Spiral Duct Collar

Spiral duct collars SDC are used to create branch connections in round duct systems. They allow efficient airflow distribution while ensuring a secure and precise fit within the main duct.

These components are essential for diverting airflow from the main duct into multiple branches, enabling balanced air supply to different areas of the system. Their design helps minimize turbulence and pressure losses, maintaining optimal ventilation performance.

SDC collars are typically manufactured from galvanized sheet metal or stainless steel, providing corrosion resistance and long service life. They are available in various diameters to match standard spiral duct sizes and project requirements.

Installation is simple and involves cutting an opening in the main duct and fixing the collar using screws, rivets, or other standard fastening methods. This ensures a stable and airtight connection, reducing air leakage and improving system efficiency.

In practice, SDC duct collars are an important component for building flexible and efficient ventilation systems, allowing easy expansion and adaptation of duct networks.
