Delivering What Matters Most

The question isn’t “Which compressor can do the job?” Many can perform that basic function. More important is knowing which compressor works reliably longer, even in the most demanding environments. Which saves money by using energy more efficiently. Which is easy to install and use. Which minimizes downtime and the hassle of emergency repairs and ongoing maintenance.

The question is “Which compressor delivers what matters most?”

When you ask the right question, the answer is clear: FS-Elliott’s Polaris+ compressors not only “do the job,” they deliver the high quality, efficiency, and ease of operation that make any job more successful.
 

Why Centrifugal?

Efficient aerodynamics make centrifugal compressors ideal for a variety of industrial applications. Centrifugal compressors produce pressure by transferring energy from a rotating impeller to the air. Capacity can be controlled by adjusting the inlet guide vanes—closed to reduce and open to increase flow.

Polaris+ centrifugal compressors feature a simple, effective design that outperforms other compressors in delivering trouble-free operation and the lowest cost of ownership. Polaris+ owners enjoy:

• Certified ISO 8573-1 Class 0 Oil-free air for purity that meets exacting standards.
• Low maintenance with no wearing parts that require regular change-out. Eliminates the need for periodic and expensive air end replacement.
• Low-to-no vibration without any special foundation required.
• Superior control through a variety of Regulus® controller system options.
• Excellent reliability over extended periods with minimal maintenance.

 

Compression Flow Process

1. Ambient air enters the first stage through the inlet control device.
2. The first-stage impeller accelerates the air. A radial diffuser converts the air’s velocity into pressure before the air enters the scroll casing.
3. The air is conducted through interstage piping into the first intercooler.
4. The cooled air then flows into the second-stage inlet piping.
5. The compression process is repeated as the air passes through the second stage impeller, diffuser, and scroll casing, and then into the second intercooler.
6. Air from the second intercooler moves through a third impeller, diffuser, and scroll casing.
7. Air is discharged into the aftercooler and air system.
