Plenums

HVAC plenums are essential for distributing air efficiently in ducted air conditioning and heat pump systems. Selecting the right plenum ensures balanced airflow, quieter operation, and overall system performance.

Our range is designed to suit different indoor unit capacities, making it easy to choose the right option for your installation:

  • Mini Plenums — suited to indoor units up to 4.9kW
  • Standard Plenums — suited to indoor units 5.0kW and above
  • Large Body Plenums — for higher airflow requirements and specialised applications

All plenums are available in multiple configurations, including base units, pre-fitted spigots, and dampered outlets, helping streamline installation while maintaining control over airflow.

Manufactured onsite in our factory, using quality materials, our plenums are built for durability, consistency, and fast installation across a wide range of residential and commercial projects.

Need something specific? We also offer custom plenum fabrication to suit unique layouts and system requirements.
