Fan Mounted Adjustable Air Diverters
We now manufacture and supply directional Air Diverters that mount directly on the discharge side of our high volume or compact marine fans. These diverters can be supplied for both our High Volume Fans and our Compact fans.
Air Diverters are ideal for directing the air supply toward specific engine room equipment for the purpose of supplying extra fresh air to that component. This enables you to supply air to a specific location in your engine room that may not currently be in the main stream air supply.
High Volume Air Diverters


The High Volume Fan diverters are custom designed for each application and are manufactured from marine grade aluminium. They are proportional to the size of the fan that is being used.
Mounting plates are available for attaching the diverters to our air dampers. These Air Diverters are adjustable so as to be able to direct the airflow into the desired location in your engine room.
Compact Fan Air Diverters

Our compact fan Air Diverters are supplied in a clip on - clip off manner. Each diverter can be twisted and removed from the fan itself, rotated 30 degrees and reconnected. This enables you to mount the fan with the knowledge that you can, if necessary, change the direction of the airflow in two simple steps.
Our compact fan diverters are supplied powder coated black to match the fan housing.

Neither our High Volume Fan diverters or our Compact Fan diverters significantly change the air flow output from our fans. You can add the air diverters and be secure in the knowledge that they won't reduce air flow or affect your ambient change out.

Why Divert The Air In Your Engine Room?
There are multiple reasons why you would benefit from directing the air that is coming into your engine room, however the main ones are:
Directing the air towards a particular engine room component.- Ensuring correct air flow travel through your engine room
- Assists with intake and outlet exchange air rates
- Can help to mitigate the cost of fans in some installations
