Quincy Air Master 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 best-in-the-industry 50,000-hour pump life rating. MAX configuration features automatic tank drain, low oil shutdown and heavy-duty aftercooler included. 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).
