f-series Oil Free Centrifugal Air Compressors

EFFICIENT AERODYNAMICS. LOW MAINTENANCE.

f-series Oil Free Centrifugal Air Compressors

f-series centrifugal compressors are high performance, custom-designed compressors to meet your specific needs. The f-series takes flexibility, power, and pressure to a higher level. f-series compressors are available in both packaged and non-packaged options, with compression available from single stage up to four stages.

All Sullair Centrifugal compressors rely on a simple design — which not only reduces the potential for mechanical loss but also simplifies maintenance and operation.

  • Energy Efficiency – The optimal combination of components — from specially designed titanium impellers to tilting pad journal bearings – help Sullair centrifugal compressors operate with high efficiency which results in lower power consumption.
  • Low Maintenance – The simple design means fewer moving parts. Because many of the components have a very low potential for wear, ongoing maintenance is significantly reduced. The horizontally split gearbox bearing, along with a split bearing and seal design, offers easy and convenient access to maintenance items: all moving parts can be checked by simply removing the gear box cover.
  • Ease of Operation – Sullair Centrifugal Compressors are designed to be installed — and run. The compressor is equipped with many features that are packaged as standard — minimizing installation time.
