The “AD” series of compressed air vacuum cleaners are ideal for environments where electricity is not allowed or unavailable. These vacuums operate using compressed air and have no moving parts, creating suction through a “Venturi” system. The X1-X2-X3 versions of these vacuums can be used in hazardous areas classified as zone 21-20 internally and are marked EX II 2/1D. The AD series is equipped with a Venturi ejector, an antistatic star filter with a diameter of 360 mm, and a removable 25-liter container made of stainless steel. Despite its powerful suction capabilities, this vacuum has a compact size, making it the smallest model in the range of compressed air machines.
