5: Back Plate Assembly with Harness
6: Steel Air Cylinder
Air is compressed in the cylinder (pressure of 20 MPa) . Compressed air is reduced to (0.75±0.15)MPa through the pressure reducer, and led to medium pressure hose . Then it is reduced pressureagain through the demand valve and provided to user through full face mask .The outside toxic gas or particles can not get inside because the pressure inside the mask is alwayshigher than the atmospheric pressure .Thus the tightness of the face mask is guaranteed .
