Off-Highway Drives VMaster® Viscous Air-Sensing Fan Drives

VMASTER Viscous Air-Sensing Fan Drive

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.

Applications

  • Compressors
  • Compactors
  • Forklifts & Telehandlers
  • Generator sets
  • Agricultural tractors
  • Backhoe loaders
  • Excavators
  • Construction equipment
  • Variety of other off-highway equipment
  • Variety of on-highway trucks and vehicles

Features & Benefits

  • Bi-metal precision sensor provides precision cooling for fuel economy and reduced noise
  • Modulation enables drive to regulate fan speed with minor temperature fluctuations preventing system-damaging temperature spikes
  • Lightweight, modular and fully-sealed construction for long product life
  • Stable crankshaft eliminates need for vibration damper for smooth operation
