Isolated compressed oxygen self-rescuer

1.   Scope of application

The personal respiratory protection devices is suitable for escape when gas explosions, fires and gas outbursts occurring in coal mines which cause the lack of oxygen, or the emergence of harmful gases that endanger the lives of miners.

2.   The main technical parameters

3.   working principle

Inhaling the oxygen in the airbag directly after turning on the switch. The exhaled gas can be breathed again after purified through the cleaning tank,absorbed and supplemented with a certain amount of oxygen. It completes protection in thus way.The product adopts three oxygen supply modes: quantitative, manual replenishment and automatic replenishment. Turn the switch counterclockwise and the high-pressure oxygen will automatically output to the airbag after decompression. Press the pressure plate to make up oxygen entering the airbag at 60 L/min. It stops when leaving off the pressure plate. When the respiratory system is under negative pressure (the air bag is deflated), the pressure plate presses the supplementary air needle to open the oxygen supplement mechanism, and oxygen is filled into the airbag at 60 L/min. When the airbag is inflated, the supplementary air pressure plate leaves and the supplementation stops .
