15-50 hp Belt Drive Compressors

QSB rotary screw compressor QSB Airend


The very user-friendly QST and QSB series of rotary screw air compressors from Quincy Compressor are equipped with large-diameter, high-efficiency rotors. Large rotors mean the QST and QSB can run at slower speeds for extended airend life and quiet, economical operation. For added economy, these units feature a continuous run, “load/no load” control system.
