PROBLEM TO BE SOLVED: To provide a clean booth for switching a positive pressure and a negative pressure without individually disposing a negative pressure source and a positive pressure source. SOLUTION: This clean booth includes an air unit device, a surrounding body and a frame assembly supporting the surrounding body. The air unit device includes a housing having both faces standing upright, a suction opening formed on one of both faces and a supply opening formed on the other face of the housing, an air passage communicating both openings in the housing, and an air distribution source for producing the airflow from the suction opening toward the supply opening along the air passage, and a filter for purifying the air from the suction opening, respectively disposed in the air passage. The surrounding body includes a ceiling face section and a peripheral wall section, and defining a booth chamber at its inner part, and the peripheral wall section constitutes a peripheral wall of the booth chamber with one of both faces of the housing. The frame assembly supports the surrounding body to be selectively disposed at one side of both faces of the housing. COPYRIGHT: (C)2011,JPO&INPIT
