Description
The MH EDS two-person O2D2 with the patented digital electronic Pulse-Demand™ oxygen delivery system enables general aviation and
sailplane pilots and passengers to fly at pressure altitudes up to 25,000 feet with safety and comfort. The EDS Pulse-Demand™ technology
is different from the ‘standard’ constant flow systems, the O2D2 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 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 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, the two-person O2D2 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 through the various modes that automatically deliver the required supplemental oxygen pulses for both the pilot and passenger. The EDS O2D2 unit measures 4.3 x 3.85 x 1.25 inches and weighs 12.1 oz (343g) with batteries.
The standard EDS O2D2 is a two-person outlet system. Two EDS O2D2 units may be combined for a four-place system such as would be used in a four-seat aircraft (pilot & co-pilot using one O2D2 system in the cockpit; two passengers using a second O2D2 system in the rear – all taking oxygen from one centrally located cylinder).
A single system consists of a two-person EDS O2D2 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.
