Looks Great! I like! The dry air will help a lot. More importantly, you've taken the steps to avoid passing hot dusty air. (and depending on RH and temps, 7 could easily be the max obtainable when you measured) You've covered the key details, and you understand the 'why', in case you have to mod it...

Thanks guys!

So you've got to look at: ⋅ inadequate gap, ⋅ dry corners at the end, ⋅ possible leak past the lid to the interior negative pressure volume. OK, I did everything you suggested, basically rebuilt the interior... It appears to help slightly. Before I had a 5.6° drop; now...

Note: those pumps do work but sometimes (as I found) they don't have enough pressure if you have holes in your tubing that are too large. What will happen is that the holes close to the intake will release most of the water, and the other holes will not spray any. The 10-gauge wire FIGJAM uses is a...

That's why we use a return air register instead of holes for the unicooler. It keeps the water flowing to the inside while providing max air flow. It looks like you will have air flowing OVER your pvc which will Not let the cooler work at its best. Are you talking to me? The walls of the Genuine Jo...

Gotcha. Will report back.

That might work with the fan on low. But due to using a limited area of the pad, it won't cool as well as a bucket cooler. I'm not following this... what do you mean by a limited area of the pad? In principle, shouldn't this cool much more than a bucket cooler? Otherwise I'd just have built a bucke...

Thank you. I think the front lip seal is good, but will check. Good idea on the end caps. I was careful to extend the pad there to avoid a gap, but you're right, better if it's wet. The gap still looks sufficient to me at the top, but maybe is it not. I can keep the material from puckering out below...

You need to pay attention to the details... I've read this whole thread, but my cooler has issues, so fair enough... THE GAP IS AN ESSENTIAL COMPONENT The gap provides ample air flow distributed inside the container to all of the pad area to meet the demand of the negative air pressure on the other...

I've got one low res evaporative cooling chart. According to it, you're showing around 1/2 the drop you'd expect (~9F). At playa humidity & temps, you should get more of a drop, but it appears there are issues. Figjam has already pointed out the need to have the pads away from the sides/holes. ...

Bump... help? I head out for Reno on Wed. Need to get the cooler in playa shape tomorrow. Thanks for any insight. It's done!!! And... I *think* it works? The air feels cool/cold, but the thermometer says it's only dropping from 74.8°, 61% RH to 69.2°, 78.1% RH, even with the fan on high. Is that bec...

It's done!!! And... I *think* it works? The air feels cool/cold, but the thermometer says it's only dropping from 74.8°, 61% RH to 69.2°, 78.1% RH, even with the fan on high. Is that because the air is not dry enough? Or do I have a problem? http://www.hearn.to/cool.JPG It's hard to know if I have i...

Not sure why people are putting the Endless Breeze INSIDE the cooler, but ok.........I guess. :? I put mine outside the Genuine Joe. I hemmed and hawed, and would like it inside just to make a smaller form factor, but (1) then I'd have to move the switch, and (2) it seems like a harsher environment...

First, pictures of the finished build! Very cool! Mine is almost done. I went with the Genuine Joe trash can. It's perhaps closest to this design: https://medium.com/@immunoglobulin/seriously-simple-guide-to-building-a-swamp-cooler-266aaf7657a1 but in the tall trash can. Pics once it works. Will po...

Great, thanks!

Well. I guess I should have looked here before figuring out all this stuff myself, or not. Too late now, everything is ordered and on the way or already here. I'm building a bigger swamp cooler for my yurt -- my understanding is that the bucket coolers are not up to the task. So this is a figjam-sty...
