Production of smoke exhaust and fire damper

Smoke exhaust fire damper, a fire-fighting component, is generally installed on the pipes of mechanical smoke exhaust systems. It is usually in a closed state and opens for smoke exhaust in the event of a fire. When the temperature of the smoke in the smoke exhaust pipe reaches 280 degrees, it closes and meets the requirements of smoke leakage and fire resistance integrity for a certain period of time, playing a role in smoke isolation and fire resistance.

Advantages of fire dampers

1. Low air leakage and good air tightness performance;

2. Electric opening consumes less current;

3. Strong anti-corrosion performance and long service life; (Material is stainless steel type)

4. The actuator drive is flexible, and the feedback and interlocking signals are accurate.
