Features & Benefits
A compressor’s value extends beyond its rated capacity. The Polaris P400 combines oil-free centrifugal compression with a compact, plug-and-play design, advanced controls, and accessible components to help your team improve efficiency, simplify maintenance, and support reliable long-term operation.
For high-pressure applications, the available P400 HPR delivers pressures up to 250 PSIG with three-stage compression designed to maximize efficiency and reduce energy consumption.
Confidence for Critical Air Demands
The Polaris P400 is engineered to deliver ISO 8573-1 Class 0 oil-free air with the reliability and efficiency required for demanding industrial applications.
Its oil-free air path helps protect processes from compressor oil contamination, while integrated monitoring and control 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.
Together, these maintenance-friendly features help reduce service time, improve equipment reliability, and support long-term performance throughout the compressor’s lifecycle.
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.
High-Pressure Air, Efficiently Delivered
For applications requiring higher discharge pressure, the optional Polaris P400 HPR configuration delivers up to 250 PSIG using three-stage compression. This high-pressure design helps facilities meet demanding compressed air requirements while supporting efficient operation.
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.

How Compressed Air Impacts Product Quality and Efficiency in Automotive Manufacturing
Automotive manufacturing relies on compressed air at virtually every stage of production. From robotic assembly and paint operations to material handling and battery manufacturing, compressed air powers critical processes that keep production moving.
Why Manufacturers Are Switching to Oil-Free Compressed Air
Compressed air is often called the fourth utility, but in many manufacturing environments, it also plays a direct role in product quality, operational efficiency, and regulatory compliance. That makes air quality more important than many facilities realize.
