When compressed air of m2 to 10 kg/cm2 is blown into the air, the pressure of the high-pressure compressed air drops rapidly, causing adiabatic expansion and rapidly lowering its temperature. From this, the temperature is lowered to the cooling fin (2) in the expansion chamber. Also, the moisture present in the compressed air comes into contact with (2), which has dropped in temperature, and condenses and adheres to (2). Therefore, dry air from which moisture has been removed is extracted from (6) and used. (4) is the drain (5) is the pressure adjustment valve (7).
