Regulating fire dampers are critical safety control devices in ventilation and smoke exhaust systems, combining airflow regulation with fire protection functions. By manually or electrically adjusting blade angles, they precisely control air volume. During fire incidents, thermal actuators trigger immediate closure to block smoke spread, achieving fire resistance ratings of 30-120 minutes.
Compatible with air and smoke media, these dampers install where ducts penetrate fire compartments. They are widely deployed in buildings, shopping malls, hospitals, and other facilities to ensure fire safety and ventilation system stability.
