The W1 AIR-EX 1/3D is an ATEX-certified industrial vacuum cleaner for safe extraction of dust and solids in medium and high explosion hazard areas. It provides high filtration efficiency due to the double level of filtration, which prevents explosion risks and spillage of the sucked-in material into the surrounding environment. Power is provided by a powerful 7- or 14-nozzle maintenance-free Venturi unit, with an outstanding balance between air consumption and performance.
