NX Series Rotary Screw Air Compressors (Fixed & Variable Speed)

The FS Curtis NX Series Rotary Screw Air Compressors are industrial-grade compressed air systems engineered for continuous duty performance, energy efficiency, and long-term reliability. Available in both fixed speed and variable speed (VSD) configurations from 15 to 90 kW, the NX Series is designed to meet diverse plant air demand profiles.

The compressors feature high-efficiency rotary screw airends optimized with precision rotor profiles to deliver stable airflow with minimal specific power consumption. Direct drive transmission ensures loss-free power transfer, reducing mechanical wear and improving operating efficiency.

NX Series units are equipped with premium efficiency motors, centrifugal cooling fans, and oversized heat exchangers delivering superior thermal management. FS Curtis’ exclusive eCOOL™ cooling technology utilizes compartmentalized airflow design and optimized ventilation paths to reduce internal heat load, extending component life and improving overall reliability.

Integrated oil separation systems maintain low oil carryover levels, ensuring clean compressed air output. Intelligent AIMS Plus controllers provide real-time monitoring, pressure control, maintenance alerts, and remote communication via RS485 Modbus interface.

Optional DemandSmart™ energy management system with VSD technology dynamically matches compressor output with plant air consumption, significantly reducing unload losses and lifecycle operating costs.

Compact enclosure design enables low noise operation, easy service access, and space-saving installation, making the NX Series ideal for automotive, engineering, FMCG, plastics, textiles, and process industries.
