A longtime favorite of U.S. Special Forces groups, the Profile TurboFan™ represents one of the most effective night-vision-compatible weapon against lens fogging. Powered by a single AA battery, the TurboFan™ system draws fresh airflow in through the lower edge of the goggle frame and forces humid air out the top at around 13,000 rpm. Even when perspiration or temperatures are extreme, this two-speed system will exhaust humidity and dramatically reduce lens fogging for over 150 hours of continuous operation (low speed).
