The Quincy QT Splash Lubricated Duplex Air Compressor is a heavy-duty industrial 2-stage duplex air compressor system that protects your business from expensive downtime! The duplex compressor includes two QT splash-lubricated compressors and two motors mounted on an ASME horizontal tank. Each system can be run independently or together, should your air demand require it. Works in applications from intermittent-duty to 100% duty requirements. 1-year limited warranty without extended warranty kit purchase. Purchase two extended warranty kits (Item# 42637, one for each compressor) at the same time (on the same receipt) as your Quincy 120-gallon duplex 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 (parts and labor).
