KEYFUN Mf1a Russian Full Face Gas Masks:

* KF-GM4001 is made of high quality natural rubber with higher protection level and no harmful substances.
* Oil production, chemical production, mining, fire rescue, epidemic prevention, metallurgical production, pesticide spraying,
painting and decoration, a large number of toxic gases, vapors from the medical experiments and so on. Long-term exposure will
cause respiratory tract, lung, heart, blood diseases and other various diseases , and even induce the carcinogenesis possibility.


Gas Mask (Former Type 4001 Gas Mask):
The gas mask is composed of a mask and a gas tube (or filter element) of Canister . The mask includes a cover, an eye window, a telephone, a breathing valve, a headband (or helmet) and other components.
The Canister is used to purify toxic gases. It contains a filter layer and adsorbent. The two materials can also be mixed into a filter plate and assembled into a filter element. The lighter filter tank or filter element can be directly connected to the mask, and the heavier filter tank can be connected to the mask through the air duct.
Filter gas mask is one of the most common types of gas mask. The filter gas mask mainly consists of two parts: the main body of the mask and the filter parts. The mask can seal and isolate the external air and protect the mouth, nose and face. Activated carbon with active carbon as the main component is filled in the inner part of the filter. Because there are many different shapes and sizes of pore in activated carbon, it can adsorb dust. On the pore surface of activated carbon, chemical agents such as copper, silver and chromium metal oxides are impregnated, so as to react with the adsorbed toxic gas and make the toxic gas lose its toxicity. The new active carbon agent uses molecular-level coating technology, which can make the thickness of impregnated drug uniformly adhere to the effective micropore of carrier activated carbon, and make the antivirus agent impregnated into the effective micropore of activated carbon have the best quality performance ratio. Anti-poison charcoal is used to protect poison vapor in filter gas mask. Anti-toxic charcoal is made from activated carbon. Activated carbon is made by impregnating the porous surface of activated carbon with chemical agents such as copper, silver and chromium oxides of filtered gas mask.
The functions of poisons are as follows: 1. physical adsorption of capillaries; 2. chemical changes of reactions between chemicals on carbon and poisons; 3. oxygen and water in air react with poisons under the catalysis of chemicals on carbon.
