Ubbink Air Excellent 34C 90° Elbow Connector

The Ubbink Air Excellent 34C 90° elbow connector is used to join two 34C ducts at a right angle within the Air Excellent air distribution system. This elbow enables a controlled 90-degree directional change without compromising airtightness or system performance. The set comes with two 34C Click-Seal rings, allowing you to create a secure, tool-free connection immediately.

Advantages and Features

Airtight 90° connection: Maintains calculated airflow performance throughout the duct run.
Zeta 1 for supply and exhaust: Ensures controlled pressure loss with predictable system resistance.
Tool-free installation: Quick assembly thanks to the click system and integrated sealing rings.
Antistatic and antimicrobial: Supports a hygienic ventilation system with reduced dust adhesion.
TÜV SÜD certified: Tested for quality and safety in ventilation applications.

Performance and Practical Use

The 34C 90° elbow has an outer diameter of 75 mm and is designed for stable airflow in both supply and exhaust applications. With a zeta value of 1, the elbow introduces manageable resistance into the system. At an airflow rate of 30 m³/h, the pressure loss is approximately 4.2 Pa per connection. This allows accurate dimensioning of the duct run, ensuring the ventilation unit operates within its designed capacity. The elbow is temperature resistant from -20 °C to +60 °C and complies with fire classification Euroclass E. Its dimensions of 144 x 144 x 86 mm keep the installation compact and organised.

Installation and Applications

The 34C 90° elbow is applied when ducts must be routed around structural elements or when the available space requires a change in direction. Its light weight of approximately 0.092 kg makes installation comfortable, even when mounted above ceilings or inside technical shafts. The precise fit within the 34C system ensures a stable, low-maintenance connection throughout the entire service life of the installation.

Using this 34C 90° elbow, you can direct airflow through the ventilation system in a controlled manner, combining ease of installation with reliable and predictable performance.
