This mask is recommended for organic, inorganic, chemical and ammonia based gases into industrial applications, and dust.
The gas cartridges contain specific activated carbon granules with optimised characteristics such as pore size, grain size, activity level, density etc, which provide a maximum adsorption performance and a really low breathing resistance.
Each respirator is supplied pre-fitted with two gas filters that can be replaced. Particulate filters can be added (SPM523 and SPM524)
Efficiency: P3 > 99,95% for 0.3 particulate. At 1000 ppm: Cyclohexane >70 minutes. Chlorine > 20 minutes. Hydrogen sulphide > 40 minutes. Hydrogen cyanide > 25 minutes. Sulphur dioxide > 20 minutes. Ammonia > 50 minutes.
