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. 2-year limited warranty (5-year limited warranty on pump if customer purchases and uses maintenance kit.)
