FS-Curtis NXB11 – 15 HP Fixed Speed Rotary Screw Air Compressor – Base Mounted
Short Description
The FS-Curtis NXB11 15 HP Fixed Speed Rotary Screw Air Compressor delivers up to 63 CFM at 100 PSI in a compact, quiet, continuous-duty package designed for automotive facilities, machine shops, fabrication, manufacturing, maintenance departments, and other industrial applications with steady compressed air demand.
The NXB11 is available in 100, 125, 150, and 175 PSI configurations and features a tri-voltage 208/230/460V, 3-phase electrical design, along with a choice of iCommand controls. FS-Curtis rates the NXB11 at 63.0 CFM at 100 PSI, 58.0 CFM at 125 PSI, 49.6 CFM at 150 PSI, and 44.6 CFM at 175 PSI.
The base-mounted configuration is ideal for installations using an existing air receiver or where the receiver, dryer, and filtration will be separately sized for the compressed air system.
Full Product Description
The FS-Curtis NXB11 15 HP Fixed Speed Rotary Screw Air Compressor is designed for businesses that need dependable compressed air throughout the workday and have moved beyond the practical limits of a reciprocating compressor.
Powered by a 15 HP / 11 kW motor, the NXB11 provides strong airflow across four available pressure configurations. At 100 PSI, the compressor delivers 63 CFM, making it an excellent fit for multiple pneumatic tools, CNC equipment, manufacturing machinery, fabrication equipment, and other applications with sustained air demand.
The NX Series combines an enclosed rotary screw compressor package with FS-Curtis technology designed for quiet, efficient, continuous-duty operation. FS-Curtis describes the series as providing stable air pressure, steady airflow, reduced oil carryover, intuitive controls, and 100% continuous-duty capability.
This base-mounted NXB11 is supplied without an air receiver, allowing the compressor to be connected to an existing receiver or paired with a separately sized vertical or horizontal tank.

Key Features & Benefits
15 HP Fixed-Speed Rotary Screw Design
Designed for applications with relatively consistent compressed air demand where a fixed-speed compressor provides a simple and dependable solution.
Up to 63 CFM
The NXB11 delivers substantially more airflow than smaller 7.5 and 10 HP machines, making it a strong choice for growing shops and industrial applications.
Four Pressure Configurations
Select 100, 125, 150, or 175 PSI based on the pressure requirements of the equipment being supplied.
NEMA Premium Efficiency TEFC Motor
The enclosed IP55 TEFC motor helps protect the motor from dust, dirt, and airborne contaminants found in industrial environments.
Helical Twin-Screw Airend
The NX Series uses rotary screw compression to provide steady, pulsation-free airflow for continuous-demand applications.
V-Belt Drive
A proven V-belt drivetrain provides reliable power transfer while allowing straightforward service.
Quiet Enclosed Package
The powder-coated enclosure incorporates removable panels and sound-control features to help reduce compressor noise while keeping service components accessible.
Full Synthetic Lubricant
The NX platform uses full synthetic lubricant with an 8,000-hour recommended change interval under applicable operating and maintenance conditions.
Service-Friendly Filtration
- Air/Oil Separator: Spin-on design with up to 4,000-hour interval
- Oil Filter: Spin-on design with up to 2,000-hour interval
- Air Filter: Heavy-duty design with up to 2,000-hour interval
Base-Mounted Flexibility
The compressor package is mounted on a steel base instead of an air receiver, allowing you to choose the receiver size and air-treatment equipment that best match the application.
Benefits
Built for Continuous Air Demand
The NXB11 is designed for operations where compressed air is an essential part of daily production. The rotary screw design provides consistent airflow without relying on the frequent start-and-stop cycling associated with traditional piston compressors.
More Air for Larger Applications
With 63 CFM available at 100 PSI, the NXB11 can support significantly greater air demand than smaller shop compressors.
Match Pressure to the Application
Operating at unnecessarily high pressure costs airflow and energy. The four available pressure configurations allow the compressor to be matched more closely to your actual equipment requirements.
Quiet Operation
FS-Curtis publishes a sound level of approximately 66 dBA for the NXB11, helping make it suitable for installations where excessive compressor noise is undesirable.
Flexible System Design
Because this is the base-mounted model, you can configure the complete compressed air system around the compressor instead of being locked into a predetermined receiver or dryer package.
