Turbine Electric Fans for Over-the-road
Trucks |
A Unique System for Diesel Engine Cooling
Most over-the-road vehicles that benefit from ram air cooling (air forced
through the radiator by the vehicle's motion) may use the Series 3000, 5500, 6000, or 6500
Turbine Electric Fans to replace their conventional belt-driven fans. |

 |
  TWO SYSTEMS TO
CHOOSE FROM
EFE can supply single or low profile dual fan assemblies. Single fan assemblies
are recommended for difficult cooling applications that require the maximum amount of air
flow. They are quickly installed since only one unit is required.
|
|
|
|
EASY INSTALLATION Most
kits are fully assembled (Series 6000 and 6500 are semi-assembled) and contain fan blade,
motor, steel fan shroud, and may be easily attached to the frame of the radiator by
utilizing our unique telescopic mounting hardware. |

*Units may be installed diagonally across
radiator core.
Series 3000-5500-6000-6500 models are also availiable without fan shroud
and telescopic mounting hardware.
Custom designed units are availiable if space limitations are encountered.
On some applications, it may be necessary to use more than the
recommended number of fans.
The above information is provided as a guide. The user assumes all
responsibility in the final selection and use of products. |
