Technical note
Unlike standard Zone 22 or ACD vacuums, the MTL 301 BP 1/3D is third-party certified for internal Zone 20, making it suitable for applications where combustible dust accumulates directly inside the container. This feature is crucial in environments with health and explosion risks such as indoor shooting ranges, where both lead and gunpowder residues must be safely removed. The model is part of our recommended solution for Daily cleaning on shooting ranges – without sparks or lead dust.
