Why this ducting earns its place
When your hood is standard 400 × 400 mm but your ductwork run is 200 mm round — which happens in smaller kitchens, compact fit-outs, or where space is tight — this converter bridges the gap smoothly.
The internal taper keeps air moving instead of creating turbulence and backpressure. It's a bigger step down than a 300 mm converter, so it's best for hoods where the airflow is naturally lower, or where the ductwork runs short and straight. If your hood's trying to push a lot of air, it'll feel the squeeze.
At 400 × 400 × 280 mm, it's the same size as the 300 mm version but routes to a narrower round duct. Band it to the hood, band it to your 200 mm ductwork, and you're done.
