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.
