O2D2 Pulse-Demand™ Two Person Oxygen System

The MH EDS O2D2-2G with the patented digital electronic Pulse-Demand™ oxygen delivery system enables the general aviation and sailplane pilots and passengers to fly at pressure altitudes up to 25,000 feet with safety and comfort.

Highly Efficient: Delivers Oxygen Only When you Inhale

The EDS Pulse-Demand™ technology is different from the “standard” constant flow systems, the O2D2-2G Pulse-Demand™ system wastes no oxygen during the breathing cycle (exhaling and pausing before inhaling again) when oxygen is not being delivered to the lungs. The O2D2-2G digital Pulse-Demand™ system reduces oxygen consumption dramatically. The average user will enjoy a duration increase of two to three times compared to the constant flow systems. The system operates with two people for up to 100 hours on three ‘AA’ alkaline batteries. A low battery warning alerts the pilot that there are about three hours remaining. The O2D2-2G has an external power jack enabling it to be operated from an external power source. The external audio output alarms can be heard over the aircraft ICS.

Easy to Use: No Manual Adjustments Required During Flight

Easy to use, the Two-Person O2D2-2G with a built-in barometer reduces oxygen system workload to almost nil. There are no oxygen flow indicators to watch nor do you have to manually operate a flow valve, as you would with the constant flow system, due to altitude changes. A rotary switch cycles the O2D2-2G through the various modes that automatically deliver the required supplemental oxygen pulses for both the pilot and passenger. The EDS O2D2-2G unit measures 4.3 X 3.85 X 1.25 inches and weighs 12.1 oz. (343 g.) with batteries.

What’s In a System?

A complete system consists of an EDS O2D2-2G unit, oxygen cylinder, (buyer has a choice of low-cost aluminum or composite in a variety of sizes), a cylinder carry case, a seat harness, reducing regulator, connection tubing, fittings, 2 standard cannulas, 2 flare-tip cannulas, 2 face masks, three AA batteries, instruction manual and tote bags. (Note: cylinders are shipped empty). Systems picked up in person at MH will be filled with oxygen at no extra charge. If you already own a suitable cylinder, you can order the EDS O2D2-2G unit with any MH portable regulator.
