This Tank?

Would this tank work for Benjamin Marauder? It's 3000 PSI, 207 bar. 77 cu ft 150.00

"mrjohns"I am just trying to find a tank that will last at least 1500 shots with a Marauder. I don't know anything about PCP air rifles and what they require. But i'm trying to learn.
Not sure what caliber mrod you have? Or what your string looks like?
That will be just as much of a factor as how big your tank is.

Im getting 32 shots now on a fill (soon to be 40 regulated shots on .25 fill).
My SCBA cylinder can refill my armada 55 times (or more).
40 x 55 = 2200 shots per scba fill (or more).
 
According to AoA fill chart these are the #'s 77 cu/ft tank filled to 3000 psi filling gun to 2500 then shooting down to 1500 you will get 24.2 fills*( I believe the air tube is 215 cc) In reality you will get less fills because air is lost in the hose each time. An 88cu/ft carbon fiber tank filled to 4500 shooting the same pressures will yield 75.7 fills. Typically the scuba yoke is around 120.00 either tank requires a gauge and fill. All but one scuba shop used the paintball adapter for the carbon fiber fill. Paint ball shops, Fire Depts are also an option. Those in the know could better explain the shot count for the .177 I got 16 from a .25 and under 30 from a .22 both shooting hot and heavy. using 3000 psi I think you'll find you reach a crossover point where the added cost out weighs the additional fills and traveling.
 
"mrjohns"I talked to the scuba shop where I would get fills and they said they could only fill to 3300 psi. Is that enough? If you bought a 4500 PSI tank, they couldn't fill it. The closes shop that could fill to 4500 is close to Memphis. That's a 5 hour drive for me . I'm trying to find a place in Little Rock, but haven't yet.
Did you check with paintball shops? They usually have high pressure compressors and cascade tanks. Also, since their air is not breath graded it should be cheaper. I would also check with some local fire departments and see if they will fill a tank for you. I found one that filled my tank for free. I have Scott tanks, the same as the department so they had no problem filling it. But it took a while to find one and I got a lot of "no we can't do that" answers too.
 
Another option is that you can try to rent a 6000 psi nitrogen tank from a welding shop. Prices range depends on where you get one. The cylinder I rent cost me $8 per month and $44 to refill/exchange for full tank. Parts to build a fill assembly cost me about $60-70. I'm lucky in that I'm also close to a paintball shop and just use the nitrogen tank for when the paintball shop is low on air pressure.
 
a scuba shop close to me has used and new old stock scba tanks for sale for about 60 bucks. They look to be about the size of a Joe Tigershark. Some of them have 9 to 10 years left. They would need a valve assembly. If anyone is intrested google Scuba Ventures in Shreveport Louisiana and give them a call. If they wont ship it then pm me.....they are right down the road from me.....I could pick one up for somebody and ship it to you.

Just got back from scuba ventures to get my great white filled. The guy that owns the place said people started calling from all over the U.S. out of the blue to buy up those scba tanks. He sold all 25 tanks in like 2 or 3 days. He even said some people got impatient one day because his card machine was down lol!!! He thanked me and gave me a free refill.....said he made some money selling those 25 tanks. Post up here if you bought one. Makes me feel good knowing I helped quite a few people out.
 
When you buy a tank I was told get one for 4500 psi and 65 cu ft, here is a example on ebay. Tanks have a life of 15 years and some need to be hydro tested when you buy them. So if a guy is selling a tank that was built in 2006 for example, add 15 years to that and that will be the year the tank will get scraped.in the year of 2021. I keep checking ebay and I have a guy I contacted for you already to see what he has, as I bought mine for a 100 bucks shipped with a 5 year life. if you live near a dive shop go there and ask them if they have any tanks

You can always try to use a hand pump. I did it a few times and then I was convinced I needed a air tank

You will also need the gauges and I read that Joe B has the best ones, so he may be able to hook you up. he has a banner at the bottom of the forum

This is a very addicting hobby, I am in it since May and I have bought several guns already so I have the sickness.. Good Luck to you


30 minute cylinder = 45 cu ft.
45 minute cylinder = 66 cu ft.
60 minute cylinder = 88 cu ft

You don't have to scrap a tank after 15 years. That's a DOT regulation that affects firefighting use. No company will hydro test or fill it after 15 years but if you have your own compressor or nitrogen set-up you can continue using the tanks. The tank in the link you provided have a non-standard valve so it will not work without a new valve. If you have a tank by MSA, Surviveair, Scott, Drager or another popular brand with a CGA347 valve connection it's fairly easy to buy parts and build a fill assembly yourself.

I understand the part about the tank, just a error on my part but he would need to know someone who would do it for him after the 15 year period has expired




What do you need to fill from compressor to scuba tank. I have a set of Joes B fill now, with a whip.. Is this what you are talking about?
