Oval Duct

Designed for roof cavities with limited space, Spiroduct’s high strength oval duct tubing not only provides comparable rates of airflow, but can also be used as an architectural feature.

When space is at a premium, Oval Duct from Spiroduct Australia is the preferred choice for HVAC installations.

Used in multi-story buildings, flat roofed buildings, car parks and many other applications, all our Oval Duct is manufactured using only Spiro® machinery and techniques.
