Code Certified Stainless Steel Air Dampers
Along with our own stainless steel air dampers, we can also supply A-60 Certified dampers if your vessel is in survey or needs to meet USCG or SOLAS & are also Register Certified to Lloyds IMO Fire Test Procedures.
A necessary component of an engine room system, these A-60 Dampers are stainless steel and have an automatically controlled release mechanism. They cannot be supplied with mechanical or manual triggers.
Controls for these A-60 rated air dampers are located outside of the duct work for ease of installation and access.
At a temperature of 74°C the fail-safe is triggered and the louvre blades will spring shut closing the damper and preventing any further supply of oxygen to your engine room. The actuator will also trip if the power supply to the system is turned off. The closure of the damper blades will allow your fire suppression equipment the best possible operational parameters.
These stainless steel dampers can be supplied on their own or typically with our Air Intake Grilles and either our High Volume Fans or our Compact Fans for a complete engine room ventilation system.
- These S/S Marine Fire Damper is suitable for both vertical and horizontal applications, with airflow in either direction. They can also be mounted together as a pair in either a horizontal or vertical layout.
- The dampers are tested to IMO fire test procedures Code, Annex 1 Pt 3, are normally open, and fail-safe to the closed position.
- These Dampers are supplied with the blades in the fully interlocked closed position to avoid damage during transit and installation. It is recommended that the dampers remain closed until actual date of commissioning.
- All fire dampers are life safety products and must be treated with care during handling, storage and installation.
