Positive pressure oxygen breathing apparatus

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.
