 HFZY30 fire home security Industrial Co., Ltd. in Shanghai to provide you with filter self respirators, personal protective equipment to prevent toxic gases into respiratory tract, the product in accordance with national standards to design and manufacture and testing of GA209-1999, the technical indicators are in line with national requirements. 
 Protection are: military agents: such as sarin, hydrogen cyanide, hydrogen chloride, arsine, phosgene, pairs of light gas, chloropicrin, lewisite gas, mustard gas and other common precursor gas: such as chemical organic gases and vapors : benzene, acetone, alcohols, aniline, carbon disulfide, carbon tetrachloride, dioxane methane, methyl bromide, methyl chloride, nitro compounds, etc.; ammonia, amines and organic amine derivatives, etc.; acidic gases and vapors: sulfur dioxide, hydrogen chloride, chlorine, hydrogen sulfide, oxides of nitrogen, phosphorus and chlorine organic pesticides. Carbon monoxide in the scene. Harmful aerosols; such as radioactive aerosols and bacterial aerosols, toxic smoke, smog, etc.. Performance characteristics; fire filter self respirator full face mask and canisters. Pairs of back to hem seal structure, full face mask suitable for a variety of different shape and size of the head, wear comfortable, has a very good seal. Headband with five soft rubber, head buckle composition, good elasticity, the tensioning moderate, reliable locking fully cover the windows of big eyes and lenses made from polycarbonate, a special surface treatment, with a broad perspective, a good optical performance, wear impact resistant intercom combination with good call performance, and reasonable arrangement of the inspiratory and expiratory valves, a suitable suction and exhaust system. Canister with full face mask connected fast and convenient, reliable air-tightness of the junction. Canister out of the pores with soft rubber seals, seal long-term, to ensure that the same performance of the products within the validity period. Mask and canister connecting thread interface complies with EN148-1 and EN136 standard, suitable for connection to the canister of the domestic variety of joints. Main technical parameters:
