Marine Dampers: Control, Safety, and System Efficiency

What Is a Fire Damper?

A fire damper is a mechanical device used to close off airflow in a ventilation duct. It ensures that air moves where it’s needed—and stops it where it’s not—especially during emergencies like fire or gas leaks.

Why Dampers Matter at Sea

Marine environments demand reliable airflow control. Dampers help:

Control air movement in HVAC and machinery systems
Shut off air supply in case of fire or system failure
Protect compartments from smoke, gas, or fire spread
Meet strict safety and compliance standards
