The QSI Series is a rotary screw compressor that combines around-the-clock dependability with one of the most efficient airends in the industry. Oversized rotors, low RPM, and the patented Power$ync controller option, ensures maximum air production using minimal horsepower which equals bottom line productivity. While rated at 100 PSIG full load pressure as standard, the QSI series can also be operated at 110 PSIG without increasing the motor size. Oversized coolers allow continuous operation in ambient temperatures up to 115 degrees F. The QSI is an extremely versatile package that can be specially modified to meet almost any individual requirement.
