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 manufacturing facilities.
dBA Shield Noise Reduction
Designed for quiet operation. Operating at just 74 dBA at 125 PSI, the NxB30 can be installed in work environments where noise control is critical. Advanced engineering delivers whisper-quiet performance that won't disrupt your workspace.
- Integration of centrifugal blower and drive motors make for extremely smooth and quiet operation
- Extra-thick sound insulation reduces noise output to a fraction of traditional compressors
- Can be installed in applications where a quiet setting is important, including offices, clean rooms, and shared workspaces
- Laminated oil-proof sound insulation provides lasting acoustic protection
eCool® Technology — A Cool Innovation
Compressors generate heat. FS-Curtis' exclusive eCOOL technology provides protection from heat and reduces thermal stress on every critical component in your compressor system.
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 aftercooler maximize cooling efficiency
- Air cooled oil cooler & aftercooler provide reliable thermal management
