RGS Impianti is paying specific attention to this constantly developing sector. The industrial vacuum cleaners find application especially for the cleaning of incinerators and furnaces. The vacuum cleaners must be able to work for a long time and to suck up huge quantities of ashes or very fine dusts, sometimes even with elevated temperatures. For these purposes, we suggest using two units: the pre-separator (available with different types of discharge) in which most of the collected material will settle and the suction unit fitted with high-efficiency filters, where only the more volatile dusts come.
