Ubbink Air Excellent AE55SC Vertical Bend 90° is a duct accessory used to create a smooth 90-degree vertical change of direction within AE55SC semi-rigid ventilation duct systems. Part of the Air Excellent range, it delivers dependable airtight performance with fast, no-nonsense installation.

Its radial internal design maintains efficient airflow while keeping system pressure loss to a minimum, helping to reduce fan energy consumption and operating noise. Connections are made using two AE55SC seal & click rings (required, not included), forming a secure mechanical joint without tapes or sealants.

Compatible with modular manifolds and suitable for use with all six Air Excellent duct types, this vertical bend is ideal for MVHR and ventilation installations where ducting needs to transition cleanly between levels while maintaining airtight integrity.
