Full face mask with Universal connection, according to EN 148-1, and face seal made of thermoplastic rubber. The anti-fog system is designed to avoid visor fogging through the control of the cold and hot air flows inside the mask. It is equipped with a double front exhalation valve to increase comfort by reducing breathing resistance during use. Its compact dimensions provide an excellent distortion-free field of vision through the visor, in polycarbonate or glass. Thanks to overmoulding production, the number of components is extremely reduced, enabling quick and easy product maintenance. Fixed on 6 connection points, the harness guarantees a highly precise adjustment by distributing the pressure on the face uniformly. The visor of the BLS 2150V model is made of tripartite glass, stratified with an anti-fragmentation EVA layer, to ensure maximum safety during use. It is most suitable for providing high resistance to chemicals. It is compatible with BLS 400 series filters.
