Economical PCP fill tank

[fishcrf450r]

Will a 45 min scba filled to 4000 psi give more fills than a 80 cuft scuba at 3000 psi ?

[sixshootertexan]

The 45min(66cf) will fill a Disco from 1200-2000 110 times while the 80cf will fill it 100 times. So yes the scba will give you more fills.

[fishcrf450r]

Is that with a 4000 psi fill ?
That is the best fill i can find .

[sixshootertexan]

yes with a 4000psi fill. You would get more fills if you were able to fill the 66cf bottle to 4500.

If you are just filling the disco then save your money and dont buy a 4500 psi tank you wont need it. Just find a good used scuba tank and use that. You get plenty of fills in a disco and it has no shelf life if you do not damage it unlike carbon fiber tanks.

I started with a Disco and pump.  Found SCUBA tank on Craigslist for $60 - needed hydro.  SCUBA shop fills it for me $60 for 12 fills.  Thank is marked "not for SCUBA" and they're happy.  I bought a Ninja fill station and fill line off Amazon.

I still use this with my Marauder, which I usually fill to 2200psi.  I also just bought a QB79 + 13ci Ninja tank - also fill to about 2200psi.  This all works well for me, although on occasion I start thinking about setting up a cascade.

Do some research on aluminum SCUBA tanks before you buy.  I forget the specifics, but tanks manufactured before date 'x' were of a different alloy that was/is prone to failure.  SCUBA shops won't fill these - and yes, they can explode.  Find out what the markings mean and check them before you buy.

I'd like to have a high pressure SCUBA tank - these can be filled to 3400psi or there abouts - then I'd fill the Marauder and QB to more like 3000psi.

Anyway, as long as you can get SCUBA filled, it's very serviceable for use with a Disco.

Aluminum scuba tanks manufactured after 1989 are still serviceable.

Actually 1989 and later.

As a PSA, here's one link to info on SLC failures in aluminum tanks.

Quick story - Luxfer tanks made 1989 and after should not be a concern.

Bought tank set up from TopGun airgun on June 4 paid for UPS shipping was sent USPS when I questioned him he changed website to say USPS shipping was standard. Also increased rates. When I received tank set-up and filled not only was the gauge broken but both quick disconnect fitting blew at 3900 when he had told me over phone that all fittings and hose were rated at 5000psi except t fitting which was 10000 psi.
Filed complaint which paypal but while waiting replaced both quick disconnects. Finally got dispute settled in my favor but had to return as I bought it. No way to prove gauge not working when I received tank set-up and would not be reimbursed for my shipping back to the rip-off artist so decided to keep it
 Be advised this person will tell and sell you one thing and ship sub-par parts to you and claim they are up to what you need. Currently am only filling tank to 3000 psi till can replace complete fill assembly.
Again cheap tank set-up ISN'T so CHEAP!!!   

[pepegraves]

Yes, I too am interested in getting a larger fill tank. I just need help with the correct line to attach to the tank to fill my rifle... I'm kinda thick on this subject so, Pictures and product numbers, etc will help tremendously 

The fill line for be for this tank:

I just ordered a 30 min interspiro scba with fresh hydro and 5-6 years left and a joe b fill station with male to male foster adaptor .
All for under $300 shipped .

[fishcrf450r]

Ok , i just upped the cost some with a slow flow valve fill station with dual gauges from joe b.

[fishcrf450r]

Ok got my 30 min tank and joe b slow flow valve fill station with micro bore hose .
Got to say that I'm glad that i upped to getting the valve with the fill station built in rather than just the fill assembly .
Not only is it clean and compct , it is very controlled and now i can get it filled at a scuba shop or paint ball shop with the foster fitting or din 300 .
Also i was concerned that the 30 min tank would be too small capacity wise.
But now that i have used it I'm glad that i didn't get the 60 that i wanted .
The 30 is a reasonable size to carry and transport and givving me plenty of fills .
I've got 10-12 fills at 1700psi on my fdpcp manny of them run down to almost empty and still have over 4000 psi left .
As others have said joe b stuff is top notch quality and worth the few extra $$$ .
Pay once be happy for years to come .

[pepegraves]

There are plenty of relatively fresh used tanks out there. By way of example, here's a new 2008 4500psi SCBA for @265 shipped.

You can pick up a fill rig from a number of suppliers including MAC1, Air Tanks for Sale, and eBay.

Always check the specs and ask all questions before buying anything online, and make sure you can find a local fill before picking up a tank.

I think that is a good buy, they got at least 8 years of use left... 


Yea, I took you guys advice and got a 2008 model 60 min tank...Took it down to Carolina Carbonics in Greensboro yesterday To have it hydro'd and filled... JR and his wife are good people... They're a welding outfit so, I was surrounded by NITROGEN TANKS ....I can see moving towards nitrogen in the future...I just have to get the right adapters for it....But thanks for the ebay tip, it worked out good for me

Sorry I am not allowed to post external link ( is this a new member restriction?) but you should be able to fill  in the missing

Vendor

air tanks for sale

SCBA Hose assembly



$149 plus $14.50 shipping

Then shop E BAy for a deal on a SCBA  4500 PSI Carbon Fiber tank. Prices run from around $100 to $300 delivered depending on if they 30,45 or 60 min and how many years left on thier 15 year life span and if the Hydro inspection is current or not.

Chart with  cu. ft. capacities for these and other here and a great,  easy to use fill calculator.   For the Discovery use 135 cc for fil capacity.

calc.sikes.us/2/index.php

 


Added: SCBA  as used by Fire Departments are equipted with a regulator which has CGA 347 threads. Your local Fire Station or the closest one which has a fill station  may or may not be willing to fill one for you , some will and some will not.

Non will fill one which is past 15 years old or does   not have a current Hydro Test.

These regulators have a hand  valve, pressure gauge and safety disc                                           

[fishcrf450r]

Got to say that having this tank has not been  economical at all...
Do you know how much it has cost me in pellets to try      to use up $5.25 worth of air.
All kidding  aside,  it's  been great and has me shooting more.

My only statement will be this.  Carbon fiber tanks are good for 15 years, and only 15 years. I am disappointed that someone would knowingly tell another that a tank that is 14.5 years old, will be good for another 5 years, just because they did a recent hydro.  It ain't so.  Please read DOT special permit 10915 Section 7, paragraph C1. Bottom line, 15 years.

Here is the link to it:
https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=dot%20special%20permit%2010915

You can't get a tank hydro'd on the 14th year 364th day, and get another 5 years out of it, or you'd be getting a 20 year (minus one day) tank.   Even the mods from thsi forum will say the same as I saw them post similar recenlty.   

I just don't want to see a bunch of guys getting steamed up after Jan 2016 when their dates run out. 

Please don't bring up the subject, "They are still good if you have a compressor", etc. Not my intent to discuss nor debate.  I'm talking legally, and for the 95% those of us that will fill at a Firehouse, SCUBA or Paintball Store, they won't fill them after 15 years (unless they just happen to not notice it has expired).

Best to all of you.

Despite opinions that HPA regulations are overly conservative, I prefer not to share space with an uninspected, untested, out-of-certification high pressure tank.

[Case Stuffer]

Yes 15 years per  DOT regulation  and then there is this US Navy testing and its' findings.

"Cylinders are also inspected at the appropriate three- or five-year test interval by
SCBA Cylinder Life-Extension Study, Final Report (August 2012) 2-2
certified testers prior to hydrostatic testing. About half of all visual inspection failures observed
are due to wear or damage experienced from exposure to knocks and abrasion during frequent
firefighting drills on Navy ships. The other major category of visual inspection failures consists
of those induced by hydrostatic testing—including cylinder stem thread galling due to improper
removal and reinstallation of the cylinder valve fitting, and to interior cylinder surface contamination
or corrosion caused by improper drying of the cylinders after hydrostatic testing.
Hydrostatic testing of the cylinders is accomplished by removing the valve from the cylinder,
threading on a test connection, filling the cylinder with water, pressurizing the cylinder to fivethirds
(5/3) of service pressure, and measuring cylinder expansion. Based on findings regarding
testing-induced failures and the high hydrostatic testing false-positive rate, it is likely that more
cylinders are damaged by the hydrostatic testing process than by service handling and usage."

I have been looking at SCBA tanks for use with a Hatsan AT44 and there is a lot of confusing info out there. Not all of it is correct. For example, I read a number of sites that claimed that you need a cga 347 to din 300 adapter to fill a 4500 psi scab tank at a dive shop ( if they could do it at all). This is not always true.

My local dive shop in Westchester NY can fill a 4500 psi scba tank without needing any additional fill adapters so it is worth calling before wasting money on adapters. Some of the carbon fiber tanks sold by air gun stores use the paintball tank valves and these are the ones that can't be filled at many dive shops without another adapter so you need a paintball store.

My local dive shop quoted $45 to get a hydro test for a carbon fiber tank and said it takes 2 weeks as an FYI.

The adapter I would need to buy is one for filling the gun. The Hatsan uses a 1/8" BSPP connector and I haven't found any scba (cga 347) to 1/8" BSPP adapters yet. I have seen a number of scba to "quick connect" or scba to paintball adapters but I can't tell if these fit the foster fittings that you get on the Marauder rifles etc. either way, the adapter cost $80-$170. If have seen cheap 1/8" BSPP to foster adapters ($8).

A used 45 min scba tank with 5 years + left is not cheap by the time it's hydro tested, filled and connected to the gun but it is way cheaper that the $900 being charged for new ones at air gun shops.

I was going to buy a used fire fighter tank when I saw spare cylinders for the Hatsan rifles for $90. My issue with the pump was needing to spend time filling the gun at the range ( it made me feel silly). For the price of a used scba tank, I could buy 4 (or more) hatsan cylinders which would give me close to 150 shots so I could separate pumping and shooting.

I have also read about people using nitrogen tanks to fill their guns. Apparently nitrogen tanks are cheaper than hpa tanks and relatively easy to get filled.

All of the options seem to not so good a bit in their own way...
