Manufacturing

Designed and manufactured in New Zealand by Airflow Engineering for ducted HVAC installations.

The Airflow Configurable Plenum Range combines standardised plenum bodies with flexible outlet configurations, allowing installers to select the number, size and order of spigots required without the need for a fully custom plenum.

For installations that fall outside the standard range, custom plenum fabrication is also available.
