4279 该呼吸器可防止有机蒸汽、无机、酸性气体和氨气浓度达到 10 ´ 4 点式束带调整可确保最大的舒适度和最小的压力 整合过滤器 标准 符合 EN 405:2002 FFABEK1P3 的要求 3M，半面罩
The from is a half mask gas and vapour respirator. The 3M 4279 provides protection against organic vapours boiling above 65°, inorganic and acid gases and ammonia, up to 10 times OEL or 1000ppm whichever is lower. 10 times OEL for particulates. This uses twin inhalation valves to reduce breathing resistance, together with bonded carbon filters which do not require granule containers. This is complemented with a parabolic valve which further reduces breathing resistance whilst preventing heat build up. The single piece integral construction also avoids operator assembly errors and allows a respirator to be designated to a specific area, making a respirator programme easier to manage.
