Automatic Shelter Vent Kit

Keep your shelter cool and dry with ShelterLogic’s AutoVent, the ultimate ventilation system for your shelter. The vent automatically opens and closes based upon the interior temperature. Reduce humidity and moisture buildup in your fabric garage or shelter. A bimetal spring, which is heat sensitive, begins to open the vent at 74 degrees Fahrenheit and it is fully opened at 104 degrees. When the interior temperature cools down, the vent begins to close up.
