Isolated Chemical Oxygen Regeneration Self Rescuer for Underground Coal Mine

Introduction Of

ZH Chemical oxygen self-rescuer  is a self-rescuer that generates oxygen through a chemical reaction. None reusable. Mainly used in coal mines or ambient air pollution and toxic gases occurring hypoxic choking hazard, the site quickly worn to protect people fleeing the disaster area normal breathing.
Oxygen generating process main reaction equation is: 
The chemical oxygen self-rescuer is a personal respiratory protection device designed using the principle of chemical oxygen. The respiratory protector is isolated from the outside air. The breathing method is reciprocating and the use is not restricted by the surrounding toxic gases.
          2KO2+H2O→2KOH+1.5 O2+heat
          2KOH+CO2→K2CO3+H2O+heat

ZH45 Oxygen self-rescuer
Principle of operation:
The ZH45 also uses chemical oxygen generation technology and works on a similar principle to the ZH30, providing a complete oxygen supply through a chemical reaction.
Key Features:
Oxygen supply: approximately 45 liters of oxygen is available, suitable for short to medium time escapes;
Easy to use: easy operation steps, convenient and quick to wear;
Medium weight: makes it more convenient to carry.
Applicable scenes:
Mining operations, chemical plants, firefighting and other occasions that require emergency breathing.
