PURPOSE:To make smooth the flow of air by feeding the air to an air duct and diffusing the air at an air guide after the air has passed through a filter. CONSTITUTION:When an open air fan 53 is driven as an air supply fan, the air is supplied from one end of an open air duct 33 in the longitudinal direction to the other end. The air current in the air duct 33 is consecutively collided against a guide plane of an air guide 40 from one end of the air guide 40 to the other end. Along the guided plane, the air direction is changed to a filter 35, crossing the longitudinal direction of the air duct 33 on the slant and passes through the filter 35. As a result, the air pressure in a wind furnace 33 is diffused not only on the other end in the longitudinal direction but also at the position of the air guides given at some interval longitudinally. This construction makes it possible to equalize the air pressure in the air duct 33 and the air quantity passing through the filter 35 and its air velocity at each space in the longitudinal direction and smoothen the air flow of the lower current from the filter 33 and supply the air conditioned air into a booth efficiently. |
