The ecoDUCT™ Rectangular to Round Adaptor (300mm x 70mm to Ø200mm) is designed to provide a smooth and efficient transition between low-profile rectangular ducting and 200mm round duct systems. Engineered for residential and commercial ventilation applications, this fitting helps maintain airflow performance while simplifying duct installation in ceiling spaces with limited clearance.
Manufactured in Australia from high-quality PVC, ecoDUCT™ is the only Australian-made low-profile PVC ductwork system that fully complies with relevant Australian Standards and National Construction Code requirements. Its lightweight, corrosion-resistant design offers a practical alternative to traditional sheet metal ducting for bathroom exhaust fans, laundry ventilation systems and rangehood installations.
