Figuring out the scuba method

[Bengal]

I've read a lot on this board and I'm trying to procure what I need to attempt the inert gas/scuba method.

I have a big ass nitrogen tank so that part is done.

But I'm dealing with a lot of neuroinflammation that impacts my brain and gives me a permanent headache. Figuring out how to get the scuba mask (or a SCBA) to the nitrogen tank just makes it worse.

I live in the US. The tank has a CGA 580 outlet. In Scrooges manual he just has an adapter that goes right in the tank.

Every adapter I see converts to NPT threading instead of the NPS threading that would be necessary. NPS is what scuba equipment uses and it's not interchangeable.

Sorry I'm just very frustrated. What adapter would I use? Basically how the hell do I make this setup bc nothing I'm seeing seems to allow to me get from tank to regulator properly?

If anyone can help thank you

The options for SCBA are 2:

1. Buying the entire kit already done and ready to use (expensive option).

2. Creating your own setup (cheaper option). You need a N₂ pressure regulator for the standard of your region (CGA-580) capable of supplying 7 bar or more, demand valve, mask, and quick coupling adapter to connect the demand valve to the regulator (depending on the thread type/size of your regulator). A more straight forward implementation would be to use the adapter in the cylinder<->regulator connection, the US adapter (CGA-to-DIN) is expensive tho (the EU one is really cheap).

The problem with SCUBA is that most demand valves are Negative Pressure (which is not optimal for CTB) and the SCUBA Positive Pressure gear is expensive (the PP mask+demand valve combos that I have seen were around $1000). I have talked about it on other threads.

Yes I preferred SCBA. Money is not a problem bc I have much more than this will cost and I can't take it with me. The first option would be great.

I clicked on it and just got a picture. How do I get it and is the kit directly compatible with the CGA 580 outlet on my tank to the point I can stop obsessing over this?

I just want peace and trying to do this right is bringing me further from that

 

[Bengal]

Sent you a link to a website that has whole nitrogen kits, or CGa fittings etc

Thank you. I'm probably going to do the SCBA method due to the positive pressure aspect.

I just want to confirm I can buy the EM SCBA full kit it will be compatible with my CGA580 nitrogen tank and I won't need to buy anything else to have my setup.

Thanks to any responders

 

[QuieterTimes]

Hi, could you send me the same link pls?
Thanks

 

[Bengal]

From the Link :
"It bridges a CGA580 (inert) source to a DIN#13 (5/8") connection.

• World's most compact (and only) integrated CGA580-to-DIN#13 adapter
• Fully compatible with DIN connector SCUBA gear

Yes but would that work with the SCBA mask (considering the kit is sold out but the mask is available)?

Sorry. My head just hurts so much from doing this. I either just need a complete list of every single thing I need to recreate that kit or I need to wait for it to be back in stock (I'd prefer not to wait but getting this right is most important).

I should've planned this before condition got so bad. But I thank everyone for helping. I need to rest my head but I'll be back to figure this out

That is all I know about that website and that adapter allows a U.S. CGA580 Nitrogen tank to connect to scuba gear, scuba for diving. I haven't looked into this any further . I guess i have too many methods I'm working on. need to focus on one. But you can email the website owner and I heard they are very helpful and they may give you more guidance to complete a setup. Or maybe others here that have done more research can help.

Edit:
I just wanted that adapter on the EM website to connect a nitrogen tank to a scuba full face diving mask . But @GasMonkey said that the EM website also has other SCBA kits that connect to a U.S. Nitrogen tank

You can send an e-mail to K and ask him how long will take for the restock of the CGA-580 kit, and if it's too long look for other options.

I have sent you a link of another interesting SCBA from an US store which has a huge discount right now.

that adapter allows a U.S. CGA580 Nitrogen tank to connect to scuba gear, scuba for diving.

SCBA uses the same connection (DIN#13), which is the most extended standard for Air cylinders.

 

[GasMonkey]

U.S. Nitrogen tank ---- > that adapter CGA-580 to DIn ---> SCBA kit ?

Yep.

The EM kits don't need adapters tho, they run entirely on N₂ native mode.

 

[GasMonkey]

The EM kits don't use any adapters, the connection to the tank is done with a Medical Nitrogen regulator.

 

[Bengal]

Thank all for your help in my journey here. I'm trying to learn about and understand this stuff but it's foreign to me. And I'm not in a state where learning is easy

You can send an e-mail to K and ask him how long will take for the restock of the CGA-580 kit, and if it's too long look for other options.

I already emailed him.

But I just decided to purchase the 45 minute discussion. As I said. I literally don't care about money in the slightest. My medical bills are $40,000 a year (US healthcare), so this is all nothing in comparison

 

[locked*n*loaded]

My medical bills are $40,000 a year

That should be considered criminal for anyone to have medical bills that high. What an effed-up healthcare system.

I have "great healthcare" too. I was just recently rejected for an expensive anti fungal medication bc the insurance company wanted me to try cheaper options.

My Dr already knows they won't be effective w how bad my intestinal overgrowth is. I also am prone to having a ton of side effects to meds so experimenting is a bad idea.

But the insurance company doesn't care what my Dr thinks is best. That will be $400 a month please

It just all adds up like crazy.

Will you please send a PM to me with both links mentioned above? Thank you.

Were you able to find a positive pressure scuba demand valve? And why is a positive pressure demand valve ideal for CTB rather than a Negative pressure demand valve?

One last question. Does that SCBA lot come with the coupling adapter? Or do I need to buy the adapter separately?

Yep, but I can't post it here, is against forum rules.

why is a positive pressure demand valve ideal for CTB rather than a Negative pressure demand valve?

A Positive Pressure demand valve maintains a Positive Pressure inside the mask of some millibars over ambient pressure, so it's physically impossible for external air to enter the mask (it creates a perfect seal, even if it's not airtight). This is the system used by firefighters and it's the standard for breathing a gas from a cylinder while being completely isolated and protected from the external gas (SCBA).

A Negative Pressure demand valve opens when a Negative Pressure is detected inside the mask, which means that it lacks the protection from the Positive Pressure and the seal is totally dependant on the mask->skin contact surface being airtight. This type of demand valves only exist in SCUBA (no longer manufactured for SCBA, although some old models can be found in the second-hand market). Also since a vacuum needs to be created for the demand valve to open, it will have some degree of inhalation effort, which can be regulated with a rotating wheel in the SCUBA full face masks with integrated demand valves.

Does that SCBA lot come with the coupling adapter? Or do I need to buy the adapter separately?

The SCBA kit that he's talking about (from the Canadian source) doesn't need adapters. It is composed by a medical Nitrogen regulator, a demand valve (with a longer hose than usual, with the adequate connector for the regulator) and a SCBA mask.

If you'd be willing to PM me what you'd recommend for someone looking at SCBA in the US today, I'd greatly appreciate it!

1. Buying the entire kit already done and ready to use (expensive option).

@GasMonkey Is this still an option? I would love to buy everything ready to go. I am having trouble thinking clearly and the details of setting up my own SCBA or SCUBA setup seems really hard

 

[GasMonkey]

Is this still an option?

Nope. The site was taken down and the owner taken into custody with charges of assisting suicide, he's currently on trial.

Darn. I am seeing multiple guides to setting up SCUBA/SCBA. Which would you say is the easiest to follow with simplest steps to acquire and put together the gear? (I'm having trouble thinking clearly and need baby steps).

I'm in the USA if that makes a difference.

 

[GasMonkey]

For SCBA in the US you need a 2216 psi SCBA which has a CGA-346 connector that can be connected to a Nitrogen cylinder using an air-to-nitrogen adapter (CGA-346 to CGA-580). You can either get it new or search in eBay for cheaper equipment (lots of folks have done that to save money). I can't post direct sources here since is against the forum's rules.​

The 4500 and 5500 psi SCBAs won't work because they use a different connection (CGA-347) and there isn't any air-to-nitrogen adapter for that in any shop afaik.​

For SCUBA you would need a DIN regulator and a DIN#13-to-CGA580 adapter.

But unfortunately escMode was the only site selling this adapter in a solid 1-piece implementation.

There are SCUBA shops that sell this adapter in 2 pieces, but stacking 2 adapters in high pressures isn't a great idea.


For the Nitrogen cylinder lately most US members are getting it from AirGas.

@GasMonkey What's the advantage of this method over just ordering a R2D ReBreather lll and nitrogen for about $400 total?

 

[GasMonkey]

Do you mean SCBA? the advantage is a full face mask with positive pressure (perfect seal at all times under any circumstances).

Wow, thank you @GasMonkey that is super helpful!

When I google for "2216 psi SCBA", I can only see for sale SCBAs with a tank and harness. Is it possible to buy just the face mask parts that I need?

 

[bluebus]

Does anyone know if this mask would work? I have a CGA 580 regulator and a CGA 580 to CGA 346 adapter. I am planning on connecting the end of the hose of this mask to the adapter.

 

[GasMonkey]

You can buy the regulator+demand valve and mask separated yeah.​

The CGA580-to-CGA346 adapter is for connecting a 2216psi SCBA regulator to a Nitrogen cylinder, it doesn't have any function for that mask, apples and oranges.

A mask connected to a flow regulator is not viable unless you use a huge flow rate or it has a reservoir bag in the middle (like Non-ReBreather masks) to be able to meet the demands of inhalation. A mask doesn't have enough inner volume to act as a reservoir. SCBA and SCUBA masks work because they are connected to a demand valve that pumps all the gas needed on-demand. Constant flow masks like that are used connected to air pumps at very high flow rates.​

Oh shoot. I have been searching online all day and my head is starting to spin. Is there a certain site that I should be looking on? I live in NY if that helps. Thank you for all your advice and help so far

I'm hoping that one of these might be the right pick
I can't seem to find one that doesn't come with a cylinder as well (which I don't need), and they are all very expensive ($1,200+) which seems bit unreasonable. At the end though I'll pay whatever I have to, it's not like I have anything better to spend it on lol
I am also not sure how to tell which connection they take, it doesn't mention anything about that in any of the "details" section

Wow, thank you @GasMonkey that is super helpful!

Same problem here

This is the only one I could find that actually specifies 2216 psi, but it's almost $3000!
