PURPOSE: An air dryer system is provided to reduce the breakdown rate of an air dryer and expand the replacing period of a filter by discharging oil of the air dryer at any time. CONSTITUTION: An air dryer system provides to an air brake system after removing water, carbon, and oil contained in compressed air which is flowed into a compressor. The air dryer system is composed of a valve seat unit(100) formed upward and a chamber unit(200) formed downward; a discharge outlet(21) for discharging oil remaining in a chamber and a discharge valve(22) for opening and closing the discharge outlet formed at the lower end of the chamber; a 2-way solenoid valve disposed to an air inflow pipe from a compressor to connect two air dryers in parallel; and a 2-way solenoid valve installed to the position at which an air outflow pipe flowing out from each air dryer is combined. Accordingly, two solenoid valves selectively operate one of the air dryers connected in parallel by switch-operations of a user.
