrifugal compressor is most efficient at full, sustained flow, so it pays back when a large base load runs nearly continuously. Rotary screw compressors modulate part-load demand more economically and fit plants whose air use rises and falls. Size the flow your plant actually needs with our CFM calculator, then compare designs on the rotary screw compressors page.
Where centrifugal compressors do the work
Sullair centrifugal compressors serve high-capacity plant air across pharmaceutical and medical, food and beverage, electronics, automotive, and power generation facilities.
Lower-flow plants are usually better served by oil free rotary screw or standard rotary screw compressors. Installation, service and repair, and compressed air audits are backed by 14 Midwest locations, including Milwaukee and Chicago.

Centrifugal compressor questions, answered first
What is a centrifugal air compressor?
A centrifugal air compressor uses high-speed impellers to accelerate air and convert that velocity into pressure, usually across multiple stages with intercooling. It is a dynamic, oil-free design built for large, steady air demand. Sullair centrifugal compressors deliver Class 0 oil-free air, with the F Series reaching flow rates up to 118,000 CFM.
When is a centrifugal compressor the right choice?
Centrifugal compressors win at sustained high volumes, where a large base load runs continuously and their efficiency at full flow pays back the higher cost. Sullair centrifugal machines suit high-capacity plant air in pharmaceuticals, food and beverage, electronics, automotive, and utilities. Below that sustained volume, a rotary screw compressor is the right choice because it modulates part-load demand more economically.
Are centrifugal compressors oil-free?
The Sullair F Series and T Series are Class 0 oil-free centrifugal compressors, which benefits applications where air purity is essential such as pharmaceuticals, food and beverages, electronics, automotive painting, and textiles. Oil lubricates the gears and bearings but never touches the air stream.
How does Brabazon support centrifugal compressors?
Brabazon is an authorized Sullair dealer, and factory-trained technicians size, install, and service centrifugal systems with 24/7 emergency response from 14 Midwest locations. Family owned since 1978, we help you decide between centrifugal and rotary screw before you commit.
