- DIY Evap Air Cooler. This design uses Two 5-Gallon Buckets (stacked high) to make an air cooling "tower". produces powerful breeze and low temps. (drops 80F air to 58-59F). The dual-bucket design allows the unit to hold 5 gallons (for all-day cooling). temp. tests and full build included in the video. *note that it can be AC or DC powered. for DC power - one 12v solar panel (15-20 watt) can power fan (10w) and DC water pump (5-10w)... or just use 12v battery. *be ready for summer... once it's built, all you need is water & sun and you've got cool air! if you like the vid. please rate, subscribe, and share.

EXCELLENT!! I have to give you credit (you deserve it)! You are good most often with what you do and the ideas you have. I've made use of a few of your ideas on several occasions, I live on just a small Social Security check as my only income, Ideas like this help make my life much more comfortable, bearable and livable. While saving me money! THANK YOU VERY MUCH! I sincerely appreciate your time and efforts, Respectfully John
Like I said before, your designs not only make life more comfortable, they can also save lives. All on a budget! Thanks again for sharing 🙏
hi there and thanks. i try to keep everything simple, practical, inexpensive and useful (and easy to make) so that the projects help (and inspire) as many people as possible all around the world. a few other things i focus on are off-grid designs, using recycled or repurposed materials and harnessing alternative energies (mainly solar).
Thanks for sharing - best DIY bucket evap cooler on youtube. Built one based on your design - guaranteed 20 degree drop in temp every time.
I LIKE THE UPDATE- WITH THE ADDED LOWER BUCKET AND YOUR FINE DETAILS HAS CONVINCED ME TO MAKE ONE FOR MY 20 X 8" TRAILER HOT BOX! IT WAS 96 DEGREES YESTERDAY AND THAT HOT SHEET WILL MELT EVERYTHING IN ITS VIEW!!! THANKS, EAGLE-SAN IN COLORADO
New friend here of your channel today from Martin Midlife misadventures channel. This is a fabulous video sharing life enhancing comfort creating atmosphere. Thank you for your time and video. HUGS and GOD bless us everyone ❤
Thanks for sharing this. I built one because of all the smoke from the fires in Ca. preventing the use of the large house swamp cooler. We move it from room to room as needed. Takes the edge off of the 100 degree weather.
sweet! ✔😎
Brilliant!! I was looking for a simple way to cool rabbit hutches during the summer! Continue the stove piping up and thru the hutch up close to the ceiling. Cut gashes out of the straight piping allowing the cool air to escape into each cage of the hutch! This allows rabbits to lay at back of cage under the pipe to cool off!! Ur awesome!! Thank u so much!!
really excited to try this! Im gonna make one for my mom to help with heat and cooling costs. Thank you so much for doing this. And explaining in a simple way.
very welcome and have fun building! 🙂
simplicity is power! very cool!
Indeed!
Outstanding!! Kudos to you!
You are a genius. Thanks for the tutorial!
You're welcome!
Cool build.
Amazing
Dude!!! You are an Air-conditioning genius!!! Very innovative!😀👍
Wow, thanks!
@@desertsun02 Heck yeah!!
Excellent!
thank you! 😎
I expect the power grid to go out in Phoenix, this year, the way things are going. I plan on making this ASAP
Same. Going today and was looking at video again for materials. Make sure you have solar portable setup. Here in Tempe.
Yes it this one I'm going to try thanks man for the info
sweet!. this one works great
genius! Never seen this. thanks for sharing.

The Hitech Hobo 😁
Kristofer Travels This would work great in your camper.
Awesome
I'm going to this definitely in the sumer
Nice!!!!
Great Video! None of the others took time to go over how much of the cooler pad and screen a guy would need.
hi there. thanks! glad it helped you ✔
good desighn
Great design and video like the others! Was wondering what the recommended sq ft this would be good for though. Would like to make one to compliment my window unit AC and perhaps make it solar like your setup.
As you said in the description, the two bucket design allows for all day cooling. Additionally, it raises the air so you can point it right at yourself while you sit and (hehe) chill.
This is cool! No pun intended. Also look at a 12-volt air conditioner designed and built by wallabydam.
COOL! Pun intended ;-)
I think actually having two in two different parts of the house might be more effective though don't you think? This would work better than one in the same spot but spreading these out seems more effective
"that time of the year"
Really creative piece of engineering! I wish I could get one these to work here in Los Angeles. I did my best with you evaporative cooling ice chest set up and even filled with ice couldn't get any coolness. It may be to dry here.
h there and thanks. since you're in LA, you should be able to get these to work. the drier the air the better they work (typically). try one of these "no ice needed" designs. (i have 2 more units/vids coming out in the next few weeks... one is a 20" box fan conversion and the other is a small window unit... and they all work great)... btw - the ice-based ones are more of a conduction-cooling device (they don't take advantage of the properties of evaporation cooling)
Nice project. Simple and effective! I believe you can get a DC fountain pump and solar cell to power it on Amazon.
hi there. yep amazon should have those 🙂
Can you share the pump data (GPH) that works ?
I think your stuff is really cool and I've been watching for a while, so I'm wondering why you make these? Is it just a mental exercise or a fun hobby?
Suggestion for high humidity areas or if you’re needing maximum cooling.... since this system efficiency is limited by how easily water is able to evaporate. If you use a mixture of water and alcohol it should dramatically increase the cooling efficiency. Not sure about odor but it should majorly increase evaporation rates and cooling.
Do you have a recommendation as to what water/alcohol ratio would be most effective?
And what type of alcohol?
@@therationallion - I think any alcohol would work. Rubbing alcohol would certainly be the cheapest. You might try starting with a 50% solution of rubbing alcohol and water. The higher the percentage of isopropyl alcohol the more water you should be able to get away with using. Ultimately gonna be trial & error but the theory is at least sound.
@@motorgearhead Thanks for the reply, I'll definitely be experimenting.
@@therationallion - let me know how it works out please.
Yes it'll be cool but then you'll be breathing in alcohol vapors! Better approach is indirect evaporative cooling. Unfortunately for humid areas you'll never get temperatures below the wet bulb temperature. Instead, maybe some combination of dessicant and indirect evaporative cooling would work if you can afford such a complicated system instead of a compressor based AC.
If u intergrate a coiled copper tubing, it would bebthe icing on the cake.
What an awesome idea!! Gonna try to miniaturize using PC cooling fans (6vdc) and a small solar charger for outdoors buffs !! Thanks
How do you connect the fan and the pump to a single 12v battery? Can you just splice the wires together?
What pump do you use?
PS: Please post a detailed list of all the parts with their proper names (With AC and DC options; I might get a couple made for my old lady friends on solar) that you used here so I can take it to Home Depot when I go shopping. It's 80 miles away,, so I can't forget anything or get the wrong parts! (Including the type of fan you are using and the little white pvc plug thing at the end of the tubing.) And, did you use all 10' of the tubing for this one, or less?
You are going to be the guy that creates the water powered automobile
The government already killed that guy
Tip... spray bottle of water/alcohol will drop inside car temps dramatically in just about 2 min when sprayed inside the car.
Mr. Desert Sun, You have made about half a dozen of these contraptions over the years, all great. What I want to know is which one actually works the best (Ice/Cooling agent lasting longest; Degrees of Temp Dropping) in your opinion? I am not a handyman type; little to no tools skills and will be asking a friend to put one or two together for me. So, I want to get it right, the first time! I don't use solar panels, I am on the grid, so electric demand is not a top concern. I live in an RV @ 31.884 Longitude in NM that climbs to 115-120 Degrees inside for most of June, July, August and the 5,000 BTU AC unit only lowers the temp about 10 Degrees, so it is fairly unbearable. Thanks for any info. klee.
hi there. i normally don't rank them (because they all have their advantages...) but... if you've got the right climate and you want to cool the largest of areas (*more than a room) i'd have to say my evap. air cooler designs that use 20" box fans. i have 3 of those (at least)... but my newest one is really posting some impressive numbers. it's cooling my ENTIRE HOUSE all day in 100F heat. it's cheap to make and unbelievably simple to put together. posted 2 weeks ago (5/1/2018) if interested here's the link th-cam.com/video/xDze9f6Jx8Q/w-d-xo.html
Gee Thx! I Hadn't seen this newest one, and just by the increased Fan size, I bet it will do the job for my living in the Desert environment also. You're the best, thanx again, I appreciate your creations and helping others. klee-pjp88029
desertsun02 same question but for a 25 foot rv. What's your suggestion on the best one? Great channel!
It would be nice if you could provide Amazon links to all of the materials for the build. I will build one of these to run off of a solar panel. I will have to do the research myself to find the correct size of pump, fan, solar panel, battery, voltage controller etc. Thank you for this great idea.
hi. providing amazon links is proving too difficult with some of the products. they switch the links so often i can't keep up. and if i forget then there are just a bunch of non-working links out there. best to just search amazon for best price.
I like your video's and admire your percevearance. I have a question cons. The "dual bucket evaporator" : what is the ingoing water temperature and the actual delta t over the device? Thanks
hi there and thanks. i didn't measure the starting temperature of the water (but my tap water is usually 77-80F). with a drop to about 60F. so about a 20F drop. humidity at time of test was 5-10%
thanks for the clear thorough video! ill keep tweaking but have not been able to get a temp drop in my 90º, very low humidity room. my understanding is swamp coolers function best with a vent to remove hot air and humidity build-up from the room, do you have a vent in the room where you use this? could you say why or why not? again thank you!
hi. yes you have to vent it. if not vented it will increase humidity and the cooling will be very limited.
yes
how big are the intake holes and drain hole? trying to figure out which hole saws i need
Amazing tutorial! I am thinking of using this when I camp. How long will a bucket like this last per filling of water? Have you thought about doing 2 layers of cool pad to make it thicker?
hi. and thank you. this should work great for camping. how long the water lasts will mainly depend on how dry the air is. (the drier the is air, the more evaporation that will take place). i usually get several hours before i need to add more water. i haven't really thought about using more padding to make it thicker. i don't think it would make the air any colder. just the one layer of pad seems to drop the air to 'the limits' allowed by evap. cooling. if you use a much faster fan then a double pad might be an advantage.
Could you just add a third bucket, at height, and do away with the pump?
So I have 420cfm fan and the evaporator pad but it never drops temp down. I built a pvc cage with small holes at the top. The evaporator pad is underneath the pvc with holes. The pump is circulating the water. The temp doesn’t drop at all. Water or air
hi. sounds like a much different build than the unit in the video. i'd have to see the build to figure out why it's not working.
Thank you desertsun02 for the great video. You inspired me and the weather is killing me so I ordered all the materials and made one. It was a lot of fun and blew cold air until it didn't work properly. lol
I am having a few problems. I have put tons of holes in my tubing but they seem to just close up so my evaporative pad just dries out and fan no longer blows cold air. How do you keep the hold open?
The second problem I was having a found a way to fix it - my tubing was not staying up and it was getting crimped so I put a wire down the center of it. Now it holds its shape better and it does not fold on itself.
I am pretty sure I bought the same type of tubing you are using - but it is not working very well.
What do you think the problem is with the holes not staying holes? Water is NOT dripping out of the holes. When I first make a hole the water shoots out and then it stops.
hi there. first, i'm glad you built it and that it's working for you! to keep the holes from closing try drilling the holes out with a very small drill bit. use a one-sixteenth inch one. that should work good. that will remove enough of the tubing so that is doesn't try to reclose. possibly just using a fatter nail or push pin could work too.
@@desertsun02 thank you so much for responding! I tried a bigger tool and that didn’t work so I’m gonna try drilling like you suggested! 🤞 fingers crossed!
Wondering if I could run this off a solar panel in an RV
Yes you can, I will be doing it with my solar generator
can it cool a small/average bedroom? if so, can you share your experience as example? or tell us how many degrees can it cool an 11x11ft space in 30min?
im gonna try it soon and i will let you know i think it would work. have you tried it yet? Just realised this was posted a year ago lol
Great design, just curious, why did you choose "DIY soaker hose" versus pre-made 1/4" irrigation soaker hose?
hi and thanks. if i remember right, i just didn't think about those soaker hoses at the time. it might work very well though. i'd say it's worth trying 👍🙂
Awesome video! Couldn't you also put salt in the water to make it colder?
hi. it might work (but i haven't tried it)
Hey do you think having a thicker pad would increase the cooling or put too much strain on the fan?
hi there. you could probably double it up if you want to. the pad is designed to work with fans up to 2250cfm (roughly), so even a single pad works great.
How much do u charge to make these?
Planning to make this for my mushroom growing. I'm hoping it will add humidity to the air. Do you know how it effects humidity?
if you use it in small confined spaces with no ventilation humidity will certainly go up. 🙂
Okay so I am super ignorant but I am trying to build something similar to this for burning man. What is the metallic tube called that is coming of the top of the cooler?
hi. it's called a 8 inch 90 degree round adjustable elbow
Trying to build this but no experience. So I got the pump today, 12V DC. There's no place on my charge controller or on my solar generator to plug in this kind of cord. The instructions are in Chinese with no pictures. Got any suggestions or could you make any if you had pictures? Really frustrating.
Instead of using a water pump, do you think it's possible to make it with a overhead gravity driven water drip?. Maybe if the hose and drip holes were big enough in diameter?
hi. i'd have to give that one some thought
Can you please tell us the fan you're using? Can't seem to find it online without knowing what exactly to search. Thanks, man!
hi there. it's a 12VDC (10 watt) "auto" fan. i get them from walmart (sold in the auto dept). amazon sells them too
hey can i get a materials list for this build? specifically the fan and motor? thanks!
fan?
So I made the two 5gal version, but I'm just not getting anywhere near the low temps you show. Not sure what I'm doing wrong. It's 80 degrees in my house, pump is working, pad is getting wet, got plenty of holes in the bucket...but something just isn't working right. The lower bucket reads 64 degrees with ice in it, but the air blowing out doesn't get below 72 degrees. Somehow the air exchange isn't happening. We put about 4gal of water in...is there a chance that's too much? Any tips, thoughts?
hi there. could it be the humidity level in the air? i just checked an Evap Cooling Chart (you can google that) and it shows 80F air temp at 55% humidity would give you 72F air. i've found those charts are very accurate. *average's 5-8% humidity in my desert area... sometimes lower! - i saw a 39 degree temp drop once... but they usually average 20-30F drop
desertsun02 I appreciate the insight. We're pretty dry this time of year as well, but you may be on to something. I'm going to try a little tinkering and see if I can get to drop a bit more. We're cookin! 😁
awesome. one other thing... make sure the pad is saturated (if it's too dry the temps will go up fast) but this one really works great so keep at it :)
desertsun02, thank you for the help. It's much appreciated and I enjoy the concepts I'm learning from your videos. Keep it up.
Don't know where you live, but they won't work in the Midwest with hot, muggy conditions. These devices work well in hot dry climates.
How much of an improvement is the 2 bucket version compared to your 1 bucket version? Does it have a larger temp drop?
hi. with the bigger reservoir and the extra air holes this one is more powerful - covers a larger area. temps on both drop down about the same.
What size pump... Gallons per hour. Don't want to get to powerful, or it won't drop but spray out the hose. Thanks
hi there. i used a 200 GPH one. a 150'er would probably work good too
How long does the 5 gallon and 10 gallon last? I live in AZ and it can get up to 115-120 degrees during summer. I will not be able to work from home much longer and would like to use this in my newly adopted pet's dog house that is 4ftx4ftx4ft.
hi there. it depends on how dry it is. (how fast the water evaporates). you should be able to get 5 or 6 hours before you need to refill the dual bucket unit with water. if you just make the single bucket setup then it's more like 2.5 or 3.5 hours. (but this varies)
You live in Florida??? I thought it doesn't work well in very humid areas.
hi there. nope not in FL. i'm located in the desert(southwest).
Hi, thanks for the great video. I’m trying to build one of these (as they say the devil in in the details) and have a few questions.
1. how much better is the double bucket design than the single bucket design? I like the fact that the bottom bucket holds a full 5 gallons of water. What are disadvantages of the double bucket design?
2. What is the exact model of fan and pump you are using? Do you have amazon links for these? Also what is power consumption when both are running?
3. Is there anything special about the window screen you’re using? I couldn’t find that exact one anywhere, but not sure if specific qualities are better (ie ultra fine, standard, etc)
Im having a really difficult time finding evaporative cooler pads in my area (but this unit will be used in an area where evaporative cooling works well), I can only find 29”x30”, I can’t find 28x34, will the smaller size work ok?
1. The advantage of the double bucket design is that you can drill the top bucket full of holes, for more air flow. Also, the evaporative pad won’t be half submerged in water. The only disadvantage that I can think of is that you need two buckets - a larger unit.
2. According to the first video, it looks like a 6-inch 12-volt automotive (DC electric) fan unit is being used. I am using a 6-inch desk fan (AC electric) that I have removed the base of.
3. Don’t think the type of window screen will change the outcome. I am using some general window screen I found at Home Depot.
4. As long as you can trim it down to 13 inch height by 30 inch width, you will be fine. 30 inches seems to be the inner circumference of the 5-gallon bucket.
I live in Valdosta, GA. I have no central air right now in the medium sized bedroom that i am renting. Room temp is 94 degrees. Do you think this will work for me and if not, have you made anything that may work for me?
hi. the humidity where you live might be to high for this but check out my latest 4 air cooler videos. they all show how you can make an air cooler with no added humidity. here's a link to one th-cam.com/video/5YVPu9hfhZo/w-d-xo.html
Where did you get the dura cool pad? From the looks of everything else, I’m guessing the rest of the supplies came from Home Depot. I wasn’t able to find that pad on their web site.
hi there. i don't see the pad on their site either (but they have boxes and boxes of them in the store). if you type the search term 'duracool evap pad' into search engine it brings up a lot of them. if interested, amazon has the pad for about $8 www.amazon.com/dp/B000UJDVIY/ref=asc_df_B000UJDVIY5444179/?tag=hyprod-20&creative=394997&creativeASIN=B000UJDVIY&linkCode=df0&hvadid=167155689281&hvpos=1o3&hvnetw=g&hvrand=7193191279482081285&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9030009&hvtargid=pla-304692300946
desertsun02 thank you for the response and the link.
I just saw rolls at Wal-Mart and also cut rectangle (replacements) as well. I bought mine at Lowes.
would it be possible to do this in a 20 gallon trash can with a radiator fan?
hi. yes, that sounds very possible. 🙂
This is great... I plan on making the larger version, But I'm a stickler, and that's no stylus, that's a compass 🤪
Will this work if I just need more humidity?
hi. yes. if you put this in a room with all the doors and windows closed this will act like a humidifier
What is the blue pad called? Where do you get it?
hi. it's called evap. cooler pad. you can get it at the home stores (home depot and lowes both sell it)
I made your design but with a laundry basket and 5 gallon bucket.
sweet!
What kind of filter is that?
hi there. it's a 'Dura-Cool' evaporative cooler pad.
How long does a single 5 gallon fill of water last?
hi. about 5 to 10 hours
how much does this drop the indoor temp in the desert when its 90º-100º indoors?
hi. it will depend on the humidity, but it an drop it 20 or 30F if it's dry where you live. for an estimated temp drop you can check an evap cooling chart. those give an estimated temp drop based on unput temp and humidity. they are accurate to within a degree or two. 100F will drop down to 71F if humidity is low. 90F air can drop to 69-70F with humidity from 15 to 20%. are a couple of examples.
@@desertsun02 thanks! do you have any recommendations for when monsoon season arrives?
Where can I find a link to purchase the fan you use? Thanks.
hi. i just did a quick search and i don't see exact link but it's a fan sold at walmart (in their auto dept). sold under the name "auto expressions"
What kinda pump do I need?
hi there. any small water pump that is rated from 190 to 220 gpm works good. (a little stronger would be okay too)
Where can I find cooling pads?
hi. most home stores like home depot have them. amazon sells them too.
desertsun02 Thanks man
What's the GPH on the pump?
hi. it's 200 gph

desertsun02 thanks brother I appreciate it I’ll be making some of these today
what cfm for the fan do you recommend ?
i'd say 150-400 cfm (for this design). maybe a little higher too.
Can you sell me a book that you make about all the materials and tools and steps about how to make this? An ebook or something?
hi there. i don't have an ebook or anything. the vids (and description section) are the "how to" or instructions on how to make it. if you have any specific questions just drop in comments area (as a new comment) and i'll get back to you. btw - it's always a good idea to drop in question as a new comment because i don't always see the replies.

@@desertsun02 Thank you for your prompt reply. If I may, I have a few other questions.
Where did you buy it? I can't find anything under 30?
Is it a fountain pump?
@Teekoness i got that one at harbor freight tools. last time i checked it was 15 or 20 dollars (but it had the extra feature of shutting off when the water got too low). good feature but i guess they had to increase the price. amazon is a good place to get them too. they have them for 10-25 dollars
@@desertsun02 Thanks again.
Sigh. May not be able to afford that now. Maybe I can stick ice in a container above the pad and it can wet it as it melts?
