Brand NEW 30W Dual Solar Fan for Outside Greenhouse, Shed, Chicken Coop... with IPX7 Waterproof Solar Panel Fan kit This 30-watt solar panel dual fan kit is a great solution for small chicken coops, greenhouses, sheds, pet houses, and window exhaust during hot summer months. The fan can effectively discharge hot air, draw in cold air, lower the indoor temperature, and maintain fresh air circulation. The fan motor (PCB board/wiring/bearings) is coated to prevent damage from short circuits or rain. With a waterproof rating up to IPX7, it is suitable for outdoor environments. The double fans are equipped with a double-layer metal protective mesh to prevent small animals from being injured while ensuring the normal operation of the fan blades. There are reserved holes on the back of the solar panel, which can be designed and installed by yourself. It is practical and convenient just to face the sunlight directly. The solar fan comes with an 8.2-foot extension cord and can be installed in greenhouses, chicken coops, sheds, dog houses, window vents, barns, cowsheds, treehouses, attics, and anywhere else, suitable for indoor and outdoor environments. Please NOTE - Fan speed is greatly affected by sunlight. When the solar panels are exposed to direct sunlight, the fan speed can reach 3000 RPM. In weak sunlight, the fan will slow down or even stop running. Solar fans do not have a built-in battery and can only work during the day. See pictures for more item details. Trusted Seller-Fast Ship!
