The Sunco Duct Twin-Spigot Return Air Plenum is a lightweight, insulated return-air box designed to connect a return-air grille to two flexible duct runs.
Manufactured from 21 mm foil-faced PIR ductboard, the plenum combines the air path and insulation into one compact assembly. The twin-spigot configuration helps divide the return airflow across two ducts, providing additional airflow capacity while helping reduce air velocity and system noise.
