Hey, what's up guys, Chris here with cry effects. Welcome to the croft. YouTube channel in today's video, we're going to be talking about how long can a co2 tank. Last co2 tank, sizes, co2 cylinder sizes. We got a chart for you on this video as well, that's going to cover all of that.
But before we get started if you like our channel, if you like our videos, of course, hit that subscribe button. And we welcome you so let's get into this. You have a question. And your question is, how long can my co2 tank last. That's a great question, but you have to actually go in and dig a little deeper because what size co2 tank are you talking about now there's, many sizes of co2 tanks as you can see here, I'm surrounded by them. So what we're going to do on this video is we're going to cover the different sizes of tanks we're going to cover how long those tanks last and how much co2 those tanks will put out liquid and estimated gas. However, what we're going to be doing is letting you know what these.
Numbers are, but this is when the tank is completely open when you take the valve, and you turn it all the way open there's, many factors that go into these tanks, the different sizes are one factor. The other factor is the actual tank itself. The valve on the tank. How big is that orifice or opening in the valve, not the opening that you see that may be on the tank, but actually inside the valve where you can't see that's called the orifice.
Those are factors that limit the flow of gas that limit the flow. Of liquid coming out of these tanks and therefore subsequently that opening in itself. And of course, the valve how open the valve is are also going to dictate how long the co2 tank lasts. These are things that you need to know because I wish I could just give you a straight answer. But with all these other factors that go into if it's, very difficult to give one solid answer.
And of course, all tanks are built just a little differently. So this video, like I said, we're going to cover the basics, but. I'm also going to give you some more information that makes a great discussion topic, not only for us.
But for you, but more importantly, gives you the knowledge that you need to know to make an informed decision about what tanks you may need for whatever you're going to be using them for you might be using them for your aquarium. You might be using them for pool. You might be using them for special effects. Furthermore, you might be using them for horticulture there's. So many things that co2 is used for these are. Things that we're not going to talk about in this video, that's, an entirely different video as I like to say because it is, but we're going to be talking about the tanks themselves.
And of course, how long they last so co2 tank setups. I got our tanks set up right here, I'm going to cover these tanks first and foremost, a tank similar to this would be a 10-pound tank. Just to give you a preface of the set a tank down here.
This is an aluminum 50-pound cylinder that you could barely see. This is a steel.50-Pound cylinder this one is actually on a crate. This is a siphon tube, 35 pounds co2 cylinder. This back here, that's a nos tank, that's, not a co2 tank. But I thought it looked cool in the set, so why not leave it?
Maybe it can go in your car. Let me know in the comments. This one, this is a hundred pound co2 tank. These are large this one over here to my left. Your right that is actually a 135 pound co2 cylinder. These are all high pressure tanks. This one is a low pressure tank.
This is a 180 liter Dewar. Tank or what's called a bulk tank, it's, actually, a bulk tank, a bulk, co2 tank, the pressure on that is a little different I'm going to start with this one, and then I'm going to talk about these because I'm going to pop a chart on the screen and actually go over some different sizes. Some numbers some basic measurements and some weights. You want to know what the weight of a co2 tank is that's. All right here. The chart I'm putting up because it'll make it so much easier for you to visually see what.
I'm talking about because maybe you're sick of seeing my face right? So this tank this won't be on our chart. But this is a 180 liter doer.
This is equivalent to about eight or nine 50 pound tanks. This one resides at about 300 350 psi. Normally this tank will last 10 to 15 minutes depending on the output.
Now that is a liquid output for this specific tank if you're doing gas. It will last a lot longer you're probably going to get anywhere from 30 minutes to multiple hours again. This deters us. Determined by the valve, how open the valve is, and of course, the orifice and the output that the fitting has on the cylinder itself. So the numbers here and why we're going to be giving you the numbers on liquid?
Because the way a tank works is this if using this tank, for instance, if this tank was full of co2, you have about two-thirds of it actually liquid the rest of it is gas. The hotter it gets, the less liquid. The more gas, the higher, the pressure, the colder. It gets the more liquid, the less gas.
And the lower the pressure. So this tank right here actually has a glass interior, and it's vacuum jacketed between the glass interior that holds the liquid or whatever other material holds the liquid and the outer shell. And that vacuum jacketed or negative pressure is actually acting as an insulation. Therefore, these internally sit at a much colder temperature to build the pressure on them. You have something that comes out the bottom inside and wraps around the inside outer edge of this tank with a. Valve that comes out and back in that builds the pressure itself. These tanks don't have that whatever the outside temperature is going to affect these tanks that's.
Why I have to say this, because you need to understand how these tanks operate and how they function to be able to understand the concept of how much co2 you're going to be getting out of them. So the more you understand, the better off that you'll be in preparing and planning what you need to plan and prepare for with the co2 tanks. This particular tank is different. So that's, why we're getting this out of the way?
First? Okay, yes. Pressure. Does matter. Yes, the heat outside matters. But at the same time, we're going to be discussing these tanks because these are most prevalent and probably while you're watching this video so let's jump into that. Now.
So with this said, when you have your liquid that sits at the bottom of the tank that liquid converts to a gas, if you're getting a liquid output, your pressure is going to be the same. But your usage time is going to be different from if you had gas reason being again, using this tank, as an example for liquid, draw, you have a siphon tube that goes down to the bottom of the tank like a straw in a soda cup. The pressure is going to push that liquid out first then when all the liquids gone, what you have left is the gas that also is inside the tank. So you're going to have gas come out after the liquid, doesn't mean, the tank's empty, but for special effects purposes. Yes. The tank is empty. Because there's, no more liquid, however, if you're using regular co2 tanks, non-siphon tanks, what happens is that liquid that sits at the bottom of the tank converts to a gas as the pressure is let off as you use the gas more liquid converts to more gas that ends up converting over inside the tank.
You don't, see it. So what happens is you actually get the full use of the tank when you're using it for gas because you're using gas, whereas compared to special effects when the liquid is gone. Yes, the tank. Is empty, but technically the tank is not empty.
So you probably search for a couple of things online to find this video, such as co2 tank, setup, co2 tank, sizes, welding, co2 tanks, sideways, uh, no, co2 tanks or sideways here. However, you can't put them sideways, see so that's, not what we're covering here we're covering co2 cylinder, size chart and co2 tank sizes. So without further ado let's, pop this chart online on this video so that you can see what I'm talking about, and we're going to cover everything in. That co2 cylinder size chart. Now. So with looking on the left side of it, you have 2.5 pound, co2 tank, 14 inches high by 4.26 inches wide I'm, not going to cover all of these I'll. Let you do the rest I'm just doing this for the first this tank typically lasts about 0.05 seconds, that's with liquid co2 for gas again.
This is all relevant on how much you're using how open the valve is liquid. We know the valves all the way open because that's, typically how people use these tanks as will be the same with. All the tanks, but for gas, these tanks can last quite a bit longer. So for liquid consumption and liquid output with the valve all the way open 0.05 seconds.
Once all that liquid is gone. You only have a series of time left of that tank before it's completely depleted, and you're talking, maybe one minute or two minutes or three minutes again, depending on the valve. The aluminum tanks five pounds is what they weigh empty. Of course, the 2.5 pounds added to 5.
You get 7.5 pounds full that's, what the full. Aluminum tank weighs steel a little different. And let me preface this guys and say that these tanks on this chart, this is general information, it's, not extremely specific.
So aluminum tanks are made to spec. Some may weigh a little more than others steel, it's, it's like rolling the dice you got steel tanks. I've seen all different sizes. I mean, I don't have it here, but I have a couple of hundred pounds that are sitting right off set here, and they're all different sizes. The tar weights are.
Different which when you put the gas in it, they're all going to weigh different. So this chart is just meant to look over it and get a general idea. And of course, I have the chart at the link in the description below that you can see that because we want to make sure that you have what you need moving on to the 5 pound tank, 10 seconds, you have the weight of the aluminum the weight of the steel. Then you double it. Your 10 pound tank is going to last about 20 seconds that's with liquid output valve all. The way open your 15 pound tank lasts for about 30 seconds. Your 20 pound tank is going to last for about 40 seconds.
20 pounds is very common with special effects. Co2 special effects and uh, co2, uh, stage effects. These 20 pound 35 pound 50, 75, 100 is what they normally use on stage effects. So you stage effects, guys, pay attention. You got your 35 pound that's about a minute.
Now, if you notice here at least up to this point, 2.5 5, 10, 15 and 20. You take the weight of the tank or the size of the tank, a 20. Pound tank, 20 pounds, 20 times 2, 40 40 seconds. Now you do the same thing with 10 10 times, 220 a 10 pound tank times two 20 seconds. So typically you're getting about two seconds for every pound of co2 where this is different is after where we're at right now, you're 35 pound, you're, 50, you're, 75 and 100, because generally for some reason, the more co2 that's in the tank, the're going to get a little more the smaller tanks.
It stays pretty uh, pretty much the same again, don't quote, me every. Situation is different if you're in Vegas it's, a lot hotter okay, a tank that's sitting in 70 degree weather compared to a tank that's sitting in 35 degree weather, 35 degree weather you're going to get a lot more co2 out of it at least with the liquid draw. Then you are out of a tank that's going to be sitting in 70 or 80 or 90 degree weather, it's all relevant because of the pressure earlier in the video. Remember what I said, I think you do so jumping right back into this 35 pound about a minute 50. Pounds 1.25 minutes, 75 pound 2 minutes, 15 seconds.
And of course, 100 pound two minutes, 45 seconds. What I could do is technically say, a hundred pound, plus 35 pounds to equal this, 35 135 pounds, just to be safe. I can go 100 pounds, plus 35 pounds that's about 3 minutes and 45 seconds, even though it's not on the chart. I know that I have at least that and that's what I would know for this tank. Okay, these are high pressure tanks. You can't, take that same type of calculation and go for one of these doers or a. Larger tank now where this gets creative is if I take two 50 pound tanks, and I put them together generally, yes, I have about two minutes and 50 seconds generally you don't want to quote that.
And the reason being is this again, how much co2 is flowing in to the hose is the hose constricting. It is the fitting on the uh, the valve and the tank constricting. It is one of your other fittings constricting.
Furthermore, it is the pressure where's, the pressure at where's, the temperature at I'm saying, this like. This for a reason, the reason being is so many things affect this. You don't want to solely rely on this chart. You don't solely want to rely on these numbers. Furthermore, you want to use this as a starting point it's better to have more than not enough. So with that said, chart in the description below I've talked enough on this video, I think you've gotten enough information out of this. If you want to be safe at least look at these numbers for your co2 tank, because this is the liquid output you have to have.
Liquid first before you have gas. So if you base your numbers off of this, and you're using gas, you're going to have a lot more than this. Okay, I wouldn't say double, I wouldn't even say, one and a half more you're going to get more gas because this is all liquid output like I said, I'm, just reframing this. But as long as you plan according to this, and you have a gas output requirement you're going to be in the safe zone, and you're going to be able to calculate how much co2 you need without further ado. Without anything else said, because I've talked too much already I'm kidding, but slightly not do me a favor if you like this video, and you like the content here hit that subscribe button below likes notification bells. It does the algorithm good justice and promotes this video for those people who are probably searching long and hard and don't know where to find this information.
This information is given for you because you like to watch it. And these are questions that we see online all the time. I'm, Chris, this is croft. And this is how long can a co2 tank last I'm, saying, deuce, I'm, not out of here yet, how long can a co2 tank?
Last I provided co2 tank sizes. I've given you a co2 cylinder size chart, if you're welding co2 tank sizes for welding. And of course, your co2 tank setup, not on this video. And we did show you co2 tank sideways.
You can put these sideways. Okay, I'll. Talk about it. You can't put these sideways.
You just got to make sure that if you're using gas, they have to be a little. Propped up, and if you're using liquid, they have to be a little propped up as well. If you want liquid, or you want gas reason being is that liquid needs to fall to the bottom of the tank.
Just do it very carefully. We are not liable for that I'm. Chris. This is cry effects. And until next video peace, you.
