The FS-Curtis NxB18 delivers industrial-grade performance in a compact, efficient package. This 25 HP rotary screw air compressor is designed for 100% continuous duty operation, providing stable air pressure, steady airflow, and remarkably quiet performance. Whether you're running an automotive shop, light industrial facility, or any operation demanding reliable compressed air, the NxB18 combines advanced engineering with Made in the USA quality to deliver more CFM per horsepower with better air quality than traditional reciprocating compressors.
Featuring eCool® Technology, the iCommand Basic electronic controller, and a leak-free heavy-duty design, the NxB18 offers extended service intervals, intuitive diagnostics, and easy maintenance—all in a space-saving design. Available in multiple voltage and pressure configurations (100, 125, 150, and 175 PSI), with optional integrated dryer models, this compressor is built to meet your exact requirements.
Configuration Options
The NxB18 is available in two base configurations: the standard base-mounted unit and a base-mounted unit with integrated dryer. Both configurations offer flexibility with 230V or 460V three-phase power options and four pressure ratings to match your application needs.

dBA Shield Noise Reduction
Designed for quiet operation. The NxB18 operates at just 72 dBA at 125 PSI (69 dBA with integrated dryer), making it suitable for installations where a quiet setting is critical.
- Integration of centrifugal blower and drive motors make for extremely smooth and quiet operation
- Extra-thick sound insulation with laminated oil-proof material reduces noise significantly
- Can be installed in applications where a quiet setting is important, including shared workspaces and customer-facing areas
eCool® Technology
A Cool Innovation. Compressors generate heat. FS-Curtis' exclusive eCool® technology provides protection from heat and reduces thermal stress, ensuring your compressor runs cooler and lasts longer.
By combining smart compressor layout with intelligent component selection, eCool® technology maximizes cooling airflow for greater energy efficiency, improved reliability, and increases service life up to 50% longer for motors and electrical components and up to 30-50% longer for bearings, hoses, and seals.
The ultimate in system protection and reliability:
- Protects critical components from compressor-generated heat
- Extends component life and reduces downtime
- Compartmentalized air flow design with standard air-cooled oil cooler & aftercooler
- Maximizes cooling efficiency for the entire system
