Product Overview

Compact pre-insulated plenum designed for ducted air conditioning and heat pump systems up to 4.9kW. Suitable for both supply and return air applications.

Manufactured in New Zealand from 20mm PIR pre-insulated panel, the plenum is lightweight, durable and thermally insulated, with no additional lagging required.

Our standard plenums have a compact 95mm depth, making them particularly useful where ceiling or installation space is limited.

Triangle and trapeze plenums are manufactured deeper to suit their shape and required airflow path.

Supplied with 1 spigot included.
