Thanks for watching this video. Now that this video is a couple years old a couple of the same questions come up a lot in the comments bellow. I've made a part 2 that covers the question you're about to ask. :) Here is a link to part 2 kzbin.info/www/bejne/Z5bIn4mEg6Z7l5o

[@BigDaddy-yp4mi]

expanding gas cools....the entrance to the copper pipe also has a throat expansion. That's where a majority of your action is. Placing pipe size step-downs right before your drains and a step-up right after a drain will make a huge difference because air that expands cools down instantly from pressure drop which causes it's moisture to hang on whatever surface in that immediate area that it can. I'd suggest some form of washable media, glass tiny marbles and such put right in-between the step up & step down to give more surface area for moisture to settle on, drawing it out of the air. There's a lot of thermodynamics and Bernoulli's principles at work and you gave me the idea on how to design the perfect setup to provide continuous clean air. Thanks man!

[@tinnedanger]

Just a suggestion... Plumb your condenser directly from the compressor pump through the condenser then into the tank. You'll have much less water in your tank.

[@l33b80]

Yes! this was gonna be my comment also

[@andrewfredrick7017]

I did exactly that using an old a/c evaporator from a whole house air handler.

[@satxsatxsatx]

When I finally figured out the sequence, I was amazed to find that his condenser was after the tank rather than into the tank Dry air into the tank allows the tank to last longer since probably it is not coated,

[@saiae]

I came here to say this. The cooling/drying loop is in the wrong place.

[@peetky8645]

YES, that is the appropriate way to do it.......also, smaller tube is better because air volume/tube surface is lower, although air speed is higher.

[@IRDeezlSmoke]

I too have a cnc plasma table and have been running this configuration for 4 years. 1" iron pipe with ball valves like yours. It works. Period. It removes and amazing amount of the water and cools the air quite well. I have a larger table than you, and also include a refrigerated air dryer in my air supply loop. It does very little on short jobs, but on high amp, high air usage jobs, the compressor runs a lot and the refrigerated air dryer is needed. Made a huge cut quality improvement.

[@fiskfarm]

I made one like yours about 25 years ago and it still works great. No issues with the black iron pipe at all. I mounted mine to a concrete wall for extra heat sink. 👍

[@incolink]

Iron makes a alot of sense Ive been pricing up the copper recently and I'm up for around 500$ i can put a condenser radiator in a refrigerator for half that price

[@Rodzilla-du3pp]

I noticed the clamps you used to mount the copper pipes to the wall look like steel. If they are you may run into problems with galvanic corrosion. Eventually the steel will react and create a hole in the pipe where steel is contacting the copper. You should change those out to copper or brass clamps and you'll be good to go. Just thought I'd let you know.

[@BeckTools]

Yes, I forgot about that. good point

[@cybersurfer2010]

Just add some insulator so there is no contact between the copper and steel...

[@AN-kg4ei]

@@BeckTools pipe wrap or a cut rubber hose will fix that....

[@SuperNolaguy]

Old Plumber here, wrap cotton cloth electrical tape around copper tubing where clamp makes contact. Also mutes the tubing if there are any harmonics. 😉

[@MrTheHillfolk]

​@@SuperNolaguy went thru the basement and did this recently. I have an LG washer machine ,and when it begins filling it kicks the water on and off at first in 1 second spurts for whatever reason the silly microchip wants it to for about 20 seconds. (actually I guess they're trying to figure out the load size somehow from what I've read ,it's one of those units that washes and dries all in the same basket). Talk about annoying squeaks all over as it cycles, but I fixed em as you described.

[@randykovalenko1236]

Mount the coils on two horizontal 2 X 4’s to get them off the wall for more air contact. And yes use copper mounting strips.

[@ouimetco]

I thought your video of really good. Natural and easy to follow. Like a normal working man. Not staged like most videos. Appreciate that.

[@DCS_Garage]

You could T all your drain ports at the bottom together with a single lowest horizontal run if you slope the horizontal pipe downwards then you could have just one drain valve. That's about the only improvement I can think of to the flow and ease of use of your system. Looks good.

[@Tkaya460]

And then putting a solenoid valve or other electronically actuated valve on it so you could add automation to the draining of the dryer.

[@chucknSC]

Nope. That would allow air flow to bypass the vertical tubes. That air wouldn’t have been cooled and thus would carry humidity out the outlet.

[@JoeGraves24]

Going from 1/4” tube to 1” tube is actually a 1:16 ratio in area. That means the air velocity ‘practically’ slows down 16 times. That’s an amazing amount of surface area for condensation to happen. I love the overkill!!

[@BeckTools]

It works really well! I still have not had a single drop of water in my two SMC water separators since I installed this months ago.

[@miguelpadron5984]

Would it work if I make it out of 1/2

[@JoeGraves24]

@@miguelpadron5984 it would likely work but you’d need 4x the pipe to equal the drying power of this setup.

[@Jcreek201]

It's a 16x increase in the cross-sectional area of the pipe, but not a 16x increase of the internal surface area. It's only about a 4x increase in surface area. The real advantage is the pressure drop due to the larger diameter pipe causing the air cool and moisture to condense.

[@JoeGraves24]

@@Jcreek201 absolutely correct on the surface area. I was making a comment on the cross sectional area because it slows down the velocity of the air by a factor of 16, thus increasing the exposure to the increased interior surface area. I used to be able to figure that out with fluid dynamics once upon a time. Thank you for the correction!

[@ThyAnarchist87]

I would think having a large down section above the valves would allow a spot for the water to build up that isn't inline with the air flow preventing the still water from being carried along with the air. Basically just have a section of pipe run straight down off the T before adding the valve.

[@weathertrainsrandomniss1083]

Stumbled on this video. A dryer was not on my list but now it is. Cheers from Wisconsin.

[@BeckTools]

Thanks for the feedback. :) I've made a follow up video with a lot more information if you want to take a deeper dive into this topic. Here is a link to part 2 kzbin.info/www/bejne/Z5bIn4mEg6Z7l5o

[@1ton4god]

I'll tell you something that's helped me tremendously. Your air compressor sucks air from inside the shop. When you open those you atomized the air and moisture coming out of there. Then your air compressor in your shop sucks that are right back in. I will tell you if you exhaust those outside you will benefit tremendously from it. Just run some lines tying all four of them together and then one exit line going through the wall out above the roof you don't want them asking on the side of your building. Also you can tie the tank drain on the bottom of your tank into that also. Hope that helps period also will eliminate the staining on the wall:-). I am waiting on my langmeyer crossfire Pro should be here sometime before the end of the month.

[@BeckTools]

yeah my Crossfire pro also creates a crazy amount of steam. It would be nice to put and exhaust hood above my table and send that steam and toxic fumes outside as well. After about 15 minutes of cutting the water in the table is so hot you can barely put your fingers in it to pull our parts. The 1 inch tubing works so well despite all these things it still removes 100% of the moistures. My SMC water separators have not collected even a single drop since I installed the copper system. I still want to vent the toxic metal fumes. That's way up there on my list.

[@1ton4god]

@@BeckTools yeah that's why I'm a little nervous about setting mine up in my small shop.

[@91rss]

up north a guy posted his install using old hot water baseboard heater piping with the fins on it. woks amazing and got it at a scrap metal yard. also on the intake you put a second filter , It stops that sucking noise so you can stand next to the compressor and even talk.

[@michaelheurkens4538]

To prevent the galvanic corrosion from the steel clamps, wrap several layers of electricians' tape on the copper. I would also recommend clamping only top OR bottom horizontal tubes to allow for the bit of expansion/contraction of the tubes. Verticle tubes pose no problems. For those wondering if copper can withstand the 150psi, I have been taught that properly soldered copper joints AND the tubing sidewall can normally handle up to the 300psi range. This allows for slightly frozen pipes without rupturing. Cheers from Alberta, Canada.

[@BeckTools]

I cover this in part 2 if this video. :) It's in the pinned comment.

[@butchs2337]

where i Live it was to hard to get 1" copper tubing so i went with 3/4" and about 60' total length, the compressor is in about 90 degree room upstairs here in South Florida, the lines go downstairs to the copper tubing that is in a 70 degree room and then goes into a 50 degree room where it is used to run the equipment, i also I put a cooler and water separator on like many others have done on youtube, the cooler takes out a lot of water, i have not yet hooked up the copper tubing to the system yet but very soon it will be done, when it is done i really expect almost no water in the lines, thanks a lot for the video it helped me a lot, i did all this at my job where i work, we were making so much water compressor works a lot, it is a 60 gal Husky 11.5 cfm

[@BeckTools]

Thanks for the feedback! :)

[@m3chanist]

Yes the larger tubes have a greater surface area, BUT they have a much worse surface area to volume ratio, which is the significant thing when you are trying to remove heat from that volume. Put plainly, a number of thin tubes of equal total volume to a few larger tubes provides much more surface area for that volume to dissipate heat through. Many thin tubes are significantly more efficient at removing heat than a few thick ones.

[@rexhartung2385]

I've been a car painter for over 40 years the thing I do is I just crack the petcock leader valve on the bottom of the tank till you hear a hiss and I never have any water build-up in my lines at all😊

[@ianmoore525]

If I was making that, I would have the pipes running horizontally and slightly stretched so there is a slight fall on each run, just one drain in the bottom. The place I worked at in AU, who manufactured CNC plasma cutters and routers, the budget option for plasma cutters ( rather than a refrigerated dryer) was a toilet roll type dryer, toilet rolls don’t actually work as well, the proper ones are brown and different material. They work remarkably well.

[@williamstock3007]

Do you know how well these work in warmer climates? Would these fail to work in 40 Celsius?

[@Zappy1210]

I have used an air cooled system in the past, they work ok. I now use water cooled system and it just works much better. Mine has 50 foot of 1/2 copper coiled into a 10 gallon barrel with a relief valve at the bottom in the water where water inside the line will collect and is pushed out automatically every time the compressor airs up. You just hear bubbles for 2 or 3 seconds or so after the compressor shuts off. No valves to open and close constantly, just add a bit of water now and then. I also run a single stage air compressor dryer for good measure but it has never shown any signs of moisture where when I ran air cooled the dryer still got a bit of moisture in it. I have run this for about 5 years now and have never had any moisture at all in my tank. I actually scoped inside the tank last summer, it looks shiny and new inside, no rust whatsoever.

[@ryanbard9354]

What kind of relief valve did you use? I'm looking into doing a water cooled setup as well.

[@Zappy1210]

@@ryanbard9354 I don't recall where I got it from, but I ordered it offline for about $30.00 5 or so years ago. Think it was just a simple 120 PSI pressure relief valve. They had them from like 50 PSI all the way up to 200 PSI. I recommend getting it brass so it doesn't corrode under water, and get a bucket/barrel with a sealing lid to help keep water from evaporating. You'll have to leave a bit of air gap so the relief air can escape. I just have a 1/2 hole in my lid for that. I typically have to add about a gallon of water every 2 weeks or so to keep barrel full, little more if I use the air more than a normal week.

[@ryanbard9354]

@@Zappy1210 if my compressor motor shuts off at 175 I should put in a 175 relief valve then? I've been scouring the internet trying to find info but not many people do water cooled setups (or they just don't record and share the info)

@@ryanbard9354 yes 175 would be your pressure relief valve. They typically have an adjustment screw to adjust 5 or 8 PSI for blow off.

@@AlessioSangalli I have two additional commercial grade moisture separators down stream. After months of running they have not captured even a single drop of moisture. The on filters down to .01 microns. Every time I crack the valves on my copper cooling system I get lots of water. I know it's anecdotal but that doesn't mean it can't be true. It just means I don't have a measured value :)

[@randygerman2176]

The condensate drains do work better located on the opposite leg. The moisture will always be running down the pipe walls even when there is no flow and being heavier than air when there is flow it will tend to go in a straight line towards the dirt leg trap while the air will make the turn at the tee. Plumbing and pipefitting 101.

[@realmetallurgist8493]

I built one of these years ago, using no more than three feet of 1/2" pipe. I have a little squirrel cage blower that blows on it. Works perfect. If the tube stays cool at the far end, then the apparatus is doing it's job.

[@Chris_In_Texas]

Ideally you would want the cooler between the compressor itself and the tank. Otherwise you are just pumping wet air into the tank, drying the air before storage is possible is the way to go. 🤠👍 That is where you can take a old compact fridge and use coil of tubing with drain. Then use bucket of water in the fridge and have it cooled down as well. It will help take out the heat much better than just air to air inside the fridge.

[@oBseSsIoNPC]

Very nice build! Never thought of doing it this way, but I am going to try it. Only advice I have for you. Build a box, cage or separate room for the compressor. There is an extremely low chance, but the tank CAN fail and it will send shrapnel through the shop. Those large compressor tanks are serious bombs. I never trust any of them and at least have a heavy metal cage around them. The explosion will still rupture your eardrums, but it won't send pieces through your body as easily. 90psi filled truck tires send men flying 20 ft. When they come apart.

[@wheels-n-tires1846]

A great idea. I took a 30gal 200psi compressor, and plumbed it into the 35gal tank of my old compressor. It only sees 150 psi since it's rated at 165, but it's plenty, and i almost never have a low pressure problem, and most of the condensation is caught in the second tank. A drain loop in the steel pipe output catches pretty much anything left. But having said that, I could see adding a copy of your setup in the future!!! Now to just over engineer your setup a tad more, and link all the valves to a single handle...😅

[@Booze_Rooster]

I just went through this nightmare. Finally got a decent compressor of my own and attempted to use different filters to reduce moisture using a gravity sandblasting gun on a truck axle. After several unsuccessful setups, I ended up getting an old DeVilbiss 803643 filter from a coworker. Got a new element for it and zip tied it to my compressor's frame. Ran a 30' spiral hose from the compressor to the filter inlet. Running the $0.75 harbor freight inline plastic filter just before the swivel fitting at the gun. Before I'd get about two hopper loads in before moisture started creeping past all the dumb transluscent dessicant filters I was using. The cheap plastic ones on their own were getting me two or three hopper loads each. After setting up a long enough hose for the water to condense, I can run my blasting gun practically indefinitely. Every bag of media I go down, I dump the tank and filter drain, then let it all charge back up while i swap the cheap plastic filter at the end of the hose. Not going to be my final setup but it works for the budget and space I have right now.

[@darrenfrith3958]

These work excellent. The 1" tube is very smart. You can also make a pre-tank separator out of a vehicle condenser and a small tank or drop tube with a valve on the bottom. Basically you take the hard line directly from the compressor pump, attach that with flared fittings to the AC condenser, attach a T at the outlet of the condenser with a valve and a drop tube along the back of the main compressor tank and plumb back into the original tank inlet location at the top. Attach the condenser to the fan/pully cage of the compressor and viola, you keep water out of your main tank as well.

[@oldowl4290]

And the other main benefit is cooler air is more dense by volume. So if the air is sufficiently cooled before entering the tank it actually holds more air at the same given pressure than hot air at the same pressure. So by cooling and drying the air first before it enters the tank you make much better use of your storage tank.

Sorry, but hydronic baseboard copper(Slantfin, etc) is generally very thin and rated for only 30psi. Most such systems run only 12psi in service.

[@anonimous2451]

Nice Set up. 1 critique if you will and perhaps a better mouse trap.. The Catcher tubes should be 4-6" long cause the 2" tubes are a lil too short IMHO. Other than that liked you're idea of the turbulence T and all. If you swap the output of your compressor to the dryer lines and then return via the Tank, you actually virtually eliminate ANY water vapor from your tank which extends its life. I personally added a double separator, macro/micro separators in tandem with an output regulator on the FIRST one and a desiccant dryer all in a single row lineup. My Plasma cutter has never seen a drop of contaminants. I also use it for painting cars/trucks/motorcycle fairings and pieces and it is flawless. I added an double oil tank with a clear glass jar for my air tools that is plug and play via a 3 way switched air flow valve to do air tool work on the aforementioned body parts. The oil is down line of the valve actuator so no danger in oil infused into my dry lines. My 2c worth.

That would increase resistance to flow. The surface area that matters is where heat moves from copper to surrounding air. That surface area is unaffected by internal sponges.

[@ironwooddesigns9532]

I'm concerned about getting high volume out of this system since your inlet line is just 1/4" tubing. I like the Tee design; you are right, that angle can help condense moisture. So does cyclone rotation like the moisture separator design. I've thought about making one of these that resides in a fridge, freezer, or even a tub that can be temporarily filled with ice water. As you drop that temperature, more and more moisture will condense out. As others have said, the auto drain for your compressor is worth its weight in gold.

The next time you build one put an upside down U or drip loop in after the valve of each stage . What you build works by gravity . So adding an upside down drip loop in will catch more water and it will double what you have now . So first stage valve then after that drip loop upside down going to stage 2 valve then going to upside down drip loop .Once your wet receiver is full of water (your tank) in super hot summer it will pay off . Winter is one thing but summer is a bit different .. Oh I will add this in as well . If you have 125 psi in your wet receiver (tank) and only using 30 psi at the other end ? Having a regulator before it hits the part that you built will help a lot . So your tank 125 psi and a regulator 80 to 60 to what you made and after what you made regulator at 30 psi depending on your needs ??? Anytime you slow something down gravity takes over . good video !!

[@blackbear92201]

Cool video. Love the 1" copper pipe idea. I wonder if you could use a "tree-like" structure for the 1" pipes, and use only 1 reservoir (any size) and 1 valve at the very bottom? Or some variation. thanks for posting! :D

[@JoeKyser]

its called a collector and yes you can use it

[@jeffbarker730]

Great job! May be a little over kill but look at results, good job sir!

[@andreiv8186]

Love this setup. Can you fit a transparent pipir down low so you can see the moisture when it builds up?

[@DayClanTribe]

Good idea to go big because that offsets the pressure drop you would experience adding that many feet to your overall line length.

[@AY-cj9kp]

Yeah, I did the same except longer copper tubes and L-type copper (not the M-type which is the thin wall regular). Works like a Swiss clock. Also, I took square wood beams 4”x4” approximately and drilled 1” holes at the copper pipe distances center to center. Then cut them along so the holes would be split. Then I clamped it over top portion and bottom portion of this copper assembly. This made the structure solid and easy to manage. Simply bolted it to the wall.

[@BeckTools]

Good tip!

[@robert5]

I'm building one. I am going to use ether 3/8 or 1/2 tube and not that tall. I'm going to mount it on the compressor in front of the large compressor pulley with the slanted fins for air flow. I am going to connect it along the bottom to one long manifold with one dump valve. It will ether work or not lol. I am still going to mount a filter and desiccant dryer along with the regulator. There is one dude who used a older ford F250 air conditioner condenser mounted on the guard in front of his large finned pulley. Might do that is I can find one cheap enough. I just bought a plasma cutter so got to get this built.

[@jdwilliams5244]

This is very helpful. I agree about getting steel close to Copper. I had a water leak in my house because a nail was 1/8" from my copper water line. Also, I think I will build a supporting frame and then screw the frame to the wall. Thank you for the video.

[@michaelmusson3593]

I did the same thing I probably spent 350 dollars on mine I used 3/4 tubing but the L tubing not the M the L is thinner and about half the price I remember checking how much pressure it would hold and it was around 400 lbs I used 8 7ft sections so gave me 42 feet for the air to cool.

[@timothyholewinski2478]

I think you have this backwards. K is the thickest, M is the thinnest, L is in between, so L is THICKER than M and should cost more...

[@Jay_the_Caffeinator]

You could put some really thin metal sheet where the valves discharge. It will help stop pushing the moisture into your drywall.

[@highplainshollarhomestead3188]

You only need 1 valve. Remove all those valves, run a header across the bottom and tee into it at each loop. Run the header and a slight grade towards a valve at the end. Solves your wet wall problem and you only have to release 1 valve.

[@15630scarusrd]

The problem I see with this is that the air will take the path of least resistance and travel along the bottom header rather than up and down through all the pipe which is where it is cooled.

[@peterd1234567890]

If you also put a regular just before this in side of the copper pipe and drop the presser down a bit expanding gas reduces temperature condensing more water

[@kk2ak14]

Very good idea man! Just connect another tank after the pipes.

[@BeckTools]

Good idea!

[@takedeadaim8671]

I realize it’s an old video but nice plan with the 1” copper. As others have said steel fittings in copper pipe and clamps are going to eventually cause an issue, the reducers and all are available in copper and a few feet of #10 copper wire would strap that down against two or three horizontal 2x4’s you get better air circulation behind the copper and eliminating the vibration saves the pipe.

[@BeckTools]

Yeah i cover this and more in part 2. Since this video has blown up the last couple days I'm going to make a part 3 showing all my upgrades since I installed this. Here is a link to part 2 kzbin.info/www/bejne/Z5bIn4mEg6Z7l5o

[@johnholzapfel4495]

Hi, What you have made is very good indeed. I would suggest as mentioned the galvanized straps need to go or at least use a barrier between the pipe and the straps.. Also get the tubing off the wall about 3/4" to promote 360 degree circulation.Consider a small fan to blow across your condenser that can be incorporated in the electrical circuit to come on with the compressor and shut off after. I live in S.Florida with 90% humidity most of the year and have had to resort to the above mentioned ideas. Cheers and 73

[@johnbladykas4885]

I wonder if just above your purge valve more longer to catch water. Next question does the copper tubing have a temperature change. Thanks for sharing your video

[@BeckTools]

Yes it does have a temp change. As it transfers the heat form inside the tube to the outside it heats up. The more humid it is the faster the heat transfer happens leaving less heat in the copper itself.

[@michaelmolter8828]

You could probably use 1/2 copper and those aluminum snap on fine for radiant heaters to get more heat flux cheaply.

[@DougsMessyGarage]

I have a CF-Pro on order. I think I might have to look at making one of these cooling rigs for my compressor

[@BeckTools]

did you order a plasma cutter to go with it? If not check out my videos on the Everlast Power plasma 82i. I ran the Razorweld Razorcut 45 for a year then upgraded to the Everlast 82i I love it.

[@DougsMessyGarage]

@@BeckTools I am gong to start with the Razorcut 45 if for no other reason than since it is the unit Langmuir sells, they will be able to provide support for it during the learning phase. If I find I need something better, I will upgrade. The Everlast is on my list of potential upgrades if the Razorcut 45 doesn't cut it.

@@DougsMessyGarage That what I did and for the same reason. :) buying a new CNC plasma table is stressful enough. Adding what seems like and un-supported devise on top of that is scary.

[@mjktrash]

I bet someone covered this for you already, apologies if so 1/4 tube = .25^2 * Pi = ~.05sqin 1" tube = .5^2 * Pi = ~.785sqin That's a 16x factor, so good job! (And going from rubber hose to copper tube is another increasing factor)

[@BeckTools]

In my head I was thinking it was 16x but I don't know if I was willing to say it in the video. hahaha. I hadn't done the math and I didn't want to spoil the video over this 1 issue. :) Thanks for the confirmation.

[@MrTheHillfolk]

I definitely need to build something like this. Im always on pops to drain the compressor but he doesnt. Campbell hausfeld 60 or 80 gallon(lol i always forget) single stage. Its in the heated part of the shop, but i usually work in the unheated area. This winter was so mild ,it was 38f for most of the time in the work area. Totally awesome to me ,as i work outside so that was almost t shirt weather to me 😂. Anyway,after 5-8mins my angle die grinder blows ice chunks and gets slower and slower, ao i stop and go drain the tank and put some oil in the tool and go another 10mins and repeat. I did stick a couple of engine heater magnets on it for 3-4 days with the drain opened and that helped quite a bit. Finally,i took about a shot glass worth of 91% isopropyl and dumped it in and thats been the best solution so far. Im tired 😂, i want something permanent like this (so i also saved the vid so whwn i finally get around ro it ill rewatch) Thanks man ! Edit: I just had a brain flatulation! I've got an old craftsman compressor with a dead compressor,I wonder if it's worth putting that in the unheated shop area and running the line to that instead of running off the line ? Maybe it would help some of the moisture issue as it's like a big separator and accumulator.

[@MrTheHillfolk]

2:25 those look pretty sweet. As I've recently installed an air ride in a car ,with the supplied separator it's a little tiny thing that fits in your hand, I need one of these to add in on that 😂

[@Bikerterje]

Great video! Just want to ask if it would be possible, or if you have considered, to connect all the downtubes and use only one drain valve?

[@BeckTools]

Thanks for the heads up! I'll look into this.

[@Leftseat1967]

I just bought a Speedaire 60 gal with a 5hp three phase 440 volt motor. In your video it looks like you're using a 3 phase converter to single phase? If so what is your energy usage with it? I priced the converter and opted for a new 220 volt single phase motor. In the long run would I still be better off with the original 3 phase 440 volt motor with a converter? My original 3 phase motor can be wired for "Low Voltage" of 230 volts, but I believe its still three phase not single phase. A 5hp converter is around $230-$250...

[@jeremymoore16]

To be honest. I would have put a silica gel filter on the compressor intake. Then on the high pressure side I would have installed 3x filter units rated to the max PSI of the high side. One filter would be filled with a particulate catching media and activated charcoal. The next filter would be silica gel beads then the last filter would be filled with zeolites aka molecular sieve. This is the exact set up I use for my plasma torch . In the winter get dew points in the air as low as -5 F, in the summer I see an average dew point between 13f and 25f, depending on the temp of the air. I also use a very similar setup for my pcp air rifle compressor. However the dryer for the pcp air rifles is much more expensive due to the need to have filters that can withstand 4000 psi without failing. With the above recommendations you would save space, time for not that much more cost wise especially if you count build time as money.

[@leegarcia81]

Nice set up but have you considered taking the air directly from the compressor outlet and running that through your copper system first and before it enters the tank. That eay you can avoid water build up in the tank itself. Also I see you have 4 valves. I would have hard piped those all into 1 valve that can drain all runs at once. And the added dead space where the t is can serve as a reservoir too. You can even add clear hoses to the parts were you have the valves at and make those all meet up into one purge valve. Then you could visually see the liquid as it builds up in each chamber

[@BeckTools]

yeah I made a follow-up video talking about these things. :)

[@AXNJXN1]

Smartly done! Love what you've done there!

[@jeffreymeyers7514]

Nice setup. I've got two 8 foot vertical runs of PVC. Valve 1 always has moisture. Valve 2 never has moisture that I can see but my system is for automotive which isn't as sensitive. Good for air tools and not pumping water into tires. Also use 45 angles to keep moisture off the wall.

[@ddemier]

What inline seprator do you use? I do Automotive refinishing as well and need to do some vertical columns like this but I'm considering 1" steel

Velocity approaches zero the closer you get to the surface (think of dust on your windshield).

[@jamescole3152]

I love it. Do you think the copper pipes will also trap any oil? Seems like it would.

[@BeckTools]

not sure

[@deakindog7525]

i've done similar for years on a bigger scale. what i see is your runs are 90 degrees off. you can collect water in each vertical. done horizontal with the pipes on a small angle one drain is needed. on my previous 2 shops i ran a wall of them (outside) then into another tank. i never needed to change the desiccant at my paint booth. at my current retirement shop i have a smaller wall (10'x8'), no additional tank and i get no water inside however i am not running the compressors as much when i had lots of employees

[@BeckTools]

I did just buy and electric auto drain valve for this system. I plan to connect all 4 drains to it and do some other modifications. That will be in part 3 of this series. I should have it in the next couple weeks.

[@peterchang7646]

Nice. My only comment is at about 5:50 of the video you talk about surface area of the 1" pipe as opposed to 1/4"... More air to copper contact on a smaller pipe than with a larger pipe... The ratio of air contact is higher - the smaller the pipe diameter is... That is why radiators, coolers tend to be made with smaller pipes than larger ones...

[@BeckTools]

yes they use smaller pipe but they than have to have 10x linear feet of said pipe. I want to save space, slow the velocity, and get lots of surface area at the same time.

[@simpsonrdlarry4385]

Looks like you put this video up in the dead of winter, not sure where you’re at but the humidity level is probably fairly low that time of year. How is it in the summer months?? Great idea and video just curious about humidity level

[@BeckTools]

Still working really well it was a winter time but I was cutting with a plasma table that has a water table so I get massive amounts of steam coming off the table that gets sucked in by my compressor

[@riftalope]

You can run vinyl tubing from the bottom of the valves to a single (ball) jar and see what amount of water you're keeping out of the lines. To affix the lines to a lid is tricky. I've seen hot glue on the outside of holes in the lid, and I've seen plumbing connectors inside the lid with larger holes. I prefer the later. But you must not screw the lid down firmly. You need that gap, and maybe a few nail holes, to let the air out.

[@BeckTools]

I would not use vinyl tubing.

I like it, do you know there are electric valves you can put on those drop legs that you wire into the compressor pressure switch? Then the system automatically purges water every time the air compressor cycles, then you don't have to drain the pipe or the air tank, they aren't expensive...

You could get an aftercooler to install on the back of the compressor and use the pump and motor wheel as fans to pull air through the aftercooler, the moisture will then condense into the bottom of the tank. Then drain the water weekly.

That would prolly work as well.
