An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
While E-SAPI plates do hold significant defensive advantages over the preceding SAPI plates, the increased protection comes at the cost of increased weight and significantly increased cost. Comparing medium-sized plates, a SAPI plate weighs 1.82 kg (4.0 lb) while an E-SAPI plate weighs 2.5 kg (5.5 lb), over a 35 percent increase in weight. [ 15 ]
