ATEX INERT in the 1/3D category covers specialised immersion and wet-mix vacuum systems designed for the safe recovery of conductive, reactive and potentially self-heating metallic dusts. These units are certified for use in environments with an external Zone 22 classification while providing Zone 20 protection internally. By submerging dust directly into a liquid bath, the system neutralises metal powders and prevents ignition, sparks, thermal runaway and internal hotspots. This category is essential for applications where conventional dry ATEX vacuums are insufficient or unsafe – including aluminium, titanium, magnesium, copper, pyrophoric alloys, 3D-printing metal powders and components from ammunition processes. All models are ESD-safe and require conductive accessories, correct liquid selection and controlled operating procedures.
