The Ubbink Air Excellent 125mm Valve Adaptor Extension is a practical accessory designed to extend an Air Excellent valve adaptor by 200 mm, giving installers extra flexibility when aligning valves with ceilings, walls, or service voids.

With a 125 mm diameter, this extension is perfectly suited for the quick and secure fitting of Ubbink Haelix high-performance extract and supply valves. The extension is easy to cut to length on site, allowing it to adapt seamlessly to varying layouts and installation constraints — a small detail that makes a big difference when things don’t quite line up first time.

Fully compatible with the Air Excellent system, the extension uses airtight mechanical connections to maintain system efficiency. This helps reduce fan energy use and keeps noise levels down, delivering the kind of quiet, balanced ventilation traditional installers appreciate.
