Our activated carbon in form of grains is of type AG. The grains have a cylindrical shape with diameter O3-4 mm and density 600kg/m³. They are appropriate for the clearance of atmospheric air or other gases with medium-low organic contamination. The pores of the grains are responsible for the absorption of organic substances which transfer the odors. The filter can separate chemical substances from gasses coming from paints, or a kitchen, trapping in that way their odors. The activated carbon grains can fill in cylindrical canisters which in arrays are synthesizing the antipollution filter system.
