Ubbink Air Excellent 34C Coupling Piece

The Ubbink Air Excellent 34C coupling piece is used to seamlessly connect two 34C ducts within the Air Excellent air distribution system. This set allows you to extend the duct run quickly and in a controlled manner, without the need for additional sealing materials or complex assembly. The set includes two 34C Click-Seal rings, enabling you to achieve an airtight and stable connection immediately.

Advantages and Features

Airtight connection: Ensures a closed duct system and maintains the calculated airflow performance.
Zeta 0 for supply and exhaust: No additional pressure loss through the coupling, preserving the efficiency of the ventilation unit.
Tool-free installation: Fast assembly thanks to the Click-Seal principle.
Antistatic and antimicrobial: Supports a hygienic ventilation system with reduced dust accumulation.
TÜV SÜD certified: Tested for quality and safety in ventilation applications.

Performance and Practical Use

The 34C coupling piece is designed to provide stable airflow for both supply and exhaust. With a zeta value of 0, the coupling introduces no additional resistance in the duct run. This means that the airflow and energy consumption of the fan correspond to the calculated system values. The connection is temperature resistant from -20 °C to +60 °C and complies with fire class Euroclass E. With a length of 133 mm and a width and height of 85 mm, the compact design is easy to integrate into floors, walls, and ceilings.

Installation and Applications

You install the coupling piece directly between two 34C ducts. Thanks to the lightweight design of approximately 0.075 kg, installation is comfortable, even when mounting above ceilings or inside technical shafts. The Click-Seal rings immediately ensure proper sealing without the need for tape or sealant. The tight fit within the Air Excellent system ensures a stable, low-maintenance connection throughout the entire service life of the installation.

With the Air Excellent 34C set, you achieve a reliable and energy-efficient extension of the duct run, where ease of installation and consistent system performance are paramount.
