An air distribution apparatus in a paint spray booth plenum for increasing the uniformity of down draft velocities from the plenum to the spray booth paint application zone. The increased uniformity of down draft velocities correspondingly increases paint transfer efficiency and minimizes paint overspray buildup in the paint application zone. The improved air distribution apparatus includes airflow regulating elements and flow directing members which cooperate to distribute airflow substantially evenly across the plenum floor and into the paint application area. In the preferred embodiment, a plurality of perforated plates and guide vanes are used to control the rate and direction of airflow in the plenum. The invention also provides for the adjustment of the rate and direction of flow through the use of slidable plates and adjustable guide vanes.
