FS-Curtis NXB15UP 20 HP UltraPack Rotary Screw Air Compressor

The FS-Curtis NXB15UP compressor is a 20 HP fixed-speed complete UltraPack system: an air-cooled rotary screw air compressor mounted on an 80-gallon tank with an integrated refrigerated air dryer and particulate pre-filtration, built for demanding, continuous-duty industrial air. Rated for 77 CFM at 125 PSI, the NXB15UP pairs an exclusive FS-Curtis encapsulated helical twin-screw airend with premium controls and cooling for efficient, reliable shift-after-shift performance.

Backed by more than 170 years of FS-Curtis engineering and a nationwide network of factory-trained service technicians, the NX Series is FS-Curtis' premium rotary screw platform. It is a proven workhorse for manufacturing and assembly, automotive, woodworking, printing, packaging, textiles, laser cutting, and any plant that depends on clean, stable compressed air.

A complete, plug-and-play system: the NXB15UP arrives as a compressor, 80-gallon receiver tank, refrigerated dryer, and pre-filter on one skid, so you get clean, dry, regulated air from a single connection with minimal installation.
