industrial centrifugal air compressors
ポラリス® P750
The Polaris P750 centrifugal compressor delivers reliable, energy-efficient, oil-free compressed air for large-scale industrial applications requiring high airflow capacity.
As the largest model in FS-Elliott’s Polaris series, the P750 provides airflow capacities up to 22,100 CFM (625 m³/min). Its advanced aerodynamic design helps optimize energy efficiency, while its compact footprint and maintenance-friendly construction simplify installation, servicing, and long-term operation.
Bridging the gap between industrial and custom-engineered centrifugal compressors, the P750 offers manufacturers a high-capacity compressed air solution with heat-of-compression (HOC) drying capabilities, designed to reduce operating costs, accommodate demanding application requirements, and support dependable performance throughout the compressor’s lifecycle.

Features & Benefits
The Polaris P750 is engineered to deliver ISO 8573-1 Class 0 oil-free air with the efficiency and reliability required for demanding, high-flow industrial applications. Its oil-free design helps protect critical processes from compressor oil contamination, while the Regulus control system and available monitoring capabilities provide greater visibility into compressor performance and support reliable long-term operation.
Confidence for Critical Air Demands
The Polaris P750 is engineered to deliver ISO 8573-1 Class 0 oil-free air with the reliability and efficiency required for demanding, high-flow industrial applications.
Its oil-free air path helps protect processes from compressor oil contamination, while Regulus controls and available monitoring capabilities help operators maintain visibility into compressor performance and condition.
Optimized Design, Efficient Operation
Polaris compressors combine optimized aerodynamics, efficient intercooling, and custom-designed impellers to reduce power requirements and optimize airflow.
Mechanically superior bearings and adjustable inlet guide vanes further support efficient operation by reducing power consumption and responding to changing plant conditions and air demand.
Designed with Service Access in Mind
The horizontally split gear case provides technicians with convenient access to internal components for inspection and service, while the removable airend simplifies maintenance and replacement to help minimize downtime. Straight-through intercooler tubes allow for easier periodic cleaning, and the Regulus® control system helps operators monitor and optimize compressor performance.
These design choices support a practical maintenance strategy for equipment your facility depends on.
Optimize Compressor Performance
Regulus control systems provide intuitive control and real-time visibility into compressor performance, helping operators monitor critical data and respond to changing plant conditions.
Advanced control capabilities simplify operation, support efficiency, and provide the information needed to maintain reliable compressor performance.
Turn Compressor Heat Into Energy Savings
The Polaris P750 supports heat of compression (HOC) drying technology, using heat generated during compression to help dry compressed air. By reducing the energy required for air drying, HOC technology can help improve overall system efficiency and lower operating costs.
Long-Term Support You Can Count On
FS-Elliott supports customers throughout the life of their centrifugal compressor with a standard two-year bumper-to-bumper warranty. For added protection, our optional SteadiAIR® extended warranty provides three additional years of airend coverage, extending protection to a total of five years. Our factory-trained channel partners and global service network provide expert maintenance, technical assistance, and ongoing support.
Our Rapid Response Storage Center provides quick access to replacement airends when needed, while FS-Connect delivers added insight into compressor operation and performance.
From commissioning and service to parts, technical support, and long-term equipment needs, we’re here to help keep your compressor performing reliably for years to come.

Discover How to Use Heat Recovery to Cut Your Energy Costs
In industrial operations, compressed air plays a vital role across a range of manufacturing processes. As air undergoes compression, its moisture content rises significantly. Air compressor manufacturers use intercoolers and aftercoolers to remove much of the water from the air stream to address this. Still, the coolers alone do not remove enough moisture for some applications, and an external dryer, particularly heat of compression (HOC) dryers, become critical.
