Marine Engine Room Air Dampers (Fire Flaps)
Typically Air Dampers are either triggered automatically or manually, and effectively close the air supply to the engine room to allow fire suppression equipment to work. We can manufacture and supply Air Dampers (Fire Flaps) either in conjunction with our Air Intake Grilles, or supplied on their own.
They can be mounted immediately rear of the grilles, within the duct work itself, on the bulkhead or deck head penetration, or any penetration that serves air into or out of the engine room.
Our Air Dampers come with a control cable that runs from the damper to an external location outside of the engine room space. This manual control is easily operated by disengaging the pull ring from the keeper bracket. This action trips the spring loaded damper louvre which closes off the air supply to your engine room. They are also available with a semi auto control. If there is fire or intense heat in the vicinity of the control cable (which is a synthetic material), the cable will melt and trigger the flap automatically.
If you use an Air Damper system, you will need to test and prove the system annually for a surveyor. To reset after this test simply re-pull the cable and re-engage the ring into the keeper bracket. It's very easy.
