Duplex oilless piston air compressors with tank combine a powerful, low-maintenance oilless piston compressor with two same-sized pumps and motors mounted atop an air tank. The two motors and pumps in duplex compressors can run at the same time, giving them a higher output than single-motor (simplex) compressors, or they can be run one at a time providing redundancy in case one fails, making them ideal for critical compressed air applications.
