Air distribution arrangement for paint spray booth

In a paint spray booth including a paint application area, a plenum having a surface in fluid communication with the paint application area for feeding airflow thereto, and air receiving means for receiving air into said plenum, said plenum defining plenum chamber, wherein the improvement comprises:

• an air distribution arrangement including a flow directing member coupled to the plenum to define an air distribution chamber communicating with said air receiving means said air distribution arrangement further including a guide member projecting from said flow directing member, said guide member directing the airflow from said air distribution chamber into said plenum chamber and uniformly over said surface along a first direction;
• and
• a first and second array of perforated plates coupled to said plenum to communicate with the air receiving means, said first and second array of perforated plates creating a variable open area to regulate airflow from said air receiving means into said air distribution chamber.

In a paint spray booth including a paint application area, a plenum coupled to said paint application area and having a surface in fluid communication therewith for supplying airflow thereto, and air supply means for supplying air into said plenum, said plenum defining a plenum chamber, wherein the improvement comprises:

• an air distribution apparatus including a flow directing member coupled to the plenum to define an air distribution chamber communicating with said air receiving means, said air distribution apparatus further including a guide member projecting if from said flow directing member, said guide member directing air from said air distribution chamber into said plenum chamber, said guide member being positionable to control the direction of airflow entering said plenum chamber thereby creating a substantially uniform flow of air over said surface along a first direction;
• and
• a damper coupled to said plenum, said damper positionable to regulate airflow from said air supply means.
