GAS MASK FILTER LIFETIME:
The breakthrough time of a gas mask filter is tested according to EN 14387+A1 at a humidity of 70% and a flow rate of 30 l/min, equivalent to the volume of air per minute used by an average person carrying out medium-heavy work. The approximate lifetime (usage time) of a filter may, under normal conditions, be calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.
GAS MASK FILTER STORAGE AND MAINTENANCE:
Each NBC-77 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at an even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The filter's storage period (month and year) is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.
GAS MASK FILTER DISPOSAL:
After use, gas mask filters are considered special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.
The NBC-77 SOF gas mask filter is unique because it combines the abilities of three filters in one without making any compromises.
Typically, agencies would have to stock a CBRN filter for chemical warfare agents, an industrial filter for toxic industrial chemicals, and a Reactor filter for radioactive iodine.
Traditionally, CBRN filters were not very good at filtering out toxic industrial chemicals, industrial filters did not work for CBRN, and Reactor filters were solely for filtering out mythyiodide131 or methyliodide129 gas.
This made it difficult for agencies, logistically, to stock a different filter for each type of threat. With the NBC-77 SOF, users can now use one filter for all three types of threats, simplifying logistics and saving money with an extended 20-year shelf life.
Radioactive iodine (its organic compounds - mythyiodide131 or methyl iodide 129) are mainly created during reactions in nuclear power plants. Therefore employees of power plants and people who live nearby a nuclear power plant need to be protected in case of leakage.
Reactor filters are also used in nuclear research institutions and also during the transportation of nuclear material to hospitals where it is used for radiotherapy (for patients with cancer).
Reactor filters are also needed by first responders, police, and military for cases of accidents during the transport of nuclear materials or waste and cases of misusing radioactive materials by terrorists (dirty bombs).
NBC-77 SOF GAS MASK FILTER APPLICATION:
The filter canister in connection with a suitable respirator or PAPR provides protection against solid and liquid particles, pepper spray (OC), smoke-producing substances, radioactive particles, bacteria and rickettsia, fungi, toxins, viruses, riot control agents (lachrymators, sternutators, vomiting agents), blister agents (vesicants), choking 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 a boiling point above 65° C, ammonia, amines, inorganic and acid gases, agricultural chemical combustion gases, other toxic substances, e.g. benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulphur oxides, chloroacetic acid, aldehydes, mixtures of inorganic acids, and organic substances, mercury vapors, radioactive iodine, organic compounds of iodine (Iodomethane, 129, 131), radioactive particles, etc.
The NBC-77 SOF filter canister, in combination with a full-face mask, mouthpiece assembly, or PAPR, reliably protects air passages against a wide range of harmful and highly toxic substances, including all known CBRN agents.
The filters are produced with standard round threads according to STANAG 4155 (EN 148- 1)- Rd 40x1/7". The filter components are made of hard plastic. This results in a very robust product that is extremely durable against shock and impact damage in operational use.
