The 310×70 Rectangular to Round 200mm adapter is a transition fitting designed to connect 310×70mm flat channel rectangular ducting to standard 200mm round ducting. This adapter is essential at transition points where the duct system changes from flat channel to round, such as at inline fan connections, roof cowl outlets, or wall vent terminations.
The aerodynamic internal profile ensures smooth airflow transition between the rectangular and circular duct shapes, minimising turbulence and static pressure loss. This maintains extraction efficiency and prevents noise generation at the transition point.
Commonly used in kitchen rangehood ducting, bathroom exhaust, and whole-home ventilation systems, this adapter allows the benefits of low-profile 310×70mm flat channel ducting through wall cavities and ceiling spaces while connecting to 200mm round ducting components at the system endpoints.
Easy to install with push-fit connections to both flat channel and round ducting. Seal all joints with duct tape for airtight performance. Compatible with all 310×70mm flat channel components and standard 200mm round ducting, inline fans, and accessories.
