The improved TurboFan fog elimination system features the robust PowerPod push-button switch, which is now positioned near the back of the head for snag-free operation. A single AA battery powers the two-speed system for 150 hours of continuous operation.

The Profile TurboFan is a compact system compatible with night vision equipment and helmets. Its durable closed-cell OpFoam anti-microbial face padding is easy to clean and extremely comfortable in all weather conditions. The Profile TurboFan from Eye Safety Systems includes both clear and smoke gray lenses, an anti-reflective SpeedSleeve, and a rugged protective case.
