Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30☌ and relative humidity below 80%. The filters are sealed in plastic bags by the manufacturer. The approximate lifetime (usage time) of a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter. LIFETIME:īreakthrough time of a filter is tested according to EN 14387+A1 at humidity 70% and flow rate 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium heavy work. benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulphur oxides, chloracetic acid, aldehydes, mixtures of inorganic acids, and organic substances, mercury vapours, radioactive iodine, organic compounds of iodine (Iodomethane, 129, 131), radioactive particles, etc. The filter canister in connection with suitable respirator or PAPR provides protection against solid and liquid particles, pepper spray (OC), smokeproducing substances, radioactive particles, bacteria and rickettsia, fungi, toxins, viruses, Riot Control agents (Lachrymators, Sternutators, Vomiting agents), Blister agents (Vesicants), Chocking agents, Blood agents, Nerve agents, Incapacitants, Herbicides, Pesticides and TIC, such as bromoacetone, CS, CR, CN, CNC, CNS, CA substances, organic compounds of arsenic - diphenyldichlorarsine - CLARK I (DA), diphenylcyanoarsine - CLARK II (DC), adamsite (DM), diphenyldichlorarsine (DA), ethyldichlorarsine (ED), methyldichlorarsine (MD), mustard gas (H), sulphur mustard gas (HD), T-mustard gas, Q-mustard gas, nitrogen mustard gases (HN1, HN2, HN3), lewisite (L), mixed mustard gas (H-L), phosgene oxime (CX), phosgene (CG), diphosgene(DP), chloropicrin (PS), hydrogen cyanide (AC), cyanogen chloride (CK), arsine (SA), G-agents: sarin (GB), cyclosarin (GF), soman (GD), tabun (GA), IVA (GV), V-agents: VX, VR, VE, VG (amiton), VM and toxic industrial chemicals such as: fumes of organic or inorganic acids, hydroxides, organic solvents with the boiling point above 65 ☌, ammonia, amines, inorganic and acid gases, agricultural chemical combustion gases, other toxic substances, e.g. It provides a very robust product which is extremely durable against shock and impact damage in operational use.
