Abstract
An air dryer control system is disclosed in which the compressed air output of a compressor is dried by one of two air dryers connected in parallel. The purging and drying cycles of the air dryers are alternated by timing and relay device. Upon start-up, the output of the compressor is dried by both air dryers until the pressure level in the supply reservoir attains a predetermined level. When the governor cutout pressure is achieved in the reservoir, both air dryers are purged.
