BorgWarner DuroSpeed 2-Speed Fan DriveBorgWarner’s DuroSpeed 2-speed fan drive is designed to deliver cooling for severe operating and vocational truck applications such as construction vehicles and municipal trucks. The pneumatically actuated fan drive is built to reduce engagements for less noise, increased clutch life, minimal dust buildup in the radiator and more available horsepower, allowing the vehicle to achieve higher work output. Its flux ring design is engineered to run cooler, facilitating added bearing and liner durability, while a higher disengaged fan speed helps to prevent engine temperatures from rising too quickly. The fan drive has no spinning air connections to wear, inspect or service.
