Directional Air Diverters

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 Fan 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 powdercoated 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.
