dBA Shield Noise Reduction

Designed for quiet operation. The NxB11's advanced acoustic engineering ensures it can be installed in environments where noise control is critical.

  • Integration of centrifugal blower and drive motors delivers extremely smooth and quiet operation
  • Extra-thick laminated oil-proof sound insulation reduces operational noise to just 63 dBA at 125 PSI
  • Can be installed in applications where a quiet setting is important, including in-shop or near-office environments

eCool® Technology

FS-Curtis eCool Technology

A Cool Innovation. Compressors generate heat. FS-Curtis' exclusive eCool® technology provides superior protection from heat buildup and dramatically reduces thermal stress on critical components.

By combining smart compressor layout with intelligent component selection, eCool technology maximizes cooling airflow for greater energy efficiency, improved reliability, and extends 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 costly downtime
  • Compartmentalized air flow design with standard aftercooler ensures optimal thermal management

Quality Components

Built to the highest levels of dependability and reliability. Every component in the NxB11 is selected for maximum performance and longevity.

  • Premium Efficiency TEFC (IP55) motor protects the 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 fast, clean service intervals
  • Air-cooled oil cooler & aftercooler maintain optimal operating temperatures
  • Multi-function oil valve ensures proper lubrication under all conditions
  • Factory-filled synthetic lubricant for superior performance and extended intervals
  • Built-in heavy-duty air intake filter with washable cabinet pre-filtration panels
  • Wye-Delta motor starter and 115/18V control voltage transformer for reliable electrical operation
  • NEMA-1 electric panel protects electrical components in demanding environments

Superior Package Design

Designed for low cost of ownership and easy service. The NxB11 combines efficiency, performance, and maintainability in one intelligent package.

  • Space-saving design — fits where other compressors can't
  • Pulsation-free air for consistent, reliable performance
  • 100% continuous duty rating for demanding applications
  • Extended service intervals reduce maintenance costs and downtime
  • More CFM per horsepower — superior efficiency at full load
  • Improved air quality with minimal oil carryover
  • Energy efficiency delivers more air for the money, integrated into a smaller footprint
  • Exclusive FS-Curtis airends utilize the latest rotor profile to maximize efficiency
  • Leak-free design with heavy-duty piping and O-ring seals
