Ubbink Air Excellent 23C Coupler

The Ubbink Air Excellent 23C coupler is used to seamlessly connect two Air Excellent 23C ventilation ducts. This set ensures an airtight and mechanically stable connection, allowing you to easily extend the ventilation duct without additional fittings or complex assembly. Thanks to the well-designed click system, you can quickly create a reliable connection that is immediately ready for further installation.

Advantages and Features

Airtight Connection: The included 23C Click Seal rings provide a dependable seal, preventing air leakage and preserving the calculated performance of the ventilation system.
Low Pressure Loss: With a zeta value of 0 for both supply and exhaust air, air resistance remains minimal, limiting the fan’s energy consumption.
Tool-Free Installation: The click system enables quick assembly without the need for extra tools, saving time on site.
Antistatic and Antimicrobial: The material contributes to a hygienic and safe ventilation system, suitable for both residential and commercial applications.
TÜV SÜD Certified: Tested for quality and safety, ensuring a durable and reliable connection.

Performance and Practical Use

The 23C coupler is engineered for optimal system performance within the Air Excellent ducting system. Due to minimal pressure loss, the efficiency of the ventilation unit is maintained even over longer duct runs. This results in stable air distribution and efficient operation of the overall system. Its temperature resistance from -20 °C to +60 °C makes the coupler suitable for a variety of installation environments, from unheated spaces to technical shafts. With a length of 133 mm and a width and height of 73 mm, the coupler remains compact and easy to integrate into floors, walls, and ceilings.

Installation and Applications

The coupler is installed directly between two 23C ducts. Weighing approximately 0.068 kg, it allows for comfortable and swift installation, even in hard-to-reach areas. The integrated Click Seal rings immediately ensure a proper seal without additional sealing materials. Thanks to the Euroclass E fire classification, the coupler complies with the applicable requirements for ventilation components in residential construction projects. Maintenance is minimal, as the connection remains secure and stable within the duct run.

With this 23C set, you achieve a reliable, airtight, and energy-efficient connection within the Air Excellent ventilation system. You combine quick installation with stable system performance, ensuring your installation is technically sound and remains functional for the long term.
