Finding supported by an article from the Ministry of Labour, food, plant, metal or industrial dust is considered to be bothersome or dangerous to health; they can indeed cause respiratory discomfort, allergenic and even toxic effects on the body. In addition, all combustible dusts are capable of causing an explosion. The recommended means of prevention are to work wet, to use an industrial vacuum system or to use personal protective equipment. Wam France thus offers to moisten the dust using Dustfix, with a view to being recycled in production or for external revaluation, by handling it without a cloud of volatile dust. This device, on leaving the dust silo, injects water or a binder on the dust, mixes it in a patented non-stick and anti-abrasion polyurethane chamber, then drains it, still in powder form, into all types production or in an open skip. Able to treat from 5 to 80 m3/h, the Dustfix range pays for itself very quickly.
