A gas compression system is operable to deliver a flow of compressed gas to a point of use. The gas compression system includes a compressor that is operable to produce a flow of compressed gas at a first pressure, a motor operable to drive the compressor at a compressor speed, and a gas treatment member positioned to receive the flow of compressed gas from the compressor and deliver the flow of compressed gas to the point of use at a second pressure. A controller is operable to vary the compressor speed in response to a difference between the first pressure and the second pressure.
