Pump To Maximize Air Use When Shooting Big Bores While Tethered

I read about a pump that assists airgunners in using more air from the SCBA tanks before needing to top off the tank. These pumps didn’t require a power source and I don’t remember the make and model of them. I think they were called Xtreme Booster pumps, but I’m unsure. The only boosters I see around now are booster pumps and they look like they need a low-pressure shop compressor to power them. I’m not interested in anything like that. Anyone recall the type of pump I’m referring to? Are they still made by a reputable company? I’d like to look into this sort of product .
 
The thing that makes this version so much more than the base version is that it needs to add in a high pressure air regulator to bring bottle pressure down to under 10 bar to feed and run the pump.

I suppose if you have one already that could do that, you could plumb together a system that would let the base unit fill off a bottle too, and that could save a bit of money . . .
 
@AlanMcD Thanks for that input. I don't know much of anything about these units. I used to read about them in old threads and didn't think I'd have a use for one. Now that I'm considering one a few of the companies that used to produce this sort of device went out of business or just stopped making them as far as I can tell. Whatever I decide to get, I hope it is well built and long-lasting. I still have a lot of reading to do to gain a better understanding of what I'm looking to get, how I can be used, and what a realistic maintenance schedule looks like. I hope that disposable parts for maintenance are easily accessible.
 
The altaros units are very good. Had 2 of them. Seals are easily available from them and can be sourced in the use from metric seal suppliers. The only thing better is a $4000 scuba booster which are heavier and harder to rebuild. The only reason I rebuilt mine is I bought a used one that had been abused. Rebuilt it, then tried to duplicate the failure by running off 15hp compressor as fast as I could. Didn't duplicate the failure because it was obvious that I started generating heat and backed off.

Get the b2b version and save a little money and nitrogen/scba air by deleting low pressure regulator and using your regular shop compressor for 100psi air to cycle it back and forth.
 
@Sergey1972 In the video it appears that some sort of USB 5w power bank is used to power the B2B. I’m really only interested in squeezing more air from my SCBA tanks. I don’t have interest in using this pump to fill them.
The usb is used only to cycle the electronics, even a little power bank will last for hours. Getting more air use out of a big bottle is the. Reason I suggested the B2B version which is the bottle to bottle. It compresses air in the right and left stroke and only uses hundred psi air to move it left and right.

@Sergey1972 What I’m not clear in is this. Is that 100 psi that you’re saying is required to move the air from bottle to bottle coming from the larger bottle or is an external source (a small shop compressor) required for this function?

Yes compressor is the external force.

usb cycles electronics. Electronic valve controls 100 psi air to piston that moves the compression pistons "Drive Air". 100 psi air can come from shop compressor or be regulated down from the bottle (save the money on the regulator and use shop compressor). Bottle pressure air feeds the air that is being compressed by the 2 compression pistons and boosted to 4500 psi (input can be 800-3000 psi "supply Air").

Standard version uses shop air at 100 psi and splits it for both functions - driving air and supply air to be compressed. It has 2 stages of compression that are sequential (upto 800 psi then to 4500 psi).

Standard version with B2B option - uses only the stage that boosts 800 to 4500 psi (left half).

B2B version - Right and Left stage are identical and both are used to boost "supply bottle pressure" to 4500 psi. You can buy the regulator to regulate bottle pressure to down 100 psi for "Drive" air if you are in the field or you can supply a compressor to provide the "Drive Air" and save money on the regulator.

The 2 American boosters only worked for B2B and only had 1 stage of compression. They were $1250-$1500, I think - heavier, did not cycle automatically. You had to push the button for each compression cycle. I never had any of the American ones. I did have a Haskel Scuba booster and it was a beast .
