High Volume Marine Fans

Marine Engine Room Fans:

Our AC or DC high volume fans are perfect for the purpose of assisting in the induction of air into and around your engine room.


Combustion engines require air to produce horsepower, to support combustion, and for cooling purposes. In a traditional marine engine room with natural aspiration (ie: no fans), the only air movement is due to the air being consumed to support combustion. Very little additional air enters or leaves the engine room. Without fan forced air being inducted into your engine room, the space gets warmer and warmer, forcing your engine to draw warm ambient air which is far from an ideal situation.


With fans introducing new cool air into your engine room you will enable all your engine room equipment to work more efficiently, while extending the mechanical life of this equipment.


We can also supply Air Diverters to control the direction of air produced by the fans.


Our AC or DC High Volume Fans are best suited for high pressure situations and applications. These fans are designed for a longer service life and will be suitable for larger engine rooms with high levels of running time. 

Why Engine Room Fans?

How our fans can help:
  • Cooler operating conditions which can lead to increased performance.
  • Can extend the life of valuable plant and engine room components.
  • Custom made to suit your requirements.
  • Supplied with full installation kit and instructions.
  • Variable speed controllers available as an optional extra.
