Product data sheet SilentShark 401 Windgenerator The German inventor of the "Silentwind" has significantly further developed the wind generator, focusing on improved safety, even lower noise and optimized performance. The result is the new SilentShark S401 wind generator. The most important part of a wind generator are the rotor blades as drive. These must withstand all air forces, be UV-resistant and quiet. This promises a low-vibration operation. Our rotor blades made of carbon fiber are highly professionally handcrafted in Thailand under German management and for safety reasons painted in two colors for better visibility for humans and animals.
