Helium Oxygen Blender
It is the only freestanding pneumatic HeliO2 blending device on the market today. The ability to turn the bleed control collar ON or OFF provides ± 3% FIO2 accuracy as well as quieter operation and maximal heliox tank durations.
The tough housing makes the unit durable and the selection control knob is recessed to prevent inadvertent changes in FIO2. The modular design can reduce maintenance time and costs. The unit can be easily maintained by all biomed departments.
The unit is available in four models, High-Flow 80/20 or 70/30 and Low-Flow 80/20 or 70/30. When paired with the optional cylinder clamp and pole, clinician setup time is greatly reduced and tank changes are easy. Multiple accessories can conform to clinician and user needs.

Pressure Drop
| Low Flow: ≤ 2 psi (0.14 bar)at inlet pressures from 30 - 90 psi (2.1 - 6.2 bar) and at 10 L/min flow rate at 60% FI02. |
| High Flow: ≤ 3 psi (0.14 bar)at inlet pressures from 30 - 90 psi (2.1 - 6.2 bar) and at 10 L/min flow rate at 60% FI02. |
Pressure Drop Additional Info
| The Helium - Oxygen Blender has been cleaned for Oxygen Service prior to delivery. |
| The Helium - Oxygen Blender reverse gas flow complies with clause 6 of ISO 11195. |
| The Oxygen Analyzer should comply with ISO 21647. |
Dryness and Composition for inlet gases
| Heliox: Medical grade 80/20 or 70/30 required. |
| Oxygen: Oxygen supply must meet all requirements of USP Medical Grade Oxygen. |
| Dew Point (ONLY for CE requirements: Both inlets should remain 10°F (5.55°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/cm2) this equates to 2000 mg/m3. |
| Accuracy of FI0² will be affected if bleed flow is not engaged at low flows. (At or below 3 L/min for Low Flow and 15 L/min for High Flow). |
| When Heliox tank pressure and oxygen outlet pressures are unbalanced, bleed may need to be engaged at a higher liter flow to maintain accuracy. |
