Air-Sensing Fan Drives

Viscous Air-Sensing Fan Drives

The VMaster viscous air-sensing fan drive works smarter so your engine can work harder. Equipped with a bimetal precision sensor, the viscous air-sensing fan drive delivers the right amount of cooling required. A fan that operates at maximum speed only when cooling requirements demand it can cut fuel costs significantly over the life of the vehicle.

Modulation enables the drive to regulate the fan speed between idle and maximum rotational speed depending on the air temperature, quickly responding to even small temperature fluctuations. This prevents temperature spikes while reducing the need for the fan to run at full speed. There is less likelihood of thermal shock damage, and noise levels are noticeably lower.
