PROBLEM TO BE SOLVED: To provide an air supply/exhaust system in which a more stable air curtain flow can be formed at a low cost regardless of the size of ventilation area by providing a hood for regulating the final blowing direction on the outer circumference of an air outlet and selecting the size of the hood arbitrarily thereby eliminating the need for altering the duct dimensions or the dies and enhancing versatility. SOLUTION: The air supply/exhaust system comprises an intake hood 10 having an air inlet 10a for sucking/exhausting air in a specified local area on the lower side, and a supply hood 4 having an air outlet 3 for blowing air to the outer circumference of the intake hood 10 wherein a hood 1 for regulating the final blowing direction of air flow having a size corresponding to that of the area being exhaust is disposed on the outer circumference of the air outlet 3 independently from the supply hood 4. |
