f-series Oil Free Centrifugal Air Compressors
EFFICIENT AERODYNAMICS. LOW MAINTENANCE.
![PIC_f-series-centrifugal-2_featured_0 f-series Oil Free Centrifugal Air Compressors](https://holtindustrialsystems.com/wp-content/uploads/2020/12/PIC_f-series-centrifugal-2_featured_0.png)
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.
