The NBC-17 SOF 40mm gas mask filter canister, in combination with a full-face mask, mouthpiece assembly, TAPR, or PAPR, reliably protects air passages against a wide range of harmful substances including 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.
IMPORTANT NOTE: Due to the shorter threads, the NBC-17 SOF Filter is NOT compatible with the MB-90 PAPR unit.
NBC-17 SOF GAS MASK FILTER KEY FEATURES:
- Compatible with standard 40mm NATO threaded respirators, which are widely available.
- 10-year shelf life - save money long-term by not having to replace your filters every year.
- Used by military personnel, CBRN specialists, and special operations forces all over the world
- Rated for A2B1E1K1P3 D R.
- Certified by European agencies and has the “CE” symbol. Compliant under EN 14387+A1

NBC-17 SOF GAS MASK FILTER APPLICATION:
The filter provides reliable protection against solid and liquid aerosols, smoke-producing substances, radioactive particles, bacteria, viruses, vapors of organic and inorganic acids, hydroxides, organic solvents with a boiling point above 65°C, ammonia, amines, acid gases, agricultural chemical combustion products, tear-producing agents, irritants, choking agents, blister and nerve agents, (e.g., bromoacetone, CS substance, organic compounds of arsenic, phosgene, hydrogen cyanide, cyanogen chloride, mustard gas, organophosphates) – sarin, IVA, VX and other toxic substances, (e.g., benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulphur oxides, phosgene, phosphoric acid and its organic derivatives, chloroacetic acid, nitric acid, aldehydes, mixtures of inorganic acids and organic substances.)

GAS MASK FILTER LIFETIME:
Breakthrough time of a gas mask 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. 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.
GAS MASK FILTER STORAGE AND MAINTENANCE:
Each NBC-17 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at 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 storage period (month and year) for filters 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.
