1.Product Features
ZH30/ZH15 self-rescuer is a equipment whom work under the well. Provide the workers for fresh air whom under the well when take place catastrophe and cause poisonous gas or hypoxia (gas blasting, coal and gas blasting, fire etc). This is a personal protective apparatus for breathing system which can generate oxygen in an isolated close cycle by chemical reacting, and be used to provide the wearer with oxygen when exploring a coal mine or in the environment where toxic gases exist or oxygen is deficient. Respirators apply to underground work, entertainment, fire disaster,
toxic gas environment, etc.
2.Structure and Principle
ZH30/ZH15 is oxygen candle born oxygen in early. After opening air sac quickly, utilize air pressure combine with CO2 and water vapor, through chemistry , made into O2 for people to breathing. This pure oxygen take shape closed-circuit circulation system through air sac, cooling nets, orifice plate etc, for people to breathe.
3.Main Performance
