The overall performance of the previous Army volume-cycled respirator models was satisfactory however, the flow consumption 61 lambdamin was determined to be undesirably high. The Model 4 volume-cycled respirator was designed to reduce the required amount of flow while retaining the functions volume- and pressure-cycling capabilities, assist and control of the previous models by using low-power flueric components and combining the patient and power circuits. The maximum flow consumption of a breadboard model of this respirator was 21 percent of that required by the previous models, and general performance of this respirator exceeds that of the previous models.
