Product Description 

 ZY45 isolated compressed oxygen self-rescuer is the use of compressed oxygen gas source for the isolation closed-circuit loop personal respiratory protection devices, mainly used for the occurrence of toxic and harmful gas pollution and lack of oxygen in the air of the working environment and provide clean oxygen to the wearer. 

 Performance characteristics of 

 The use of the self-rescuer, the counterclockwise rotation of the cylinder valves, high-pressure oxygen from the oxygen cylinder through a vacuum valve to ≥ 1.2L/min enter airbags, hands off the the qi plate nourishing stop. When the respiratory system for negative pressure, air entrainment plate inward contraction, oppression qi lever to open the qi institutions oxygen ≥ 60L/min filled airbags when airbags muster the qi plate left the qi rod, qi stop. If the air pressure within the respiratory system than the exhaust valve exhaust pressure, the gases from the exhaust valve overflow. As you inhale, the air bag in the oxygen enter the body through the mouth with. Exhale, the gases pass through the breath hose into the clean tank, the gas carbon dioxide in the chant placed in the clean tank of CO2 absorbent absorption, the remaining gas into the airbag, according to a respiratory cycle.
