The portable oxygen Cylinder – DE Series is a therapeutic Oxygen Conserving System designed for passengers who have a pre-existing medical condition and pre-book oxygen for their flight(s). The advantage of Pulse Dose is that oxygen is only consumed during the inhalation part, resulting in volume savings.
The DE series has 5 pulse settings with constant flow settings of 2-4 liters per minute. The system includes a lightweight DOT approved cylinder, available in 3 sizes: 2.0, 2.7 and 3.2 liter with a working pressure of 200 bar.
The conserver gives extremely economical performances, releasing a bolus of oxygen as soon as it registers a small drop of pressure in the passenger's nose. It then closes very quickly, thus conserving oxygen. The regulator is of a robust design and incorporates a number of safety features. The 'cage' is manufactured in a flame retardant material and is designed to protect the regulator and conserver and to facilitate the handling of the oxygen cylinder.
A bag designed with flame retardant material includes operating instructions, a cannula, a mask and loops for attachment. Cannula assemblies can be supplied with an inline flow indicator, allowing cabin crew to check delivery of oxygen without disturbing the passengers.
