Why this ducting earns its place
Round ducting is the premium choice for extraction — lower friction loss, smoother airflow, quieter operation. This 90° elbow in 250 mm diameter is the standard turning piece for larger kitchens and high-capacity extraction systems.
Round pipe feels modern and flows air efficiently. The 250 mm size sits in the middle range — large enough to handle serious heat and steam loads without choking, but manageable to route through most ceiling rigs and plant rooms. Where square ducting can create turbulence at corners, round pipe keeps the air moving with minimal resistance.
Use this wherever your round extraction run needs to turn. Whether you're routing the main trunk from a bank of cookers to the wall, or creating a feeder from a local hood to the main line, the round 90° bend is the way that works. It's become the standard for new kitchens and bigger refits because the airflow just works better.
