Rectangular to Round Adaptor
The Rectangular to Round Adaptor is engineered to provide a reliable connection between rectangular wall outlets and round ventilation ducting. It creates a smooth airflow transition while allowing different duct profiles to integrate seamlessly within a single ventilation system.
Manufactured from premium-quality PVC, the adaptor offers excellent durability and resistance to moisture, corrosion and everyday environmental conditions. Its precision-moulded construction provides a secure fit with compatible wall outlets and round ducts, helping minimise air leakage and maintain efficient ventilation performance.
The smooth internal airflow path reduces turbulence and pressure loss, promoting consistent air movement throughout the ventilation system. Its lightweight design enables quick and straightforward installation, making it suitable for extractor fan systems, kitchens, bathrooms, utility rooms, offices, commercial buildings and HVAC applications.
Designed for long-lasting reliability, the Rectangular to Round Adaptor provides a neat, professional finish while offering a durable, low-maintenance solution for new installations, refurbishment projects and replacement work.
