Oxygen Products oxygen self rescuer protection according to the time 15 minutes, 30 minutes, 45 minutes, 60 minutes several. Compressed oxygen self-rescuer can be recycled, other self-help can not be recycled, greatly reducing the cost. Oxygen self-rescuer is mainly used to work in ambient air pollution and toxic gases occurred during hypoxia, provide the wearer with clean oxygen. Features: a, with a dual-circuit breathing cycle, ie breathing each unidirectional channel, compared with reciprocating breathing, the advantage of low resistance, no dust inhalation, not choking, suction temperature is low, comfortable, safe and reliable. b, Oxygen has three ways: quantitative oxygen, oxygen supply automatic and manual oxygen supply. Greatly improving the safety and reliability of respiratory protection. c, filled with oxygen absorber replacement, easy maintenance and repair. d, long time protection, ease of self-help. e, small size, light weight, easy to carry. f, can be used repeatedly, the use of low cost. g, pressure indicators were observed to close, easy to use. The operating principle of oxygen self rescuer use, turn the cylinder valve, high pressure oxygen from an oxygen bottle pressure through the valve to ≥1.2L / min into the balloon, hands off qi nourishing plate stops. When the respiratory system is negative, the qi plate inward contraction, oppression qi qi mechanism lever to open the oxygen to ≥60L / min into the airbag when the airbag inflates, leaving qi qi plate rod, qi Stop. If the air pressure within the respiratory system pressure exceeds the exhaust valve exhaust gases from the exhaust valve overflow. Inhale, airbag oxygen into the body through the oral appliance. Exhale, exhale through the hose into the clean gas tank, gas carbon dioxide chant placed in clean absorbent to absorb CO2 tank, the rest of the gas into the air bag, according to the respiratory cycle. Oxygen self-rescuer technical parameters and characteristics of the guard time: time of 45 minutes (moderate labor intensity) Oxygenation: Quantitative oxygen:> 1.2L / min (L / min) gas storage capacity:> 76L (liters) Product Quality (including CO2 and oxygen absorbers): 2.1kg automatic replenishment of oxygen:> 60L / min (l / min) Manual oxygen supply:> 60L / min (l / min) Rated pressure: 20Mpa (200 kg) of auto exhaust pressure: 150-300pa (Pa) pressure safety valve Kai: ≤1Mpa CO2 absorbents should be installed capacity: ≥530g Dimensions: 227mmX177mmX96mm oxygen bottles: Volume: 0.38L (l) shenhua02 due to production batches, depending on the model, the above picture only For reference, the details you can contact our sales staff specific verification.
