Motorized Fire Damper for Air Condition in Cleanroom AHU System

Product description:

Fire Damper is a critical safety device designed for ventilation and air conditioning (HVAC) ducts where fire compartmentation is required. It remains open under normal conditions to allow for optimal airflow and automatically closes in the event of a fire. This action effectively prevents the spread of flames and smoke through ductwork, protecting lives and property. Once activated, the damper requires a manual reset, ensuring the system is safely inspected before returning to operation.

Fire Damper Used for Cleanroom Ventilation System AHU

** for Air Supply & Exhaust

Dual-Action Closure: Ensures reliability through both manual closure via a pull-rod/rope and automatic thermal activation at a fixed temperature (70°C or 280°C）.

Fuse Like: Features a fusible link that melts at a standard temperature rating of 70°C or a high-temperature 280°C, triggering immediate and automatic closure to block fire spread.

Optional Remote Monitoring: Can be equipped with a status signal switch to send a damper-closed signal back to your central fire control panel, providing crucial operational feedback.

Status: opend as usual. The fire damper can be reset to turn on by hand.

Simple & Robust Design: It offers fail-safe operation independent of power sources. It is purpose-built for fire protection and does not include airflow regulation functions.
