A method for protecting a compressor by reducing the differential pressure from the inlet to the outlet of the compressor by turbo-charging the inlet plenum of the compressor to reduce the normally present vacuum condition in the inlet, vacuum being simply a sub-ambient pressure. However, the inlet plenum is not increased to a pressure above ambient. Additionally by preventing a high vacuum condition from existing at the inlet plenum of the compressor by warning or even stopping the compressor if the vacuum reaches too great a level.
