H2Out™ AVDs (Air Vent Dryers) prevent moisture from entering the tank, eliminating condensation, sludge build up, plugged fuel injectors, preventing fuel tank and engine corrosion. Fuel and fluid storage without chemical stabilizers is possible now with the H2Out™ AVDs installed in the air vent lines. Winner of the 2012 Pittman Innovation Award, H2Out Systems is now packaging its drying media in ways that are particularly relevant to the sailboat owner. When the dryer media, which is infinitely reusable, changes from blue to pink it’s time to dry it out again using just a conventional oven.
