A Compressor with an integral VSD can handle the constant loads for an extended period of time (running at close to 100% duty cycle), but it can also run at slower speeds to accommodate lower air demands at other times of the day.

Variable Speed Drives can reduce the overall energy costs associated with operating the Compressor Unit by simply controlling the speed of the Motor and Air End to match consumption. As Rotary Screw Compressors using the variable speed technology match the varying air demands and therefore have the ability to impact your energy consumption, some energy providers have offered rebates when these Units are purchased.
