Method Exit bag and inert gas megathread

[Tommen Baratheon]

Hi!



hmm I did some research myself and it does not seem to be a problem. 200 bar = 3000 psi and my regulator can max handle 200 bar.

Got my EEBD hood and regulator and nitrogen. Tested the regulator for leaks and no leaks. I am going to test the purity of the N one of these days so hope that it is good.

The supplier said that 15 LPM should do the work if hood is prefilled. Should take half a minute to prefill it at 15LPM.
See a lot of comments that people do 25LPM with the EEBD hood. Any evidence that 25LPM is better? One worry I have with putting it on a higher LPM (like 25) is that hood comes off after couple of minutes.

Does also anybody know how you can test if your regulator is indeed a nitrogen and not a argon one? Got mine from the company who's owner is now is prison, so too speak.

PPH is clear on this:

Exit bag = 15 l/min.
EEBD Hood = 25 l/min.

There's a simple reason for this. If you're using the bag, then it's already filled with gas when you put it on and take your first breath.

Not so in case of an EEBD. These are not already filled with gas when you put them on. You need to hold your breath until the device is filled with gas before you take your first breath. By increasing l/min. you don't have to hold your breath that long.

I would suggest 25 LPM instead of 15 LPM

Prison? if you're talking about Kenneth Law, then you have nothing to worry about, as all his products are reliable and top notch

In the US, aiming for a nitrogen tank, will this regulator work if it says Oxygen and has a click flowmeter that only goes to 15? The Chinese company's listing had said Nitrogen, 0-25L. Then they sent this one instead. View attachment 116565

My supplier is showing me same one for nitrogen with 0-25lpm setting.
Is this right regulator?

Okay yeah got around 1700 liters so I have enough to go for 25LPM so I am going for that.

Tested the nitrogen with the O2 meter and it gave 99,5% purity so I quess that is good (is it?)

The only little worry I have is that my EEBD hood does not really inflate when I put the nitrogen on. I tested it for leaks with soapy water and felt if there is any nitrogen coming from somewhere else other than the entrance where you put head in but it does not. Supplier said it should inflate after 30 seconds at 15LPM. Anyone has the same experience?

Yes, it doesn't really inflate totally--I also have about 1700 liters--99.5% Nitrogen purity is fine, anything 99.0% is ok as per Greenberg

Nice! Maybe same supplier then. Did you have a "test" run yourself? I did. Had a oximeter so I could manage it a little bit. I let it came down to 48~60. I felt my heart racing a bit and my vision started to blur and saw a little bit red an green spots/lights. Then pulled off, no pain or discomfort other then heart racing.

That's interesting another use mentioend seeing green/red lights when testing it too. They also mentioned hearing some strange music

You pulled off just in time--Das Nichts, he also saw red/green lights before he passed out--heart racing always happens, I did 6 tests, heart jumps because it wants more oxygen--you had no pain, no discomfort, just like me

The O2 meter shows the % purity of the nitrogen? How does that work? Doesn't sound right.

 

[kudaphillips]

I'm sure they mean that it showed .5% of oxygen and Theyr just deducing that it's showing 99.5% nitrogen

Oximeter shows your oxygen level. I believe at 28 you lose consciousness

Which is the best gas for CTB I'm new to this group so please be kind with me.

 

[kudaphillips]

Which is the best gas for CTB I'm new to this group so please be kind with me.

Helium nitrogen argon . All work, helium and nitorgen are better because they're lighter. Nitrogen easier to obtain 99.9% purity. I've seen a lot of people with issues with helium because of purity .

I read somewhere that helium is the best gas for this purpose.

Yea if you are certain it's 99% or greater . Nitrogen is just as good both are lighter than air and stay in the bag , but helium is way lighter than air which is why it's considered the best , .

 

[exitingtothevoid]

One thing to be careful of: the helium in those balloon helium cylinders that are sold in a lot of stores is almost always mixed with air. Those used to be pure helium and could be used to CTB, but not anymore.

To get pure helium you would have to go to a welding/industrial gases seller, where nitrogen is also available for much lower cost.

Hi friends. trying to rapidly learn everything I can about Nitrogen in a short time, but I struggle with reading and learning disabilities along with double vision so reading is just that much more difficult. That being said I've read the top of the page that @TiredHorse wrote but I'm having trouble figuring out the sizing that we Canadians use.

Does anyone here have the conversions for the Canadian markets (West Coast, BC, Vancouver) so when I call I can not sound to suspicious. It looks like most places that serve NitroBrew needs work in pounds. So 40lb, 60lb bottle. I have no idea if that's enough because I don't know how to work the conversions and there's over a 170 pages here to work though.

TiredHorse suggests a 40cf bottle or no less than 600l but when I look at my local vendors online they all use different measurements and my google searching skills are absolute trash, all I get are ads for US based companies.

That all being said, does anyone know the best place in Vancouver to source my supply of gas for my at home NitroCoffee and NitroGin needs Linde ?
Thanks in advance.

"In the US, a 20 cubic foot (cf) cylinder is the smallest you should use for ctb; a 40cf will allow some margin for flinching, practicing, etc. "A 20cf" and "a 40cf", or "a 20" and "a 40" is nomenclature US welding supply houses will recognize, so asking for either should get you the desired product. A 20cf cylinder is quite small for industrial use; I've had clerks tell me, "well, we have a 40, but we'll need to special order a 20." It's up to you what you do in that situation. Personally, I have a 40cf cylinder. It has allowed me to flinch and abort my attempt three times now, and I don't need to worry about refilling it. I bought my N2 at AirGas, a national company here in the US. They do not demand any sort of professional certification for purchasing inert gas, and no more than the usual forms of ID depending on payment method.

I know nothing of gas cylinders outside the US, so if you are using other than US-typical cylinders, you'll need to call and ask to make sure whatever tank you're contemplating holds 600L of compressed gas. Hopefully knowledgeable forum members will add cylinder sizing information to this knowledge base."

In case anyone is wondering about argon flow meters, I did an experiment today. There was 150bar left in my 8l cylinder which should give 1200l. I set the flow regulator to 25lpm (but after some time I noticed the ball went a bit higher). It took 55 minutes for the cylinder to empty, which means 25lpm indicated on the argon flow meter should be about 21lpm of actual nitrogen flow.

The key takeaway is that the actual nitrogen flow is LESS than the argon flow meter shows. If someone wants to be sure they're getting enough nitrogen, I'd recommend to follow the 70% rule, even though in my case it seems it was over 80%. Nonetheless, better safe than sorry.

Nitrogen regulator click style on the that famous Chinese site (you obviously know which one am talking about) are those good? They are selling at low price but didn't mentioned medical grade anywhere, is that has to be medical grade?

I don't think you're gonna find anyone say not to use any particular regulator . Even the Amazon 20$ ones should be able to work for a single use. If you were a welder buying one we'd tell you hell no get a better one . I haven't seen anyone say anything bad about alibaba click style regulators . Give it a few tests , get some confidence in it .
Even the max dog regulator pph recommends people say is garbage and not worth the money, prob same exact thing as the alibaba ones tbh.
I have several regulators , from cheap 20$ ones to the max dog400$ one. They all work . Big box stores in my area offer a quality regulator for 100$ that welders use and rely on, I have this as well and will prob use it . Not sure what country you're in and how available thy are .

I really appreciate your reply. I am in Canada. How to test that click style nitrogen regulator? Can you pm me with one you have?

 

[OverIt1976]

This is another method I'm thinking about. Do they sell the CO already filled in tanks? I am thinking about using my CPaP mask since it has a hose, and I can block most of the holes. I'm so challenged with industrial things like this. I thought about renting a helium tank from a party store since they are already equipped with regulators.

 

[LJ85]

I'm totally new to this method, so I apologize for my ignorance. In short, I don't understand how this method works. So, on a very basic level, I understand that you stick your head in a big turkey bag with a hose releasing the inert gas, and then tighten the bag with a drawstring. But even if you tighten the drawstring, isn't there still a small opening where oxygen can get in and out of the bag?

 

[Ehloco]

Tried it once. The sound freaked me out.

 

[kudaphillips]

Well there's a couple ways to test .

1. You just proceed with the method as if your going to do it. But don't do the last step (pulling bag down from your forehead ).
2. Get a dummy head , and secure the bag over it at desired tension
3. You could actually do the whole process and begin to inhale the gas and just bail. Some people use a oximeter to watch their o2 levels decrease then pull the bag off.
4. Some people even suggest to run the entire tank until it's empty to ensure th time and functionality of the equipment works. I like this but it's hard enough to go fill up the gas and deal with all that I don't want to . But I have double tanks should be good

Basically I was just saying, test the regulator and make sure it fills up the bag and works and everything. 15 lpm he bag should be pretty full in a minute. 25 lpm about 30 seconds

I have a max dog brewing regulator 300$
an amz argon regulator 20$
Harbor freight argon regulator 100$
Alibaba nitrogen regulator 50$
A genssi argon regulator 30$

All work

You definitely want to read the procedure from gird horse on th first page of th thread. The procedure need to be done correctly m with th right materials

You got the jist, yes. When th gas is flowing at high rate , it creates a positive pressure inside th bag, so much gas is being forced out the bottom, no air can get in. If you experiment , you'll feel pretty comfortable that no air gets in when you feel th gas rushing out the bottom , and feeling what that positive pressure feels like

Привет из России! Хотела сегодня заказать N в баллоне 6,0 (99,9999), мне сказали, что он доставляется только в 40 литровых баллонах. Ужасный. Боюсь брать 5,0 (99 999)
Действительно ли N 6.0 (99.9999) я могу заказать only в баллоне 40 литров
