ABSTRACT:
An air diffuser for a modular drop ceiling construction in which an annular discharge opening is defined by the inner margin of the ceiling framework members forming a square or rectangular opening and the outer margin of a ceiling panel positioned concentrically in the opening and suspended at the corners from the framework. Air is directed by a conduit and hood against the backside of the ceiling panel and directed outwardly through the rectangular annular space around the margin of the panel. Lateral airflow outwardly from the diffuser along the adjacent ceiling is provided by shaping the margins of the opening to provide either a beveled or step outline in cross section.
