A painting facility, comprising:

• a sprayer for spraying paint downward is disposed at an upper portion of a painting structure defining a painting chamber;
• a painting robot;
• a robot installing chamber for installing the painting robot, wherein the robot installing chamber is disposed laterally adjacent the painting chamber;
• wherein an arm leading end portion of the painting robot is configured to hold a painting object that is painted by paint spraying from the sprayer while displacing the painting object relative to and downwardly of the sprayer by an action of the painting robot;
• an air feeding opening for the robot installing chamber is provided for directing ventilation air to the robot installing chamber;
• and
• by air feeding from the air feeding opening, the robot installing chamber is placed under a higher pressure than the painting chamber adjacent thereto, thereby to form an air flow which flows from the robot installing chamber into the painting chamber,
• wherein a sock filter for feeding ventilation air to an upper portion of the painting chamber and an air curtain air feeding opening for forming an air curtain which flows downward along a painting chamber lateral wall disposed opposite the adjacent robot installing chamber are provided at upper portions of the painting chamber,
• wherein downwardly of the painting chamber, there is formed an air discharging area for discharging downward air present inside the painting chamber,
• wherein the sock filter for discharging the ventilation air fed therein through a circumferential portion thereof is disposed under a horizontal posture at an upper portion of the painting chamber,
• wherein an air curtain air discharging box having the air curtain air feeding opening in a lower face portion thereof is disposed at an upper portion of the painting chamber in close vicinity of the painting chamber lateral wall, and
• wherein a leading end portion of the sock filter is connected to and opened into the air curtain air discharging box.
