PURPOSE:To prevent dusts falling off of workers from depositing on products by disposing a localized air drawing hood under the ventilating plate so as to raise the local air speed. CONSTITUTION:Directly under the ventilating plate 5 of work area, a localized air drawing hood 12 is disposed, which is connected to the duct 13 that has at its end a ventilating fan 14. By this arrangement, the air blowing speed in the work area becomes 1.5-2 times faster than that of other floor area. The air flow that hits the worker is drawn downward directly. Since the air flow over the work table 11 is directed toward the worker, dusts falling off of the worker are quickly expelled under the floor without depositing on the product placed on the work table 11, preventing the dust deposit on the product. |
