An airflow distribution system for discharging air from a thin plenum chamber into a relatively larger space such as a discharge duct or the work chamber of an industrial oven. A distribution plate separating the chambers has discharge openings arranged in pairs, having diagonally oriented louvers sufficiently closely spaced to direct individual air streams toward one another where by combine as a resultant air stream flowing transversely outwardly from the distribution plate. The louvers are illustrated as circular or rectangular tabs partly punched from the plate in forming the discharge openings and are adjustable by bending to vary the direction and volume of the resultant air streams. Among the examples disclosed are industrial ovens and air discharge ducts.

An airflow distribution system comprising: an inlet plenum chamber, a discharge duct extending along a longitudinal axis intersecting said plenum chamber, and a fluid distribution plate forming a common wall therebetween; said plenum chamber having inlet and outlet means for directing a flow of fluid through the plenum chamber into the duct; said outlet means comprising a plurality of discharge openings in said distribution plate arranged in a predetermined array around said longitudinal axis, said plate having diagonal louvers secured to the edges of said openings, said louvers having substantially the same orientation relative to said longitudinal axis to thereby direct individual streams of fluid outwardly from the distribution plate into and along the discharge duct where the individual streams merge and combine into a resultant fluid stream flowing along said axis through a predetermined portion of the cross sectional area of the discharge duct.
