The reducer coupling steps between two different profile widths, for example where a 75 mm run from the indoor unit widens to 100 mm for a bundle carrying extra cables. It keeps the transition inside the trunking instead of leaving an open gap at the change of size. This fitting is supplied in black, moulded from the same colour-through PVC as the black kit, so joints and corners stay invisible on the wall.

Black suits the dark design language of modern builds: anthracite window frames, dark cladding, charcoal render and minimalist commercial frontages. On these walls a light-coloured run would stand out badly, while the coupling reads as part of the architecture instead of pipework. As with every colour in the range, the pigment is moulded all the way through the PVC, so the finish will not peel or flake. Combined with the matching kit, it gives a continuous matte line from the indoor unit to the outdoor condenser.
Q: When do I need a reducer coupling?
A: Wherever two duct sections of different profile widths meet on the same run.
Q: Which size combinations are available?
A: Reducer combinations are produced to order. Confirm the exact pair you need with our sales team before the order is placed.
Q: Does the standard cover still fit over the reducer?
A: Yes. The reducer is closed with the matching covers of each width, so the run stays enclosed.
