FS Curtis NXHE Series 125-350HP Two-Stage Rotary Air Compressors 90-260kW

NXHE Series Two-Stage Rotary Screw Air Compressors

Engineered for demanding industrial environments, the FS-Curtis NXHE Series delivers unmatched reliability and exceptional energy efficiency. Built with advanced two-stage rotary screw technology, the NXHE compressor divides the air compression process into two distinct phases — removing the heat of compression between stages to achieve superior performance and lower power consumption.

By splitting compression into two stages, the NXHE reduces the compression ratio in each phase, decreasing thrust loads on the bearings and dramatically extending airend life. The result is more air output with less horsepower, lower operating costs, and consistent performance you can count on for years of continuous service.

Ideal for high-flow, base-load industrial applications, the NXHE Series combines innovation, efficiency, and durability in one powerful package.

Key Advantages:

• Higher output per horsepower — produces more ACFM while allowing for a smaller compressor size and reduced energy demand.

• Superior efficiency — lower specific power and higher isentropic efficiency than single-stage models translate directly into power savings.

• Extended airend lifespan — reduced compression ratios minimize bearing loads and wear, ensuring long-term reliability.

• Enhanced cooling performance — an over/under design with inter-stage cooling eliminates heat of compression for improved efficiency.

• Independent bearing lubrication — delivers precise oil flow to critical wear points, protecting vital components and maximizing service life.

Recognized for its innovation and performance, the NXHE Series Two-Stage Rotary Screw Air Compressor earned the 2020 Plant Engineering Product of the Year – Gold Award in the Compressed Air category.
