PHAOS - Parachutist's High Altitude Oxygen Supply System

The PHAOS (Parachutist's High Altitude Altitude Oxygen Supply) System is deigned to meet the high altitude parachutist's mission requirements. The PHAOS System integrates an MBU-12P mask with an automatic diluter/demand regulator (as opposed to a constant flow system). This maximizes the effective use of oxygen which is consistent with mission objectives and individual user requirements. The PHAOS system provides automatic 100% oxygen breathing when connected to a pre-breathing oxygen console and programmed dilution when breathing from the individual oxygen supply. This system was developed by integrating component concepts tested to military specifications. The PHAOS System is compatible with current oxygen systems and pre-breathing oxygen consoles. This system has a 35,000 foot capability.

The PHAOS Oxygen Supply
    The individual oxygen supply manifolds a reducer, on/off valve, relief valve, gauge, fill valve, oxygen console connection, bottle(s) and hose assembly. The reducer provides strict control of the oxygen supply. The on/off valve is human engineered for parachutist's safety. It must be turned to the "on" position before connection to the pre-breathing oxygen console. When disconnected from the console, the individual oxygen supply automatically flows. The hose assembly includes a quick disconnect fitting.

The PHAOS Mask
    The low profile, lightweight mask incorporates a diluter/demand regulator, auto dilution shut off, dilution aneroid, exhalation valve and male bayonet fittings. The mask eliminates hoses and connectors on the front torso providing the parachutist with a "clean front" thus improving vision and mobility. The mask mounted dilution port and exhalation valve allows the user to breathe comfortably throughout total descent, even after all oxygen is consumed. This also provides facial protection for inadvertent landings in brush and trees.

PHAOS Optional Equipment
    The basic PHAOS System can incorporate: Various bottle capacities to increase duration. Light weight bottles. Mask integrated communications (microphone). Helmet with fiberglass hard shell, rigid foam insert and bayonet receptacles. Helmet integrated communications (headphone).
    All optional equipment is interchangeable with existing equipment and conforms with relevant military specifications.
