Sunco Duct Twin-Spigot Supply Air Plenum – 21mm PIR
The Sunco Duct Twin-Spigot Supply Air Plenum is a lightweight, insulated air-distribution box designed to divide supply airflow between two flexible duct runs.
Manufactured from 21 mm foil-faced PIR ductboard, the plenum combines the air path and insulation into one compact assembly. Its tapered body promotes smoother airflow toward both outlets while reducing the weight and installation time associated with traditional sheet-metal plenums.
