mine disaster oxygen self-rescuer

Product Introduction

features:

1.This product is a kind of isolated closed-circuit cycling breathing apparatus
2.Adopt cycling breathing method
3.Have 3 oxygen supply methods
4.Advanced pressure reducing principle, with features such as small volume, light and stable performance etc.

Working principle:
1.Rated oxygen supply: turn the handwheel of switch in direction of counter-clockwise, high pressure oxygen flows into reducer from oxygen cylinder, automatically input 1.2L/min oxygen into air bag after reducing pressure.
2.Manual oxygen supply: press air supply binder plate with finger, oxygen enters air bag at the speed of 60L/min, fingers leave air supply binder plate, stop supplying oxygen.
3.Automatic oxygen supply: when breathing system is at negative pressure, air supply binder plate shrinks inward, forcing air supply pole to open oxygen supply organ, oxygen enters air bag at the speed of 60L/min. When air bag plumps up rapidly, air supply binder plate leaves air supply pole and stops supplying air.
4.Oxygen enters human body through air bag, breathing valve and gauge while inhaling. Air enters clear can through breathing valve and breathing soft tube while breathing. The CO2 that human body breathes is absorbed by the absorbent inside clear can. The remaining oxygen enters air bag and mixes with the oxygen output by reducer. Finish human’s breathing cycle by doing this again and again.
