Line Set Cover Reducer Coupling

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.

Frequently Asked Questions

Q: When do I need a reducer coupling?
A: Wherever two duct sections of different profile widths meet on the same run, for example a 75 mm wall run joining a 100 mm main 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.
