| The 09A gas mask is a respiratory protection equipment for the combined forces. It is mainly used for personal protection in nuclear, chemical and biological battlefield environments to protect personnel’s face and respiratory tract from damage caused by radioactive dust, chemical agents and biological warfare agents, and to ensure the safety of mission execution. This equipment can be used in conjunction with breathable anti-gas suits, anti-gas gloves, anti-gas boots, etc., and can also be used in conjunction with individual integrated combat systems. The 09A gas mask is suitable for use in areas attacked by chemical and biological weapons and contaminated by nuclear radioactivity. Main performance and technical parameters (1) Respiratory resistance: Under a constant airflow of 30L/min, the inhalation resistance is not more than 160Pa; the exhalation resistance is not more than 90Pa; under a constant airflow of 85L/min, the inhalation resistance is not more than 430Pa: the exhalation resistance is not more than 120Pa. (2) The total field of view is not less than 70%; the binocular field of view is not less than 20%. (3) Under -25℃ environmental conditions, the effective brightness retention time is not less than 2h. (4) The sound transmission loss is not more than 8dB, and it can be used in conjunction with an electroacoustic intercom. (5) The gas mask can be used normally at a temperature between -25℃ and 35℃. (6) The mask is available in three sizes: S, M and L. (7) The weight of the mask should not exceed 850g. (8) The storage period is 5 years. |
