Ubbink Air Excellent 48C - 55SC bend 90° reducer - vertical

Ubbink Air Excellent 48C - 55SC 90° Elbow Reducer - Vertical

The Ubbink Air Excellent 48C - 55SC 90° elbow reducer - vertical is used to seamlessly connect a 48C duct to a 55SC duct when making a 90° bend in a vertical direction. This fitting is ideal for situations requiring a height transition within a compact ventilation route, such as in shafts, walls, or plant rooms. Thanks to the integrated sealing rings, you achieve a quick, airtight, and mechanically stable connection without the need for additional sealants.

Advantages and Features

• Seamless transition between 48C and 55SC: Connect two different duct types directly while maintaining proper airflow within the system.
• Vertical 90° bend in one solution: Easily create a compact directional change without combining separate accessories.
• Airtight connection with low resistance: The included Click-Seal Ring and Seal Ring minimize air leakage and pressure loss, reducing the fan’s energy consumption.
• Tool-free installation: The click system accelerates installation and reduces the risk of assembly errors on site.

Performance and Practical Application

A well-designed bend significantly influences the overall pressure loss in a ventilation system. The airtight connection and thoughtful design ensure a stable and predictable airflow. This results in quieter operation of the installation and a more consistent airflow per room.

This reducer is suitable for temperatures ranging from -20 °C to 60 °C and complies with fire classification Euroclass E. With dimensions of 271 mm length, 148 mm width and 137 mm height, it integrates precisely into vertical configurations where space and sizing are critical. Its lightweight design of approximately 0.146 kg contributes to comfortable handling during installation.

Installation and Maintenance

Install the reducer directly between the 48C and 55SC ducts and secure the connection using the supplied sealing rings. Because no sealant or tape is required, you benefit from faster and cleaner work. The fixed mechanical seal remains reliable over time without the risk of drying out or detachment of sealing materials.

This elbow allows you to create a compact, airtight, and technically sound directional change in your ventilation system, combining ease of installation with optimal system performance.
