BLS Zer0 FFP3 disposable mask

An ultralight membrane concentrates the exhaled air into two zones of maximum aperture, 30% wider than before. With these improvements breathing resistance decreases significantly.

It is an external protective layer that ensures the protection of the filtering material from dirt, dust and liquids as well as the normal mechanical stress due to prolonged use thus extending and preserving filtering efficiency and making the device safer.

Made with a new soft technical foam, which allows an excellent fit on any face and guarantees a high comfort on contact with the skin.

The nose clip, placed internally between the layers of filtering material, adapts optimally to the profile of the nose and eyes, ensuring good visibility and maximum compatibility with glasses.

An activated carbon layer may be added to the respirator to protect from nuisance odours caused by gases and vapours, both organic and acidic, including ozone (ideal for welding operations), in concentrations below the threshold limit value (TLV).

The ratio of transmission of water vapour through the material is 3500 g/m² 24hrs. A value that defines materials of a high transpiration range which makes it ideal for hard physical work or high temperatures. Tests performed according to ASTM E96/E96M.

The filtering facepieces in this series are tested against nanoparticles (down to 0.001 microns).

Individual hygienic packaging protects the dust mask from contamination before use, ensuring convenient storage and distribution in the work environment.
