ABSTRACT:
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.
