An improved air drier adapted for drying humid air is equipped with a cylinder shaped shell having a conical water collecting bottom and a duct disposed therein which is provided with an air outlet tube through the center thereof; and the outer wall of the duct helically wound with the elongated condensing tube in which the coolant of a condenser circulates is helically disposed a continuous partition board in correspondence to the wound condensing tube; the periphery of the continuous partition board is not in contact with the inner wall of the cylinder shaped shell with a drain space defined therebetween so as to permit the water condensed from the moisture in the humid air can drip down therefrom to the water collection bottom. The dried air is then led through the outlet tube to the outside. The present air drier is characterized in that humid air is pumped into the cylinder shaped shell by a pump and further led through the helically wound partition baord at such a speed whereby moisture particles and other dirt particles can whirl therethrough and collide against the inner wall of the shell and the outer wall of the duct so that air can be better filtered and condensed.
