Ep 11 Dirt Cheap DIY Dessicant Air Dryer 

Love these videos... and the fact that a parent is so interactive with their child. You both give me hope for the future of society. Very Cool and thank you.

this message is for dad ,,,sir you have done a fantastic job i tip my hat to you

Very nice project Hannah. I love how you explain what you're doing as you go, as it is fun and easy to follow. Thanks for sharing and keep u the good work!

Just another grown man with an engineering degree learning about air dryers. Don't mind me.

Nice work, Hannah! My daughter Nika is super excited to see you working on your car. She's 8 years old and likes to work on projects too. She said "I'm a mini-version of her!" Looking forward to seeing more as you make progress and hope you are enjoying your summer! Sincerely, Tom (and Nika) Z

This and your video on slaving multiple air compressors are worth twice the price of admission! Keep on Keepin' On, Young Blood! Girl Power!

Amazing job! I own a 2001 Mexican beetle, which is one of the last beetles made. I love your videos, keep it up!

Hannah you have done a great job in making and explaining how to build an Air Dryer for your compressor. Great job :-)

Nice work, and excellent foresight including prices for each item. Now we can see how much we're getting screwed with plumbing supplies!

First off good luck on the bug rebuild. Your father/mother taught you well about doing things safely. I look forward to your next vid.

your shop skills are for real and everytime you dropped those fittings i started laughing .

Hannah your wonderful!! Thank's for teaching an old dog a new trick.

Amazing. This just put a whole lot of smile on my face. was just here to see how a desiccant dehumidifier looks like and was pleasantly surprised to see someone probably half my age able to make one by herself (when I have no idea even what it is). Love Love love.

Hannah I don't why you haven't posted more videos but if you can it would be gratefully appreciated. You give a lot of people a lot of help and for that I thank you. Never let the haters stop you just delete their comments and carry on. I still want to know what happened with your bug good or bad. We all learn something even from failure so carry on and love all 13 of your videos.

I like your design a lot! I'm going to make one of these myself. Awesome idea!!

That is really cool, keep up the great work and pursuing your passion!

Hannah, at some point in your life, we’d all love an update. Did you finish the bug? Did something happen that prevented finishing? Was RU-vid just a place you decided not to be as a young person? I still show your videos to my students at school as an encouragement, and it would be cool to have an end to the story (even if it didn’t go as planned, much of life doesn’t, and that’s a fantastic lesson for kids too).

Great video, great content, well presented. Loved it.

Kiddo, you're a better mechanic than many of the guys and gals I worked with building airplanes! Great job!

Many clever ideas implemented in this thing. Good job.

Nice sandals, i like your presentation i think you are a little star in the making!!

This has to be one of the most helpful videos I've ever seen on here!!! Wow amazing great job keep t up!!!

This build started going a different direction than what I was looking to do... but you ma'am, are hilarious.

I'm gonna build this and put some mesh around the tube in case it explodes (even though Thor disagrees). I love your channel, Hannah! I've learned a lot from you. Thanks!!

im going to build this for my sand blast cabinet. thanks for the upload!

Thanks for sharing this. I'll hopefully get to make one someday. You seem very comfortable in front of the camera. Best wishes, Jim

Nice job Hannah. You have things under control. Good day too.

Built mine following her directions. This thing is amazing. Work perfect.

Hannah, when can we expected to hear/learn more from you. Good job!👍

Somehow her videos popped up after searching how to weld. I have a daughter slightly older that hannah in these videos. Good job to mom and dad for raising a smart one 👏👍

You just saved me from buying that same dryer to use with my sandblaster. Thank you very much 👍

Love the channel. Keep up the good work. Subscribed

Omg. First video of you I've seen and you're awesome. Very articulate and informative

great videos. I teach a high school shop class and I will share this with my students.

aaaaaaaand,,,,, she can also do some machining!!! god bless whomever raised you young woman

As an EE student, I think this channel needs more multivariable calculus.

This young person has such a super cool way about her. If I have had a rough day at the office l come and watch her and feel better in no time. This girl is a winner. I am a very big fan. I just don't know what I am going to watch when she gets her bug done???

Keep it up kid, you'll go far with that attitude and brain! I enjoyed your video and learned something!

Very good job to the girl making it & the parent(s) to help her do it. Wish there was more families out there that could do things together like this & kids that want to learn with their hands and not electronics. Might have to make one for my air compressor & see how well it works.

great vid !!! good thing your reading from a card to keep everything organized

I wish i had a teenage kid this productive, creative, and brilliant!!! she is such a cool character

Great idea and awesome assembly video. :-)

Can't wait to show my six-year-old daughter your channel keep up the good work !!!

For those who are concerned about Explosions ... You could make a 3/4 inch plywood frame around the outside (top, sides, NO bottom) and a 3/4 inch plywood door on hinges to open when you want to work on it or change desiccant. If it were to blow it would blow all the chips out the bottom onto the floor not causing anyone any injury (or hardly any).

Nice job! I have a long zig zag of copper pipe with drain valves after the compressor that gets rid of most of the moisture but I still want the air drier for plasma cutting and HVLP spraying. Your idea is just what I needed to keep from spending more time emptying the desiccant container than working. The one significant change I made was to use sintered bronze air mufflers for the filter instead of drilling holes in the pipe and using a screen. They are inexpensive and work well. Thanks again!

I like working with pvc too! Here's a tip... When inserting your glued piece into its mating surface, start a 1/4 turn off center and insert it straight then give it the 1/4 turn to center. This twist helps seal the parts... Good video!

Very good job well thought out. good video

Finally got mine built. This girl is talented. Love when,she says FREEEEE!

Outstanding job

Very inspirational work, Hannah! Please give us an update on how well your Air Dryer works. With regard to PVC as a containment vessel, industrial users with which I have worked are concerned about the pulsations caused by on/off air releases causing micro-fractures in the plastic pipe which eventually cause ruptures and explosions. Just an FYI. Keep up the good work!

I would love to see a picture of your Bug! and Congrads on your Skills. Breath of fresh air.

your poppa and or mama must be soooo proud of you keep it up girl!

Great video! I'm making one of these for my shop, too!

What a breath of fresh air. Love this kid.

Impressive!! This video gives me hope for the future. Keen it up

Just finding this in 2023 and sad to see you haven’t posted in six years. By far one of the most entertaining how-to’s out there. Subbed anyway in hopes that you will come back!

Love your enthusiasm and way you presented. Very well done. Your charisma makes me want to learn more! P.s Chris only lives down the road from us :-P

Great Video, love your enthusiasm! You should put a list of all the items with lengths you used in the comments on the video. Great to see a young lady doing these type of videos (I know years ago) but I have a 4 yr old daughter that I hope one day will have the same interest and knowledge that she and daddy can create some interesting, educational, valuable videos like this! Thanks!

Just saw a couple of your videos for the first time. I made a desiccant drier for my compressor with galvanized steel pipe. It isn't as snazzy as yours but it does the job. I don't want to be That Guy but it really is fairly dangerous to make this out of PVC. Ignoring anything else, PVC is far more likely to break if, say, something falls on it. Combine that with the pressure behind it and it gets ugly. You never see PVC being used for air lines in industry for good reason(s). Anyway, you definitely have what we in the industry call "madd skillz" when it comes to building things, and I think it's awesome that you build stuff. You remind me of me, though you're way ahead of me on when you started welding. I used activated alumina for my desiccant. It's cheaper and, IIRC, a bit more effective, and it doesn't break apart when it gets really wet. It doesn't have the indicator but I personally prefer that, as the cobalt in the that is nasty stuff.

A result of great parenting... Great job dad and young lady...

You done a fantastic job

Amazes me how some men on here are scared a young lady can teach them something, Hannah you are awesome keep up the good work, happy to see you can share your knowledge with others, keep it up you have a fan here !

Clever ticking high pressure pipe bomb you made there buddy. 👍.

AWESOME video! We may construct this DIRT CHEAP device for our brewery to dry the air powering our keg cleaner! Cheers!

Great video little lady! Just do not know what else to say. You already have talents and skills that old guys (and gals) envy. You will do well and already on your way! JJ

Awesome job

That kid is a hoot, and well informed. Enjoyed the video.

Surprisingly informative great job kid

Cool! Fun project, and useful. :)

Cool project, very useful!

wouldn't care if it worked,the presentation was worth the watch.the fact that it does work was a bonus

Great job!

holy hell look at that awesome looking motor behind the grinder!

That's a nice design on the drier ! I didn't know the drier beads could be regenerated, that saves a lot of $$$ ! I'd just add metal piping before the drier, sloped back to the compressor, to help condense water out of the air. Build a tip tools drip loop too, they work great. Make more videos :)

you are doing a great job on your videos,, but I've been doing this stuff all my life and I really think your air dryer is dangerous you need to specify what pressure you are using because this will blow up eventually.please edit this video for safety reasons, but again your doing a great job and so far this is the only video that is just missing some very important info, keep up the great work you are an inspiration to other young people for sure.

Wish my grandson had half you ambition young lady. Who ever is your mentor is an outstanding individual. I would say that in your not to distant future you will have many doors of opportunity open for you. Good luck.

You are bad ass! I work for castair in Mn , air makes the world go round n round

Very good video! You definitely have a good future with these videos or as a maker.

Fantastic video, great knowledge base. In order to minimise the safety issues with using pvc piping i would recommend using 1 or 2 pressure relief valves rated at 8 bar (100psi) (1 at the entrance and one at the exit). This is within the operating pressure according to ASTM D1785 for all your pipe tube diameters. The problem with PVC and in fact anything brittle is micro fracturing initiated by pressure cycling. So try to keep the pressure constant in the desiccant dryer you built and insert the pressure relief valves. Also don't use higher pressure than what is required for your project. 6-7 bar is more than enough. Again well done for the great explanation. I hope you are teaching this in school/university setting. A final word if the budget allows it its better to use metallic piping for this project it will literally be full proof for compressor use.

You go Girrrrl!!!! Your are brilliant and will swallow this world! Let me know if you have built any air cooling dry system solar powered or any low energy consumption dry way to stay cool in a 42C humidity summer! Apparently you are at least half way through 👏👏👏👏👏👏

Great idea good job

I may just have to build one if these very cool idea

GIRL POWER! Great videos. Sorry you stopped making them. Subscribed for just in case. Aloha

Extremely good vid, Hannah. the one thing I would caution you about, however, is leaving the key in your lathe's chuck. Sooner or later you will forget and leave the key in the chuck after you've tightened it on a workpiece. when you turn the lathe on, the key will either be thrown with considerable force or it will remain in the chuck and smash into the lathe ways, causing a lot of damage. Make a hanger for the key and develop the habit of always putting it there. Happy DIYing and stay safe!

well young lady ........... I'm impressed ........... nice job

this is so great!! thank you !

I really liked the how it works part of the vid. Hannah, you are correct in getting rid of the humidity to help control sand clumping and stopping up your blaster. However the real problem is that you are using sand. Some other medias don't have this problem. I usually spread the sand onto a tarp and leave in the sun to dry, then screen out the junk before using. If I am recycling the sand, I also screen out the fines into another bucket to use for finer sand. I assume that you are going to paint your VW and sand blasting cases problems here also. Fine dust buildup in crevices is common to all types of blasting and can cause the paint not to stick. If you get out your magnifying glass and closely examine the blasted surface you will see tiny grains of sand actually embedded in the metal Some say that this is silicon and will cause problems with some paints. Cure is to use sandpaper after blasting to knock these off. Now for the real problem with sand. I started to say this on one of the other videos, but I didn't. Sand dust causes silicosis. Irreversible and ultimately deadly. Google it. Some other medias don't. Blasting cabinets solve the problem by containing the dust. I assume that you are using a respirator under your hood The hood protects your eyes and skin but does nothing for your lungs. And it is hot. A solution that i like a lot better and that can also be used while welding, painting, or any time you need it, is outside positive air pressure. It involves an oil free air pump/fan, a long flexible hose fitted to your hood and set the pump some where where there is clean air. I set mine inside by the air conditioner/heater. I droop the hose down from the ceiling in the work area so it is out of my way. The positive pressure in the hood keeps the dust out, provides a cooling breeze across your head, and keeps the window from fogging. I tried to make a homemade one from 4" flex duct and a 4" fan but it didn't work too well and was cumbersome. So I bought one from ebay with a 120v tubine type fan and 100' of 3/4" light weight flex tubing and quick disconnect hood connectors. Works good but the fan is noisy in the house, so a remote switch to turn on and off is nice. About $250 10 years ago, $400 now, but you can easily spend 10 times that on better systems. I know its expensive, but worth it to my lungs and comfort. Can also be used to blow up air mattresses, boats, and beach toys quickly. Works pretty good for light dusting as well, not as good as an air line. Scuba compressor would work if you have one. This would be a good DIY project for you. You could run 1" pvc out to your work area/areas and then quick disconnect adaptors to your flex hose Google "positive pressure respirator system" Here is one similar to my cheap one www.ebay.com/bhp/supplied-air-respirator

My second attempt has lead me to a simple discovery. This time, I was able to properly size and seat the 3/4" inlet pipe and the 1/2" outlet pipe, but had not yet reached the step of gluing in the elbows. After staring at the 2" Tees for a bit, I considered rearranging them so the inlet and outlet stab out of the tops rather than the sides making the entire assembly resemble the letter "H". Further consideration of this lead me to find that a simple straight coupler, or not even cutting either of the inner pipes would make for a much more forgiving and simple assembly, so I will acquire the other parts I need and finish my build, then share my dryer once complete on a forum with photos and link back to this video both ways to pay my respect to Hannah for originally sharing such a great idea with us. I'm stoked and can't wait to dry some air!

Very Very entertaining and I bet you are driving that buggy to college by now.

great vid!

Well done just made a copy of it an it works perfectly thank you what a genius

I made a dessicant dryer out of some steel box section with copper pipe running through it. It holds 1 kilogram of indicating beads. I'm looking for a way to scale it up and maybe a way to de-hydrate them. Putting them in the garage microwave works surprisingly well I've found, but the odd one gets burned. Great project. Thanks for posting.

If only my 16 year old son would be so enthusiastic in my work shop I have so much to teach him and would love to see him so confident in making projects like this, however mine is just a "Pipe dream" :-(. well done you !!

Oh man, now I have a new project. Thanks for the info.

Pretty and clever x

Your a pretty tricky and smart kid kido well done :)

Nice work

Thanks Kieth Noneya. "prices". In new Zealand these prices are a dream. We pay depending on supplier 4 to 6 times what you pay . Good video even with the theatrics. I reglary watch your videos.

Great Video, amazing tutorial. Water (moisture) in the paint is always my problem when doing an automotive painting for cars and bigbikes, perhaps I could invest on this project first before investing to a ready made one. I love doing projects, that's all, and I think this is one great project to build and try.

where were you when I was a kid. nice skills.. havent gone through all off your videos yet...have you tried powder coating yet? you would like it...and its really easy. look forward to your stuff...glad i stumbled on you... B
