Air Extract Valves

Metal air extract valves for bathrooms, WCs, kitchens and utility rooms, made from galvanised steel with a white powder-coated finish for a durable, easy-clean surface. Fitted in a ceiling or wall at the end of a rigid or flexible duct run, they draw stale, moist air into the ductwork while keeping a tidy, unobtrusive appearance — a healthier environment for homes, workplaces and public washrooms alike.

Five sizes are stocked to suit standard round ducting: 100mm, 125mm, 150mm, 160mm and 200mm, so there is a valve to match the most common extract duct diameters. Order by 3pm for next-day delivery, with free UK mainland delivery on orders over £400 ex VAT.

Where the ventilation design requires fire protection, choose our fire-rated air extract valves with intumescent protection. For the supply side of the system, see air supply valves, and make installation easier with the Terlok Ring Leader fixing ring, available in matching sizes.
