HT/S Advantage On/Off Pneumatic Fan Drives

Air-Engaged Fan Drives

The HT/S Advantage is perfect for high run time applications.

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.

Finally, we included a new air cartridge with a long-life carbon tip and double O-ring air seal to reduce the possibility of air leaks.

The bearing assembly design, PFD with System Sentry, and air cartridge, combine to provide you with a premium on/off fan drive that will perform consistently under extreme conditions - exactly the sort of performance you've come to expect from Horton!
