Abstract: PURPOSE:To make it possible for an air current to uniformly blow off from a ceiling blow-off surface and to drop perpendicularly therefrom to form a laminar flow by constituting the floor surface into a dual structure of a porous floor surface and a floor surface with a damper disposed at the lower part of the porous floor surface, and disposing a suction duct at the lower part of the floor surface with the damper. CONSTITUTION:An under floor chamber 32 is formed at the lower part of a grating 14, and further a dual floor chamber 34 is formed at the lower part of a floor 30 with a damper. A suction port 20 of an exhaust duct 18 is opened within the dual floor chamber 34. The speed of an air current blasted from a ceiling surface 10 is measured by air flow speed sensors 24 provided at a plurality of positions. A controller 28 delivers signals to respective drive motors 38 so that the speed of the air flow becomes constant at a predetermined height on the floor by the air flow speed sensors 24, and the opening degree of each damper 36 is adjusted and the suction air flow speed on the grating surface is made constant. When the air flow speed on the suction surface of the grating 14 becomes constant, the air flow speed at the predetermined height on the floor surface of the grating becomes constant, and the entire air current within the chamber 13 in the clean room forms a laminar flow.
