The Ubbink Air Excellent 2 × AE34C 125mm 180° Valve Adaptor is a versatile ducting accessory designed to connect up to two AE34C semi-rigid ducts to a single 125mm supply or extract valve. Its straight-through 180-degree configuration makes it ideal for balanced, symmetrical duct layouts where a neat, professional finish is required.

This adaptor can be cut to length on site, allowing installers to fine-tune the fit to suit ceiling depths and valve positions. When used with AE34C click-seal rings, it delivers a secure, fully airtight mechanical connection — no tape, no sealant, and no guesswork.

Designed as part of the Air Excellent radial ducting system, the adaptor helps minimise pressure losses, reduce fan energy consumption, and keep system noise to a minimum. Supplied with a mounting strip for fast, secure fixing, it keeps installation simple and reliable from first fix to final commissioning.
