Ubbink Air Excellent 48C - 55SC reducer

Ubbink Air Excellent 48C - 55SC Adaptor

The Ubbink Air Excellent 48C - 55SC adaptor is used to connect a 48C duct to a 55SC duct. This set is ideal when you want to combine two different duct types within one ventilation system without compromising air tightness or ease of installation. Thanks to the supplied 48C Click-Seal Ring, you can work quickly and without additional sealing materials.

Advantages and Features

• Seamless transition between 48C and 55SC: Connect two duct types directly while maintaining a stable and organised duct run.
• Airtight connection: The sealing rings minimise air leakage and support reliable system performance.
• Antistatic and antimicrobial: This design contributes to hygienic air distribution and reduces dust adhesion inside the duct.

Performance in Practice

A well-designed adaptor prevents unnecessary turbulence and extra load on the fan. The adaptor has a low pressure loss to reduce the energy consumption of the fan and is suitable for temperatures from -20 °C to 60 °C. Additionally, it meets fire classification Euroclass E. With a length of 242 mm, width of 148 mm and height of 102 mm, this component can be neatly integrated into walls, floors or ceilings. The weight of approximately 0.146 kg ensures stable and convenient installation.

Installation and Maintenance

The adaptor is placed directly between the 48C and 55SC ducts and snapped into place with the integrated rings. Since no sealant or tape is required, installation on site is faster and more consistent. The mechanical seal remains durable and low-maintenance throughout the lifespan of the ventilation system.

This adaptor enables a compact, airtight and technically sound transition between 48C and 55SC within the Air Excellent duct system.
