The 500×75 Rectangular to Round 200mm adapter is a transition fitting that connects 500×75mm flat channel rectangular ducting to 200mm round ducting. This adapter provides a smooth aerodynamic transition between the largest flat channel duct profile and standard round duct connections at system endpoints.
The 500×75mm profile delivers the highest airflow capacity in the flat channel range, making this adapter essential for high-performance ventilation installations. The smooth internal transition profile minimises turbulence and static pressure loss, maintaining optimal airflow efficiency.
This adapter is commonly used to connect 500×75mm flat channel duct runs to 200mm inline fans, roof cowl outlets, wall vent terminations, and other round duct equipment. It enables the use of space-saving flat channel ducting through building cavities while connecting to round components at the endpoints.
Easy to install with push-fit connections on both ends. Seal all joints with duct tape for airtight performance. Compatible with all 500×75mm flat channel components and standard 200mm round ducting, inline fans, and ventilation accessories.
