Ducting

Aluminium ducting kits from Knightsbridge link extractor fans to wall vents, with 100mm hose supplied on a 3.3m run and jubilee clips included to clamp each end. The flexible silver hose pulls out to length and trims down where a shorter route suits, keeping kitchen, bathroom and utility-room extraction tidy from the fan housing through to the outside grille.

Aluminium Flexible Ducting for Extraction and Ventilation

Aluminium flexible ducting carries warm, damp air from an extractor fan out to a wall vent, keeping kitchens, bathrooms and utility rooms clear of moisture. The hose stretches out along the run you need and trims back where a shorter route suits, so you can route it around the obstacles between the fan housing and the outside grille. With a 100mm bore, it pairs with standard extractor fans and wall outlets at the same size, and the lightweight aluminium wall holds its shape once pulled to length.

What the Kit Includes

The kit comes as a 3.3m length of 100mm aluminium hose with jubilee clips supplied to clamp each end. The clips tighten over the hose at the fan spigot and at the vent, holding the joint firm so air does not leak back into the room. Cut the hose to suit the distance between the two points, leaving enough to fix securely at both ends. Keeping the run as short and straight as the layout allows helps the fan shift air freely rather than fighting bends in the line.
