2. Working principle
The compressed air in the steel air cylinder of the THDF series urgent breath equipment goes throuth the pressure resucer, The reduced air goes out of the exit to be constant flow air, and then goes into mask through air supplying hose to provide the user with clean air for breathing.
5. Usage
1.Put the bag on the neck (or shoulder, or handle it by hand), and THDF before chest;
2. Open the bag, and take out the mask, and tear off the cover of the air cylinder valve, and then turn on the valve in anticlockwise till completely open;
3. Wear the mask on the head, and make the entrance of the air fit the face, and then fasten the belt;
4. Start to escape.
