AMOUR P2 CLASSIC CUPPED PARTICULATE RESPIRATOR MASK VALVE CARBON | 12 PACK Metal free disposable respirator with silicon exhalation valve that resists dust while providing ease of breathing for extra comfort while working without risk of contamination. Low breathing resistance and high filtration efficiency. Loaded polypropylene material without any irritating or stimulant material. Double elastic straps moulded to mask. Adjustable nosepiece and inner foam provide a custom seal for different facial sizes. Tested and certified to AS/NZS 1716:2012 Additional active carbon filter layer to resist acid vapours, such as H2S, SO2, H2, N2 and micro dust Special 4-Ply pleated design, high filtration and static electricity material. What is a P2 Rating? P2 is a respiratory filter rating under the AS/NZS1716 standards for use in Australia and New Zealand. Protects against mechanically and thermally generated particles. Filtration rate: Filters at least 94% of airborne particles Suitable for: Relatively small particles generated by mechanical processes eg. grinding, cutting, sanding, drilling & sawing Sub-micron thermally generated particles e.g. metal & welding fumes, fertilizer and bushfire smoke, diesel exhaust & smoke and acid gases Biologically active airborne particles under specified infection control applications e.g. viruses, bacteria, COVID-19, SARS, bioaerosols & fungus Often distinguished with blue head straps What is the function of valves on disposable respirators? P1 and P2 respirators are available with a valve, either on the front or side. The purpose of respirator valves is to make exhaling (i.e. breathing out) easier, and reducing fogging to glasses and other eye/face protective devices causes by warm breath releasing from the sides of respirator. These valves are one way, allowing air to escape only when exhaling. This valve does not increase or reduce the filtration rating of a respirator. For example, a P2 mask with a valve does not offer higher protection than a P2 mask without a valve.
