The Ubbink Air Excellent AE34C 90° Bend is a purpose-designed duct accessory used to change direction within AE34C semi-rigid duct runs. It allows a clean, controlled 90-degree turn while maintaining the airflow efficiency and airtight performance expected from the Air Excellent system.

Designed for seamless integration with Air Excellent modular manifolds and ducting, this bend uses secure mechanical connections to deliver a tidy, tape-free installation. When installed using 2 × AE34C seal rings and 2 × AE34C click rings, it ensures a fully airtight joint that helps keep pressure loss to a minimum, reduces fan energy use, and limits sound production.

Ideal for compact layouts and complex routing, the AE34C 90° bend makes directional changes straightforward without compromising system performance — a proper solution, done the right way.
