Why this ducting earns its place
The 200 mm round elbow is the go-to size for most small to medium commercial kitchens. It's large enough to move serious heat and steam from a cooking line without undersizing, but compact enough to route through tight plant rooms and suspended ceilings.
Round ducting at 200 mm diameter gives you the efficiency of smooth pipe — less friction loss than square, quieter operation, easier to clean. This is the size you'll find specified most often when a kitchen needs extraction that just works without fuss. Restaurants, takeaways, pubs, and small hotel kitchens all gravitate toward 200 mm round as the sweet spot.
The 90° elbow lets you make proper corners. Route it from your hood or cooking zone to a main trunk, or use it to snake ducting around an awkward ceiling void. The smooth curve of the bend keeps air moving efficiently — no turbulence, no pressure spikes that leave extraction gasping.
