[@Barrysworkshop]

Nice update. I wish everyone were as good at articulating safety concerns and the corresponding mitigation steps. Risk is a set of trade-offs, and your approach seems to understand and articulate that very well.

[@Fireship1]

Looks like it's working well. You can dry those beads out in the oven or in direct sunlight and use them again when they become saturated. You're doing great work. Keep it up. Looking forward to the next episodes of Hannah's bug!

[@shadvan9494]

wow. I am really impressed. I was about your age when I started working on cars.. except I was for putting them in demolition derbies. so the welding, and cutting didn't have to be a perfect. I can't even imagine myself doing body work and fabrication at your age. Just WOW. so impressed. I am going to build one or your desiccant Dryers for my garage. In other videos, you mentioned adding safety features to your car. I would highly recommend it. As far as safety feature go I recommend the following. 1. collapsible steering column, like you mentioned before. 2. high back seats with head rests. they prevent whiplash in case of being rear-ended by some one on a cell phone, and it is a horrible way to spend the rest of your life as a quadriplegic. 3. seat belts. I think you mentioned them earlier. since your car never came with them I would recommend the 3 point harness from Corbeau. I used them in my 66 Baja bug. whey work great and are very comfortable. 4. there is a design problem with master cylinder and fluid reservoir on VW bugs. they are connected to each other with a rubber hose. they always leak and all ways get air or water in the system causing break failure at the most inopportune time. I lost the breaks in my 71 super beetle to this, I went threw an intersection and got t-boned. I was lucky and everyone walked away. but it totaled my VW and a minivan. the minivan was not a big loss, other than it belonged to some one else and my insurance paid for it. but my green 71 beetle (my wife who was my girlfriend at the time called Kermit) was gone forever. again fortunately the everyone was ok. for safety, switch it out to a bus master cylinder and reservoir. its a pain to add fluid to it. but it will save your life one day. all the Baja and dune buggy guys use them for this reason. starting a new career as a hood ornament is a horrible way to die. 5. swap the drums in the front to a disk break conversion kit. it will dramatically cut down your stopping distance. so in a emergency situation it will stop on a dime. Keep up the good work, I am glad to see someone your age restoring a classic beetle. Another good source for parts is Wolfsburg West. they are in California. They make just about everything to build a complete car from scratch.

[@rindress]

Great update thanks! And thanks for pointing out the potential danger with PVC. It shouldn't scare people away from using just educate them on how to incorporate it properly.

[@TonyAnytime]

Not all PVCs are made the same, some can't take any pressure at all. Glad you address the safety concerns with using PVC and compressed air. Great build idea I may make one for myself.

[@anonimous2451]

SCHEDULE 80 IS DOUBLE WALL THICKNESS AND CAPABLE OF OBTAINING MUCH HIGHER PRESSURES. It also is More Expensive ........ besides for painting or sand blasting 100 PSI is more than enough, unless you have an industrial sized blasting job. then you would use a much larger portable compressor that is typically diesel driven. NEVER EVER use schedule 20 pipe at all for pressurized air. It is mostly used in irrigation, again because it is CHEAP............. Remember that ol saying, "Ya get what ya pay for" ??? nicely done Hannah Bug. Safety Note: Consider your pressure duties carefully cause when PVC ruptures it explodes quite dramatically. If you are unsure of what type pipe to use Research it out and do not just take someone's word for it unless they are Professional Plumber's. And then double check the info FIRST Please.

[@wayneries5970]

Hi Hanna, I build this desiccant air dryer from your design and it works fine. Thank you for sharing, and I hope you stay young and happy your whole life. Blessings.

[@michaelcangley1868]

Very, very Nice Job!!! I am wanting to to build a Desiccant Dryer System for my new shop and decided to surf KZbin for some fresh ideas. Yours is by far the best design out there and, if you've seen the others, I think you're smart enough to know why. I have been an industrial maintenance technician for 40 years and have been fighting moisture in massive compressed air systems my entire life. I even worked for Ingersoll Rand for a brief while, where I learned a lot about keeping compressed air dry. Some of the desiccant dryers they make take 4 tractor trailers to haul! By the way: The first chamber of your dryer will work better if you would stuff it full of wadded up fiberglass screening. It gives it kind of a coalescing effect. Desiccant dryers used in industry are made like twins. One dryer will be in the operating mode while the other is in the drying mode. This way you never have to replace the absorbed consumable. You simply switch the dryers automatically, and, in your case, keep on sand blasting! I have built a couple of dryers like this. The first used a small amount of the compressed air to dry out the desiccant chamber. It worked great, but, you are wasting compressed air. And as I'm sure you"re aware, compressed air is leased efficient way to power anything. So why waist it? The second employed a common hair blow dryer's warm air output to dryer the chambers. (Don't use a heat gun. It will melt the PVC pipe.) It dried the chamber in roughly a third of the time while saving on the compressed air. I have a challenge for you: Add another desiccant chamber to your dryer and a little automation. You'll have to come up with a way to divert the compressed air and dryer output back and forth. Or, like a friend of mine did, use two hair dryers. It's actually very easy and inexpensive. the automation is a little pricey but all the fun you'll have doing it makes it worth it. There are two different way to key your diverter actuators when to make the switch: Timers or moisture sensors. You can find both all over the internet. I used moisture sensors. Timers required simple programming.(I guess the moisture sensors do, too.) You'll need to tract run times to find the duty cycle of your individual chambers. I guess it really depends on the resources available to you. I hope you're up for the challenge. Good Luck!!!

[@romulus1969]

great that you addressed the PVC controversy. Something I haven't seen is the difference between PSI ratings for gas and liquids PSI between water and air (gas) are different animals because of compression. Still awesome and obvious lots of common sense in all your videos. You and your producer are awesome.

[@superkickcity1610]

[@guywihn1658]

good to know it's working perfectly! seeing you change out the beads makes me think a 45 degree or wye fitting instead of the elbow would make the filling go a little faster. something I wouldn't have otherwise thought of. thanks for the update ;-)

[@richardblanchard2743]

I worked in a shop that had some PVC airlines, 3/4 inch pipe. It worked fine except once when some metal fell against it and it exploded causing an injury to one worker. Your use in sandblasting shouldn't require high air pressure so lowering your regulator will make it safer. I am using PEX in my shop now, it is a softer plastic but still not recommended for compressed air. Great job on your videos. I can't wait to see what you come up with next.

[@SgtJoeSmith]

Richard Blanchard only iron pipe for me in my shop. But I'm using 80 gal compressor that pumps to 175 psi. If someone just want quick and cheap airline system in their garage screw eye bolts into wall studs or ceiling and run air hose through them.

[@arturobolanos9080]

Very well designed. Well done. Your Dad or Mom has a lot of tools. The apple doesn't fall to far from the Tree.

[@garywinters2282]

Fantastic Hannah, thank you for addressing the safety concerns!

[@terrymilam5692]

I kicked this around for over a year watching several videos of people who’s design didn’t give me much confidence as this one and finally built it. I’ve been using it about two weeks now and it works great, the first chamber doesn’t trap as much water as I’d hoped I drained about a half cup out of it today and the other side top third has changed color but I’m getting no water at all out of my air tools or glass bead machine.

[@underourrock]

I'm glad you provided a followup. You've mitigated the problems to a large degree, but there is still a large degree of residual risk: You don't know how quickly PVC will degrade over time. Maybe replacing it after 1 year is good enough. Better to just build it out of something that is inherently safer. Also, if your desiccant is the same silica based stuff that comes in all those little tasty "do not eat" packets, try baking your used desiccant in the oven at a low temperature to drive off the moisture. This might not bring back the original color that is used to tell you when the desiccant is used up, but it is easy to dry and reuse your desiccant. You could keep one batch in the dryer, one batch that has been baked and resealed in an air tight container. Anyway, you have great presentation, your videos are well thought out, and you speak well. Keep it up, just please consider that although you have given a lot of thought to safety, just don't let that make you feel like there isn't room to reduce the risk even further.

[@underourrock]

Brian Hanson I'm not sure that applies here. I'm talking about plastic degrading and being dangerous. It sounds like her setup is well thought out and she's mitigated the major concerns. On the other hand, It should be possible to build this out of copper, though you don't get the pretty window. It would last forever and you could incorporate a 2" vertical expansion chamber to collect water and vent it out the bottom with a drain valve. A couple of threaded ports would make it easy to check and refill.

[@L1ne3]

I just found this youtube channel. You are awesome! please do more vids. I ran out of your content, and your content is awesome! Also, a burst disk rated below the tolerance of that clear tube wouldnt be a bad idea.

You know if you really want to have fun with everyone get a pressure relief valve that blows at like 110 PSI. Without danger there is no safety need. Your doing the right stuff.

Thanks for posting Hannah, I was wondering how well it worked and how long it worked. I live in the south so I think it won't last as long here, but i'm sure it will do the job. Best Wishes n Blessings Keith

[@HiTechDiver]

I like your video. You're a very bright and inspiring young lady, and cute I might add. If I might suggest something, when your system fatigues and you replace it, consider using a Y fitting in place of the T and 90 degree elbow for the desiccant fill opening. One less part, and the desiccant would flow into the tube much easier.

[@jafinch78]

Wondering how well this and others similar designs are holding up. Surprised me seeing some run PVC for the air lines in shops. Was thinking Sch80 if you wanted to be safer. Thinking one of the intercooler designs like YT channels "Nikita's Lab" and "Guns and Garage Gear" prior and or a vortex type using an inverted welding gas tank would help dry as well prior, so less dessicant changes and processing. Nice job!

[@NowWhatShow]

I agree with the guy below me she is incredibly smart and I’m a engineer and half of what she talks about literally blows me away with knowledge. Keep it up and never change

[@brucetrue]

You are super smart. I have a dumb question. Could you dry the air before it is pressurized. That is the air would be dried before being put in your pressure tank. The pvc wouldn't be under pressure. Also, water in the pressure tank wouldn't be a problem anymore.

[@hannahsbug1520]

Hi Bruce, brilliant question! If you live in the dessert, that would possibly supply enough dry air to supply the air compressors. But the volume of input air is so massive, you would need a massive amount of desiccant in any other climate because desiccant needs contact with the air for enough time. Your house would need to be essentially a large humidifier to provide enough dry air, but this would be highly impractical

[@johnevon3030]

@@hannahsbug1520 Wait, you respond to a brilliant question but not the most important, what happened with the build? hannah built a gantry and end of show, there are all sorts of horrible ways to end a great series, what happened to this?

[@mrstanskaggs1]

The PVC stress factor is not related to the pressure it sustains, it is related to flexing and relaxing repeatedly. The PVC can shatter at pressures which are deemed very low due to this expansion fatigue. There are other materials similar to PVC that can be used, but tend to be a little pricier than PVC. PVC tends to be sensitive to temperature as well as expansion, so care should be taken to watch thermal stress too as compressed air tends to be warmer due to the heat of compression. This has been an interesting video set, and actually is some really good ideas to pursue in my opinion. I would definitely look for a different construction material though, or use some reinforced sheathing such as Kevlar or something around the PVC at a minimum. If you have seen the results of high pressure sending shards of PVC, I am sure you can see its not something that should be shrugged off. I would suggest putting the setup you have behind a 3/4" -1" plywood panel possibly so that any explosion might be stopped a little (The shards would most likely penetrate 1/4" plywood with ease). Its really a clever idea, so don't give up, and just address the safety issues as a path to take.

[@FredFlintstone718]

Hannah, you're doing a great job with your videos! One question: Does the water trap part collect enough water to make it worth the effort? Or might it work well without the water trap part, and instead just recharge the desiccant more frequently?

[@Phil454LSX]

Awesome dryer, I like the user friendliness of changing the desiccant out. However, the PVC aspect is kinda sketchy. I just bought a dryer that is about the same size from MSC and it was just over $300, rated to 30cfm and 210 psi. That beats having to make a new one every few years. It isn't quite as easy to change, but I won't have to replace it or worry about it exploding as I run 150 psi through it.

The company I work for used PVC pipe for their air system for the first twelve years I worked there . In all that time it only ruptured maybe three times and of those three times no one was hurt , but it does scare the holy crap out of you when it does go lol !!!!

[@Z71Ranger]

You all are lucky... I know a man that lost an eye from a two year old PVC air system... I'm really surprised your company has continued to use this PVC system after 3 ruptures... I guess they want to just pay out 1000's of dollars when someone gets hurt... Because it's just a matter of time... Call OHSA before someone gets hurt or killed it could be you...

[@snoopdogie187]

If that company wants to be cheap, they should at least put something around that PVC. Even some thin metal will take most of the force out of the the PVC pieces. Then again, when its a company, down time of a unit costs money, unless you have a backup system, which is just extra money, and yes 3 times in 12 years is a lot, but each time costs more money, and eventually the cost of the proper system will be reached. Don't forget, to rebuild the PVC system has other costs like the labor that goes into it. Its just a bad idea for a business to do something improperly, unless for a few limited reasons.

[@johnsont963]

this was 20 years ago when everyone used PVC so I dont think anyone really mind fucked the shit out of it back then...and no 3 times in 12 years is not alot............you must not be familiar with manufacturing and OSHA back in the late 80's early 90's....

[@samp1394]

If you use the right pvc not the thin one. And use a compressor that pumps around 140 psi it will not rupture. I have it in my shop since 1974 no problem.

What humidity were you working at/how full was the water trap. I plan to make a condenser out of copper tubing and leave the door open for regfigeration if it is not enough. Wondering if it would be a viable alternative.

[@Kustomgadget]

Schedule 80 PVC (available at electrical supply outlets) is much stronger and also UV resistant. Even so it might be a good idea to build a cage around it. Also a suggestion I believe might make it better is by adding a restricted orifice to the first water trap the air would be cooled and condense better. It's basically a refrigeration principle. Perhaps you could test the concept and post the results.

[@marcphillips1020]

Too cool. Smart young lady, keep up the good work!

[@0x73V14]

If you add a ball valve at the fill and empty ports you won't have to wrestle with the cap and it will be less leak prone. Also a $8 sheet of osb cut and hinged would provide an adequate safety cover, it would be open above and below so a failure would just mean beads everywhere

[@reynaldobonilla9881]

Great video. God bless you

[@rosewd2]

You should have metal piping and a drip loop setup prior to the drier. Saves on beads. Tip tools sells the kit but you can just look at it and make your own from common iron pipe fittings. My water trap stays dry with just that. Make more videos :)

[@bentleynut1648]

I noticed that the right pipe is under strain and moves when you tighten the plug cap for the desiccant. I would suggest putting another metal band lower down the pipe so it does not flex when you tighten the plug cap. Any flexing of the pipe will fatigue the pvc particularly at the joints making an explosion more likely.

[@Sevalecan]

You said your clear PVC was rated for 120PSI, but the "Excelon R4000" 2" PVC I'm finding in ebay is rated at 390 PSI (which is freakin' fantastic)... What is the source of this inconsistency?

[@duffahtolla]

The smaller the pipe, the better the pressure rating. Excelon R4000 2" dia PVC is listed as having 140psi max. The 390 PSI Max rating is only for the Excelon R4000 1/4" dia pipe. I think your ebay seller mixed up the ratings.

[@Sevalecan]

Just checked another site for ratings to confirm and it seems you are correct, sir. Thanks!

[@scottwillis5434]

Also look at pressure rating vs. temperature.

[@mrstanskaggs1]

also check stats in that pressure max rating is not the same as the rupture rating which is normally about 10X higher than rated max rating. I believe that is a regulation too.. will have to validate that though.

[@pcka12]

Those pressure ratings relate to liquids (principally water) when high pressure vessels such as SCUBA cylinders are tested they are filled with water and placed in a water tank, then the pressure is applied because since water is pretty much 'inconpressible' no explosive decompression can occur. These PVC pipes are essentially 'water vessels' if you fill them with compressed gas (which they are not intended for) you are potentially creating a bomb since unlike the malleable metals traditionally used for air pressure pipes the do not 'plastically deform' but shatter, this looks like a nice idea, but I am certain that I won't be using these materials I am afraid

[@albertedwards6620]

Transmission oil cooler for Dodge Durango $50. Various compression fittings and soft copper tubing $15. Room fan - most likely free. Plumb pipe from head to tank to first go through trans oil cooler.

[@Mr1stnutt]

yah pre-cooler is always better than after cooler= no moisture in the tank no corrosion no huge metal bomb 20 years down the road

[@siggyincr7447]

Rusted steel tanks just start to leak, they don't explode.

[@jeffowens8722]

Still on the fence about the pressure ratings. PVC is rated typically for water pressure at a much lower temperature than compressed air. Those ratings drop as temperature increases. I love the design but just unsure of the high pressure at compressor temperature. Anyone have further knowledge in this area?

[@monteporche5552]

The bigger issue is that water is not compressable. So, if you put a cubic foot of water into PVC pipe at 150psi, and the pipe breaks, you will still have one cubic foot of water trying to escape. If you put one cubic foot of air at 150 PSI into PVC pipe, and the pipe breaks, you've got something like 10 cubic feet (at 15 PSI---close to standard air pressure, I'm sure my math is off) of air trying to escape. This will cause a much more violent explosion. To make it easier to visualize, picture two identical balloons, one is inflated to a diameter of 12 inches. The other is filled with water until it has a diameter of 12 inches. Pop both of them and compare how they rupture.

Hannh, Thank you for your many videos. It's great to see a young woman involved in STEM and being a Maker. Hacking technology is a great activity. I'd encourage you and anyone to go as far into this arena as you want. It's time for the other shoe to drop.....thunk...on PVC for a pressurized air dryers. It's well documented these designs are potential hazards to life and limb. Your methods of operating your dryer design reduce risks but can't, as you expressed, reduce them sufficiently. There remains in KZbin's public settings those without such sensibilities who aren't as careful and astute as yourself. It's possible to design air dryers that utilize other materials & designs. I'm working on a few designs for my own use. I believe you would be the best designer & voice for your audience. I hope you'll provide new video production examples of your talent in this area. Cheers, John S. Wolter

Hannah, how old are you? I'm wondering because your channel is technically (both content and production quality) better than any I've watched from anyone under 25 (I was going to compare you to guys since they have most of this kind of content, but that's irrelevant, of anyone guy or girl), and I'm guessing that you're much younger than that. I'm very impressed as are others and I'm sure that I'm not the only one wondering. PVC. I know that you think you've addressed the issue from a technical perspective but I assure you that you are not as safe as you think: 1- your compressor bank is capable of generating 125psi, and you could change the regulator setting (say to use a grinder or impact gun) and forget about it or the regulator can get jammed, even if that doesn't happen the general engineering safety margin for this kind of thing is at least 2x, so I wouldn't use anything rated under 315psi (I think the closest PVC pipe rating is 330psi). 2- the pressure rating on PVC pipe assumes it's new and perfect. Scratch it, hit it, expose it to UV light (you mentioned sunlight but your fluorescent lights will eventually affect it), temperature extremes, pressure cycles... all weaken it and make it brittle. 3- glue joints in the stuff can be finicky. If you take a second too long they seem to stick together in the wrong place, and don't get them perfect the seem to come apart or leak. In Ep. 11 you didn't primer a number of the joints. I'll bet that those come apart before our PVC shatters. With a lot of force- I used to make air cannons with the stuff and had a design that could shoot a potato through 2 sheets of 3/4" plywood, a PVC endcap is quite a bit harder than a potato and you are quite a bit softer than 2 layers of plywood Again, I know you think you're being safe with this, and most likely you'll never have a problem with it, but I assure you you've built a potential bomb. I had a friend of mine, a mechanical engineer, design and build a similar tank to test some automotive components, if I remember correctly it was 3 or 4" SCH40 PVC with some end caps/cleanouts and fittings in it, all brand new pieces that he bought that week. He set it up with a blast shield so if it did rupture it could only go down towards the floor. Well it did rupture, one of the end caps hit the floor and bounced up into his face when he was standing about 6' away from it. His glasses were embedded into his face (had to be surgically removed), broke his upper jaw, knocked out a bunch of his teeth which had to be replaced with dentures/implants, and he ended up with 2 steel plates in his face and for a while they thought he'd lose vision in his eye. This really isn't something to be taken lightly. Finally, your design- short version, if you made it out of steel or soldered copper it would not only be safer, but for the first water separator to really work it needs to dissipate heat. Something metal that conducts heat would work MUCH better, or even plumbing a separate air tank in the hose some distance away from the compressors would work. Harbor Freight used to sell a desiccant filled dryer (about 4 foot long steel tube with fittings and mounts) for cheap (I don't see it on the site now) or google "Franzinator" for a simple design that is safe and easy to build (dig up the original drawings, they were much better than the thousands of versions made since then). In my case I run my air into a large tank, then through ~20' of 1/2" lines to a separator/filter like you first showed, into a desiccant dryer (originally a welded franzinator but I had problems getting threaded fittings for it that didn't leak and at some point realized that I had more in fittings then it would have cost to just buy the dryer from HFT) and finally into a motorguard "toilet paper" filter. That combination gives me plenty of very dry air which I use for painting, sand blasting and plasma cutting. Otherwise keep up the good work and good luck with your project! I'll likely show some of your videos to my 4y/o twins. They, especially my daughter loves helping me work on the race car, fix engines, all things mechanical, and both her and her brother love helping me with electronics. Both love watching various builders/automotive youtube channels with me, and I think they would love to see someone closer to their age doing this kind of thing than someone my age. ;-) I want to see you get into some of the math, when I was 12 my I wanted to build a go cart so my dad (an engineer in the space program) handed me "Mark's Engineering Handbook" and helped me learn some concept of calculus so I could figure out how many HP I needed to get the acceleration I wanted (I wanted to be able to out accelerate his car). Sounds like one of your parents might be a bit like mine.

More difficult to find and more expensive but much heavier, is Schedule 80 PVC pipe and fittings.

[@ForbiddTV]

But you won't find schedule 80 in clear.

[@TheMarcusGomez]

max pressure is higher than advertised. for liability purposes.

I need one of these, it's times like this I wish I wasn't an idiot and had a clue what she was talking about. Oh well...
