While at the Electric Power show this week I seemed to hear this alot: “Why can your vacuum handle coal dust when my shop vacuum won’t?” That seems to be a big question in the industrial vacuum cleaner world. Whether its coal dust, wood shavings or some other fine dust or debris, people want to know just what exactly an industrial vacuum has that their shop-style vacuum does not. Well, not being sold on the shelves of your local hardware store is just beginning.
