ZH*0/ZH*5 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
ZH*0/ZH*5 is oxygen candle born oxygen in early. After
opening air sac quickly, utilize air pressure combine with
CO2and water
vapor, through chemistry , made into O2for people to breathing. This
pure oxygen take shape closed-circuit circulation system through
air sac, cooling nets, orifice plate etc, for people to
breathe.
