Our Solar Attic Fan
Roof Air Fan will start and keep running once sunlight is available, own to it is equipped with a best motor. This engine is IP68 waterproof, to assure the fan be suitable to install anywhere!


















* The high energy efficiency feature in our motor supports the fan start running once solar panel input reaches 9V in the morning, and it keeps running until solar panel output drops down to 9V in the afternoon!* Since IP68 waterproof, our fan is guaranteed to work well in a long run, even in those special environments like greenhouse / water tanks, etc., while other similar items can not do!

This solar attic fan is an axial flow type roof ventilator, but it is made with a 360-degree swirl turbine air ventilation structure to guarantee no backward air flow from the exterior. This is essential & beneficial!
















* The wind guide cone with 24pcs wind guide blade structure is held a patent by us, to effectively support the interior hot air be extracted out and no any counterforce to reduce the fan efficiency!* The axial flow type 7pcs fan blade structure is uniquely made from nylon-fiber-aluminum, to upgrade the fan
system with better performance and in quieter operation!

The fan motor engine is connected with solar panel & AC/DC adapter, 2 circuits, and it will run immediately once sunlight is available. Magically, as long as sunlight is sufficient there, AC/DC adapter will not supply power, which means AC/DC adapter will not consume grid electricity when solar panel is working!
























* integrated-assemble on the fan cover, receives sunshine to power motor directly when sunlight is available* plug to a wall socket by 3m cable, through connection with grid circuit to serve as energy backup when sunlight is unavailable






















if solar panel is supplying direct power at X%,
AC/DC adapter will be at (100-X)%
