Description

High Performance, Legendary Reliability

Delivering stable air pressure, consistent airflow, quiet operation, and continuous full-capacity performance—these are just some of the benefits of FS-Curtis rotary screw compressors. Beyond these features, they also offer advanced system intelligence, superior air quality with reduced oil contamination, and the AIMS Plus Intelligent Controls, which monitor critical systems such as the motor for simplified operation and maintenance.

These compressors are industrial-grade machines you can rely on for 100% continuous operation, offering maximum energy efficiency thanks to FS-Curtis’ exclusive air-end, centrifugal fan, and other optimally sized components. That makes the Nx Series ideal for large-scale manufacturing and power generation industries.
