Ubbink Air Excellent 48C Coupling Piece

The Air Excellent 48C coupling piece is used to seamlessly connect two 48C ducts. Use this set when you want to create a straight connection within the duct system without additional fittings or sealants. Thanks to the two included 48C Click-Seal rings, you achieve a quick, airtight, and tool-free installation.

Benefits and Features

• Seamless duct connection: Connect two 48C ducts directly and securely to ensure a stable duct run.
• Airtight without added resistance: With a zeta value of 0 for both supply and exhaust, no additional pressure loss is introduced into the system.
• Fast Click-Seal installation: Install the connection without tools, tape, or sealant.
• Antistatic and antimicrobial: The design supports hygienic air distribution and reduces dust adhesion.

Performance in Practice

A straight coupling with minimal resistance directly contributes to an efficient ventilation system. Because this connection set does not generate extra pressure loss, the designed airflow rate is maintained, and the fan does not need to work harder than necessary. This results in energy-efficient and quiet operation.

The set is suitable for temperatures ranging from -20 °C to 60 °C and complies with fire class Euroclass E. With a length of 141 mm and a width and height of 103 mm, the coupling easily integrates into floor, wall, or ceiling installations. Weighing approximately 0.098 kg, it ensures stable and comfortable handling during installation.

Installation and Maintenance

Position the coupling piece between two 48C ducts and snap the connection into place using the integrated Click-Seal rings. The mechanical seal remains durable and reliable throughout the ventilation system’s lifespan, requiring no additional maintenance or periodic inspection of sealing materials.

This set enables a simple, airtight, and technically sound duct connection within the Air Excellent duct system.
