The ecoDUCT™ Rectangular to Round Adaptor (300mm x 70mm to Ø150mm) creates a smooth transition between low-profile rectangular ducting and 150mm round duct systems. As a result, it helps maintain efficient airflow while making installation easier in ceiling spaces where height is limited. Therefore, it is an ideal solution for both residential and commercial ventilation systems.
ecoDUCT™ is manufactured in Australia from high-quality PVC and is the only Australian-made low-profile PVC ductwork system that complies with relevant Australian Standards and National Construction Code requirements. In addition, the lightweight and corrosion-resistant design offers a practical alternative to traditional sheet metal ducting. This makes it well suited to bathroom exhaust fans, laundry ventilation systems and rangehood installations.
