90° Elbow Rectangular to Round
The 90° Elbow Rectangular to Round is engineered to provide a seamless transition between flat rectangular ducting and round ducting while changing the airflow direction through a precise 90-degree angle. It is an essential fitting for ventilation systems where both duct profiles are used within the same installation.
Manufactured from premium-quality PVC, the fitting offers excellent durability and resistance to moisture, corrosion and everyday environmental conditions. Its precision-moulded construction ensures a secure fit with compatible ducting components, helping reduce air leakage while maintaining consistent airflow.
The smooth internal airflow path minimises turbulence and pressure loss, improving the overall efficiency of extractor fans, HVAC systems and general ventilation installations. Its lightweight design enables quick and simple installation, making it suitable for kitchens, bathrooms, utility rooms, offices, retail premises and commercial buildings.
Designed for compatibility with flat rectangular and round ducting systems, the 90° Elbow Rectangular to Round provides a professional finish while delivering reliable, low-maintenance performance for new installations, refurbishment projects and replacement work.
