I've seen people mention this 'do it with chi' video a lot; could you point me to where it is? I've looked around the sticky posts but still haven't managed to find it.
Scroll down a bit on here and you'll find the video:

I found it kinda confusing from the video but they explain how to make an exit bag nicer (in my opinion) in Five Last Acts (2015) which is also linked in the sticky thread. I think from page 107 in Five Last Acts details how to make the exit bag.

If I may ask, what went wrong with attempt 2 & 3?
The second failure was because I lost a rubber washer when dismantling the regulator, causing a gas leak when I opened the valve of the cylinder. The third time, I mistakenly connected the oxygen regulator to the Scuba instead of connecting it to a exit bag, which made it difficult for me to breathe.

Did anyone else get their house searched by the police or FBI and get their products ordered from EscMode taken from them? What ended up happening to you? Was there some legal action that took place or what?

This happened to me and they took my regulator and SCBA mask. I'm afraid they'll come back and search my house to find my 40 cf Nitrogen tank. I don't know how I'd explain that, anyone have any ideas?

Am afraid they'll put it together (regulator, mask, gas tank) and I'll get sent somewhere for having clear intentions of suicide. I don't know maybe I'm over thinking everything. Any advice would be appreciated
I don't know where you live, but it was no problem for me here in the US--They knew I ordered the EEBD Hood and regulator/flowmeter from EscMode, and when I ordered it(last June)--Police in the US are not allowed to enter your home without a warrant--I politely told them that I'm feeling less depressed than last June--They asked me if I wanted to give them my stuff but I said no--They were very nice and said, ok just a wellness check visit

How long does a tank hold its gas? I want to purchase a tank ahead of time so that when my condition deteriorates to the point I can't endure it, I will have a way in place for leaving the pain. But it could be as long as a couple years. If I buy a tank now, will it still have all its gas a couple years down the road or would I probably need to have it refilled? Thank you.

Just starting to build my inert gas kit which will be using N2 gas, Drager PFS 7000 Mask with PSS LDV, Harris Model 25GX Single Stage N2 Regulator. I will modify the LDV hose to attach directly to the output of the regulator.

Regarding N2 sourcing....I'm wondering if calibration gas would work, has anyone has this in their kit? The advantage is they can be shipped full in the US and the tanks are disposable (recyclable) after use (specs below). Buying a tank and having it filled locally isn't a viable option for me.

Nitrogen (N2) 550 Liter Cylinder 99.999% Pure
Tank Size (steel): 4" diameter by 20" height

550 Liter Cylinder (E)
Contents: 550 liters (19.5 cu. ft.)
Pressure: 2200 PSIG
Outlet: CGA 580
Weight: 12.9 lbs
Dimensions: 4"x20"
D.O.T. Specs: E8990 NRC
Disposable tank

That probably won't work. I talked with a guy who tried to implement that type of SCBA setup with an industrial Nitrogen regulator and it didn't work as expected, the regulator wasn't sensitive enough to maintain the proper pressure for the demand valve, so looks like it's not a good idea.

Maybe it could work with a higher quality low output (0-10 bar) pressure regulator but in general looks like those regulators are not made to be so precise with variations of demand (not like SCBA regulators which are incredibly precise) and not made to have zero demand phases (exhalation). The main problem he had was that when he exhaled (0 demand) the regulator started to go crazy pumping too much pressure.

The original idea for such a setup was from Joarga. I don't know if he had the same problem because he never responds to any PMs even tho he is online everyday (looks like he just CBA to answer 😂).​

The Regulator:

A regulator screws on to the cylinder and does two things: 1) it reduces the pressure in the cylinder to a useable level, otherwise the 2000psi tank pressure would just blow the exit bag off your head as soon as you opened the valve, and 2) it controls the rate of gas flow into the exit bag —specifically, it should release it at 15Lpm, which is the minimum adequate to carry away exhaled CO2 and fool your lungs into believing there's enough air.

The good news is that while gas cylinder sizes are not globally standardized, the cylinder valve threads are —and both N2 and Ar cylinders have the same threads (other gasses have different threads), so a regulator that fits on one cylinder will fit equally well on another.

You don't need to worry about being sure to choose a regulator that will reduce the pressure: they all do that. The flowmeter is the critical element of the regulator for our purposes.

Some regulators come with a "click adjust" flowmeter that is very simple, allowing you to dial in 15Lpm without needing to think about it. To the best of my knowledge, these are medical grade regulators; generally very good quality, but often a bit more expensive. Others here may know more about them, and where to acquire them, than I do.

A typical welding regulator will have two gauges: the tank pressure gauge (unimportant to us) and the flowmeter gauge.

A welding regulator's flowmeter gauge will be marked in either cubic feet per hour (Cfh), Lpm, or both. Some welding systems require a fairly low flow of inert gas, much lower than our necessary 15Lpm, and this low flow is most easily measured in Cfh. If you see a gauge marked only in Cfh, it probably will not work for our purpose. Look at the highest Cfh setting on the flowmeter and do the math, to be certain. If the gauge reads in Lpm, a glance should tell you whether the regulator provides the necessary 15Lpm flow.

Harbor Freight Tools offers a cheap CO2/Ar regulator (it also works for N2) with a flowmeter that shows flow in both Cfh and Lpm and goes high enough for our purposes. This is what I have.

The Hose:

The hose needs to be long enough to reach from the gas cylinder beside you, up into the exit bag on your head. I have found it easiest to lead the hose up my back and into the bag at the very back of my neck. It seems to disrupt the fit of the bag less right there.

Some regulators come with a hose that threads directly into the regulator body. Some regulators come with a hose-barb, onto which a length of soft tubing can be pressed. Some regulators come with neither.

For the first situation, just thread the hose into the regulator, tighten it with a wrench, and it's ready.

(Regardless of what type of threaded fitting is used, you do need to wrench-tighten this fitting: a lot of gas can leak out at this connection. If it is a brass fitting, you should not need teflon tape on the threads; the soft metal deforms enough when tightened to provide an adequately gas-tight connection.)

For the second situation, take the hose-barb to a hardware / home improvement store and purchase tubing that fits onto the barb. Once home from the hardware store, thread the barb into the regulator body, tighten with a wrench, and press the tube onto the barb. It should be a snug fit; if you're worried it's too loose, use a small hose clamp / jubilee clip to secure it in place. If it's a little too tight to get the hose into place, soak the end of the tube in very hot water to soften it and press it onto the barb. I used clear vinyl tubing. Aquarium tubing should work. Surgical tubing may not; I don't know for sure.

For the third situation, you'll need a hose-barb fitting (typically brass) that threads into the regulator body. Take the entire regulator to the hardware store and ask someone to help you fit it with a hose barb. Then proceed as for the second situation.

Cover story: as with purchasing the gas cylinder, you're using N2 for brewing, or Ar for filling partial paint cans. Why Ar? because it's heavier than air and settles down onto the paint surface inside the can. For extra confidence that they won't ask inconvenient questions, you're doing it for your father, or your brother, and you don't know why they want it for their paint locker, they just said to get a hose barb and six feet of tubing…

The Exit Bag:

There are several videos on YouTube detailing construction of exit bags. I strongly recommend watching them. That's how I learned.

The short version of what you want is a turkey roasting bag —available in the supermarket, in with the zip-locks and cling wrap— with an elastic drawcord worked into a turned hem, and a cord-lock to adjust the drawcord's tension.

I used 3/8" elastic cord. I purchased both it and the cord lock at a sewing and crafts store (JoAnn's).

To construct the turned hem you'll need micropore (surgical) tape, available at a pharmacy in the first aid section. It's the right tape to use because it will reliably stick to the material of the bag itself. Sometimes it isn't labeled as "micropore." Ask a clerk if you can't find it.

Cover story: you were asked to re-stock the family first aid kit with micropore tape and you don't recognize any of the brands available.

Using an elastic drawcord is important: it needs to fit snugly around your neck, but not seal tightly. It must still be flexible enough for the flow of inert gas, lightly pressurizing the exit bag, to push past the elastic and flush away the CO2 you're exhaling. Don't use a non-elastic drawcord or do something like duct tape the bag to your neck; you don't want to create a seal, just a restriction.
Can I send you a pm?

Finally managed to make it correctly.. it's so simple but my dumb ass couldn't work it out for the longest time 🤣 video easier to follow than diagrams

What about using an adapter so I can use a Drager regulator? I've done some preliminary searching, however I am not familar enough with types of fittings so I am not finding the part, however I've alread seen tons of adapters so I would imagine one would exist, if not I could have one made.

Correct me if I am wrong, but for US tank with CGA-580 I would need male CGA-580 to female DIN#13 G5/8" maybe this: https://proteushop.com/en/assembled-adapters/92338-adapter-cga-580-male-to-din-g5-8-230b-female.html

There are CGA-580 to CGA-346 adapters so if you find a CGA-346 SCBA regulator, you could connect it to a Nitrogen cylinder.​

male CGA-580 to female DIN#13 G5/8"
The US decided not to follow the World's standard connection for Air (G5/8") and created their own standard (CGA-346 & CGA-347), so you can't use that adapter. Most US SCBAs nowadays are CGA-347, but maybe you can find one of the old CGA-346 models.​

Or this: https://www.alibaba.com/product-detail/brass-CGA580-transform-G5-8-Connector_1600134409989.html

I use the metric system quite a bit because imperial sucks, but not that familiar with DIN threads, pitch etc. Totally forgot to use my other brain Chat GPT since mine is not working well enough. From out AI overlord:

"DIN G5/8 is a specific type of connector used with gas cylinders, primarily in high-pressure applications like scuba diving. DIN stands for Deutsches Institut für Normung, which is the German Institute for Standardization. They are responsible for developing and maintaining various technical standards, including those for gas cylinder connectors.

The G5/8 designation refers to the thread size and pitch of the connector. In this case, it has a 5/8 inch diameter thread with a pitch of 14 threads per inch. This is one of the most common types of high-pressure connectors used in diving equipment, especially in Europe.

DIN connectors are known for their reliability and robustness, as they are designed to handle high-pressure gases. They consist of an O-ring seal that provides a secure and leak-proof connection between the cylinder valve and the regulator. This connection is typically rated for pressures up to 300 bar (4351 psi), making it suitable for use with high-pressure gas cylinders used in scuba diving and other high-pressure applications."
There are CGA-580 to CGA-346 adapters so if you find a CGA-346 SCBA regulator, you could connect it to a Nitrogen cylinder.


The US decided not to follow the World's standard connection for Air (G5/8") and created their own standard (CGA-346 & CGA-347), so you can't use that adapter. Most US SCBAs nowadays are CGA-347, but maybe you can find one of the old CGA-346 models.​

I understand about the US standard, we suck at that which is why we are on imperial still. To be clear I don't want a US SCBA which is why I would need an adapter which I think I've found.

So the tank has a CGA-580 and I need to connect G5/8 to it so I am not sure why an adapter wouldn't work.

I see, but again I don't want a US made SCBA. I don't see anything special about that "air-to-nitrogen adapter" it's just a male CGA-580 to male CGA-346. So what I need is an adapter with male CGA-580 to male G5/8-14 which will allow a connection to the Drager regulator. I just need to find one or have one made.

So you want to buy an EU SCBA which has a (DIN#13 G5/8" connection) and import it to the US? That would require an air-to-nitrogen adapter with a DIN300 female on one side and CGA-580 male on the other side, like this one:​
DIN13 to CGA580 adapter
Unfortunately and the only supplier of this adapter was escMode (which has been taken down by the Police), what a bummer! :blarg:

I don't need an EU version, but it would have been easier than the mods required for a CGA-347 SCBA which will require fitting high pressure hoses to the precision regulator I found, which appears to be the same as what @DOGMA67 is using in their kit. Additionally connecting a hose to N2 tank using a male CGA-580 to 1/4" NPT male on the N2 tank to a hose which connects to the regulator via a CGA-347 female with 1/4"NPT male connector. This will allow me to use the Drager mask and LDV in combination with a non-Drager regulator, hopefully the SCUBA regulator will work.

I am posting this really late so it may not be perfect, I will review tomorrow and check

DOGMA67 didn't use any high pressure hoses, he just connected a SCBA regulator to a Nitrogen cylinder using an air-to-nitrogen adapter, like Scrooge, SlovakGuy, LetzteAusfahrt, Wunderkind, ertn and me.​

As far as I know there is no CGA-580 to CGA-367 adapter, @Bengal spent a lot of time looking for one and never found any, I don't know if he also searched for hose-type adapters. He ended up CTBing with the escMode SCBA instead.​

I wrote this way too late so as I thought it didn't end up making sense, but in a nutshell I am going to use the same regulator as @DOGMA67 and will create an adapter using CGA-580 to 1/4" NPT male fitting which will connect to a CGA-347 female with 1/4" NPT male fitting. Connecting these two fittings will create the adapter. Once I have the adapter I will be able to connect the CGA-347 male on the regulator to the female end of the adapter. I am in the early stages and it will probably be weeks or possibly months before I am done. If successful I won't be creating any how-to guides for obvious reasons, however I will post in the inert gas setup gallery thread you created if it works.

Both of those let you regulate the output pressure to a lower amount of pressure which is not what you want.
You want a regulator where you can set liters per minute.
