HT/S Advantage™ On/Off Pneumatic Fan Drives for Off-Highway Engines

We started with a technologically advanced hub bearing assembly optimized for durability. We added a PFD (Piston Friction Disc) featuring the System Sentry®. This patented device reacts to heat build up caused by fan drive slippage or fan obstructions. When it senses excessive heat, the System Sentry releases, disengaging the fan drive before extensive damage occurs to the cooling system.
