Rotary Screw Air Compressors
FS-Curtis

Our award winning rotary screw air compressors are available from 5HP to 350HP with variable speed options as well as single stage and the most energy efficient two-stage technologies. At peak performance, our rotary screw compressors operate at 100% duty cycle.

Nx Series 4-37kW

4-37kW FIXED SPEED (VARIABLE SPEED AVAILABLE IN 8-37KW)

Compact in design, robust in power, the NX’s smooth, quiet operation is ideal for a wide variety of applications ranging from auto body shops to light industrial.

High-Performance, Legendary Reliability

Stable air pressure, steady airflow and quieter, continuous-duty operation are just a few of the advantages you get with FS-Curtis rotary screw air compressors. These smart, compact units also offer better air quality with less oil carryover than reciprocating models. Intuitive controls and diagnostics make them easy to use and service, too. It all adds up to an extremely reliable machine that can run 100% continuous duty, delivering more airflow and better efficiency in a space-saving design — making the NX Series ideal for automotive, light industrial and other applications that require reliable performance in demanding conditions.

NXHE Series Two-Stage 90-260kW

90-260kW DIRECT ROTARY SCREW AIR COMPRESSORS

Our most energy-efficient air compressor to date, the NXHE Series compressors use patented two-stage airend technology to provide efficient operation with outstanding durability and offer the lowest life-cycle cost of any compressor on the market.

TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY

Compared to single-stage compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency.

Two-stage air compressors are closer to the ideal isothermal compression:
• Reduced leakage increases volumetric efficiency
• Saves 10-15% of energy compared to single-stage compressors
• Increases flow 10-15% compared to single-stage compressors
• Lower pressure differential increases efficiency and reliability
• Low heat load
• Easy maintenance and service
• Lowest life-cycle cost of any compressor on the market
