The Quincy QSI is designed to take on applications that require full airflow capacity in harsh operating conditions, such as hot, cold, dirty or outdoor environments. Rotary screw compressors like the QSI are useful in many industries:
Our rotary screw QSI compressors exhibit high operational efficiency and performance by producing an output of 100-175 pound-force per square inch (psi) and an airflow volume of 220-2,011 cubic feet per minute (CFM). These single-stage oil-injected compressors feature sound-insulated bodywork and a gearbox driven by a powerful electric motor. The gearbox includes a microprocessor control system so users can adjust system performance without the need for complex codes.
