The Starduct Insulation Fire Damper (EI120) is a high-performance fire safety component developed by STAR ASIA (NSCA), designed to prevent the spread of fire and smoke through HVAC ductwork for up to 120 minutes of fire resistance (EI120 rating).
This damper is ideal for fire compartmentalization in commercial, industrial, and public buildings. It automatically closes in the event of a fire, maintaining the integrity of fire-rated walls and ventilation systems.
