Single Stage Units Stationary & Portable Compressors

A single-stage air compressor works by drawing air into the compressor’s cylinder, where it is then compressed with a single stroke of a piston and sent to a storage tank. This differs from a two-stage air compressor where, after the initial compression, the air is delivered to another high-pressure piston via a specially designed intercooler tube for a second compression. Depending on the model, a single stage air compressor can provide a pressure between 110 and 145 psi, while two-stage compressors can deliver up to 175 psi.

Quincy Single Stage Key Features

As the title indicates, single-stage air compressors work by pulling air into the machine’s cylinder and compressing it with one piston stroke. The compressed air then travels to a storage tank for future use in manufacturing and industrial operations.
