Serves Oxygen As Needed, Not At Constant Rate
Building on its leadership in general aviation oxygen systems,
Alice Baty and Linda Joppien of Mountain High’s aviation
oxygen technology for general aviation and rotorcraft have built
number 3000 (3000) of the two-person MH EDS O2D2 Pulse-Demand FADOC
(Full Authority Digital Oxygen Control) Oxygen Delivery Unit. The
MH EDS O2D2, designed and manufactured in Oregon, is the only
single unit, portable, two-place, digital Pulse-Demand oxygen
system available and is used through-out world by experienced
pilots, both civilian and military.
The MH O2D2, with the patented digital electronic Pulse -Demand
FADOC oxygen delivery system was tested by CAMI (FAA Civil
Aerospace Medical Institute). The MH O2D2 enables the pilot and
passengers to fly at pressure altitudes up to 25,000 feet with
absolute oxygen safety and comfort. The O2D2 digital pulse-demand
system reduces oxygen consumption dramatically. Different from the
“standard” constant flow systems, the O2D2 pulse demand
system wastes no oxygen during the breathing cycle. The average
user will enjoy a conservative consumption drop of four (4) times
or more compared to the manual constant flow systems. The system
operates, with one or two people, for up to 50 + hours on three AA
alkaline batteries.
Easy to use, the two-person O2D2 reduces oxygen system workload
to almost nil. There are no oxygen flow indicators to watch or
manually operated constant flow valves to adjust due to altitude
changes. The O2D2, through the various modes, automatically
delivers the required oxygen pulses for changing altitudes…
for both the pilot and passenger or with an additional O2D2, two
additional passengers. MH EDS O2D2 is a fully functional portable
system. The portable system consists of an aluminum oxygen cylinder
(buyer has a choice of sizes), a cylinder carry case, seat back
holding straps, primary reducing regulator, low pressure service
line, all connection fittings, the MH EDS O2D2 FADOC unit,
breathing cannulas, face masks, batteries and a tote
bag…everything needed for a complete supplementary oxygen
system, including a limited warranty.
A variety of options are available to meet specific pilot needs,
including lightweight composite cylinders, four place regulators,
adapters, Oxy-Arm boom cannulas and comfortable silicon facemasks
with built in noise cancelling ClearSpeak microphones.
