The FS-Curtis NxB15 delivers 20 HP of rotary screw performance engineered for 100% continuous duty in demanding automotive and light industrial environments. This base-mounted compressor combines space-saving design with eCool™ Technology and premium components to provide stable air pressure, steady airflow, and exceptionally quiet operation at just 69 dBA. Built in the USA with a leak-free design, premium efficiency motor, and factory-filled synthetic lubricant, the NxB15 offers better air quality, improved reliability, and extended service life—delivering more CFM per horsepower with lower maintenance costs and reduced downtime.


Why Choose the FS-Curtis NxB15?

Stable air pressure, steady airflow, and quieter continuous-duty operation are just a few of the advantages you get with FS-Curtis rotary screw compressors. These smart, compact units also offer better air quality with less oil carryover than reciprocating models—just one-to-three PPM thanks to the spin-on air/oil separator. Intuitive controls and diagnostics make them easy to use and service, too.

It all adds up to an extremely reliable machine that can run 100% continuous duty, delivering more airflow and better efficiency in a space-saving design—making the Nx Series ideal for automotive, light industrial, and other applications that require reliable performance in demanding conditions.

Compact in design, robust in power, the Nx's smooth, quiet operation is ideal for a wide variety of applications ranging from auto body shops to light industrial facilities.


dBA Shield Noise Reduction

Designed for quiet operation. The NxB15 can be installed in applications where a quiet setting is important—workshops, indoor facilities, and noise-sensitive environments.

  • Integration of centrifugal blower and drive motors make for extremely smooth and quiet operation
  • Extra-thick sound insulation with laminated oil-proof insulation reduces noise to just 69 dBA at 125 PSI
  • Allows installation where traditional compressors would be too loud

eCool® Technology: A Cool Innovation

FS-Curtis eCool Technology

Compressors generate heat. FS-Curtis' exclusive eCOOL™ technology provides critical protection from heat and reduces thermal stress on vital components.

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 and standard air-cooled aftercooler ensure optimal thermal management

Quality Components for Maximum Reliability

Built to the highest levels of dependability and reliability. Every component in the NxB15 is selected for longevity and performance.

  • Premium Efficiency TEFC motor (IP55 rated) protects compressor from surrounding dirty air, increasing efficiency and prolonging motor life
  • Spin-on air/oil separator allows for quick maintenance and results in one-to-three PPM oil carryover—translating into lower make-up oil costs and higher quality compressed air
  • Spin-on oil filter for easy, fast maintenance
  • Air-cooled oil cooler and aftercooler integrated into the eCool airflow design
  • Multi-function oil valve for superior lubrication management
  • Factory-filled synthetic lubricant for extended service intervals
  • Leak-free design with heavy-duty piping and O-ring seals eliminates waste

Superior Package Design

Designed for low cost of ownership and easy service. The NxB15 combines intelligent engineering with practical service access.

  • Space-saving design — compact footprint: 31" L x 26" W x 43" H (base unit)
  • Pulsation-free air for smooth, consistent delivery
  • 100% continuous duty operation
  • Extended service intervals reduce maintenance frequency and costs
  • More CFM per horsepower for improved efficiency
  • Improved air quality compared to reciprocating compressors
  • Energy efficiency at full load delivers more air for the money in a smaller footprint
  • Exclusive FS-Curtis airends utilize the latest rotor profile to maximize efficiency
  • Washable cabinet pre-filtration panels for easy cleaning and long filter life
  • Built-in heavy-duty air intake filter
  • Powder-coat painted enclosure for durability
  • Vibration isolators for smooth, quiet mounting

iCommand Basic Electronic Controller
