Solar vents provide mechanical ventilation utilizing the solar energy. The solar panel activates the fan which allows the air to flow in. These autonomous vents detect water flows from waves and rain, while refreshing the atmosphere even on those calm windless days. Special balls inside the vents are pushed by the water to shut ventilation holes and ensure impermeability. They have two functions; one function activates solar function and the other one modifies fan’s function from clockwise to counter clockwise turn. Solar vents are made of white plastic, while the 98681 vent is equipped with an Inox plated cover.
