This flat oval semi-rigid radial duct is designed for residential heat recovery and mechanical ventilation systems where long, continuous duct runs are required. The 52mm low-profile format allows installation in confined voids while supporting efficient airflow over extended distances.
Supplied as a 50m continuous coil, the duct is well suited to larger properties and multi-room layouts. Fewer joints are required compared to shorter lengths, helping to reduce air leakage and support consistent system performance.
An internal anti-bacterial and anti-static lining helps maintain duct hygiene and supports long-term indoor air quality, making it suitable for professional ventilation installations in both new build and retrofit projects.
The semi-rigid construction allows the duct to curve smoothly around structural elements such as beams, pipework and cabling. This flexibility reduces the need for additional bends and fittings, simplifying installation in complex layouts.
The duct can be cut easily with a sharp blade, allowing accurate on-site adjustment and efficient installation across longer runs.
The 50m coil length supports uninterrupted duct routes, helping to maintain airtightness and reduce pressure losses within heat recovery or extract ventilation systems. This contributes to stable airflow rates and efficient system operation.
The slim 52mm profile enables routing through shallow floor zones, ceiling voids and wall cavities, making it suitable for retrofit projects where space is limited. Reduced installation time compared to rigid ducting helps lower labour costs and minimise disruption.
A smooth internal surface limits airflow resistance, while the rigid form prevents sagging. Together, these characteristics help reduce condensation risk, support moisture control and contribute to mould prevention within the building.
This duct is suitable for use in residential heat recovery ventilation and mechanical extract ventilation systems. The 50m length is particularly effective for larger homes, apartments and multi-room dwellings requiring longer duct routes.
Typical installation locations include ceiling voids, service risers, floor zones and partition walls in new build housing, refurbishment projects and social housing upgrades.
All connections should be sealed to maintain airtightness and system efficiency. In unheated areas, insulation is recommended to prevent thermal losses and condensation.
The duct is compatible with flat oval ventilation components and can be integrated into wider ventilation layouts using appropriate adaptors. Correct installation supports reliable long-term performance and compliance with Building Regulations.
