The FS-Curtis NxB04 is a 5 HP rotary screw air compressor designed for professionals who demand reliable, continuous-duty performance in a compact footprint. Built with eCool™ Technology, this tank-mounted unit delivers superior cooling, whisper-quiet operation at just 61 dBA, and exceptional air quality with minimal oil carryover. Whether you're running an auto body shop, light industrial facility, or any environment where dependable compressed air is critical, the NxB04 offers the perfect balance of power, efficiency, and serviceability—all proudly made in the USA.
Featuring a rugged 60-gallon tank, a Premium Efficiency TEFC motor, and the intuitive iCommand Basic controller, this compressor is engineered for 100% continuous duty in demanding conditions. With available configurations in 230V single-phase and tri-voltage options across 100, 125, 150, and 175 PSI, you can tailor the NxB04 to your exact pressure and power requirements. Plus, the optional Ultra Pack adds an integrated dryer and filter for even cleaner, drier compressed air—protecting your tools and maximizing productivity.
Why Choose the FS-Curtis NxB04 Rotary Screw Compressor?
Rotary screw compressors offer distinct advantages over reciprocating models: stable air pressure, steady airflow, and quieter, continuous-duty operation. The FS-Curtis NxB04 takes these benefits further with advanced engineering and quality components that deliver better air quality with less oil carryover than traditional piston compressors. Intuitive controls and easy-access diagnostics make service straightforward, reducing downtime and keeping your operation running smoothly.
Compact in design, robust in power—the NxB04 is ideal for automotive, light industrial, and other applications that require reliable performance in demanding conditions. Its space-saving footprint and smooth, quiet operation make it perfect for environments where noise control and floor space are at a premium.
Designed for Quiet, Efficient Operation
Noise can be a major concern in busy shop environments. The NxB04 addresses this with intelligent design choices that minimize sound without sacrificing performance:
- Integration of centrifugal blower and drive motors ensures extremely smooth and quiet operation
- Extra-thick, laminated oil-proof sound insulation reduces noise to just 61 dBA
- Powder-coat painted enclosure with professional fit and finish
- Can be installed in applications where a quiet setting is essential, such as auto shops, retail spaces, and light manufacturing facilities
eCool® Technology: A Cool Innovation
Compressors generate heat—and heat is the enemy of reliability. FS-Curtis' exclusive eCool® Technology provides active protection from thermal stress, maximizing cooling airflow for greater energy efficiency, improved reliability, and significantly extended component life.
By combining smart compressor layout with intelligent component selection, eCool® technology delivers measurable benefits: up to 50% longer service life for motors and electrical components, and up to 30-50% longer life for bearings, hoses, and seals. This translates directly into reduced downtime, lower maintenance costs, and a compressor that keeps running when you need it most.
The ultimate in system protection and reliability:
- Protects critical components from compressor-generated heat
- Extends component life and reduces costly downtime
- Compartmentalized airflow design and standard aftercooler ensure efficient heat dissipation
- Washable cabinet pre-filter keeps cooling air clean and unrestricted
Quality Components for Long-Term Reliability
Built to the highest levels of dependability, the NxB04 features premium components chosen for performance and longevity:
- Premium Efficiency TEFC motor (IP55) protects the compressor from surrounding dirty air, increasing efficiency and prolonging motor life
- Encapsulated airend utilizing the latest rotor profile to maximize efficiency and airflow
- Spin-on oil filter and air/oil separator allow for quick, hassle-free maintenance
- Achieves one-to-three PPM oil carryover, delivering higher quality compressed air and reducing makeup oil costs
- Air-cooled oil cooler and multi-function oil valve for optimized lubrication and temperature control
- Built-in heavy-duty air intake filter protects internal components
