Self rescuer portable oxygen respirator
We research and produce oxygen and air breathing apparatus from the year of 1989, has more than
25 years experience in this field.
This respirator comply with standard GA632-2006. Suitable for use in long-term toxic and harmful
environment. It can also be used for fire protection, petroleum, chemical, metallurgical underground
engineering departments, specially trained personnel in the toxic and harmful gas in the environment.
The whole set include the mask for the exhaust hose , high pressure oxygen cylinders, pressure
relief devices , gas chamber , special agents and protective containers.
