Caframo Stor-Dry Warm Air Circulator The Stor-Dry low wattage warm air circulator is the must have product for the winterization season. The model 9406 Stor-Dry combats mold, mildew and musty odors in any boat that is closed up or winterized. This dual action air dryer uses a low wattage heating element and internal fan to both heat and circulate the air. The heat and circulation prevents stale air pockets which in turn prevents mold or mildew forming on the interior surface of the boat. Product
