PROBLEM TO BE SOLVED: To provide an air shower device of high dust removing efficiency capable of obtaining a dust removing effect in a wide range with simple constitution. SOLUTION: The air shower device has a plurality of blowoff devices installed in an air shower room and changed in the air current direction of blowoff parts utilizing a wall surface effect. The blowoff device is composed of an air inflow port part, a hollow duct part and the blowoff part. A nozzle inflow port for air inflow is provided with a circular arc part, and an opening on the blowoff part inlet side is made larger than the air inflow port part to provide level difference between the air inflow port part and the blowoff part inlet side. The hollow duct part of the blowoff device is formed in hollow shape with a hole provided in the center part, and disposed in a perpendicular direction to the blowoff direction of air. The blowoff part of the blowoff device is formed in tapered shape and structured to be enlarged in the blowoff direction of air, and the blowoff port of the blowoff device and a wall surface in the air shower room are almost flush with each other.
