Chinese Boosters

[Tassi Devil Diver]

Does any one have any thoughts or experience with the Chinese boosters that are popping up around the place such as this double action model or this single action model

​

Am very interested to hear from people who are using or have some experience with them, the little I have been able to find so far indicates they are worthy of consideration and the price makes them very attractive.

I'm using this one:

Not Chinese, but Czech and a lot cheaper: USD 595

I'm not using it for oxygen, only for helium and occassionally air/nitrox when finishing a blend.
When emptying helium buffers, the booster runs a long time, using air from a D16 as drive gas. Since the used air is cooling the cilinders, the entire system stays at ambient temperature as long as you don't want to run it too fast. I manage to empty helium buffers down to 4 or 5 bar before sending them back. Gas loss: not measurable to me. Drive gas: 1:20 (so yeah that's lot).

The materials used are not oxygen compatible. But oxygen prices are still low enough to not worry about that too much.

@Miyaru : That‘s quite a price difference!
Who makes it?

Nice! do they also make a booster that can be used for O2 to 300Bar?
My Junior 2 has been pumping He and Ar to 330Bar for the last 20 years using my "OmniBooster" so the only thing I really need is a way to get O2 to 300+Bar.

I've been using the single action one, branded as Scitec and manufactured by Shenzen Scitec Flow Control Ltd, to boost helium and oxygen for over six years now.

TBH it struggles to boost much beyond 200 bar but it works fine.

Thanks for that... I have heard plenty of second+ hand information but you are the first person I am hearing first-hand information from. Can you tell us some more about your experience with your Chinese booster? How close are you coming in the real world to the theoretical specs? How high are you able to boost with what pressure of supply and drive gas? Even the big names like Haskel admit their units fall short. Any frustrations with it?

The gas blenders group on the book of face has quite a few testimonials about the USUN boosters. They seem well liked.
