The DM3 AIR compressed air industrial vacuum cleaner is the ideal solution for sucking up dust, and solids mixed with liquids in places where compressed air is preferable to electric energy and where high powered suction is needed. 2 potent, compressed air-driven Venturi units, with no need for routine maintenance, generate the suction. The high capacity polyester filter with handy manual filter shaker guarantees an excellent level of filtration. The large 100 litre detachable container ensures there’s plenty of collection capacity. Also available in electric version.
