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 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.

 Nx 15-75 kW Features


Designed for quiet operation.

  • Integration of centrifugal blower and drive motors make for extremely smooth and quiet operation
  • Extra-thick sound insulation reduces noise
  • Can be installed in applications where a quiet setting is important


The ultimate in system protection and reliability.

  • Protects critical components from compressor-generated heat
  • Extends component life and reduces downtime
  • Compartmentalized air flow design and standard aftercooler


Built to the highest levels of dependability and reliability.

  • Standard TEFC motor protects compressor from surrounding dirty air, increasing the efficiency and prolonging the life of the motor.
  • Spin-on air/oil separator allows for quick maintenance and results in one-to-three PPM oil carryover. This
    translates into lower make-up oil costs and higher quality compressed air.


Designed for low cost of ownership and easy service.

  • Space-saving design
  • Pulsation-free air
  • 100% continuous duty
  • Extended service intervals
  • More CFM per horsepower
  • Improved air quality
  • Energy efficiency at full load delivers more air for the mone integrated into a smaller footprint
  • Exclusive FS-Curtis airends utilize the latest rotor profile to maximize efficiency

Optional DemandSmart Energy Management System (15-75 kW)

Ideal combination of variable speed drive, controller, and drivetrain.

  • The VSD – time proven directly coupled design – offers faster response and greater operational efficiency
  • Variable operation slows airend speed, which lowers energy costs and reduces wear
  • With DemandSmart technology, the VSD enhances quality by stabilizing air pressure at 1 psi increments
  • Built-in DC Choke protects against harmonic disturbances and eliminates the need to source additional corrective devices
  • iCommand Controller is intuitive and easy to use while precisely delivering compressed air usage
