ABSTRACT:
An automatic air compressor drain device which is enabled and disabled by the control of a timer to turn on a solenoid for guiding the air from the air tank of an air compressor into the drainer, where the force of the compressed air pushes up the piston central shaft to open up the water inlet and allow automatic drain by the air tank, and to close up the drainer inlet when the piston central shaft is pulled down by spring load force to complete the cycle of automatic drain.
