CO2 Cylinder Expert required (Real Gassing!)

[GuyGhibli]

Hi

We are using CO2 cylinders to fill some (very) large inflatables.

The standard fitment nozzle restricts the CO2 passing from cylinder to balloon (we empty the cylinder) and I want to inflate the balloon quicker.

I am guessing the opening is 5mm?

Can anyone advise - are there standard fitment cylinder connections that use a wider opening, in order that we can empty the cylinder in less time?

Hope this makes sense....!

Yes, for elephants.

Trawling Beer, Pub and Homebrew advice has not helped - they want very slow rate, likewise Wleding etc.

Is there an industry that would want to empty a cylinder in as short a time as possible?
Fire extinguisher? (Although they regulate the emptying too in most cases, I think?)

Is there a use where you want to fill a room with CO2 rapidly?

Or how do they fill plane escape chutes?


Mods feel free to move this, but General Gassing did seem the closest....

Why are you filling balloons with CO2? Seems a bit odd.

Compressed air would be cheaper wouldn't it?

Hi

Oddly, the choice of gas is not too critical - compressed air would be fine, it is just the rapid emptying of the cylinder that seems to be an issue?

Hi

Thanks for your replies!

Our CO2 supplier has confirmed that it is possible to get a "double nozel" on the top of each cannister - currently, we screw a pipe onto the single nozel.

I suspect that the narrowest point within the whole set-up is the (5mm?) hole at the nozel, and that within the restrictor it is much wider.

So if we have two nozels from a single cylinder, we can expect twice the gas to escape into the device in any given time, is that correct?

We have a spring-loaded mechanism with a pull-wire that causes the cylinder to empty.

Cheers!
