Ubbink Air Excellent AE55SC Horizontal Bend 90° is a duct accessory designed to create a smooth 90-degree horizontal change of direction within AE55SC semi-rigid ventilation duct systems. It forms part of the trusted Air Excellent range, developed for fast installation, airtight performance, and long-term system efficiency.

Manufactured to maintain consistent airflow, the radial bend design keeps pressure loss to a minimum, helping reduce fan energy use and operating noise. The AE55SC bend connects securely using two AE55SC seal & click rings (required, not included), creating a robust mechanical joint without the need for tape or additional sealants.

Compatible with modular manifolds and suitable for use across all six Air Excellent duct types, this component is ideal for residential and light commercial MVHR and ventilation installations where space-saving, airtight routing is essential.
