Why this ducting earns its place
The Combisteel SQUARE TO ROUND CONVERTER Ø 350 solves a common extraction challenge: matching the flat, rectangular ducting that runs above kitchen canopies to round ducting that carries air to external vents or rooftop fans. This converter makes that transition smooth and efficient, reducing turbulence and airflow loss where ductwork changes shape.
At 400 mm square base and 280 mm tall, with a 350 mm round outlet, it's sized for typical mid-scale kitchen extraction systems. The square inlet adapts to standard rectangular canopy dimensions, and the round outlet accepts 350 mm round duct—either rigid metal pipe or flexible ducting, depending on your installation. It's straightforward geometry working reliably: square air path becomes round air path with minimal resistance.
Clean, tight ducting transitions preserve extraction performance. Sloppy converter fittings create turbulence, leak air, and force fans to work harder for the same airflow result. A proper converter like this one ensures your extraction system runs at its designed efficiency. Combisteel's build quality means it stays in place and doesn't rattle, sag, or develop leaks where it connects.
