Gas Mask
Specifications
1.Commodity
Gas Mask Model 1608-D
2.Application
It is mainly used for respiratory protection of operators in non-war military operations, such as nuclear, biochemical emergency rescue, secondary nuclear, biochemical disaster, earthquake relief, etc.
Also used in agriculture, petroleum, petrochemical, chemical industry, light industry, machinery manufacturing, building materials, municipal construction and other industries workers respiratory protection.
3.Standard
Ø GB 2890-2009
Ø GB 2626-2006
Ø BS EN 136:1998 / 134
4.Main features
1. Main mask adopts advanced silica gel one-time molding, which is light in texture, comfortable and durable, and easy to clean and maintain;
2. Headband is made of six-point nylon material with high toughness, good elasticity, comfortable wearing and easy adjustment;
3. Connect 2-level filter (tank type) for wider use, safer and more effective;
4. Unique louver design is adopted on the exhalation valve cover to exhaust on all sides with less exhalation resistance;
5. Perspective visor designed with large view window provides better field of vision.
High performance polycarbonate material, anti-scratch, wide visibility, safer operation;
6. The built-in efficient microphone is combined with the exhale valve, which is more conducive to the transmission of sound and improves the overall safety of the mask;
7. The filter is made of highly efficient chemically impregnated activated carbon and electrostatic electret filter material, which can effectively absorb more harmful gases and efficiently filter all kinds of toxic gases and all kinds of non-oily or oily particles.
High safety, reliability, easy maintenance, good environmental adaptability, long service life;
8. On the premise of ensuring that the protection performance is better than the national standard requirements, reduce the leakage rate of the comprehensive cover to below 0.05%, ensure that harmful gas can only be inhaled through the filter pieces, make the filter pieces play the filtering role to the maximum extent within the effective protection time, and improve the overall protection performance of the gas mask;
9. Mask respiratory resistance as required by national standards, to ensure users breathe more smoothly, greatly reducing the labor load.
