Ubbink Air Excellent 2x 23C - 55SC Adaptor Piece

The Ubbink Air Excellent 2x 23C - 55SC adaptor piece is used to seamlessly connect a 55SC duct to two 23C ducts within the Air Excellent air distribution system. This adaptor enables the transition from a semi-circular main connection to two round 23C branches without the need for additional fittings or complex installation. The set includes two 23C Click-Seal rings, allowing you to immediately achieve an airtight and secure connection.

Advantages and Features

Transition from 55SC to 2x 23C: Provides a logical and efficient split within the ductwork.
Airtight connection: Maintains system performance through a sealed and reliable joint.
Tool-free installation: Quick assembly enabled by the click system and included Click-Seal rings.

Performance and Practical Use

The adaptor is designed for stable airflow distribution from the 55SC main duct to two 23C outlets. Its internal design minimises pressure loss and ensures control over the airflow rate directed to the connected spaces. The temperature resistance from -20 °C to +60 °C allows for installation in floors, walls, and unheated zones. With an overall length of 168 mm, a width of 148 mm, and a height of 73 mm, the unit remains compact and easy to plan within the installation process.

Installation and Applications

The 2x 23C - 55SC adaptor piece is suitable when splitting a main duct into two separate branches, for example towards valves or distribution points. Its lightweight design, approximately 0.136 kg, ensures comfortable handling, even when installed above ceilings or in technical shafts. The Euroclass E fire rating complies with current residential building requirements. The snug fit within the Air Excellent system guarantees a stable, low-maintenance connection throughout the installation’s lifespan.

This set provides a technically sound and airtight transition within the Air Excellent system, combining ease of installation with efficient airflow distribution.
