FIO2 Accuracy:*
± 3% of full scale @ 50 psi (3.4 bar)
Pressure Drop:
Low Flow:
≤ 2 psi (0.14 bar) at inlet pressures from 30-90 psi
(2.1- 6.2 bar) and at 10 lpm ow rate at 60% F
IO2.
High Flow:
≤ 3 psi (0.21 bar) at inlet pressures from 30-90 psi
(2.1- 6.2 bar) and at 30 lpm ow rate at 60% F
IO2.
The Helium-Oxygen Blender has been cleaned for Oxygen Service prior to delivery.
The Helium-Oxygen Blender reverse gas ow complies with clause 6 of ISO 11195.
The alarmed Oxygen Monitor / Analyzer should comply with ISO 7767 to
meet CE requirement.
Dryness and Composition for inlet gases:
Heliox:
Medical grade 80/20 or 70/30 is required.
Oxygen:
Oxygen supply must meet all requirements of USP
Medical Oxygen.
Dew Point:
(ONLY for CE
requirements)
Both inlets should remain 10°F (-12.2°C) or more
below the lowest temperature to which the air
distribution system equipment is exposed. At a
temperature of 25°F (-3.9°C) and a pressure of
90 psi (6.33 kg/cm

will be affected if bleed ow is not engaged at low ows. (At or below 3 lpm for Low Flow and 15 lpm for High Flow)
.
* When Heliox tank pressure and oxygen outlet pressures are unbalanced, bleed may need to be engaged at a higher liter ow
to maintain accuracy.
