Adjustable Oxygen Concentration Blender 21%-100% with Dual Output Ports

So you're setting up a respiratory system — maybe for a NICU, maybe for a transport setup — and you need something that isn't going to drift on you mid-shift. We've seen these used everywhere from neonatal incubators to heart-lung machine circuits, and dual output ports are pretty much the main reason buyers come back for more. You can run two separate devices simultaneously off one blender, which matters when you're tight on space or staffing.

It'll give you 21% to 100% oxygen concentration, and the pressure stabilization device inside is what keeps the flow consistent even if your source pressure fluctuates. We usually stock the GZ series with anodized oxidation on the surface — that's the medical-grade aluminum alloy — so it holds up to repeated cleaning without corrosion. One thing a lot of people don't think to ask is that it's ISO 13485 certified, which means it's built to medical device standards right from the factory.

That differential presure alarm with auto safety valve is not just a checkbox feature — it'll trigger if something goes wrong upstream, and it shuts down safely rather than dumping uncontrolled gas. You won't see a lot of other blenders in this price range carrying that feature as standerd. I'd say roughly 80% of orders come with the standard dual barbed fittings, but our company can accommodate quick-connects if you give us the spec.

Every unit ships with a certificte of analysis (COA) and the TDS that covers the pressure ranges — usually 30-90 psi input — though if you need an SDS for your facility's compliance binder, just mention it when you're ordering. dilevery times is about 20 days or so from order, give or take a few days depending on batch load. We've been handing these out to respiratory departments for years and the only complaint I've heard is that the alarm can be a little loud, which honestly is the point.

One thing you might not have considered is the dual output ports actually mean you can run a low-flow nasal cannula on one side and high-flow hood on the other, as long as your total demand stays within the blender's range. For most clinical setups we recommend the 5-60 LPM flow range as the sweet spot — better than trying to push 90 LPM through it for continuous ventilation. It's not suited for MRI environments though, just so you know; the aluminum alloy isn't ferromagnetic, but the internal valve components might cause interference.
