Maintenance-free, ultra-compact complete mask with permanently integrated filters according to EN 405: 2001 + A1: 2009. The half mask is ready for immediate use and offers maximum freedom of movement thanks to its low profile, making it easy to combine with additional protective equipment. The exceptionally large field of vision enables focused work. The mask features permanently integrated A1 filter cartridges and P2 R D filters, whereby the folded filter technology more than doubles the surface area of the particulate filter. This leads to a clearly noticeable reduction in breathing resistance and increases the holding capacity and service life of the particulate 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 vapours with a boiling point > 65°C (max. concentration 0.1 vol. %), as well as non-toxic dusts and water- and oil-based aerosols. Additionally, it protects against CMR substances and airborne biological agents of risk groups 2 and 3, subject to a risk assessment.
