The variable speed compressors work to maintain a constant air pressure, while the motor speed is adjusted to meet the production of air required. In fact, variable speed machines can reduce engine revolutions and align with actual air demand, therefore saving energy.
Unlike variable speed air compressors, fixed speed compressors are either running at 100% or are off. They are ideal in applications where a constant demand for compressed air is needed. The machine works with the same number of engine revolutions, unless it is switched off. Fixed speed air compressors always run at full capacity and therfore could produce more air than required with a wast of energy.
