Thread: Oxygen concentrator power requirements.

  1. #1

    Default Oxygen concentrator power requirements.

    I just un-plugged my father's oxygen concentrator from the Kill-O-Watt. 4.42 kwh for a 12 hour period. The thing runs 24/7 so 8.82 for a 24 hour period. So far in searching the internet for specifications I have found that manufacturers don't advertise much in the way of power requirements. Hoping someone on the forum may have already researched this topic, and could provide some guidance.

    What sort of guidance? One that doesn't use such a whopping amount of power? That would be nice. That really is a lot of power use daily; no wonder they don't want to talk about it.

    Wow, that's a pretty heavy consumption, roughly 370 watts continuous. That's major for an off grid system. Over 8.8 Kwh/24 hours, that's enough to power perhaps 9 new full size Energy Star fridges! That sucks!

    Since the units are basically air compressors you can see why it would be a big power user. Hard to compress any significant volume of air without using a lot of power, and then having to run it all the time ...

    I wonder if any supplier of these would mind if you brought along the Kill-A-Watt and measured a few in operation? If they were smart they'd see it as a selling feature; "this one uses the least energy for the volume of oxygen produced".

    Interesting info on how it works. Looks like considering what it does/how it operates, perhaps it's no wonder it sucks back on the power.

    There are some portable units out there. This thing is a dinosaur, and a rental at that. Maybe there has been some progress. I'll call up some medical supply stores and see if they have some info.

    Yeah. It has a compressor that doesn't ever shut down.

    CPAP's are tiny compared to O2 concentrators. No comparison at all, other than they both move air somewhat.

    you haven't mentioned what you have in mind with this info. are you on grid and just want backup power for it in case of an outage and if so then for how long? if you are looking at off the grid then as was said this is a huge draw of power constantly running and could compromise an offgrid pv system from supplying enough power for that and other items if not accounted for in the initial design.
