Dust Ex - Dust extraction Tool for Vacuum. While opening the bag, filling the powdered material or starting the mixing process, it is simply impossible to avoid generating potentially harmful amounts of dust. This can negatively affect workers’ health and lead to contamination of the workplace. This can be a real problem, particularly when working indoors. The dust.EX dust extraction device is simply clamped to the edge of the mixing bucket in combination with a vacuum cleaner. The clamping spring enables attachment to almost any mixing bucket. Switch the vacuum cleaner on for virtually dust-free working while filling or mixing. dust.EX reliably removes any escaping material. Ideal while breaking and pour bags in preparation for mixing.
