NORBLAST S.R.L.: They are manual machines, equipped with a blasting system operating under vacuum conditions (SD Line) or under pressure conditions (SP Line) offering great versatility in compact sizes; in fact they integrate a grit blasting and recovery system, as well as a dust filtering device. Simple to use and quick to install, these machines are immediately ready for work! The selection and recovery of the abrasive take place automatically in the cabin by means of a suitably sized chimney vent that conveys the crushed grit and waste dust towards the filter and keeps the usable grit in circulation, all with the aim of reducing waste and wear to a minimum. All the Compact machines are also equipped with an integrated filtration system with self-cleaning cartridges, which has the important task of removing dust from the work cabin, to eliminate the crushed material and to make sure that the micro-dust is not dispersed into the surrounding environment.
