For over 40 years, turbine electric high performance 12- & 24-volt cooling fans for over the road trucks and tractors are still the world’s largest commercial assemblies. Our advanced, single-fan technology offers a wide range of sizes up to 30″ dia., with air flow ratings up to 10,000 cfms.

Most over-the-road trucks can replace the conventional belt-driven fan with a turbine electric fan, provided the engine is under 450 hp and benefits from ram cooling. It should be noted that a successful installation depends on many critical factors, including the condition of the cooling system (engine must not overheat with the conventional fan), gross vehicle weight, alternator capacity and proper radiator core size. The electric fan must monitor water, charge air and air conditioning head pressure.

Our Technical Support Department should be contacted at 800-338-4120 to ensure proper fan selection.

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. Fan operation should be protected from personal and foreign objects.

For over-the-road trucks, select the correct model # and the number of units required from the appropriate application chart. Contact EFE for price, availability, or information on custom designed units.

Units may be installed diagonally across radiator core.Series 3000-5500-6000-6500 models are also available without fan shroud and telescoping mounting hardware.
Custom designed units are available if space limitations are encountered.
On some applications, it may be necessary to use more than the recommended number of fans.
