DFDAF-330 : Multi-Blade Fire Damper
Model DFDAF-330 is a multi-blade, airfoil-style dynamic-rated fire damper designed for installation in walls, floors, and partitions with fire-resistance ratings of three hours or greater. Qualified for HVAC systems that remain operational during a fire emergency, it provides reliable closure under airflow conditions while supporting code-compliant life safety performance. The airfoil blade design enhances aerodynamic efficiency, reducing pressure drop and contributing to improved system performance during normal operation.
