Paint spray booth plenum module

摘要

A plenum for a paint spray booth including at least one improved plenum module having a pair of side walls and a pair of end walls each comprised of a truss adapted to cooperate with a plurality of stilts thereby independently supporting the plenum above the paint application zone of a paint spray booth. The improved plenum module permits the spacing between plenum stilts to be increased to at least sixty feet thereby decreasing construction costs, increasing the uniformity of airflow from the plenum and decreasing the potential for air leaks from and into the plenum. The improved plenum modules are adapted to be coupled in series and in parallel to provide plenum modules of varying lengths and widths.
