The Ubbink Air Excellent AE34C – AE35SC 90° Adaptor is a dedicated ducting accessory designed to connect an AE34C duct to an AE35SC duct while introducing a controlled 90-degree change in direction. It provides a neat, space-efficient solution for transitioning between duct sizes within the Air Excellent ventilation system.

Engineered for seamless compatibility with Air Excellent modular manifolds and ductwork, this adaptor uses airtight mechanical connections to ensure reliable system performance. Its efficient radial design helps minimise pressure loss, supporting lower fan energy consumption and quieter operation — exactly what’s expected from a properly balanced ventilation system.

When installed with the correct seal and click rings, the adaptor delivers a secure, tape-free connection that’s quick to fit and built to last.
