The Quincy QP Air Compressor’s fully pressure-lubricated system allows for smooth, continuous operation. This heavy duty, cast-iron compressor has an oil pump for pressure lubrication to the crankshaft, bearings and connecting rods up to the wrist pins. Pressurized oil flowing to all critical surfaces means less wear on the components. Spin-on filter lengthens pump life and improves reliability. Compressor also features low oil pressure shutdown, mounted air-cooled aftercooler, mounted electric automatic tank drain, start/stop control operation and more. The QP balances cost-effectiveness with longer life to maximize your investment, providing up to 15% longer life than a splash-lubricated compressor. Compressor comes with a 1-year limited warranty. An optional No Bull 3-year pump/2-year package on-site warranty is available when you buy the Item# 43106 extended warranty kit
