It doesn't work well at all. Lewis guns run a little cooler with the shroud removed. If you think about heat transmission and thermodynamics, the reason will be obvious.
I can't believe no one has suggested using freon yet. lol
Canned air is Freon ,like the label on the can says. LOL
Even in Joisey.LOL
OK ,If you don't care for the Lewis idea.
Lets go Vickers ,seal the ends of the tube with "O" rings ,fill
with water, provide a small vent.
When steam starts to escape, it's time to take a break. LOL
Water is better and the BTU's it takes to make it boil is even better
except at high altitudes.

A couple of guys at yesterday's F-class match had little battery operated bait aeration pumps with an empty cartridge on the end of the plastic tube. They'd shove the tube into the chamber between strings. The rotation of the squadding had me shooting two strings back-to-back. When I asked for a little time to let my barrel cool one of the guys brought over his little pump and let me use it. The air flow was completely negligible. IMHO it was just a placebo and pretty much a waste of batteries. But it was nice of them anyway.
N.B. The idea might work better with a different air mover, such as a small computer fan, designed for high volume at low pressure, not to push a small volume of air through and aerator block under water.

You might want to give BarrelCool a try. www.barrelcool.com . Relative to the typical bait or aquarium pumps I have seen, this exhausts more air. It also doubles as a chamber flag so you can use it between strings and a RO won't harass you for not having an ECI in the gun. Many F-Class shooters and people doing load development have found it to be useful. See video below:

I have tried most of the things mention here. You are better off to just buy a barrel cool and forget the rest. They work that well.

How long do the batteries last?

They have 3 cr123 batteries in them and the paper work says they last 7-8 hours. I have used mine a fair amount since I received it but at 5-10 minutes at a time 7 hours is a long time.
Less than three hours, and they're pretty pricey.
I don't know yet. I've one of the first ones shipped, I use it every week, and I'm still on the original batteries.
A bottle pressurized to 3000 psi and high powered rifles..................... is that a safe combination? If I had such a bottle on the firing line, would it be better if you accidentally shoot ME rather than my high pressure bottle?

I've used alcohol (on a rag, wrapping the barrel), and it works very well. the issue is that it strips all of the oil off the barrel and unless you wipe it down with oil, it will rust. this is on stainless barrels BTW. (yes, stainless *will* rust under the right conditions)
compressed air / air can is too slow/too expensive.
I now use a tried and true PD'er fix: a wet rag that resides in the cooler (along with the gatorade and water). remove, wring it out, and wrap the barrel with it. usually the barrel is cooled down within 3-5 minutes. simple, easy, cheap.

I have 6 weeks on my original batteries that came with the unit. Say they last 8 weeks worth of use. I shoot them rifles roughly 6 months that 26 weeks so that would mean I need 4 sets of batteries for 26 weeks of use. I just checked, a box of 12 surefire batteries are $18.98. So for less than $20 I can keep my $400 barrels cool for the summer. To me that is pretty cheap air condition for my rifle barrels.
