Ubbink Air Excellent 34C Coupling Piece for DBOX Air Distribution Box 200/800

The Ubbink Air Excellent 34C DBOX set is used to seamlessly connect a DBOX and a 34C duct within the Air Excellent air distribution system. This set ensures an airtight and mechanically stable transition between the distribution box and duct without the need for additional sealants or complex assembly. The set is supplied with two 34C Click-Seal rings, allowing you to create a secure connection immediately.

Advantages and Features

Airtight connection between DBOX and 34C: Prevents unwanted air leakage and maintains system performance.
Zeta 1.8 for supply and exhaust: Predictable system resistance for accurate sizing.
Tool-free installation: Quick setup thanks to the Click-Seal principle.
Antistatic and antimicrobial: Supports a hygienic ventilation system with reduced dust adherence.
TÜV SÜD certified: Tested for quality and safety in ventilation applications.

Performance and Practical Use

The 34C DBOX is designed for a stable airflow in both supply and exhaust. With a zeta value of 1.8, the adapter introduces a controlled pressure loss within the system. At an airflow rate of 30 m³/h, the pressure drop is approximately 7.6 Pa per connection. This allows you to accurately match the total duct run and ventilation unit to the desired airflow. The adapter is temperature resistant from -20 °C to +60 °C and complies with fire classification Euroclass E. Thanks to the compact dimensions of 81 x 81 x 48 mm, installation remains clear and manageable, even in confined spaces.

Installation and Applications

This coupling piece is used when connecting a distribution box to a 34C duct leading to valves or branches. Weighing approximately 0.13 kg, it is comfortable to install above ceilings or in technical shafts. The Click-Seal rings ensure an immediate and reliable seal without tape or sealant. Due to the precise fit within the Air Excellent system, the connection remains stable and low-maintenance throughout the installation's service life.

With this set, you achieve a technically correct and airtight connection between the DBOX and duct system, where ease of installation and predictable aerodynamic performance are paramount.
