Rotary screw compressors like the NxB04 outperform piston compressors in every key category: smoother operation, pulsation-free air, superior energy efficiency, and better air quality with less oil carryover. The NxB04 is compact in design yet robust in power, making it ideal for automotive body shops, light manufacturing, woodworking, and service operations that demand reliable compressed air in a space-saving package.

This machine features intuitive controls and diagnostics for easy operation and service, and is engineered with quality components to deliver a low cost of ownership over years of continuous use. Whether you're running spray guns, pneumatic tools, or automated equipment, the NxB04 provides the steady, dependable performance your operation requires.

dBA Shield™ Noise Reduction – Whisper-Quiet Performance

Designed for quiet operation at just 61 dBA at 125 PSI, the NxB04 can be installed in noise-sensitive environments without disruption. The compressor's advanced sound engineering includes:

Centrifugal blower and drive motor integration for extremely smooth and quiet operation
Extra-thick laminated oil-proof sound insulation reduces operational noise
Powder-coat painted enclosure seals in sound while protecting internal components
Ideal for installation in applications where a quiet setting is critical

eCool® Technology – A Cool Innovation for Longer Life

Compressors generate heat. FS-Curtis' exclusive eCool® Technology provides advanced protection from heat and dramatically reduces thermal stress on critical components. By combining a smart compressor layout with intelligent component selection, eCool maximizes cooling airflow, resulting in:

Greater energy efficiency and improved reliability
Up to 50% longer service life for motors and electrical components
Up to 30-50% longer life for bearings, hoses, and seals
Compartmentalized airflow design and standard aftercooler ensure optimal cooling
Protects critical components from compressor-generated heat, reducing downtime

The result? The ultimate in system protection and reliability. eCool Technology extends component life and keeps your compressor running at peak efficiency, year after year.
