Ubbink Air Excellent 45SC - 48C Transition Piece

The Ubbink Air Excellent 45SC - 48C transition piece is used to seamlessly connect a 45SC duct to a 48C duct. You apply this set when you need to switch duct types within a single ventilation system without compromising airtightness or airflow. Thanks to the included Click-Seal Ring and Seal Ring, you achieve a quick, secure, and tool-free connection.

Advantages and Features

Seamless transition between 45SC and 48C: Connect two different duct systems directly without improvisation or additional fittings.
Airtight connection: The integrated sealing rings limit air leakage and ensure stable system performance.
Low pressure loss: With a zeta value of 0.7 for both supply and extract air, the additional resistance in the duct run remains minimal, contributing to an efficient ventilation system.
Antistatic and antimicrobial: The design supports hygienic air distribution and reduces dust adhesion inside the duct.

Performance in Practice

A well-designed transition prevents unnecessary turbulence in the duct. The controlled change between the two diameters maintains airflow, reducing the need for the fan to compensate for pressure loss. This results in lower energy consumption and quieter system operation.

The transition piece is suitable for temperatures from -20 °C to 60 °C and complies with fire classification Euroclass E. With a length of 282 mm, width of 176 mm, and height of 103 mm, you can integrate it precisely into walls, floors, or technical rooms. Weighing approximately 0.22 kg, it offers a stable yet easily manageable installation.

Installation and Maintenance

You install the transition piece directly between the 45SC and 48C duct and click the connection in place. Since no tape or sealant is needed, you work faster and more consistently on site. The fixed seal remains reliable over the long term and requires no additional maintenance.

This set enables you to achieve a technically correct and airtight transition within your ventilation system, focusing on ease of installation and system efficiency.
