FHF is an innovative fire damper meticulously engineered for optimal performance in ventilation and air conditioning systems. Seamlessly integrated into supply and return air ducts, this state-of-the-art valve remains open during normal operation to guarantee smooth, uninterrupted airflow. When a fire incident occurs, and the duct smoke temperature escalates to 70ºC (158ºF), it automatically activates to close, thereby efficiently sealing off toxic smoke and preventing the spread of flames. This critical function buys precious time for safe evacuation and effective firefighting efforts.
Harnessing sophisticated sealing technology, FHF ensures negligibly low leakage rates and unparalleled airtightness. Once closed under intense heat conditions, it steadfastly blocks smoke infiltration, in strict adherence to pivotal fire codes for smoke and fire segregation, significantly bolstering the overall fire safety of any building.
Constructed from premium-grade corrosion-resistant materials, this valve exhibits a robust design with smooth and dependable functionality that effectively mitigates jamming risks. Its refined mechanical engineering promises long-term operational stability, enhanced corrosion resistance, and prolonged service life, leading to significant reductions in maintenance costs and failure likelihood.
Through rigorous testing, FHF is validated to sustain its structural integrity and indispensable fire-blocking capabilities for a minimum duration of 1.5 hours (fire resistance rating ≥1.5h) even under extreme fire conditions. This performance surpasses standard safety benchmarks, delivering exceptional fire protection suitable for a wide array of building structures.
