PURPOSE:To stabilize painting quality, by disposing wind speed sensors which detect wind speeds in vertical and horizontal directions to the respective zones of a painting chamber of a tunnel type divided to the plural zones and providing a control device to specifically control a discharge system in accordance with the wind speed values detected by said sensors. CONSTITUTION:The wind speeds in the vertical and horizontal directions are detected by the wind speed sensors 21a, 21b respectively provided to the respective zones 2a, 2b in the painting chamber 1. The zone where the oblique flow synthesized of the vertical flow and horizontal flow is max. is selected in accordance with the detected wind speed values. For example, discharge control is executed by as much as a set value by a discharge fan 10a if the oblique flow of the zone 2a is large. The horizontal wind speed value of the zone 2a after the control is then measured. Whether the horizontal wind speed value of the zone 2b is adequate or inadequate is judged if the measured value is below the set value. The discharge control is shifted to the zone 2b if said value is not below the set value. The discharge quantity is thus controlled successively until the horizontal wind speed values of all the zones decrease to the set value or below.
