For more than 50 years, FS-Elliott has been a supplier of centrifugal air compressors for industrial and engineering use. The FS-Elliott compressor series consists of a complete range of models, built-in with sophisticated tilted impellers made of 17-4PH stainless steel. These compressors are reliable, using high-tech coaxial rotary gears, one-piece high-rigidity casings, bundle coolers in water piping, horizontally split seals, self-correcting high-load capacity bearings, low-friction tilting pad bearings, and 4-in-1 modular advanced controllers.
The Polaris+ centrifugal compressors feature a simple and effective design that outperforms other compressors in delivering trouble-free operation and the lowest cost of ownership. Not only does it use certified ISO 8573-1 Class 0 oil-free air for purity that meets exacting standards, but it has also eliminated the need for periodic and expensive wearing parts replacements while still performing with excellent reliability over extended periods. Low-to-no vibration is achieved, even without any special foundations. In addition, Polaris+ compressors are provided with a variety of Regulus® controller system options for superior control.
The compressors are designed with 2-stage and 3-stage operating pressures, ranging from 3 to 10.5 kg/cm2 (40 to 150 psig). They run between 185kW and 2240kW (250HP~3000HP), and yield discharge volumes from 900 to 11500 CFM (25~330 m3/min).
