The 310×70 Rectangular to Round 150mm adapter is a transition fitting that connects 310×70mm flat channel rectangular ducting to standard 150mm round ducting. This adapter provides a crucial connection point where flat channel ducting needs to transition to round duct, typically at inline fan connections, roof cowl outlets, or wall vent terminations.
The smooth internal profile ensures efficient airflow transition between the rectangular and circular shapes, minimising turbulence and maintaining extraction performance. The gradual transition reduces noise and static pressure loss at the connection point.
This adapter is widely used in kitchen rangehood installations, bathroom exhaust systems, and general ventilation applications where 310×70mm flat channel ducting runs through wall cavities and ceiling spaces need to connect to 150mm round ducting components.
Installation is simple with push-fit connections on both ends. Seal all joints with duct tape for airtight ventilation performance. Compatible with all 310×70mm flat channel components and standard 150mm round ducting accessories including inline fans, backdraft dampers, and roof cowls.
