Instrumentation Anti-static equipment Inspection Detection For the purpose of doing an optimum dusting of a film, it is imperative to implement three indissociable actions: > - A mechanical force to separate of the particles from the support, - An ionisation of the air to eliminate the electrostatic attraction, > - A suction to remove the particles. We find these three actions associated in the ECOVAC 5 ionising dust extractor. > The mechanical action by a scraper placed at the centre of the suction slits makes it possible to lift away the p articles from the film, revealing their electrostatic charge. Its central position, between the suction slits, guarantees an optimum dusting quality. > The ionisation of the air cancels out the electrostatic phenomenon of adhering. This is done by the CORONA effect. Each ionising point > connected to high voltage generates an electrical field charged with positive ions and negative ions (electrons). When the material being treated is under the influence of this electrical field, a transfer of electrons (negative ions) is produced until the charges are neutralised on the surface of the material. On the > ECOVAC 5 ionising dust remover, the ionisation points are connected by a capacitor device to the high voltage source, thus limiting the current at a few micro -amps. These appliances therefore present no danger in the event of contact with the switched -on points. Two suction slits, placed on both sides of the scraper, allow the collecting of particles in accumulation. The ECOVAC 5 ionising dust extractor satisfies the most stringent specifications. It integrates the notions of good practices in matters of health and safety of the foodstuff and pharmaceutical industries. The ECOVAC 5 ionising dust extractor was designed in complete > compliance with the environmenta l constraints of the foodstuff and pharmaceutical industries. Its disassembling, for daily cleaning operations, does not require any tool. Moreover, the equipment is assembled without any screw or removable components. This means that there is no risk of los ing of any part liable to contaminate the products to be treated. >
