O2 booster working from 10 bar (150 psi) to 300 bar (4'500 psi), does it exist?

Please, please give me additional information! Please.

That's very interesting. Do you have a link or datasheet or more information? What is maintenance like on it? Is this a quality thing affordable because it's mass produced for medical use, or "crappy but good enough" pump from some generic chinese manufacturer?

I would love a Masterline electric booster but can't justify the cost vs. just going to the dive shop. It's fascinating to see something for 1/10th the price unless that was a typo.

Not really much information on it. It is based on the Ultrafill by philips. It is a discontinued model. Myself and a friend bought a semi trailer of them on liquidation for conversion to scuba application. They are new, but not warranted by the manufacturer due to modifications.
There isn't really any maintenance. Parts are available from Philips but their pricing is considerable. I have been using my personal one A LOT for the last two years and it hasn't had a hiccup yet. The orginal design was made to fill to 3000 psi from a concentrator input. I modified it to feed from a BC inflator hose and fill to a DIN output. I added high and low pressure cutout switches. The original temperature and burst disc safeties are still intact. I found I could go to 3200psi and stay within nameplate amp draw. That is why the 3200 cutout setting. They were designed and built for oxygen use. I use mine with helium and trimix more than oxygen due to its ability to pump down to 15 psi.
It isn't a masterline, it isn't even in the same league. It is 100 LPH, that is per hour, not minute. It is perfect for a home user wanting to fill tanks overnight. It is automated with high and low pressure cutouts. It is not something that would be useful in a shop environment. I was trying to fill a niche of home user looking for a good value and willing to give up speed for that.
Runs on 110V and while it isn't silent, you can barely hear it running.

Great!

Oh, it is 100 lt /hour, I was missreading 100 lt /min. But as you say it can run over night.

How much is amp consumption?
Does it work on 240V or do I have to change motor?
Do you have pics of compressor's inside?
Do you sell to Europe?

Lots of questions, I know

It is 110V. The motor is integral to the booster pump. I'm sure it could be changed, but everything else would need redone as well since the controls are also 110v. A step down transformer would be easier.
It uses between 70 and 90 watts depending on pressure, so less than one amp on 110v.
I do not, I have pictures inside the case, but not inside the booster itself, I haven't torn one apart.
I haven't, but I could, not sure what shipping would cost. They weigh 50 pounds and are fairly large.

Great, step down transformer sounds good, I will buy one.
Can you pleas send pics inside the case? This would be great.
What is size? Length, widht, hight? I am sure we will find a way for transportation.
