Quincy reciprocating air compressors are designed to be a compressor for life. They are built for efficiency and lower operating costs, producing more compressed air at a lower horsepower. They run at a slower RPM, run cooler and cost less to operate. Heavy-duty compressors are engineered for industrial applications and boast a 50,000-hour rating for pump. You must specify Voltage (200/208, 230 or 460) when ordering. One-year limited warranty without extended warranty kit purchase. Purchase an extended warranty kit (Item# 43091) at the same time (on the same receipt) as your Quincy 120-gallon air compressor and it will double the package warranty to 2 years and triple the pump warranty to 3 years (parts and labor).
