vortex cooler
The cold air gun is also called the local cooler cooling gun, vortex tube, cold, cold, dry air gun cooler, eddy current air gun, and so on,
It is a compressed air into the vortex generator cooling gun, vortex, and gives off heat and cold air.

There was some temperature difference between the two ends, but not enough to make it worth the trouble

I think this thing may cool the air slightly. Maybe. It’s really hard to tell if the air is any cooler than just blowing straight air from the compressor line. I’m definitely not blown away by this, and honestly I doubt I’ll use it since it only seems to make a marginal difference at best, and even then I feel like I may just be imagining a difference. It’s that small of a difference, so it’s really hard to give this thing a good review.

Another tool that barely works - more just a caricature of the real thing. Maybe could be better with some tweaking, but i'll go back to misting.

This cold air gun works, but not as well as my other one. To be fair, the other one is much larger (see pic), and more expensive. It is also much more efficient. What I mean by efficiency is that my larger unit seems to blow most of the air out the cold end with a lesser volume leaving the hot end. This gun is exactly the opposite, it seems to blow most of the air out the hot end.At a regulated 80psi, in a ~100*F shop, this gun produced air that was only marginally cooler feeling than just blowing compressed air directly. The situation improved slightly by switching from the double nozzle to the single nozzle. But what made the most difference was connecting it to full, unregulated air (~135 psi). At that point this gun produced noticeably cooler air, but your compressor had better be continuous-duty rated to sustain that volume. The larger gun produced much cooler air in all circumstances.I suspect that in a cooler shop it would work quite a bit better as even my larger gun, which can actually freeze up in a moist climate, wasn't super-cold. I'm not confident that with my shop temperature at present this will have much effect on tool life.Worth mentioning, the inlet connector is made for either 5/16" or 8mm hose. I suspect 8mm as 5/16" is an odd size. I was going to replace it right away (I use 1/4" hose in this sort of application, and have some good connectors for same) but the threads between the connector and the body are something I can't identify with any certainty. They're not NPT, nor are they a standard imperial or metric thread. They may be BSPP, but I don't have an easy way to check. No specifications are listed in the description, and no documentation accompanies the device. I ended up wrapping electrical tape around a 1/4" hose and using the provided fitting. That worked surprisingly well.I'll check this again in a month or two when my shop is cooler, but at this point I see little use for it.
