509 Anti-Fog Goggle Fan

The 509 Anti-fog Fan stops fog dead in its tracks. If you are a sweat or just want an extra level of fog-stopping protection, the 509 Anti-fog Fan is for you. This is a removable fan module that installs directly into your existing pair of 509 goggles and was specifically engineered to work with both 509 Sinister X5 and 509 Aviator Goggles.

Once installed in your goggles, the fan module has 3 settings. Off, On, and Auto. The auto setting automatically detects fog and turns on the fan only when needed. Just set it on auto and let the module do all the work. The fan works by pulling moisture from inside the goggle and pushing it out the top of your goggles. When the moisture level drops to an acceptable level, the fan will automatically turn off. The fan is powered by one AAA battery.


  • Designed specifically for most 509 goggles
  • Automatically senses and removes fog
  • Does not restrict vision
  • AAA battery included

Note: Does not fit 509 Kingpin Goggles.
