Quincy Air Compressor 50 HP Tankless Rotary Screw 230/460V 3 Phase
Quincy 4152016900 QGS 50-HP Tankless Rotary Screw Air Compressor (230/460V 3-Phase)
The Quincy QGS 50-HP tankless rotary screw compressor offers exceptional performance with its gear-driven system, eliminating belts to reduce transmission losses and maintenance demands. Designed for heavy industrial applications, this unit runs on a 100% duty cycle with a TEFC motor featuring a wye-delta reduced voltage start for efficient operation.
Its Infologic2 Basic Controller allows programming and networking of up to six QGS units for scalable air solutions. The user-friendly display panel provides clear readouts of pressure, temperature, and dewpoint, while auto-run and alarm indicators keep your operations informed. Premium synthetic lubrication ensures up to 8,000 hours of runtime with low oil carryover, safeguarding critical components.
Quiet operation is achieved with a full sound enclosure, minimizing workplace noise and vibration. Maintenance is simplified thanks to hinged doors, detachable panels, constant fluid monitoring, and spin-on fluid filters for fast service. The compressor ships in 460V-3 with a kit included for 230V-3 wiring, requiring installation by a licensed electrician.
