The posfiltro Microfilter of Losma uses to delete the bad or harmful smells that derive of the some processes like the induction, the spark-erosion with dielectric liquids, etc. The particles contaminantes are fixed by absorption in the surface of the grains of active coal that, thanks to a special process of activation, presents an internal surface of more than 950 m2/g. Thanks to this particular characteristic, the active coals can absorb particles with lower dimensions of 0,1 µm and gases. The posfiltro of active coals can use jointly with other products like the electrostatic filter and the filter in fibre of glass, to delete in the same time fogs, sequipment, smoke and smells. Periodically it is necessary to proceed to the replacement of the coals activated present in the dressings cylindrical containers. The frequency of such intervention depends on diverse factors like the chemical characteristics-physical of the contaminante; the discharge of the contaminante to delete in the unit of time; the sum of the turns of work; the characteristics of the environingingment of work. Indicativamente The coals activated can absorb a quantity of contaminante until 20% of his own weight. The coals are efficient until when, from the cylindrical containers, do not go out smokes neither smells.
