Altaros gas booster hybrid to fill bottles from bottles ?

Can the hybrid unit fill a 6.8 bottle from another say 6.8 bottle ?
I asked the manufacturer but never got a clear answer . I understand a booster can fill a airgun sized , .5 bottle from the larger tank at a lower pressure then desired fill amount or a common garage compressor but if this is possible even if slower then a Chinese pcp compressor .
 
I doubt the manifold and fittings on the input side are pressure rated . Story time.

I worked on an anti satellite weapons system for the US Air Force back in the 1980's. If you're curious look up "ASM-135." We used a purpose built pressure intensifier to boost the pressure from a 6,000 psi N2 bottle to 10,000 for use in the onboard presure bottles that powered the hypergolic liquid fuel attitude control motors. We never used the booster unless there was an absoulte minimum of personnel present.

One night, we were tasked with boosting the pressure in the onboard missile pressurization bottles for an upcoming flight test. This intensifier pump we had used shop air to drive the piston. Whooom POP, Whoom POP, Whooom Pop, Whoom POP! You get the idea. When we had reached ~7500 psi in the system something exploded. The loudest explosion I've ever heard. I was convinced we'd blown up the eiither the booster or the pressure bottles in the missile. It turns out it was just the drier on the shop air side that exploded. I guess the one way valve failed.

You actually can do a variation on what you describe, but it will cost a good bit as you will need regulators that can get the air pressure down to the right level to drive the booster - and in the end I doubt you would actually choose to do this.

But the biggest thing is that you can only fill smaller bottles than the one you are using to drive the system this way - if you have a 6.8L bottle at something like 3000 psi, you could probably get a 1-2L bottle up close to max. You have to remember that you are "wasting" much of the air in the tank by using it to drive the booster as well as to be the source for the air, so you will end up with less compressed air when done.

I think you would do much better using a shop compressor to refill that 6.8L bottle with the booster . . .
 
I think you are thinking of the 1 extreme puts out. https://hardairmagazine.com/news/th...-your-pcp-to-a-higher-pressure-than-the-tank/

 
Trying to figure a way to make my Chinese compressor last longer and this seems a viable route using a booster and not using the compressor to fill guns to 300 bar . A bonus would be to be able to fill bottles .
It’s hard to compare the various gas boosters not being from a pneumatic background . The posts on forums helps to give one ideas though .
I'm the only guy around that I know of shooting pcp in my area but there are paintball guys .
I am a leshiy 2 .30 and impact m3 .35 into this hobby plus planning an airfoece texian at some point and need lots of air . I don’t see these small compressors lasting too long , disposable at best .
Could someone who knows about the various brands of boosters do a comparison that’s easy to understand ?
 
Altaros units are excellent. Bottle to bottle booster is more efficient at boosting bottle to bottle because it won't waste half the drive air. The hybrid is the best of both worlds because it can boost 100 psi to 4500 and work in bTb mode as well. You can use shop air compressor for the driving portion of the boosters. You can also regulate bottle air to 100/150 psi to drive the booster. On the "source" you can use regular air, nitrogen or helium. I use one to fill 6.8 liter tank, when I don't want to deal with the compressor.

Yes, if you have 3000 in the bottle you are filling, at least 2600 in the bottle you are using as the source AND you use a shop air compreasor as the drive air, so you don't waste any bottle air. Then you will get 4500 in the bottle you are filling and 700-900 psi in the source bottle. FOLLOW THEIR DIRECTIONS
 
Relax, the sky is not falling, if you follow what Sergei advised you will be fine. As some here have written, HPA is very dangerous if used incorrectly, but so is driving a car to work. But they don’t own a Altaros Booster.

I do not own or have I used a Altaros bottle to bottle Booster, however, I have used various boosters over a 10 year period, including the Altaros Shop driven air/supplied unit I have used for 2 years.

The first one, a booster I had 10 years ago just scared the bejesus out of me, however at the time scuba set up units did also, however, I was uninformed, if used properly they are safe. I sold or traded that unit to Doug for cash or his splendid AF mods. He used it with helium, and I think it is still going, and he is still with us.

Then came 3 generations of Shoeboxes, I would still be using them if support had been available.

Then I purchased the Altaros Booster 2 years ago. I ended up with a bunch of money in it, but it works, it is robust, very cool running and very quiet and above all is safe. All of my journey on my system has been guided by the advice I quickly received by email from Altaros and AGN member Chickentheif, an abtasive fellow but a walking vessel of Airgun/compressor knowledge none the less.

At the time of my purchase, I could have gone with the Bottle to bottle system, but I have no transportation to a dive shop and I am not a diver. My daughter and son-in-law have 80 or more scuba tanks, but they live half a world away in Maui. So I went to a shop Compressor driven/supplied unit. I eventually went to running 3 quiet CaliforniaAirtools units to reliably run my Altaros Booster. It is Shoebox slow, maybe a bit faster and in 2 years flawless, advice and rebuild kits are quickly coming if needed, I bought a few rebuild kits, but that is just me.

If I lived in Maui, I would be using the bottle to bottle unit, which I have read is much faster.

HPA is very dangerous, but following the instructions you get from Altaros and knowledgeable members experienced in the equipment your inquiring about will keep you safe.

Good luck on your quest for knowledge,

P.S.

I went with the 3 CAT oilers 110V compressors because I did not want the oil smell a large powerful compressor can put out, nor did I want to retire my shop. My 3 CATS are easily replaceable and CAT tech is just a phone call away. The set up I run is quiet enough that I can’t hear it unless I am in our attached garage.

My set up.
