BorgWarner DuroSpeed Two-Speed Fan Drive

BorgWarner's DuroSpeed two-speed fan drive is specifically designed to deliver reliable cooling for severe operating and vocational truck applications such as construction vehicles and municipal trucks.

• Reduces fan engagements for greater reliability and less noise in severe service applications
• Modular design allows any BorgWarner Kysor on/off fan drive to be easily converted to a DuroSpeed fan drive
• Flux ring design enables to run 70 F cooler than competitive offerings
• Cooler internal operating temperature increases bearing and liner durability, allowing nearly twice as many engagements over its lifetime
• Pneumatically actuated with a higher disengaged fan speed to prevent engine temperatures from rising too quickly
• Reduced engagement and disengagement increases clutch life, decreases noise, minimizes dust buildup in the radiator and makes more horsepower available, allowing vehicle to achieve higher work output
• Contains no spinning air connections to wear, inspect or service
• Operates at lower temperatures for longer bearing and liner life
• Weighs 5 to 10 lbs. less and uses 11 fewer components than comparable units to help deliver better fuel economy
• Uses same clutch unit for all applications to reduce complexity and minimize upgrade costs
• Any Kysor on/off fan drive can be easily retrofitted to a DuroSpeed fan drive with a conversion kit consisting of only two add-on components
