Detailed Description

Feature When open the oxygen tanks, high pressure gas by pressure reducer into medium pressure gas. Medium pressure gas all the way through the demand valve, and the other all the way through quantitative gas hole into the low pressure in the system With the increase of the human body the intensity of labor, when the pressure in the air to demand open valve, the valve spring clamp contact demand, demand valve open, the medium pressure gas inside air oxygen filling via the demand valve to meet human demand for oxygen Airbags within the low pressure gas by suction cooling device, the suction, suction valve to the mask, man in a mask breath exhale through the exhalation valve, pipe, clean cans to the balloon Parameter Nominal protection time :240 min Oxygen bomb rated working pressure :20 MPa Oxygen tank volume :2.4L Oxygen capacity :440L respiratory capacity :30L/min exhalation resistance :≤600Pa inhalation resistance: (0-600)Pa Oxygen supply ration :(1.4~1.7)L/min Automatic oxygen supply ration: ≥80L/min Manual oxygen supply ration :≥80L/min Dimension :560×370×160mm Weight :13kg
