A60 Circular Marine Fire Damper
The marine fire damper consists of two forms: circular and rectangular. A60 circular marine fire damper is usually installed on the air ducts of ventilation and air conditioning systems that need to regulate the air flow, and is suitable for air ducts with horizontal or vertical air flow.
Overview
Circular fire damper is installed in the ventilation, air conditioning system of the supply and return air ducts, usually open state, when the gas temperature in the pipeline reaches 70 ℃ in case of fire, the fusible piece fuses, and the fire damper closes automatically under the action of torsion spring, and it can satisfy the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time, and play the role of the damper to isolate the smoke and block the fire. When the fire damper is closed, the closing signal is output.
Feature:
1. Low air leakage, good airtight performance .
2. Electric opening consumes little current.
3. Strong anti-corrosion performance, long service life.
4. Flexible actuator drive. Feedback, interlocking signal is accurate.
