Doppstadt Inventhor 9
The INVENTHOR 9 opens up completely new possibilities for effective shredding. From material feeding to discharge, it impresses with a range of innovations, including the new VarioDirect Drive, which delivers continuous power while reducing load on the motor, and the redesigned housing, providing optimum accessibility from all sides. No matter the material, the INVENTHOR 9 offers a top-tier solution for even the most demanding applications.
For enhanced versatility, the DoppBasket system is available as an option. With coarse or fine strip baskets, a wide variety of materials can be shredded consistently and at high quality. The DoppBasket system is ideal for waste and green waste, and is also highly effective for special applications such as mattresses, tires, carpets, fishing nets, or plastic pipes.
