PURPOSE:To use simultaneously air shower booths by a number of operators by a method wherein at the air shower booths such as clean rooms, etc., a space is formed into a cylindrical structure and radial partition plates are installed on a circular floor so as to be rotatable together with the floor. CONSTITUTION:An operator enters a single booth partitioned by partition plates 14 from a gap between a shielding plate 15 and a pressurized chamber 12 and the plates 14 are gradually rotated together with a grating 8 by the rotation of a shaft 1 supported at a ceiling 2 through bearings 5 and when the booth arrives at the location of a gap D located at the opposite side of the gap C, the operator enters a clean room. During that time, dust on the operator is removed by clean air ejected from ejecting ports 13 and the got rid of the dust is sucked in by a compressor 9 and is cleaned by a filter 10 and then circulated. Thus, a number of operators can use the booths simultaneously and polluted air outside the clean room can be prevented from intruding into the clean room.
