SCBA Carbon Fiber PCP Air Tanks

[@AtlasJotun]

Thanks. My brother's b-day is in a few weeks, and I want to get him a tank but didn't know what I should be looking for. This is excellent information in that regard.

[@0011py]

Joe is a good guy; he taught me patiently from zero knowledge about air guns and tanks! I shall return as a regular customer.

[@harryv6147]

Joe Brancato, you are the man! That was the best explanation and education of PCP airguns filling and air tanks any person would ever want! Great work! I can see you have great equipment and knowledge! I have watched other videos you have made and they are all good. The videos you have made are valuable to anybody that is interesting learning about airguns technology and airguns and equipment in general! A knowledgeable air-gunner is a safe air-gunner! Thank you!

[@AirGunScientist]

Thank you Harry. Please tell your friends about me. I'm shooting for 10,000 subscribers.

[@WEALRO]

Christ it's the longest explanation ever and repeating over and over , Benjamin does this in about 2 min segment with 3 short videos and is much better then this d-bag

[@davidoakes3878]

I'm glad I ran across this most informative video clip. I have been thinking about getting and shooting a PCP airgun. While I Have experience with springer and pump airguns, PCP will bring new challenges. There are a lot of ways to make , store, and use the power of these guns. Good job, Joe. Thanks

[@AirGunScientist]

Thank you. You're welcome. Merry Christmas and happy Holidays

[@dougwiles7639]

PCP is the way to go. I have a Dragon Claw dual tank .50 and a AEA Element Max .58 and I love them immensely.

[@UFOHUNTERS2]

thanks for the info Joe... it;s a great idea to just connect an air gun to a tank and shoot until all day at one spot.. like at a shooting range

[@AirGunScientist]

Yes, we have regulators to allow that to happen.

[@Nykkytta]

Thank you Joe. I am new to the hobby, you make it much easier to understand it.

[@AirGunScientist]

Thank you for the feedback

Cool shop and not just tanks but FX airguns in stock too! Got my "fully loaded" Great White tank and am lovin' the break from the hand pump. Since I'm local, I can come by for free refils for life!

[@AirGunScientist]

We enjoyed having you in our shop. Best wishes and safe shooting!

[@GertTown]

It doesn't even talk about the smaller scott type tank which is the most available one even though there is one on the table.

[@AirGunScientist]

The tank on the right is the same size, shape, etc. as the Tiger Shark next to it ( (2nd from Rt). The tank on the right is only to show the difference in the "Fireman's valve" vs the DIN300 on the Great White, Tiger Shark, and Guppy.

Still learned a lot from this, thanks Joe !!

[@AirGunScientist]

Thanks for your feedback

[@Bumpyi64]

I was bitten by the "Air Rifle Bug" last Summer at age 60. (they weren't as I remembered as per the 1970s) but the two .22 airguns I bought were break-barrel. OK, my question: I recently purchased a Umarex Air Sabre. Which attachment will I need to buy to accompany the SCBA tank I'm convinced to buy? I don't wish to purchase an HPA air compressor for only my Air Sabre, but, I discovered a hand pump is a LOT of WORK at now age 61! Can anyone help...?

[@Kcrunchymunch]

Thank you so much, I searched and watched many videos trying to learn what I need to go mobile with my PCP airgun and I was still not getting it in regards to all the different valves and names they're called. Thanks for clearing that up. My only question is what steps do I use to air up a tank with my compressor?

[@AirGunScientist]

You need a 4500 PSI Compressor www.topgun-airguns.com/?s=compressor&post_type=product www.topgun-airguns.com/product/alkin-w31-mariner/

[@bluewater454]

Wondering what the advantage of carbon fiber is over aluminum, aside from the obvious weight difference. The carbon fibre tanks are a bit pricy, and I have been told that they only last about five years. What do you think? Is aluminum more durable?

[@AirGunScientist]

Carbon Fiber tanks are good for 15 Years (though a 30 year re-cert is in the wings) and need a hydro every 5 years. These can be fitted with a TJ3 valve. Carbon fiber tanks are capable of 4500 PSI Carbon Fiber cylinders with 9 Lbs (Tiger) and 11 Lbs. (Great White) Our Carbon Fiber tanks come standard with Slo-Flo valve, hose, gauge and bleeder (nothing else to buy) Aluminum tanks are good indefintely, but must be inspected EVERY year. Alumin tanks are only good up to 3500 PSI. With Aluminum tanks, one needs to purchase either a SCUBA Yoke Hose or DIN300 Hose Asembly experthpa.com/cart/cart.php?m=product_list&c=22 Aluminum tanks are designed for SCUBA diving, and must be neutrally bouyant, hence intentionally made to be heavy (45 - 55 LBs) Heavier, less pressure, need to purchase Hose Assembly There is an aluminum tank that is fiber-glass hoop-wrapped (about 110 Cu Ft). It is the worst characteristics of both. It is designed for SCUBA diving, and must be neutrally bouyant, hence intentionally made to be heavy (45 - 55 LBs) and needs more frequent Hydrotesting, and has a shorter overall life. Since it has Fiberglass instead of Carbon Fiber, It must be hydro-tested every THREE (3) years and good for 15 years and then that's it. There will be no re-cert to provide additional 15 years and pressure is only 4350 PSI. Basically, heavier, more re-certs, less pressure, and shorter life and need to purchase a Hose Assembly. Hope that helps.

[@bluewater454]

Thats great. The info I got on carbon fiber was apparently not true then. Thanks for that answer.

[@mirageycq]

Thank you sir, very informative vid. One thing, can a scuba company be able to refill my tank like the small one showed in your vid? Thanks

[@AirGunScientist]

Possibly. You need to call them to confirm

[@rabidcougar6465]

I have an APEKS regulator attached to my 4500 PSI Omega tank. The other day I took it to a dive shop to have it filled up for the first time since I bought it. While filling up my rifle, I noticed it was leaking air from the Din adapter that screws into the regulator. Could the "O" ring at the end of the adapter have been damaged? Additionally,, the tank has a date of 06 17 and the guy at the dive shop said the next time I have the tank filled, the tank is going to have to undergo a hydro static test . Is this true? Hopefully you will read this and help me out. Thank you

[@AirGunScientist]

Yes, the o-ring is probably bad and needs replacement. That tank is almost 5 years old, and hence will soon need to be hydrotested (every 5 years).

[@tshooter4419]

Nice Job Joe.

[@resoluteretreat1532]

Thanks for the video . . . I'm hoping you will do a video on tethering your air rifle . . . and proper use of the regulator you sell.

[@AirGunScientist]

OK, Will do as soon as I get back from the NC Airgun show.

[@AirGunScientist]

Wish Granted! Check out the video on tethering. It was just made for you and Mr. T.

We could maybe do an in-depth video. Comments like these are helpful.

[@ronbianca1975]

Hey Joe,what about filling tanks with hellium?

[@AirGunScientist]

For sure. And you get an increase velocity too! (almost 50% increase). But it's costly.

[@mikepi660]

Thanks, very informative AND professional Sir,,

[@getore100]

Hi Paul. Thank you for a very informative video. Excuse the ignorance of the question I'm about to ask. If I use a standard 3000 psi tank, I fully understand how and why I would get less fills on every progressive fill after the 1st since now, my tank has something less than the original 3000 psi. Wouldn't the same thing happen on a 4500 psi tank? For instance, let's say I have an Umarex Gauntlet that takes 2900 psi. I will be able to fill my Gauntlet X amount of times all the way to 2900 psi until my 4500 psi tank drops below it's internal pressure of 2900. As such, my 4500 psi tank is really good only for 1600 psi...the difference between 4500 and 2900. At which point if I want to FULLY fill the Gauntlet back up, I have to top off my tank. Is that correct?

[@AirGunScientist]

(Sorry for a long delay in responding, I don't always see these questions). Correct, As one uses the carbon fiber tank to fill the Gauntlet (or any PCP), the pressure goes down in the carbon fiber tank. Eventually it will get so low, that you can't even fill the Gauntlet to 3000 PSI, and then only partial fills. The Great White filled to 4500PSI will fill a Gauntlet 63 times from 2000 PSI to 3000 PSI. Hope that helps, and again, sorry for not seeing your question.

[@Eutimiotorres]

Hey would you recommend using the IORMAN 4500psi High Pressure Composite Cylinder Carbon Fiber

[@heathhalfhill6867]

Hi Joe Love your Informational videos and thank you from helping a lot of us newbies from getting hurt. With that said...I,m trying to turn a 68 inch carbon fiber bottle into a fill source for one of my air guns. I have a modified regulator that allows me to fill the bottle to 4500 psi and a slide check on a stainless steel braided line. The problem that i'm having is that the slide check messes up after about 40 uses and now the valve on the top of the regulator isn't opening when i turn the knob on top of the main valve. It acts like there isn't any air in the bottle. I only want it for one or two fills while out hunting and the lighter weight of it makes it ideal. Do you have any suggestions that will help me be able to use this almost new bottle?

[@AirGunScientist]

We've seen those "Slide-valve bleeders". They fail miserably, that's why we don't make ours like that. We make a Stainless Steel Bleeder, with a knob. Turns and smooth like butter, works 100% forever. Here is one on our SCBA Hose Assemblies. This bleeder has a port for a gauge, but we also make it without a gauge port. www.airtanksforsale.com/scbaassy.jpg

[@hiseminencetheholymacdiarmada]

Can you tell us, or direct us to another video, about how a tanks capacity is labeled and translated across different scales. For instance, I have what is labeled as a 3 liter tank. If you convert liter to cubic feet you get 1L = .0353 cu ft. But my 3 liter tank actually holds something like 23 cu ft. Which doesn’t compute.

[@AirGunScientist]

Liters is the volume of water capable of being contained in the tank i.e. 9 liters Cu In is also the volume of water capable of being contained in the tank. Cu Ft is the volume of COMPRESSED AIR capable of being contained in the tank at a certain pressure (at a given pressure, such as 4500 PSI). 9L ~ 550 Cu in. and 97 Cu Ft is about 550 Cu In. 550 Cu In x (1Cu Ft/12in/12in/12in) x 4500 PSI (Fill pressure) / 14.7 PSI (1 atmosphere) =97.43 Cu Ft

[@kzyt87]

how about the SCBA fire fighter tank use what vale to froster fitting???

[@AirGunScientist]

Yes, when you can find them and they are not out of date. You can use either our SCBA Hose Assembly or convert it with our TJ3 Slo-Flo valve

[@jefbretschneider1607]

Hi Joe, Thanks for the video. You did not specify what size the third (smallest tank) on the table was. I'm guessing; was it a 3 Liter or 30 CF tank?

[@AirGunScientist]

It is 114 Cu In (about 20 Cu Ft or 1.87 Liter

Thank you so very much for that compliment.

[@dkh374]

so what's the difference between a scuba tank and a welding tank? Can't a welding tank for Co2 be used? They are on eBay for $62

[@AirGunScientist]

Carbon Fiber tanks are rated 4,500 PSI SCUBA are rated 3,000 PSI CO2 Tanks hold 800-1,200 PSI of CO2 (Max rating for tank is 1,800 PSI) I would never recommend a CO2 tank, as it is not rated even close to use in a PCP airgun. Also, supply companies will only fill a tank with what a gas that is supposed to go into that tank. Ex, the wouldn't fill an Oxygen tank witih CO2 or propane, even though it could hold the pressure, for obvious reasons. And there are laws that prevent these accidents.

[@airgunspasion5158]

And we also have the much needed Alpha Moisture Filter to go with that AV Compressor (and our Carette Compressor, and the Shoebox Compressor, and the Omega........) ;-) We've got an Alpha Moisture filter fit any compressor.

[@jimbert50]

How long will a tank hold its air under pressure? More quantitatively, at what rate do they lose pressure? It's probably not a linear function. How long before they go from 4500 psi to say, 3500 psi?

[@AirGunScientist]

It should hold pressure indefinitely. I.e. no loss of pressure over time.

[@magnumjgjg]

if you have pressure loss over time, it means your tank is leaking, and you should stop using it immediately, and bring it to a shop to inspect it, and find why it is losing pressure

[@davidmoran7827]

Nothing holds pressure "indefinitely" and EVERYTHING leaks to some degree. With that said, the leak in the tank may be so minute as to not really be noticeable and perhaps even last for years but......

Can i use nitrogen for fill my 4500psi scuba? can be used this nitrogen for my marauder?

I've wanted to get into the airgun sport for more than 5 years and have hesitated because I don't want to invest in a $2K compressor for tank refill and have not been able to find anywhere in the Atlanta area to refill to 4500psi. Any suggestions as to where to look? We are not in an area that promotes diving like the Cali west coast. Thanks.

[@estebancamachomartinez724]

look for the firefighters in your area, they carry this types of compressors and can fill your tank in no time, the problem is getting them to actually do it. Best advise is to approach in a open, friendly manner and explain them what you'd planning to do.

So if I get an Umarex Gauntlet for $300.00,the tank to fill it will be $500.00 to $700.00.I guess PCP is for those with money to burn.

[@AirGunScientist]

The air tanks are the most expensive part when purchasing an entry level PCP airgun. Once you pay for the tank, all you are buying is pellets. You can probably hunt with a .22 LR, most things that you can with a pellet gun, but not always, and it's a completely different hobby. No "Hobby" is cheap. Photography, Amateur Radio, Antique Cars, etc.. Best to you. Hope that helps.

[@blessedman8422]

You might not get a 3000psi fill with the scuba tank but you will get more fills from the scuba tank than say a 90cubic inch 4500psi tank, just based on volume alone. There's more air in a scuba tank maybe not more pressure but more volume. you will get more 2900 psi fills from a 90cubic ft scuba tank. Atleast i do

[@elonmust7470]

Who would spend all that money just to have to rely on someone else to fill the tanks????? I'm buying a tank so I can fill it by myself. Why none of you show people how to do that, who knows?

[@AirGunScientist]

The intent of the video was to show the various TYPES of tanks. I wasn't trying to peddle our compressors, just inform people.

[@alinm3634]

Mr. Scientist. I like all you videos, but you really screwed up on this one. You are misinformed. I'm a diver and I use my steel 3,500 PSI scuba tanks to fill my air gun all the time. It takes over 100 fills of my .25 Marauder, from one full tank until the pressure drops below 2800 PSI, and I would probably get a few hundred more fills if I would use it down to 2500 PSI, but I never tried it. It only cost $6 to fill the tank back up. And there are plenty of dive shops around. Yes they are heavy tanks but you don't need to carry it with you when you go hunting, you get 30 shots with a full gun. The dive compressors are very expensive because they need to fill the tanks with clean and DRY air, and that is the best for the air gun. When a pump is used or a cheap compressor, the steel reservoir from the airgun will rust out in a few years because of all the moisture pumped in with the air. The aluminum scuba tank you are showing is limited to 300 PSI, but even that one will give you plenty of fills before the pressure is too low.

[@mcnultypride]

Where can i buy a good tank for refilling my pcp?

[@AirGunScientist]

If you thin you are getting 100 fills into a Marauder, I guarantee your gauge on your Marauder is reading high (giving you a false impression that you are actually filling to 3000, when you are not.). I've seen this many dozens of times. I'm not going to argue simple physics/math. If you get "over" 100 fills, good for you (But you're getting much less than 35 shots in .25 cal Marauder).

looks like someone forgot to do some editing :D at 7:35 you start explaining how it works, and show yourself overfilling a maurader that you probably have sold by now, and then at 10:00 you stumble a bit, and then seem to start over from the beginning at 10:10. no harm done, i just thought it was funny watching what is essentially the blooper reel while it was playing :P

[@AirGunScientist]

I think you need to review the video. I clearly only fill it to 3000 PSI. Look at the gauge in the picture. Making unfounded/false accusations could hurt a good reputation. Fortunately, most that watch my channel know better. Also, stating that I would sell such a damaged piece is also quite accusatory. Not cool, not cool at all when you don't know the facts.
