1- or 2-person electronic digital pulse demand aviation oxygen delivery system Saving of cost and place for two-seaters.

Mountain High Oxygen is pleased to announce the release of our next generation of EDS (Electronic Delivery System) Pulse Demand oxygen controllers, the O2D1-2G and O2D2-2G.

The EDS unit now incorporates a MIL spec ruggedized easy-to-grip rotary control switch providing improved reliability, increased ease of function and visibility. This switch also has very positive position detents for excellent tactile feedback making it resistant to changes from causal rubbing or bumping.

While we were at it, we improved the manifold design to allow for better breathing response and effort tracking. This combined with a new circuit board, as well as a new micro-controller, gives improved power-conserving operations with even less RFI emissions, better respire-metric tracking and dispensing of oxygen in finer resolution resulting in smoother steps from altitude and breathing changes.

Other improvements include a dedicated bi-color system battery status light allowing much easier monitoring and definitive indication of battery condition without being confused as a station operation. The original O2Dx units encoded the low battery notification into the station lights. This status light also responds to each control switch change with a beep and green flash to confirm your actions. Also the audio alerts and warnings are louder, more crisp and dynamic to human hearing in an effort of being heard over modest cabin noise. The O2D2 has a 600 Ohm stereo external audio jack as well as a USB compatible (5VDC) external power port.

More intuitive F-Mode settings labeled as 1, 2, 3 & 4 for use with face masks or when more oxygen is required.

Abandoned unit auto shut off: If you should forget to turn your EDS off after use, it will now go into auto shut-down (drawing very little power) after 3 hours of detecting no use in an attempt to save the batteries for another flight.

Scope of delivery

• EDS02D2 unit
• 2 ea. face masks
• 2 ea. breathing cannulas
• 2 ea. carry bags
• cannulas
• reducing regulator DIN 477 or CGA (optional)

Note: Pressure Regulator Required for EDS System

To operate the EDS system, a pressure regulator is required for connection to the oxygen cylinder. Different versions are available depending on the region and cylinder type:

• DIN fitting (Europe)

• CGA fitting (USA)

DIN Pressure Regulator Variants

The DIN regulator is available in several configurations:

• With pressure gauge (standard):
  Displays the cylinder pressure, allowing easy monitoring of the oxygen level.

• Without pressure gauge:
  Only recommended where space is extremely limited, as it does not indicate the remaining contents of the cylinder.

New: Two-Stage DIN Regulator

This updated model allows you to use the oxygen down to approximately 10 psi (about 1 bar) above the set delivery pressure. This allows the contents of the bottle to be used more efficiently - particularly advantageous for two-seaters with 2-litre bottles.
