NxB04

FS-Curtis NxB04 is a 5 HP fixed-speed rotary screw compressor delivering approximately 22 SCFM at 125 PSI, with optional 175 PSI variants and 60-gallon tank-mount or base-mount configurations. NxB is FS-Curtis’s industrial fixed-speed line, the smallest entry in the broader Nx family that scales up through 22, 30, and 37 kW. The headline differentiator is the NXGEN 10-year airend warranty, which is among the longest in the industry when shop fluids and filters are used to spec. The package includes a precision-machined screw airend, premium-duty TEFC motor, V-belt drive, microprocessor controller, and integrated air-cooled aftercooler. Best for small but continuous-air shops, single-bay autos that thermal-trip pistons, woodworking studios, and lab spaces. Three-phase 208/230/460V is standard. FS-Curtis is the modern brand for what used to be Curtis-Toledo, a 170-year-old American compressor maker, with strong dealer support and parts availability.
