A water release system includes a compact aftercooler connected to receive hot, moisture laden compressed air from a compressor having a load cycle under control of a governor. A water release valve is connected between a header of the aftercooler and an unloader pressure line connected to the governor. The valve ordinarily remains open until it receives a certain, pressure value signal from the unloader line which is effective to close the valve. A switch is located in pressure sensing relationship with the aftercooler, and a solenoid valve is electrically connected to the pressure sensitive switch and pneumatically connected between the water release valve and the governor. When the pressure sensed by the switch is somewhat above that at which the water release value ordinarily closes, the pressure sensitive switch closes to energize the solenoid valve and thereby open the same, after which the water release valve operates automatically to open and close in response to pressure and lack thereof in the unloader line.
