250mm to 180mm Duct Adapter — Reducer with Hose Clamp Grooves | 250mm to 180mm European Range Hood Commercial Extraction Bridge

250mm commercial extraction trunk stepping down to 180mm — the standard outlet size on European range hoods and domestic kitchen ventilation appliances. This adapter connects large-bore commercial infrastructure to European appliance standards at the top of the catalog scale. 250mm sits at the apex of large-bore commercial and industrial extraction. 180mm is the outlet standard on European range hoods and kitchen ventilation units from Bosch, Siemens, Miele, Neff, and compatible brands — the domestic appliance scale that operates just below the commercial tier. These two sizes meet in high-specification commercial kitchens where multiple 180mm appliance outlets feed into a 250mm commercial main, in premium residential builds where commercial-grade 250mm extraction serves European domestic appliances, and in any installation where the top end of commercial extraction infrastructure needs to interface with the European appliance outlet standard. The near-flat saucer profile of the 250→180mm is among the most dramatic in the catalog — 70mm differential at 250mm base diameter produces a wide, dramatically flared reducer that commands presence in any large-bore installation. Four millimetre walls from the 250mm rim to the 180mm outlet, dual hose clamp grooves at both ends, smooth internal bore throughout the extreme flare. ✅ What Makes This Different 4mm uniform wall thickness — maintained across the near-flat saucer from the 250mm rim to the 180mm outlet; structural integrity…
