Turn the switch handwheel counterclockwise to supply oxygen. High-pressure oxygen flows from the oxygen cylinder to the pressure reducer. After decompression, the automatically output oxygen enters the air bag. To activate the air supply and oxygen supply, press the air supply pressure plate with your finger, and oxygen will enter the air bag. If your finger leaves the air supply pressure plate, the oxygen supply will stop.
Automatic air supply and oxygen supply When the respiratory system is under negative pressure, the air supply pressure plate contracts inward, pressing the air supply rod to open the oxygen supply mechanism, and oxygen enters the air bag. When the air bag inflates rapidly, the air supply pressure plate leaves the air supply system. Air rod, air supply stops.
When inhaling, oxygen enters the human body from the air bag, breathing valve, and mouthpiece. When exhaling, the gas enters the clean tank through the breathing valve and exhalation hose. The exhaled gas is absorbed by the absorbent in the clean tank, and the remaining oxygen enters the air bag and mixes with the oxygen output from the pressure reducer. This repeats to complete the human breathing cycle.

Compressed oxygen self-rescuers are portable and are mainly used in mines, firefighting or other environments. When toxic gas pollution or hypoxia suffocation disasters occur in the air, they are provided to on-site personnel to wear them in time to protect personnel from breathing normally and escaping from the disaster area
