Nitro/Compressed Air Quality

[LaW]

Scuba shops are your best bet when it comes to fills if there are no local fields around. In order to get 4500 the compressors alone cost a lot and it's hard to find places that will fill that high. You could get your own setup like with scuba tank and fill adaptor etc with a used tank will run you about 200.. you'll get about 2 3000psi or close to that fills and the rest will be less and less. 4500 is expensive hehe you know what i've been responding to posts and I'm like so out of it that i don't remember what i'm talking about so my posts sound weird... i need sleep or something

Yes you can find fill stations for 6000 psi cylinders they are very expensive. But you say your Gas shop will not stock them anyway.

So SCUBA is probably your best bet and live with the 3000 psi fills in your 4500 psi tank. You can find 4500 psi SCUBA'a they are Steel not aluminum and expensive and heavy as heck. And many SCUBA shops cannot fill past 3000 psi anyway.

SO I recommend a 80 cubic foot - 3300psi Aluminum SCUBA with a SCUBA Fill Station,. Should all be obtainable new for about $200 total or you can look for used and save a few bucks.

Read up on the cascading of more than one of them, The advantages of the 3300 over the 3000 scuba and all about hydro dating and VIP inspections and such. It's all here already as I said.

Are you talking about setting up your own fill station?

If so then I have to try and talk you out of it unless you are a qualified airsmith. Those things are bombs and I have lost tow friends so far to faulty tanks rupturing on them while diving. Also, a diving stope near my house recently closed its doors after their fill station blew. One guy lost half of his left hand and a 3 year old kid in the store almost got her head taken off.

Please be careful with fill stations.

If you are just talking about getting you tanks filled by an air supply facility then use them, you'll just have to live with the lower pressure.
