Polaris+ Centrifugal Compressors

Polaris+ centrifugal air and gas compressors suit a broad range of applications with models ranging from 250 hp to 2,600 hp in two and three-stage configurations that deliver up to 207 psig (14.3 psig) discharge pressure.

Centrifugal air compressors also referred to as dynamic compressors, are designed to produce large volumes of compressed air in an extremely energy efficient process. Although manufacturers that require over 200 to 250 total horsepower tend to realize the greatest savings, all industrial manufacturers should consider the advantages of centrifugal technology.

Oil-Free Compressed Air Stream

The risk of trace oil reaching the finished product or oil contamination in equipment lines leading to higher maintenance and downtime is avoided with a centrifugal compressor. Condensate generated from a centrifugal compressor is not subject to the same local regulations as oil-contaminated condensate, allowing for easy and low-cost disposal.

Fewer Maintenance Requirements

Centrifugal compressors do not rely on wearing surfaces to create compression, leading to longer-lasting bearings and other rotating components. The number of extra components such as oil and filters are drastically reduced saving material and labor costs. Polaris+ air compressors take maintenance-friendly operation a step further by offering a horizontally split gear case, allowing full access to the gearbox in the field and avoiding costly downtime.

Increased Energy Efficiency

Available in up to three stages, Polaris+ centrifugal air compressors are on average 5% more efficient than other technologies. As the number of stages increases, the compression ratio is lower, meaning higher efficiency.

How Does a Centrifugal Compressor Work?

Watch a Polaris+ air compressor in action as the air travels through each stage of the compression process, resulting in a reliable, ISO 8573-1 oil-free stream to power a variety of industrial applications.
