FHF is a fire damper specifically designed for ventilation and air conditioning systems, installed in supply and return air ducts. The valve remains open during normal operation to ensure unimpeded airflow. When a fire raises the duct smoke temperature to 70ºC (158ºF), it automatically shuts down, effectively blocking toxic smoke and flame spread-buying critical time for evacuation and firefighting.
Featuring advanced sealing technology, FHF delivers extremely low leakage rates and superior airtightness. When closed under high temperatures, it robustly prevents smoke penetration, strictly meeting core fire codes for smoke and fire compartmentation, significantly enhancing building fire safety.
Crafted from high-strength corrosion-resistant materials, the valve boasts a rugged structure with smooth, reliable operation that eliminates jamming risks. Its optimized mechanical engineering ensures long-term stability, strong corrosion resistance, and extended service life, substantially reducing maintenance costs and failure rates.
Rigorously tested, FHF maintains structural integrity and fire-blocking functionality for at least 1.5 hours (fire resistance rating ≥1.5h) under extreme heat. This exceeds basic safety standards, providing superior fire protection for diverse building types.
