The Ubbink Air Excellent AE35SC Vertical Bend 90° is a Air Excellent duct accessory designed to create a 90-degree vertical change of direction when installing AE35SC ventilation ductwork. Perfect for moving duct runs up or down between levels, this fitting helps keep installations neat, compact, and efficient.

For the correct airtight installation, use 2x AE35SC seal rings and 2x AE35SC click rings to connect the AE35SC ducting to the bend (one set per connection). This produces a secure, airtight mechanical joint without the need for tape or sealant.
