BIC Rectangular to Round Transition – Versatile Connection for Mixed-Shape Ventilation Ducting

The BIC rectangular to round transition is a specially designed component that enables a secure and airtight connection between rectangular and round ventilation ducts. It allows the seamless integration of different duct shapes into a unified system while maintaining consistent airflow and high energy efficiency.

• The rectangular side comes with standard flanges compatible with DW 20, DW 30, DW 40, or Z profiles, ensuring a stable and professional connection to ductwork or structural components.

• The round side is equipped with integrated rubber gaskets, providing a tight and vibration-resistant seal when connected to circular ducts or fittings.

• Available in both centrical and eccentric versions to accommodate axial or offset transitions depending on spatial requirements.

• The length of the transition can be customized, including optional extended versions upon request to meet specific installation needs.

• Manufactured from high-quality galvanized DX51D sheet steel, with a 275 g/m² zinc coating, ensuring durability, mechanical strength, and corrosion resistance in demanding environments.

• Enables smooth airflow transition between rectangular and round duct sections

• Ensures airtight performance, reducing energy losses

• Quick and easy installation using standard mounting systems

• Customizable design to fit various residential, commercial, or industrial applications

This transition is widely used in ventilation systems where a connection is required between rectangular ducts and round ducts, such as near ventilation units, fans, branches, or system conversions.
