Some things like this seem to hide from airgunners and stay over in the paintball world. Can someone describe for gas boosters:

1. What they are
2. How they work
3. What they cost
4. What are the drawbacks.....dangers
5. Whether or not they could be used to fill airguns safely
6. Where they can be purchased reasonably

Mr. Bill I posted back to your question call me Id be happy to discuss in depth with you about the booster and any outher type booster you may have found. I have had 4 difrent types before hascal types and dule stage types aswell al very gas gready not very efficent.MY # is 337-258-2542. The simpliest way i can explane it so that airgunners can understand it is take a hand pump, use air to pump it instead of your hands and high presure air on the intake side instead of an open air intake check valve.Ok I no then its a compressor right no reason being it cant compress ambient air as a hand pump or a true compressor can a booster has to have a head presure to boost from. Does this help a little .

Also called: Boost pumps, Boosters, "Bootstrap" Pump, "Accumulator" Pump, Pressure Multiplier, and other names.

1. What they are (if we are talking about the same thing, Lol) in simple form is a pair of pistons that drive one another, one piston and cylinder is small and the other is far larger, they have inlet and outlet valves and manifolds (or hoses) from a low pressure source tank to the pump and then to a high pressure tank. You can also use a low pressure compressor in place of a low pressure source tank.

2. They use the low pressure air on the big piston/cylinder side to drive the small piston/ cylinder side to compress room air to a very high pressure; you get work out of the low pressure air to make a smaller volume of (very)high pressure air.

3. They are expensive; min 1.5K$, as high as 5K$ easily. Depends on the ratio of pressure boost/volume, and can be more expensive than a compressor of equal output. The beauty of them is they are usually going to last forever compared to compressors.

4. No dangers beyond the normal ones associated with hig pressures. The drawbacks are that they are relatively slow compared to HPA compressors, the beauty is that your pressure source(CO2,Nitrogen,SCBA or SCUBA etc cylinder) can be used down to, say; 500psi.

5. It/they have been used by some for decades to fill airguns. I would have gone that route 20 years ago if I hadn't been a SCUBA diver with multiple cylinders to use as a cascade system.

6. Depends on what you mean by "reasonably" Google the names I gave in 1. and you should get a number of hits.

# 2 does not sound corect to me. because a booster needs a head presure to boost up not ambient air or room air as it's stated .it would b a compressor not a booster.

And # 3 is not correct in hole because mine sell for $400 and $700 new.

I can't compare to the "hole" Quality of what you are selling

shootski

#4 very dangerous because the pump can easaly exceed
your guns max air psi in a very few strokes compared to a compressor which is way slower on compressing air into a gun compared to using a booster 3 0r 4 flicks of your finger on my boosters 2800 psi to 4000 psi depending on youy guns air chamber .Not trying to say you are rong but the info is not the some for all boosters especially mine which is very good at boosting and scavaging its drive air source.

hahah ok bad joke

where is my bosster, the hose in my back side is uncomfortable

bob

Nice .25cal info need a lenght on them bullits?

shootski

BOB gettin on ups tracking now oops kid first then ups brb .

I'm getting a much better picture now.

So does it consume more or less air on the high pressure side if you use a 125 psi air compressor?

If you had a SCUBA tank with 2500 psi in it and a carbon fiber tank with 3000 Psi could you then top the carbon fiber tank off at say 4000 or 4200 psi.

The reason I suggest toping of at less than the maximum 4500 psi is for a safety buffer.

I think I'll give you a call but there are others here dying to know/understand how this works.

Thanks for your patience ....I know you said you hate to type.

SETH call me 337 258 2542 jerod

ok 1st off yes u can boost into a scba 4500 from a scuba. But y would u wast all of the air thats allready stored ? Isnt the point to get the air into the gun not your scba . KIND OF BACK ASSWARDS TO ME. Uless u got a gun gready as mine but as i have stated 3600 psi in a 88cft carben fiber tank and a booster n u better pack a lunch a supper heck feed yourself for the weekend .evin boosting your gun to 4900 psi like I do hundreds of shots seth i would think as long as ur not dumping inbetween shots n wasting alot of usable boosted air.DON'T FORGET YOUR INPUT DRIVE AIR CANT EXCEDE 100 PSI USE 90 ITS PLENTY.

For $400 or $700 you supply a system/gun to at least 3600PSI or even 4900PSI on a 90PSI input, like a simple shop compressor? I also don't understand your statement about (scavenging) your airsource supply. Should I call you or do you have a post or online site? What are your work hours?

Found your original message down a few posts but no pictures come up. I wish I could see the picture that you posted in the thread below! I read all the info you supplied and it gives me a clue as to the ratio your friend has built into the system. I don't understand your reference to the "wrist flick" and a few of them result in a boost from 3000PSI to 4500PSI? I guess the pictures would have helped I'll give you a call after the 4th; hope you have a happy one!

Thank You in advance,

shootski

I'll try to relay what I can so he doesn't get the same questions over and over.

Jerod if I get it wrong please correct me.
Quoting word for word is tough on my pea size brain and until today I had no idea how a booster worked.

$400 for a some assembly required booster.
$700 for one ready to go.

90 psi on the low side input to actuate the booster and at least 500 psi in a tank on the high pressure input side.

The scavenging he refers to is on the high side input or your SCUBA tank.
Being able to take say a SCUBA tank with 2000 psi and top off your Haley or Quackenbush to 3200 psi multiple times.

How did I do Jerod?

great Seath I also mean using 90psi to drive with AS SCAVANGE because most boosters require 300psi to drive with. which on a self containd system is killing the source air volume in your scuba or scba . I am not a busness shootsky just a air gun nobody trying to help our sport to grow n help the non wealthy people out who can't swing 4 k for compressed air makes my butt cheeks cringe lol wallet clamping shut it's tight im not. call me 7am to 9pm central please .If I don't answer I'm throwin lead or feedin my son .Im allways on standby .

I have been after a cheep compressor for a long time.
I even have some of the parts, but the end result is far off, and more expensive than a booster.

If you have two tanks, but no way of refilling them. can you use the booster to keep at least 500psi in each tank, if so you would never run out of air.
Or would I have to eventually get one filled else where?

Cheers, David.

david im awake call me 337-258-2542

That's a lot of volume to fill but in a pinch that would be cool if it's possible.
Lot's of finger flicking I bet.

U will get tennis elbow in your triger finger then blame me for your suckey shooting then u will need to take the infomercial all natural joint pain releaf crap lol. Sorry I couldn't help myself!! sure u could boost into your 4500 from your scuba but isnt that air better put into the gun directly for shooting. I BOOST INTO MY 5K 114CI ALL THE TIME ABOUT 15 STROKES GIVE OR TAKE . REMEMBER GUYS THE GUN TAKES RUFLY 1/4 THE AIR OF THAT SMALL CARBON TANK.A SMALL EVIN 2800 PSI COMPRESSOR FAIRLY CHEAP A BOOSTER SCUBA N YOUR SCBA WOULD B FEASABLE FOR 4500 BUT U GUNA SPEND A LOT OF TIME ON FILLING IS IT TRULY WORTH ALL YOUR SPAIR TIME? OF COURSE IT IS IF THATS WHAT U GOT TO WORK WITH. FOR MY TIME 3600 PSI 4.3CFM IS ACEPTABLE FILL TIME BULK FILLING A PAIR OF 110CF SCUBAS A PRESURE SWITCH CUT OFF MANDATORY I PIDDLE OOPS FORGOT THE COMPRESSOS RUNNING LOL . DO AS I SAY NOT AS I DO REMEMBER 2AM SHOOTING IN THE SHOP IN TOWN.
