MODULAR FILTRATION COLUMN FOR GASES AND PARTICLES (according to NFX 15-211:2009) CLASS 2 Type G Handling of liquid compounds/products FILTRATION COLUMN FOR POWDERS Molecular Filter HEPA-H14 Filter Type GS Handling of liquid and particles compounds/ products Fan Type D Handling of powder compounds DUCTLESS FUME HOOD FILTER TYPES Type A Type K Type F Type BE Type D Type ABEK For organic vapors such as ketones, ethers, alcohols, xylenes ... Eventually it can be used for inorganic acids, but only if used in small quantities because this activated carbon is not impregnated and the excess of acid vapors could saturate it quickly. For NH3 vapors and amines; also good for other organic compounds. Carbon with metal salt complexes impregnation. For formaldehyde vapors and derivatives; also good for other organic compounds. Carbon impregnated with Cu leads, so that it should never be used with inorganic acid vapors. For inorganic acid vapors as H2SO4, HCl, HNO3, and volatile sulfur compounds such as H2S, SO3, ... It can be used with organic vapors because the activated carbon incorporates impregnation of metal compounds and neutralizing salts. It is also suitable to filter organic and inorganic compounds when they are in similar proportions. HEPA H-14 filter (High Efficiency Particulate Air, according to EN-1822: 1998) for filtering dust and smoke particles. Mixed type to be used when the ratios between organic, inorganic and NH3/amines are similar.
