Ubbink Air Excellent 2x 34C - 45SC 90° Bend Adapter

The Air Excellent 2x 34C - 45SC 90° adapter is used to connect one 45SC duct to two 34C ducts in a 90° configuration. This set is ideal when you want to branch out from a larger main duct into two smaller outlets with a fixed directional change. Thanks to the included 34C Click-Seal rings and 45SC Seal Ring, you achieve a quick, airtight, and tool-free connection.

Advantages and Features

Transition from 45SC to 2x 34C: Creates a compact and clear split from one duct to two branches.
Integrated 90° bend: The fixed angle ensures controlled directional change within the duct run.
Airtight connection: The supplied sealing rings minimise air leakage and support stable system performance.
Quick installation without tools: The Click-Seal mechanism speeds up fitting and reduces the risk of installation errors.

Performance in Practice

A well-designed split prevents unnecessary turbulence and additional strain on the fan. With a zeta value of 1.96 for both supply and exhaust air, pressure loss remains predictable within the ventilation system design. This ensures control over airflow in both branches.

The adapter is suitable for temperatures ranging from -20°C to 60°C and meets Euroclass E fire rating. With dimensions of 208 mm length, 200 mm width, and 110 mm height, it integrates seamlessly into floors, walls, or ceilings. Weighing approximately 0.23 kg, it guarantees a stable and robust installation.

Installation and Maintenance

Install the adapter directly between the 45SC duct and the two 34C ducts, securing the connection with the integrated rings. Since no sealant or tape is required, installation is faster and more consistent on site. The mechanical seal remains durable and low-maintenance throughout the lifespan of the ventilation system.

This 90° set provides a compact, airtight, and technically sound duct split within the Air Excellent duct system.
