This product is a self-contained compressed-air-operated
breathing apparatus. The high-pressure air is depressurized by a pressure-reducer and then
transported to the supply valve through a median-pressure pipe.
The supply valve and face mask is
connected and when the wearer respires, the supply valve will output adequate air to the wearer
according the respiratory demand. And when the wearer exhales, the supply valve stops to output the
air and the expiratory air will be released to the air through the expiratoiy valve in the full
face mask.
During the cycle process of respiration and expiration, the air always flows into the
same direction because of the control of the respiratory valve and releasing valve. And in the
whole process, the pressure inside the face mask remains larger than that of the outside air so
that the wearer's safety can be guaranteed.
The self-contained compressed-air-operated breathing apparatus self-contained composed by cylinder valve, pressure reducer,quick connector, supply valve,the face mask,air pressure gauges,cylinder residual gas alarm,back care, straps, belts ,etc. Structure of respirator
Using wingding type carbon fiber composite cylinders.Different cylinders with different volumes are
provided, such as 5L,6L and 6.8L, whose rated working pressure is 30Mpa. As the shell of carbon
fiber composite cylinder is formed with the winding of carbon fiber, scratches, which will induce
break of the carbon fiber, should be avoided when it is used. Once any scratch is found, the
cylinder should be stopped to be used immediately. Check its valid date of the cylinder before
using cylinder and it is forbidden to use it on expiry. Cylinder’ s hydrostatic test must be taken
every three years,and the test
