The Cobham PHANTOM Jump Bottle System represents the next generation of parachutist oxygen equipment. When combined with the new PHANTOM mask and regulator assembly, part number B47300 series, the new system is a breakthrough in comfort and performance. The PHANTOM Jump Bottle System uses state-of-the-art material technology to provide significantly increased oxygen supply durations while reducing the overall weight of the system. The system consists of a lightweight carbon fiber full composite (CFFC) oxygen cylinder and pressure reducer assembly. When filled to 3,000 PSIG, it provides 410 liters of breathable oxygen, 45% more than comparable systems. The system is supplied with a 39-inch, small-diameter flexible hose which can connect to either the PHANTOM or other mask systems. The new hose has a smaller diameter than previous systems. This minimizes interference with jump equipment and offers greater mobility. Additionally, the PHANTOM jump bottle can be used by aircrew as a portable or walk-around oxygen bottle.
