Marine Air Flow International

Marine Compact Fans

Compact DC Engine Room Fans:

Our DC Compact Fans can now be purchased directly in our new Marine and Industrial Fans Online Store. 

Our DC fans have a smaller footprint and physical volume making them ideal for tight locations. They are significantly more cost effective, easier to install and wire. They do not handle significant pressure and have limited volume capacity (supply volume) at higher pressure. They can be banked (multiple fans installed together) for larger applications although in this situation our AC/DC High Volume Fans would probably be a better option financially. 

These DC Axial Fans are available in either 9" or 12" options. Both are available in 12 Volt or 24 Volt DC only.

As a general rule of thumb you could work on a single 9 inch fan per 150 HP and a single 12 inch fan per 450 HP.
We also supply mounting brackets for the 9 or 12 inch fans which are available in 45 degree or 90 degree angles and come complete with a finger guard. Mounting plates to attach these fans onto our Air Dampers are also available.

We can also supply Air Diverters to control the direction of air produced by the fans along with an Air-On-Demand system to control noise and air volume.
