Abstract
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. The timing period of a charge timer is initiated when the compressor is enabled. When the charge timer has timed out, the compressor is disabled and the air dryer purged for the predetermined time period.
