Air Dampers are a necessary requirement for the engine room of any commercial in-survey vessel, and are also a good idea on non survey craft.
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, our High Volume Fans or supplied as a stand alone product.
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 can also be supplied 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. This is also 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. This manual activation kit is available for $250 + gst.
For a fully automatic system, we can supply the dampers with a 24V DC actuator. This actuator works via a temperature probe mounted in the air stream, and once the probe reaches 72°C it will shut the damper automatically. The actuator will also trip if the power supply to the system is turned off. These automatic controllers are a great option for a set and forget situation ensuring full peace of mind. These auto activation kits are available for $825 + gst
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.
If your vessel is in survey and you need to meet a certification level, we can also supply A-60 class certified air dampers
