Title: 4500 psi tanks
Post by: mlrs_27m on December 17, 2010, 03:22:36 PM

I just ordered one from Joe Brancato, FEDEX says it'll be here on the 21st  :)

Joe is great to deal with.  Spoke to him on the phone when I ordered, he went over all the details of the tank, hose, fittings, etc, was happy to answer all my questions to make sure I knew exactly what I was getting  and he kept in touch with me after I ordered to keep me up to date on shipping.  Here's his web site link...

http://www.airtanksforsale.com/ (http://www.airtanksforsale.com/)

Matter of fact, the Christmas special he's running on his "Great White" 88 cu ft 4500 psi carbon fiber tank comes complete with everything you need to air up marauders or disco's right from the box  :) Check out his stuff and give him a call.

bought my first one( 30 minute-44cf tank with 7 years of "shelf" life left) on ebay for $150 delivered. bought my second one-same size- with 5 years shelf life remaining on ebay 2 weeks ago for $120 delivered. neither is currently hydroed but have my own compressor( shoebox) so i don't care. both tanks look almost new. in fact i am filling the second tank right now with the shoebox. it's slow but a heckuva lot cheaper than a full size compressor and nobody locally can fill a tank to 4500psi. that is the main thing you must check about. most paintball stores claim they can fill to 4500psi and they can- as long as it is the usual SMALL paintball tank!. walk in with a 44,66, or 88cf tank and watch how fast they say "sorry, can't fill one that big"!!!! and for those who claim you can fill them at fire stations- well, maybe where they live but not in many areas- too many liability issues. BEFORE YOU BUY AN SCBA TANK, BE "dang" SURE YOU CAN GET IT FILLED LOCALLY- or buy a $400 shoebox and kiss fill worries goodby.

Try paintball forums of sites. They are your most lickly place to get one. Amazon also has them.

I think scuba shops will also fill them for you. Or if you are friends with a firefighter, he might. They use high pressure air tanks(HPA tanks) for breathing,

I got mine from ebay a few months ago for $125 delivered.  Got my valve/gauge/hose setup for MROD from Joe Brancato.  I get mine filled the same place I had it hydro-tested.  You can click on the applicable state from this list below and find out who can inspect/fill in your area. http://www.phmsa.dot.gov/portal/site/PHMSA/menuitem.ebdc7a8a7e39f2e55cf2031050248a0c/vgnextoid=18dee6285188e110VgnVCM1000001ecb7898RCRD&vgnextchannel=90892f5484d87110VgnVCM1000009ed07898RCRD&vgnextfmt=print (http://www.phmsa.dot.gov/portal/site/PHMSA/menuitem.ebdc7a8a7e39f2e55cf2031050248a0c/vgnextoid=18dee6285188e110VgnVCM1000001ecb7898RCRD&vgnextchannel=90892f5484d87110VgnVCM1000009ed07898RCRD&vgnextfmt=print)

I couldnt find anything on ebay so I ordered the whole set up from Joe. It hurt to spend that much, but I think it will worth it.
Title: Re: 4500 psi tanks

just checked ebay and right now there are 2 4500 psi 44cf tanks for sale-1 with 7 years left( $150 shipped) and 1 with 11 years left($225 shipped). just FYI

Man, I'd jump-on one if I had a shoebox compressor.  No close fill-stations, or welding supply shops or fire stations...nada, zip.

I'm pumping the disco and marauder, right now.  No biggie if I don't shoot below the sweet spot, on either. 

But it surely would be nice to have bulk fill HPA for both rifles.  Maybe someone will have a used shoebox and tank combo for sale...prolly when it snows in July.

My dad told me I could have a BB-gun when it snowed in July.  Man, I couldn't wait! I must have been 5 or 6, and not being street-smart at that age, had no idea why mom laughed at it.

Well, 2 years later @ 8 years old, I got a Daisy 1894 carbine.  That was only 47 years ago, if memory serves (sometimes, it doesn't), and I've been shooting ever since.

Hello guys,  you can pm me with questions re scba tanks if you like,  im the guy listing the tanks on ¥bay.  I posted 2007 tanks on the classified section with absolutely no interest on this forum.  It has since fallen off the screen.  Tanks are good deals for the life they hav on them

I bought the same rig LIH has from Joe about a year and a half ago. It's perfect.

Some day I may get a travel bottle for hunting.

I just received my tank/hose rig from Joe the other day and it's awesome :)   

I'm thinking along the same lines Dave regarding the travel tank.  If I can save up the $ I may order one of Joes smaller "guppy" tanks for hunting use.   Hmmm, maybe for my birthday  :)

I'm also looking into a package deal, with a buddy or guppy bottle.  Nitrogen rental is through the roof, no dive shops around, no stations willing to fill bottles/tanks except their own, and CO2 is just a big no right now (cold).

Looks like a small bottle filled with a shoebox compressor or my hand pump, is going to be it.

Joe's kit looks good, but not willing to spend that much moolah right now.

you guys need to learn to use the ebay search engine. as the guy who posted 4 posts above stated, you can buy tanks with 5-8 plus years of LEGAL service life left for well under $200- and that doesn't take into consideration how long you can use them with your own(shoebox) compressor.  i bought 2 thirty min(44cf) scba tanks for a cascade system for my shoebox for under $275 delivered. and cascading 2 smaller tanks will give you more fills before recharge than 1 single tank of equal cubic footage( see Joe Brancato's website on cascade systems). BTW, Joe the go-to guy for hoses, adapters, gauges, etc.

I talked with a former business fire inspector for the county (he now works where I do), to try to pull some strings, but he has been out of the loop for so long, his contacts are gone.

He did say just go to the nearest BVFD, with a box full of donuts, and shoot (no pun intended) the bull with 'em, and they *might* fill a bottle for me.  Very funny.  Donuts seem to speak a universal language.

I already got a polite no from the brass in two counties,  but never thought to use trickle-down a few ranks and hit the troops where it hurts, the beltline.

I have been informed that if you can pay from 18-22 dollars per year of life left then its a good deal.  This was on another forum and seemed to be a concensus.  Adapters are another story.

went to the local fire station where all the substations filled their tanks- no go because of liability issues. that's why i bought a shoebox. hose/adapters cost $110-135 plus the tank cost.

Hi...
over here theres no way a fire department will fill a tank for
joe blogs puplic walking in of the street...
as yer said liability issues / they would need to adjust the setting
on the compressers fill psi..then reset them for there own use...
etc etc....
But its something that would never really come up here...can't
think of anywhere here you could live more than a hours drive
from a dive shop...15mins would be avarage?

Using generalized numbers, the ideal  4500 HPA/PCP setup might include...

$500 - 4500 Tank & Hoses
$500 - 4500 Shoebox & Hoses
~~~~~~~~~~~~~~~~~~
$500 - PCP of choice
$300 - Glass & accessories

Did I miss anything?  (besides the guppy tank, lol)

I think scuba shops will also fill them for you. Or if you are friends with a firefighter, he might. They use high pressure air tanks(HPA tanks) for breathing,

Most fire stations will not fill them. Too much liability. I am fortunate to have a scuba shop 1 mile from me will fill to 4500 psi AND he asks to have one day as he fills it, lets it cool till next day and tops it to 4500. If they just fill to 4500 tank is very hot and when it cools you have less than 3800 psi in it.

My scuba shop is the only one of 5 in a 25 mile radius which will fill to 4500 psi.

Also NONE of the paintball stores in my area will fill a big tank! Most paintball stores are used to filling the little "cubic inch" tanks and NOT the big ones. Just ask them if they will fill a 550 cu in (88 cu ft) tank or 225 cu in (44 cu ft) tank.

So yes, make darn sure you can fill your tank before purchasing one.

Also make sure you can drop it off and they will fill one day and refill the next. Last fill I got he told me his compressors were running hot when he filled it and next morning it only had 3500 psi in it. With an unheated compressor he was able to top it to 4500 with no heating the following day.

Those tanks have an expiration date for a good reason. And to not have them inspected and hydroed is to risk your life. I recently had a chance to get FREE 4500 psi tank from Joe Brancato. It was out of date. I passed as my life is worth a *(&^ of a lot more than being niggardly and saving a few bucks.

When you are dealing with 4500 psi you need to play by the rules. They are there to protect YOU!

Having one of those blow up will ruin your day for sure even if you are not there when it happens. If you are near the tank when it happens it will ruin your life if not terminate it!

Folks, playing with 4500 psi is not safe, is unwise, and is not worth the few pennies you might save. Treating 4500 psi with disdain by not having the tanks properly hydroed and inspected is just plain stupid. Trying to extend the life on a tank which has expired is simply insane!

Post by: Gary on December 23, 2010, 07:50:50 AM
I have to agree with the statement that 4500 psi is not to be taken lightly, but on the other hand in Europe the same tanks have a 30 year life span. Plus when a cf tank fails it does not explode like a metal tank.  They split open no flying metal at least that is what I have read. Have also read that there is some talk about extending the cf tank life for a longer time frame.
Sometimes I think our goverenment is a little over the top protecting us from ourselves.
Whats a man to do?
I do have a shoebox compressor so the ability is there just don't think that filling a tank that at the end of its life span,or out of hydro is a good idea. It may work fine,but betting my life on it. NO WAY.

What do you guys think of using an out of date (4500psi) tank and only filling it to about 2600 psi with a 3000 psi scuba tank.  It is a 68ci hpa from an 80 cf tank.  I think I can get a few fills for the times  when I need a remote small tank.
Opinions?

Post by: dollarhunt on December 23, 2010, 09:46:41 PM
DOT regs are apparently being re-written at present to extend tank life to 30 years. regardless, since my first tank doesn't expire for 5 years i am not going to worry anytime soon- and saving $400-500 PER TANK over new ones is(at least to me) a significant amount of money. my money, my life, my choice.
Title: Re: 4500 psi tanks
Post by: r1derbike on December 23, 2010, 09:53:30 PM
I'm not going to worry about it either.  Have no way to fill a tank, at the moment.  Might be able to fill a midget tank when the shoebox compressor wait is over, but it looks like my place in line is several months away.

Meantime, filling the Discovery and Marauder with the Benji pump, which is getting a bit "draggy" on the upstroke.  Have used recommended cool-down, and slow pumping.  Use it 'til it pukes, that's my motto!

Im with dollarHunt.  Tanks can be bought cheaply, but safely. Purchase price of tanks at $20/year of use is very cheap in this hobby.  Come on we're talkin about 3 tins of pellets per year.

Super...I saw your name on the waiting list.  Please let us know!

I've already got a huge 125 psi compressor/tank, that should work nicely as its first stage, when my number finally rolls-around.  Only way I'll be able to fill the rifles, without the hand-pump.  It's not hard at all to just keep the rifles topped-off with the hand-pump.  Very easy, really.

Anyway, please post thoughts!

be absolutely sure that your shop compressor is OIL LESS.  otherwise the least amount of vaporized oil in the feed to the shoebox will screw it up. and don't assume an inline filter to the shoebox will solve the problem. Tom Kaye( the shoebox designer/builder) is adamant about an oil less feed. the good news is that you can buy such a feed compressor at Harbor Freight for under $60( got mine at Home Depot for $100). just FYI.

I got my oilfree first stage pump from harbor freight, 3 gallon 85-110 psi.  Cheap, 59$.  I believe.   Guys dont use tanks past their 15 year lifespan,  get them hydrotested,  it doesnt cost that much.  I got a shoebox comming and i will not use it past 15 years,  but if dot ok's their use to 30 years, then i guess there is a lot of hype and phobia spreading out there.  But until thst happens retire then after 15 years,  tanks are just too cheap to not get nother used one with a few years of life left ib them.

I picked-up the Coleman for 150 on clearance, a few years back.  Been a good one, so far.  Will be interesting to see how much and for how long it kicks on, with the shoebox compressor.

*(&^, you are good to go now and with a tank that big, your feed compressor won't kick on much at all. consider putting a cheap moisture filter in the feed line if you live in a high humidity area. got mine at Lowe's for about $10 and it can be drained when needed. and limit the input pressure to 100psi or you damage the shoebox piston O rings.
