Wanted: 300 BAR SCUBA TANK (4350PSI)

[chuvak]

As a general rule, divers in the U.S. don't use these tanks. There are bouyancy issues with the tanks, they're hard to find fills for and they're expensive as heck, not to mention the short lifespan. You'll probably have more luck talking with places that use SCBA, such as fire departments and places that handle hazardous materials.

Hi,
i'm looking for a chapest 300 BAR/4350 PSI (or more) scuba tank.
I'll never use it for breathing.
I need it for refilling my air rifle.
Anybody maybe have some used, but at good condition tank for sale?
I'm located in the EU.
Thanks!

Luxfer makes a fiber wrapped tank that you want. Any good dive shop can get you one

Since I cannot use my EU/South African/Australian certified cylinders here in Canada(no TC stamp...), I have two 7l 300 bar cylinders - Draeger valves. Problem is getting to the EU. Heavy and shipping is going to be expensive.

Out of curiousity, where do you get that thing filled?

If I may answer that...
In the UK, Europe, Southern Africa and a few other areas, 300bar is well known. My Draeger 7l set originally comes from a set that is standard on many fishing vessels. I could legally fill my cylinders at 90% of the scuba shops, a main industrial gas supplier or the fire brigade.
I found the norm over here to be 180-200 bar vs 200, 232 and 300 elsewhere.
The testing facilities that could test to 450 bar were not so abundent!

The "short lifespan" story is a myth. I have seen and used cylinders dated from the early eighties that passed all hydro and visual requirements with flying colours.

Cheers

It's no myth in Canada -- composite cylinders must be condemned at 15 years whether or not they can pass a hydro.

Sorry - some clarification would be in order: I'm talking about steel cylinders, not composite.

actually in the US 300 bar cylinders have a maximum absolute lifetime.. The only 300 bar cylinders allowed in the us are a hoop wrapped al cylinders.. (made by luxfer and they have a whole set of rules with them). They also must be hydrod more often.

300 bar cylinders elsewhere are more commonly steels and should last just like any other cylinder...

Luxfer makes a fiberwrap 300 bar aluminium cylinder

Paintballers regularly use 4500 psi tanks. (5000psi tanks are avalable but uncommon) The most common are 68 cubic in and 88 cubic in. The output is either 800 psi (preset) or adjustable 200-1200 psi.

Try looking at the following web pages for ideas.

I have extensive background in paintball, If I can be of any help please contact me.
