How Chemical Oxygen Self Rescuer Works

Chemical Oxygen Self Rescuer protection device, respiratory protector, isolated from the outside air, reciprocating breathing, use is not restricted by toxic gases in the surrounding environment. When the wearer exhales, exhales through the mouthpiece, breathing hose, and the cooling net enters the oxygen tank. The water vapor and carbon dioxide in the exhalation react with the oxygen generating agent to generate oxygen into the airbag; when inhaling, the oxygen stored in the airbag is re-inhaled. After the oxygen generating agent, the breathing hose, the mouthpiece, and the cooling net from the oxygen generating tank are cooled into the human body to complete a breathing cycle. When the oxygen generated by the oxygen generating agent exceeds the oxygen consumption of the human body, the pressure inside the airbag gradually increases. When the exhaust pressure of the exhaust valve is reached, the exhaust valve on the airbag of the self-rescuer is automatically opened to discharge excess gas, and the pressure inside the airbag is less than The exhaust valve automatically closes when the pressure is exhausted.
