Variable speed air compressors provide potentially big energy savings. Along with no spike in amperage on start up due to a slow start, there is potential energy savings when your air demands vary during the work day.
Basically, the air compressor will only produce as much air as needed within a range. For example, if your demand is low, the air compressor will run at a speed that will produce the required CFM (Cubic Feet per Minute). If the demand picks up, the air compressor will speed up to hit that demand. By not always running at full speed, it does not require as much power to do the job.
