ABSTRACT:
A method and apparatus provide multiple consecutive purges of an air dryer in a vehicle compressed air system. A dryer throughput sensor has an output indicative of the amount of compressed air that is passed through the dryer. In response, a CPU determines the number of purges needed to purge the dryer; and a valve is operated by the CPU to initiate multiple purges of the dryer when the compressor is unloaded.
