Maintenance-free, ultra-compact complete mask with permanently integrated filters in accordance with EN 405: 2001 A1: 2009. The half mask is ready for immediate use and offers maximum freedom of movement thanks to its flat profile, making it easy to combine with additional protective equipment. The exceptionally large field of vision enables focused work. The mask has permanently integrated A1 filter cartridges and P2 R D filters, which more than double the filter area of the particle filter thanks to the pleated filter technology. This leads to a clearly noticeable reduction in breathing resistance and increases the absorption capacity and duration of use of the particle filter. An additional pre-filter is not necessary. The mask meets the requirements of EN 405: 2001 A1: 2009 and is suitable for protection against organic gases and vapors with a boiling point of 65°C (max. concentration 0.1 % by volume), as well as non-toxic dusts and aerosols based on water and oil. It also protects against CMR substances and airborne biological agents in risk groups 2 and 3 if a risk assessment is available.
