For Use on Airdog Air/Fuel Separation Systems.


The AirDog replacement water separator WS100 is a direct replacement for your AirDog fuel system. The built-in drain allows you to empty any water from the filter during routine maintenance. The life expectancy for the AirDog water separator could be up to 25K miles or a year. However, those figures can change drastically depending on fuel quality. Order a few extra and keep them in your cab or toolbox.
