DUX – dual flow pressure relief damper for chemical gas

DUX Dual Flow Pressure Relief Damper for Chemical Gas Fire Suppression

 

The DUX Dual Flow Pressure Relief Damper is a high-performance overflow unit specifically designed for chemical (halocarbon) gas fire suppression systems. As the world’s first two-way pressure relief vent for halocarbon agents such as FM-200® and Novec™ 1230, DUX effectively manages both positive and negative pressure during system discharge, protecting room integrity and critical infrastructure.

Its innovative dual-pivot blade design allows adjacent blades to interlock, delivering exceptional pressure relief performance with minimal leakage. This ensures fast, controlled pressure balancing while maintaining superior fire containment, making DUX ideal for data centers, control rooms, laboratories and mission-critical enclosures.

Manufactured from Zintec steel and powder-coated to RAL 9003, the DUX offers durability, reliability and long-term performance. Available in multiple standard sizes and adaptable for wall or ceiling-mounted installations, it provides a proven and engineered solution for modern chemical gas fire suppression applications.
