Why this ducting earns its place
Ducting converters are the essential bridges in extraction systems. Where a canopy or branch duct differs in diameter from your main riser or outlet, you need a converter to step cleanly between them. This 200–350 mm converter is a compact, lightweight solution: it weighs just 2 kg, making it simple to handle and position during fit-out.
The converter sits inline where the diameter changes. It's sized to mate with both your incoming and outgoing ducts—a direct transition with no guesswork. Install it between a 200 mm branch (from a smaller unit or section) and a 350 mm riser, or use it reversed if your layout calls for the step in the opposite direction. In extraction systems, getting the diameter right at every joint keeps airflow smooth and prevents velocity loss or turbulence.
Because extraction systems must match the canopy and appliances they serve, converters come in several size ranges. Pick the one that bridges YOUR two duct sizes. The physical fit—duct clamp or socket connection—depends on your ducting type (spiral, rectangular), so confirm your branch and riser diameters before ordering.
