A duplex air compressor, like almost all two stage compressors, has an air tank, electric motor and a pump.
A duplex compressor has two equal sized pumps and motors. For example, a 10 HP duplex air compressor would have two 5 HP air pump and motor units.
The advantages of having two motors and pumps are as follows:

Failure – If one of the pumps or motors was to fail, the operator would still have a working air compressor, all be it producing half the power. This, however, may be enough to keep the business operating whilst spare parts are ordered.

Power Supply limitations – If your business requires a higher powered compressor, ie 10 -15HP and a three phase power supply is not available. Two pump/motor sets on a duplex compressor can be run on single phase electrical supplies to supply the desired power

Air demand – When running some tools, you may not require full air flow, CFM, of say a 15 HP compressor. Occasionally you may then need to run a tool with higher air demand such as a Plasma Cutter. The duplex compressor would only run one motor when a smaller air demand is required and both motors would run when a higher demand is needed.
