Precision Low Flow HeliO2 Blender


SKU: FOB 5480 Categories: ,


It’s Unique
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.

It’s Durable and Modular
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.

It’s Versatile and User-Friendly
The unit is available in two models, 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 patient needs.
