ZH Series Isolated Chemical Oxygen Self Rescuer Introduction
ZH Series Isolated Chemical Oxygen Self Rescuer is an isolated
closed circuit breathing apparatus.
Mainly used in coal mines or ambient air pollution and toxic gases
occurring hypoxic choking hazard, the site quickly worn to protect
people fleeing the disaster area normal breathing.
chemical oxygen self-rescuer respiratory protection for the
respiratory gas reciprocating,
using KO2 flaky oxygen oxygen enerating agent, candles starter.
Breath by mouth with oxygen bottles of medicine into the raw
produce oxygen absorb carbon dioxide, oxygen-containing gas into
the airbag. Inhale, airbag gas purification by re-entering the
mouth with bottles of medicine, oral inhalation,
because oxygen generating agent in oxygen uptake than raw speed of
the body consumes oxygen, respiratory protection when the gas is
greater than the exhaust valve opening pressure, exhaust
automatically open the exhaust valve, lower than the exhaust
pressure, exhaust valve automatically shut down to protect the
respiratory isolation with the outside atmosphere.
Oxygen generating process main reaction equation is:

other models available; ZYX-30,ZYX-45,ZYX60,ZL60 etc.
