EEBD kit + Nitrogen

[Shunya]

Instead of the head cover being fitted to the oxygen tank it comes with, would it be possible to connect it to the nitrogen tank? Building a setup from scratch is so intimidating. Please, advise

 

[Shunya]

Or would something like this be good enough but with Nitrogen? If I were to do this in my bedroom, the gas that escapes, will it cause harm to anyone outside?

As long it attaches to the nitrogen bottle with the same connection as the oxygen bottle. Otherwise you'll need to make an adapter or change the connection on the hose.

The EEBD hood is an effective option. Depending on the model it may have an exhale valve to vent your CO2.

You might struggle finding fittings to connect the hood to the pipe from your cylinder; if so you can cut the fitting off and join the pipes with a suitable double barb. Widely available on a certain auction website.

Thank you both for the advice. I live in Indonesia where such things would be very hard to find. Instead of looking for adapters and using any special hood, would a diy exit bag like in the illustration do? If any gas escapes, will it harm anyone outside of my bedroom?

Would you guys mind checking out the two images of the nitrogen gas tanks attached in my post - which one would be adequate, how many liters? Is there anything to lookout for when buying the gas tank and regulator?

Is there any specific information I need to know? I read something about pressurized tanks being like missiles?

 

[Yaffle]

Many DIY hoods are made from oven cleaner kits. The huge bags that the oven trays fit in.

Nitrogen cylinder with flow meter rather than pressure regulator so you can set the flow to 15 litres per minute. In the UK an Argon flow meter fits a Nitrogen cylinder and the calculations are easy to adjust the flow.

Hope this helps a bit

Thank you so much. Will save this into my notes. Will look at the nitrogen tanks (they have different specifications I don't quite understand as yet) available and if I have more questions, please, I hope you won't mind my picking your brain

You could buy that hood in the pic and just cut the hose where it connects to the air cylinder. But it's cheaper to just buy an EEBD hood with just a hose attached (no air tank). You can get cheap ones on Alibaba.

You could use an exit bag as a cheaper method if you wanted.

The nitrogen cylinder is in the first pic above says 0.3 metres cubed, which is 300 litres of compressed nitrogen. If you use a flowrate on the regulator of 15 litres per minute (LPM) of gas, that gives you roughly 20 minutes worth of gas (300 ÷15). The PPH says that death occurs in 5-10 mins.

In the 2nd pic, the cylinder has 2000 litres(2 metres cubed) of compressed nitrogen, so if you use a flowrate of 25 litres per minute, that will give you 80 mins worth of gas. Way more than you need.

I can't tell from the pic whether the guages on the regulator read the flow of gas( litres per minute (LPM) or cubic foot per hour (CFH)). As opposed to just the pressure(in p.s.i. and bar). You need a regulator with a flowmeter, like this one:


You then just need an adjustable wrench to tighten the regulator to the cylinder valve.
The regulators usually come with a hose barb like this:

You attach it to the regulator, leaving you with this:


Then, using a sharp knife/utility knife, cut the connector off the end of the hose of whatever hood you get, and slide the end of the hose through a hose clamp. Then attach the end of the hood hose to the regulator barb, and slide up the hose clamp, tightening it using a flat-head screwdriver.
Here's an example of @k1w1's hose attached to a regulator barb:





If the hood hose isn't long enough, and you had an extra hose like that one in the second pic of yours above, you could extend the hose. Just cut the connector off the hood hose, and attach the end to a double-sided hose barb connector, using a hose clamp. Attach the other hose(the one going to the regulator), to the other side of the connector.

the extension hose and brass fittings are available at hardware/welding shops & are usually 1/4 inch to match the hose. Dont buy the hood AND the tank, just ask the supplier to sell you the hood with hose attached. This is nothing new as they do it plenty. Msg if you need more info.

For the regulator, I was looking online and there's many kinds. Does it have to be for carbon dioxide like in your image or specifically nitrogen, will one for argon do? Sorry I'm dumb .

I found these locally
CO2

Argon

Sorry, I uploaded the wrong pic, I shouldn't have uploaded a CO2 regulator. Try and get a regulator that matches your gas (e.g. nitrogen regulator for nitrogen gas), but if you can't, then that argon regulator is fine ( I have an argon regulator with a nitrogen cylinder). If you buy the argon regulator with nitrogen, you have to do a conversion, given that the flowmeter is set for argon. Just set the regulator to 20 litres per minute (LPM); that LPM in argon gives ~ 25 LPM nitrogen, which is fine.

Yeah, if you're buying a hood, get one like that, without the air cylinder.

My hood hose is 1 metre in length. Given that I'll probably be having my nitrogen cylinder directly beside an armchair, with my body strapped to the chair, that hose length is fine for me.
If you're having the cylinder right beside where you're sitting or lying, 1 metre or longer is fine. If you want a distance between yourself and the cylinder for whatever reason, you'll need a longer hose/ or to extend the hose.

To see how I hooked up my hood to a regulator and cylinder, it's here.

Hello. For the hood, the seller has said that the length of the hose 71cms. Is that enough? Would it be ok if I were to lie down and have the tank lay beside me (I have a big bed).

Is this regulator ok


would it be possible to connect the hose of this hood directly to that?

View attachment 124423

Yes, that regulator is fine to use, as long as you are buying it from the same country/region where you are buying your gas cylinder, so that the regulator connection definitely fits the cylinder.
(if it's from a different country/region to where you're buying the gas cylinder, make sure the regulator connection, that goes into the cylinder, fits the cylinder connection. Because different regions have different types of connection. e.g. in the U.S. the connections for nitrogen/argon are called CGA 580, so a CGA 580 gas regulator will only fit a CGA580 cylinder connection. In the UK it's a different connection. Buying the cylinder and regulator from the same country/region will guarantee the right connections. ).

Someone here before posted that they bought a hood that had a hose of 70cm length, and it wasn't long enough. But they said they would try and make it work by keeping the cylinder very close to the hood. It might be too short, but you could buy it and try it out, you could always extend it. You would need a 2nd hose of similar diameter to that hood hose to extend it longer. If that hood is very cheap, it might be easier for you to just buy a 2nd hood like that and just cut the hose off it altogether, and attach it to the other hood hose. (how to do that is shown in a previous response to you.).

But ideally get a hood with a long enough hose.

Yeah, you can attach the hood hose directly to that regulator. You just cut off the hose connector (the silver metal thing) from the end of the hood hose.

Then attach the hose to the regulator barb using a hose clamp, like in the pics I put in a previous post above.

It is advised to be upright when using the hood. I think it's to allow any CO2 you exhale into the hood to go out the bottom of the hood easier. Plus I think it allows the CO2 to be exhaled out an exhalation valve at the front of the hood easier. Some people have used reclining chairs, which allows them to lie, but have their head slightly upright. See the inert gas setup gallery, here.
However, some people planned to lie on their bed, with their head slightly reclined, with the cylinder beside their bed.

Plus, companies say to store gas cylinders upright. Anyway, I'm not sure it would be a good idea to have a cylinder in bed beside you; could you be certain you could avoid it rolling out of the bed when you're unconscious, and potentially pulling at the hose?( If your arm twitches when you're unconscious or whatever).
When buying the inert gas cylinder, most people probably take the seller at their word that the gas is 100% purity, if you feel you need to test it, use an oxygen sensor or oximeter. This is from the PPH:

Thank you so much for everything! Theyre Both sold locally, yes. I'll ask the seller if the regulator connection will fit the cylinder as it's both sold in the same store. I'll also look into extending the length of the hose. Will check if they have the supplies needed for it.






1m3 = 1000 litres of compressed nitrogen
Flowrate of 25 liters per minute. Set to 20 for the argon regulator above.
1000 : 25 = 40 minutes of gas. Is that enough?

How many liters of gas does your tank hold? The only other tank I found is 6m3 in volume, which I suppose would be too much?

Sorry for my slow response. I've been very ill and haven't come online. One night it felt like I was going to die. Forced myself awake to write a note thinking I won't wake up in the morning but sadly, here I am.

Again, so grateful for everything. (And pardon my poor English) =)

Anyone, help please? How many minutes, how many liters would be adequate?

I hope someone sees this. Is "Falling slowly" ok? Is he at peace, atleast?

The 1000 litres of nitrogen is plenty enough.
Yes, probably best to set it to 20lpm on the Argon flowmeter, which like you say gives about 25lpm of nitrogen.
40 mins of gas is fine, PPH says death in 5-10 mins with nitrogen.

I've found that most here say the flow rate should be 15 liters per minute. Is there a difference between setting it to 25 instead of 15lpm?

In the PPeH 15lpm is recommended for nitrogen with an exit bag. But when they were testing nitrogen with a hood/helmet, they recommended 25lpm.

I would go with 25lpm nitrogen (20 LPM on the argon regulator flowmeter) for a hood. You have plenty of gas.
