Isolated compressed oxygen self rescuer is mainly used in coal mine or environmental air pollution of poisonous gas and asphyxia hazards,field personnel quickly wear,the protection of human normal breathing to flee.coal mine workers in the event of gas outburst,fire and explosion disaster accident,as well as rescue workers in respiratory failure using rapid evacuation.
Self rescuer is mainly composed of the respiratory system and the CO2 filter system of high pressure system,consisting of high pressure system including oxygen bottles,oxygen bottle switch,pressure regulator,automatic and manual supply valve and pressure gauge.
Respiratory system consists of mouth,nose clip,breathing hose,air,exhaust valve and breathing valve.
