NItrogen adapter for SCBA use

[rigbone]

I'm in North America. My Nitrogen tank has a CGA 580 outlet connection.

I would like to assemble a SCBA rig using a Draeger mask and regulator, but they are designed to go on tanks with a DIN 477 No. 13 outlet connection.

Are there adapters to convert from CGA 580 to DIN 477 No. 13?

Read the SCBA megathread, it's mentioned there.

What purity was it advertised as? 3.5 (99,95 %) :(

Ah, excellent! I saw GasMonkey's gallery and that is exactly what I am trying to emulate.

Thanks!

Follow-up question,

I have the "Western # 830 Cylinder Adapter CGA-580 To CGA-346" adapter but it converts to A male CGA-346 connection. The pics and specs I have seen of the Draeger regulators look like they require a female connection? Would I just need to find a CGA-346 female to female to put on the end of my CGA-580 To CGA-346 adapter?

EDIT:

Ok, I see in one of the attachments GasMonkey provided, that the SCBA CGA-346 regulator has a female connector. Do all models of PAS Lite regulators that are made to be used with 2216psi use CGA-346? I just want to be sure that the one I ordered does (Draeger PAS Lite - 2216, DRAEGER-3358743)

Looking at the pics of PAS Lite models sold by US vendors , The tank connector doesn't look like the one in GassMonkey's illustration. Below is a pic from a PAS Lite model (3358743) from a US vendor's site (the one I ordered), and a pic of the connector in GasMonkey's illustration. The the 3358743 certainly looks like it's male, albeit a very elaborate one.

Do you know what the connection designation is for this regulator? Ive seen them before, but other ones I have seen are the cga-346 or 347 type.

From the manuf website, the input pressure is 2216 (cga-346) or 4500 psi (cga-347)
Output pressure from regulator: 87-130 psi
LDV output flow: >400 L/min (which is surprising, I thought it would be much lower)


This one is the 4500 psi or cga-347 connection. They have the Blue wheel. (The cga-346 has the Black wheel)
But the cga-347 will work with a cga-580 adapter. There is another one other than the one mentioned that will work.
You can find it on the big A store. Its a scuba adapter for a cga-580 with 1/4 npt threads.
(DM I can send a link)

If you're referring to the connector in the pic in my last post, Idk what the designation is on that. It maybe a cga-346 that's missing the gnarled wheel around it. My PSA Lite came with the black knurled wheel around the cga-346 connector as shown in the attached pic.

Yes the black wheel kind is the cga-346 variety. Your system is the PN 4046190 model correct?
Cga 346 & 347 have the same threads...except the 347 is slightly longer.

I know that brass adapter has a small hole in the thread part that connects to the scba reducer.
Did you seal that hole up or leave it like it is?

 

[rigbone]

Correct, my model is 4046190.

Good catch on the hole in the adapter. I didn't even see that. I left it alone and didn't notice any leaks when everything is hooked up and the tank is opened up.

The CGA-347 connection is used by the high pressure (4000 psi) scba system (hence the blue wheel at the regulator/reducer part).
There is an adapter for this as well. Its a two piece rather than the one that the cga-346 variety can use. (The 346 has the black wheel)
