Coupler for fire-resistant duct

Couplers for fire-resistant ducts are specialized components designed to maintain the integrity of fire-rated ventilation systems during a fire event. These connectors, such as the BSKM-VD 1025 FS from OBO BETTERMANN, are engineered for wall and ceiling mounting, featuring a robust steel construction with strip-galvanized finish per DIN EN 10147. They ensure a secure seal between duct sections, preventing the spread of flames and smoke through penetrations. Key technical attributes include compatibility with duct dimensions like 100x250 mm, and materials that withstand high temperatures while preserving structural stability. These couplers are essential for passive fire protection in building services, often used in conjunction with fire dampers and smoke extraction systems.

Applications for fire-resistant duct couplers span critical sectors including commercial buildings, industrial facilities, hospitals, and high-rise structures. They are installed in ventilation and smoke management systems where fire-rated compartmentation is mandatory. Typical environments include HVAC risers, ceiling voids, and wall penetrations where ducts pass through fire-resistant barriers. These components are integral to smoke control systems, emergency stairwell pressurization, and kitchen exhaust ducts in compliance with local fire safety codes. Their design ensures that in the event of a fire, the ductwork remains sealed and operational, supporting safe evacuation and firefighting efforts.

These couplers comply with international standards such as EN 1366-1 for fire resistance tests of service installations, and EN 13501 for classification of reaction to fire. They are compatible with leading brands like OBO BETTERMANN, as well as systems from Hilti, Walraven, and others in the fire protection market. The strip-galvanized coating meets DIN EN 10147, providing corrosion resistance in demanding environments. When integrated with fire-resistant ductwork, these couplers help achieve the required fire resistance ratings (e.g., EI 60, EI 120) as per building regulations.
