The NXD75 is available in 100, 125, 150, and 175 PSI configurations, producing up to 495 CFM, and features FS-Curtis eCOOL® Technology, a premium-efficiency TEFC motor, heavy-duty filtration, and iCommand-Touch+ controls.

Full Product Description

The FS-Curtis NXD75 100 HP Rotary Screw Air Compressor delivers the airflow, durability, and efficiency required for large industrial compressed air systems. Designed around a rugged direct-drive system, the NXD75 transfers motor power directly to the airend while minimizing moving components, helping reduce vibration, maintenance requirements, and long-term operating costs.

FS-Curtis equips the NXD75 with its precision-engineered helical twin-screw airend, premium-efficiency TEFC IP55 main motor, centrifugal cooling fan, and eCOOL® Technology. The intelligent internal layout improves cooling airflow throughout the compressor package while helping protect critical components from compressor-generated heat. nxd-15-37-brochure-02.26.26

The NXD75 is designed for 100% continuous-duty industrial operation and is available in four operating pressure configurations from 100 PSI through 175 PSI, allowing the compressor to be matched to the pressure and airflow requirements of your facility.
