Why this ducting earns its place
Extraction systems rely on smooth, uninterrupted airflow to move heat and steam out of the kitchen. Where duct sizes change — whether stepping down from a larger hood riser or connecting to a smaller branch run — a proper converter ensures the transition happens cleanly, without turbulence or pressure loss. This Combisteel converter handles the 200–300 mm transition, making it essential for kitchens where ducting runs need to flex between different diameters without compromising ventilation performance.
The converter is compact and lightweight (2 kg), designed to bolt into place within extraction systems you've already commissioned. Combisteel's stainless construction holds up to the grease, heat, and constant use of a working kitchen. The geometry is engineered to guide airflow smoothly through the reduction, so you don't lose suction power at the point of transition — that matters when you're trying to clear a busy service without lag.
When you're fitting out a kitchen or retrofitting an extraction system, getting the duct sizing right is half the battle. A converter bridges those mismatches and keeps the whole system breathing.
