Duplex Compressors

The CAS duplex compressor is designed to offer the extra reliability needed by some of the most demanding applications. The compressors are built on a single tank with two motors and two pumps. The compressors can run together or you can turn on just one unit when air usage is low. The time delay start built into every CAS duplex compressor saves on the high demand rate charged by the electric company by not allowing both units to start at the same time.When you need extra reliability and space savings a CAS duplex is the right compressor for your application.
