With its simple yet robust design, Curtain type Fire damper (PFDC) is used to localise areas of fire in ventilation systems and thus impeding the spread of fire and hazardous gases.
The design principle based on interlocking blades that closes under gravitation force when the connecting thermal link breaks at set temperature.
With interlocking blades design, the damper provides the maximum free area and imposes minimal resistance to air flow system.
