ABSTRACT OF THE DISCLOSURE A compressed air system includes an electronic control which controls enabling and disabling of the compressor in response to pressure level variations in the system storage reservoir. The control unit responds to compressor disabling by causing the system air dryer to regenerate or purge for a predetermined time period, even if the compressor is unloaded for time periods greater than the predetermined time period. If the compressor comes back on load before expiration of the predetermined times period, purging of the air dryer is immediately discontinued. Accordingly, the air dryer is never purged for long periods of time, thereby conserving the desiccant used in the air dryer, and also increasing the efficiency of the engine which operates the air compressor, since turbocharged engines normally communicate the output of the turbocharger to the air compressor, and venting a portion of the turbocharger for long periods of time can significantly decrease engine efficiency.
