via dei Giovi, 41 20032 Cormano (MI) - Italia t/f +39 0239310212 / 0266200473 [email protected] - www.blsgroup.com THREE-FLAP FLAT FILTERING FACEPIECES BLS Zer0 Flat series 3-flap filtering facepieces offer high protection combined with exceptional breathing comfort. They feature a surface micro net that prevents clogging of the filtering material and absorption of liquids, thus ensuring a longer life of the device. The facepiece provides the protection of a P3 with the breathability of a P1 and can be used for more than one work shift. ARMOR® EXTERNAL PROTECTIVE LAYER RIGID INNER CORE The outer protective layer surrounding the filter material protects it from dirt, dust and liquids, as well as the stress caused by prolonged use. The device performs for a longer period of time. The addition of an innovative inner core provides solidity to the filtering facepiece and high breathability, while maintaining low breathing resistance. AVAILABLE IN TWO SIZES This series is available in two different sizes, S and M/L, to perfectly fit all face profiles. Size S has been specially designed for female faces. -15% HIGH-EFFICIENCY EOLO VALVE An ultra-light membrane concentrates exhaled air in two maximum opening zones, 30% wider than standard valves, ensuring low breathing resistance and avoiding the risk of fogging up of spectacles. TEXTILE WELDED ELASTICS The elastic bands are made of enduring and high-performance textile material. The addition of a backing layer allows the elastics to adhere to the filter body without the use of exposed metal parts. INTERNAL NOSE CLIP 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.
