"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 best-in-the-industry 50,000-hour pump life rating. Purchase an extended warranty kit Item# 42637 at the same time on the same receipt as your Quincy air compressor and register online within 10 days of receipt, and it will double the package warranty to 2 years and triple the pump warranty to 3 years on-site parts and labor included.
