O2 regulators

[mr x]

Here's a supply company in Canada for cylinders:

Maybe a group buy....?

Ok, made some calls today. Here is what I discovered. Connors diving does not fill O2. Liquide Aire can supply any size medical grade cylinder, from Vitalaire, but only under rental. No direct sale. They do the breweries this way. The guy at LA said to try Vitalaire for a direct sale of a tank. They only do medical grade fills in nfld, and maybe moncton. He gave me a contact - Mike Avery @ 1-888-629-0202. I might get a chance to call him later this week. It's too hard to talk on the phone at work. If anyone would like to call in the meantime, be my guest.

Here's what I use....





Sterile filter...


An O2 tank the size of a 40 lb CO2 tank lasts through ~ 40 x 5 HL batches at the Hart & Thistle

BTW, my regulators came.

NASH, looks like you get your gas from Praxair. Can you give us the details (rent/buy, cost,etc)?
I will contact the other dive shops today for more info.

Chalmers, there's some Praxair prices further up on this page.

Thanks, I had missed that.

From Torpedo Rays in Dartmouth:
Full emergency O2 recovery setup is $1200. So that is no good.
They will do an O2 cleaning on an existing tank for $40, and on a regulator for $35. And to fill a tank is $1/cubic foot. A knee high tank is probably 60cu.ft., so not as cheap as Praxair.
From what we're getting back, Praxair is the way to go, unless we can get some used tanks at a reasonable price and do out own thing. Hopefully the decommissioned ones will work.

I had every intention of jumping on the eBay auction X had posted (6 bottles for $100), but forgot about it till right now. And it has ended. I don't suppose one of us got it?

[RubberToe]

Have we found a place that will fill a medical style tank, and without a prescription? I imagine medical O2 is more expensive too. I got the vibe that Praxair didn't fill medical tanks but didn't ask directly.

[mr x]

I believe it is a matter of the cga type that dictates whether or not they will fill it. Medical/scuba(?) look to be cga-870. I 'think' LA will do it, but I need one to take in to be sure. Getting one from Larry on Sat. I will buy a new type E which looks to be 24 ft3 most likely if the dive shop or anybody else will fill it at a reasonable price.

[mr x]

Btw, my online research says the type E is 24'' high. If true, $1 ft3 sounds damn good to me. Do they hydo certify the tanks? You guys can try vitalaire for a direct sale as I mentioned above. I can't call from work, it's too loud.

[mr x]

I didn't buy the ebay gear as i was looking into a black hole regarding hydro date and refill info. Although they may still be able to be bought. She did email me back, but didn't understand what to look for on the tanks.

[mr x]

Just looked the Torpedo Rays website. They seem like the people to deal with. They do the hydro tests there.

[chalmers]

Just got back from Diver's World, another dive shop (in the same building as Don Brenton's).
They have medical O2 kits for $300 (either D or E size, which means 15 or 24 cu.ft, 425 or 680 litres), with first fill included. They will also do hydro tests and the like. I forgot to get the fill price, but suspect it won't be too far off from Torpedo Ray's. I know the manager pretty well, and he was hinting towards needing an "O2 administrator" course from a SCUBA instruction course if this was going to be a regular thing. Meh.

Forgot to mention, while talking with Torpedo Ray's owner, he mentioned that in NS a prescription is not required for purchasing breathing O2 (whereas it might be in other provinces). I think you knew that, X, but wanted to make sure others did as well. So places have no legitimate reason not fill sell/fill tanks (except being unaware).

I've got o2 administration, and know a few people who can certify others, if people were so inclined. but as long as you don't need it, don't bother, haha.

[mr x]

Sweet CA. I think I'll hit up vitalaire thursday when I'm back in the city, unless somebody would like to try tomorrow with the contact i posted. I did not know that chalmers on the legality, and neither do the vitalaire people i spoke with at the head office. I am getting a better feel for this, and am thinking about buying E sized tanks from the supplier above next week. Thanks for the legwork.

[JohnnyMac]

Let me know when you guys pull the trigger, I'm gonna be in for one of these. Also, let me know if you need a hand with getting the shit in a pile.

[mr x]

Yup, i'll start a thread for anyone who wants in once I'm 100% we are cool on the filling and get some prices.

[Jimmy]

The dive shops just take their tanks to air liquid/praxair to get filled FWIW.

[mr x]

Huh, well there you go, learn something new all the time. I know LA would do it. The sales people they hire that answer the phones are fucking retards. Feel free to link this post to them, lmfao.

[Jimmy]

I guess I should elaborate now that I'm not using my phone. Divers World has "K" bottles that they take to praxair to get filled, not sure if there is a different policy for the smaller cylinders. It's been about 7 years since I've worked there, so all of this may have changed.

[mr x]

OK, vitalaire is a dead end. Starting a GB thread.

[mr x]

The unit we had on Saturday looks to be a size m4, which has 113 litres (4 ft3). I'm going to change out the output side pushlock fitting into swagelok and see how it performs through a stone, they are just standard 1/8" npt. It may be one time use only though, as I'm not sure who would refill this unit. And the hydro is out of date, so it's questionable if it's worth getting retested. Although $45 over 5 years isn't bad if it's easy to get refilled @ $1 ft3....

[mr x]

Ok, here is what I discovered. The two output fittings have a pressure reducing orifice, in addition to the spring loaded closure. So you need the pressure reducing function, but the spring closure drops right out. The problem is the connection. It just happens that 1/4'' tubing fits in really snug, and didn't blow out when I turned it on, but a more secure option would be nice. Maybe ss tubing jb welded in there. The other issue is flow. I have a flow meter to dial in what I want, but no spares. Going to bring this into TRay's on Wednesday to ask about filling/hydro.

[chalmers]

Thanks for doing the legwork, lers and x. Hopefully TRay's has some good news on the test and fill. I'd almost feel better about using all of the existing fittings, and putting some hose over that pin-lock style output. Is JB weld O2 safe?

[mr x]

I'm still using the existing fittings, I just dumped the guts out of it. It won't work with the spring loaded closure mechanism in place (unless we had the proper pinlock mate for it). I need to check on JB weld for O2 safety. The other option would be silver solder/welding a pice of tubing into the fitting. I think they are ss. It might also be possible to chop off the pinlock nozzle and tap it for 1/4'' npt, which would give limitless options...
