This connection is very intuitive, it allows a fast and safe fastening of the protective mask. It has a locking mechanism that allows the user to know if the filter has been placed correctly. The double filter offers better weight distribution on the mask and a wider field of vision.
The quality of the activated carbons used by BLS for the filtration of gases and vapours meets high standards of safety ensuring excellent filtration performances. They are produced without toxic additives such as Hexavalent Chromium (Cr VI).
BLS has carried out specific NIOSH tests in an accredited Laboratory to verify the penetration of Formaldehyde in its carbons used for the ABEK and ABE filters.
◉ A Organic gases and vapours with boiling point > 65 ° C
◉ AX Organic gases and vapours with boiling point ≤ 65 ° C
◉ B Inorganic gases and vapours (e.g. chlorine, hydrogen sulfide, hydrogen cyanide)
◉ E Acid gases and vapours (e.g. sulfur dioxide, hydrogen chloride)
◉ K Ammonia and derivatives
◉ Hg Mercury vapour
P Particles, mists, fumes
