You can get a gauge on ebay for $3.50. Shipping might take a while: www.ebay.com/itm/1-2inch-Dry-Utility-Vacuum-Pressure-Gauge-Steel-1-8inch-Center-Back-30HG-0PSI-AC-/252823059295?hash=item3add6dbb5f:g:Mo4AAOSw4GVYFxW9 Also, I have a few questions. 1. What's the highest vacuum you can achieve with a vacuum cleaner? And will this burn out the motor? Maybe you could use your gauge to test this. 2. What's the highest vacuum achievable with mouth-suction? 3. What is the relationship of air-pressure to R-value (thermal resistance)? In a perfect vacuum, heat transfer can only occur via radiation. But I'm wondering if you can determine whether the relationship between air-pressure and thermal resistance is linear, logarithmic, quadratic, etc. I can't find any data or a formula that relates the two.
Hey bud, I'm am A/C and refrigeration technician, first of all the compressor can go down to less than 500 microns or around 25 inhg. Secondly those compressors require oil in the Freon flow and Freon flow to lubricate and cool the compressor. running it the way you are is not very reliable and is going to have very short life.
MrJaylassiter you could have the input line have a oil/lube drip/mister so the air it's pulling in has some lube but unless you can recover that oil in a catch pan for later reuse. you will end up just wasting the lube.
meh, somewhat, you would have to get an inline oiler that's for like an air compressor and put on on the suction side with the correct oil for that compressor( depending on what Freon it took depends in the oil it needs) as for the cooling no, no way to work that since it is the actually cold Freon gas that cools the compressor.
themeez1000 for smaller vacuum setups, I wouldn't think heat would be that big of a deal. compressors can handle such huge temp delta from in to out that a short run of like 10min or so (lubricated!) wouldn't do much damage at all *my opinion, not fully sure
A search on how to convert a fridge showed me this video. The level of detail, and the demonstrated level of competency at working with tubing were my first clue that this wasn't going to be useful to me. And to top it off, at the end our guide says that (despite showing one in the thumbnail) he doesn't have a vacuum gauge, but he's ordered one that should arrive "soon", with the promise that he'll put the measured results in the description. But here it is _6 years later_ and there's nothing to tell us how successful he was - or wasn't. Shows how much he cares...
To help with the soldering (I used to work in HVAC). Clean the end of the tube then apply some flux to the end of the tube. You have to use MAPP gas because propane wont burn hot enough. The solder should melt when it touches the copper pipe and be drawn into the heat. Solder like to move towards the heat. Hope this helps, fun videos as always
Not sure if you were making due with what you had on hand (because I've done the same thing in a pinch) or if you didn't know, but the fitting that you pressed into the hose @4:27 is the male end of air line quick connector and not a barb that would be use in this case. Oh and the "check valve" you used is just a 1/4 turn on/off ball valve. I'm sure someone else already told you, but I just wanted to let you know. Hope you get to feeling better! keep up the great work!
I always wonder why you only have like 108k subs. Your videos are very professional and you have a great style and very cool ideas. Keep the good vids coming!
It was still a good video. :) hope your well. (This should make you feel better if not) I learned something new the other day. I learned how to make a very cheep electric fence. (The hard way) lol.All you need is Christmas lights. Yep, almost may and I still have Christmas lights up. .. anyways... I went to take them down while they were still plugged in. They went across my chain link fence. Well, it was a little wet outside and I didn't notice at the time that one (possibly more) of the light bulbs were busted. So when I touched the fence I became the light bulb and since it was wet outside, it took a few seconds for me to release my grip on them. Yep, that beats any coffee I have ever had in the morning to wake me up. I am ok. So that is how you can have a electric fence for cheep. But I am curious to see how much my pg&e bill would be if I did leave something like that on. Would it constantly draw large amounts? Take care. Hope you enjoyed my "bright" idea. Ha
You can do this with a normal air compressor as well. The one I used can easily vacuum down to boil off water. You can also use the refrigerator pumps as an air compressor in a pinch but the normal fridge ones are very low volume (slow) The other trouble with the refrigerator pumps is they easily overheat, and eventually sieze for the lack of oil even when the heat issue is avoided by only using it with short on cycles. These are so low volume that any vac forming has to be very small indeed.
However that said, yes I have played with these and they were instrumental in many of my childhood experiments. Went through a few of them (uncle was an HVAC guy) These are great for MANY experiments. Good vid, please keep them coming.
Are you using this to make your own components like Tesla? when he used shellacs or resins to seperate parts he would first vacuum to get out most air then allow part to dry under high pressure compressing any small air pockets that might have remained.
Electrical excitation of oxygen molecules in the upper atmosphere from lightning aids in the formation of ozone, many people (not you!) still think that it cannot be rejuvenated.
I used to build custom refrigeration systems, so I have experience at this. Soldering copper tubing generally needs acid flux and preferably, silver solder, working on clean metal. When sanding the stubs of tubing, turn the unit on its side if necessary, more than 90-degree turn even, so the grit will not go down the tubing into the compressor. Or plug the tubing with a rolled up bit of paper towel, to be removed after sanding. Just be careful not to dislodge the temporary plugs while sanding! _For better vacuum, especially for deep vacuum, pump _*_into_*_ vacuum!_ (Deep vacuum is always good, but especially needed for vacuum tubes.) For instance: Run 2 old compressors in series, with the outlet of one into the inlet of the other. If one has larger capacity than the other, you would generally want to put it on the low-pressure side, for maximum pumping rate, but valving varies and some valves require more pressure to open than others. The one with least valve restriction at low pressure should be the one connected to the system being pumped down. Also, a proper vacuum pump can be boosted with a crap pump like a single old compressor, IF the proper pump has a vacuum fitting on the outlet. Another way to go is to pre-evacuate a large cylinder and attach it to your pump outlet after it has pumped what it can out to atmosphere. You also can increase pumping speed --and protect your pump from water damage-- by using a makeshift cryopump; that is, pumping through a U-shaped section of larger tubing you have prepared for the purpose of dunking in ice water with salt poured over the ice. Salt over ice makes the briny solution temperature drop to near zero Fahrenheit, so it can condense some water vapor even in vacuum. Better still, submerge the makeshift cryopump in a container of dry ice and alcohol, or if you can get it, use LN2 (liquid nitrogen). Copper wool (or brass wool or stainless-steel wool) inside your makeshift cryopump will improve the performance by adding a large surface area on which the pumped molecules can slow, contract, and even solidify. Purging the whole system with *very dry CO2* will allow you to turn a crude vacuum into a high vacuum if the cryopump is chilled with LN2, because the CO2 will solidify on contact with such low-temperature surfaces. Other gas molecules being carried along by the CO2 will get buried and trapped in the dry ice formed in the LN2-cooled cryopump. Normal refrigerants will also solidify in a LN2-cooled cryopump. With proper valves installed and operated, you can make a laboratory-grade vacuum in a cheap way. After using the cryopump, be sure to warm it up and pump it out with your regular pump, to dry it thoroughly. As always, higher temperatures of the system being pumped will speed the process of evacuation. Water is particularly sensitive to temperature and will basically not pump at all near 32 F (0 C) unless the vacuum is prolonged and very deep.
you should try making a weak fusion reactor, not just a fusor. I made a tiny one using a vacuum pump and old high vacuum parts from ebay and scrap yards and ta refrigerator pump. if you need deuterium praxair sells it, you just need your own canister.
have you seen codyslab before he made an old fassion mercury powered vacumme pump its an interesting video I wonder how much of a vacume it creates because its almost perfect if not a perfect vacumme
+josh greg yeah! He is probably my favorite person on RUclips! And yeah, I think using that process you could get a very good vacuum although I am also not sure of the physics to calculate it out
Add a pressure chamber then you get a higher vacuum than just the pump itself, since those compressors have really small displacement but are instead extremely high powered for their size, actually add two chambers then you have both vacuum and compressed air from one unit. Old fire extinguishers should work.
I sware... I must be the only poor bastard in the entire world trying to do this with a compressor that has 4... YES FOUR FRICKEN PIPES! (5 if you count the freon pipe.) This is not helping my covid depression at all > SMH.
Where the fuck did my other comment go? Anyways add a pressure chamber like an old fire extinguisher or diving tank and you'll be able to pull a better vacuum, add another and you get compressed air aswell from the same unit. The compressor is strong as hell but it's displacement is minimal. Also if you haven't make sure to change the oil since it's made for freon not oxygen/air, it can ignite if worst comes to worst. All of this probably occurred to you already keep up the good work 👍
+Elektro Bear I'm not sure where your last comment went, I had thought a bit about adding a pressure chamber but I do think you are right and I will defiantly try it out! Thank you! :D
Man, I understand, but u speak much fast, please speak slowly hahaha some people are of country that the English is not the official language, and is not too easy to understand, just a tip 😉 Your video and explanation is very good.
I definitely want to see you create an x-ray imager... but, the number of other people across the country doing the same without proper shielding but a cheap building wall or shed makes me nervous. Also, cancer is a bitch.
No offence, but your voice sounds a bit annoying. Maybe it's the pace or maybe there's sth I don't like about your audio recording. Anyway, good job there!
The reason you suck at soldering is your lack of steel wool. You have to clean the copper and use lots of flux. Get yourself a flaring tool and you can flare the copper to fit tightly in the other pipe.
I once made a refrigerator out of a fridge compressor and I traded it for a key. They key opened a box on a boat at a local marina but to get to the box I had to buy the boat. At the time I thought I'd never get to see what was in the box, but one night on my way home from yoga class, I started thinking about gasses and things and how my mortgage wouldn't be paid out until it was paid off and as I trudged along towards an oncoming stampede of antelope, my downward gaze caught a sparkle that could be only one thing...a girl's best friend. The one that is forever. The diamond. As the herd barrelled toward me I curled up into the smallest form I could physically achieve, and as the beasts bore down upon me, I snatched the stone with my three-fingered hand and swallowed it dry. Now I'm's after having a difficult poop and a long canal ride to be meeting with my confidant Chum Lee, an international jewel dealer, and he knows a Scot living in Uganda who would give me enough to buy the boat. Soon I would have $3000 and the wonders of the box would be mine. I still don't know how to get the last of the butane out of my live resin, but the box may hold the secret...
IIRC not a piston type pump, but one with a spiral drive(hard to image I know) - google scroll pump/compressor. Otherwise your fridge would be way louder.
If you want to learn how to solder, first, clean everything with emery cloth and then use flux. I have a frig compressor vacuum pump and they work VERY well. You'll be surprised.
hey bud......cool....... I'm pretty sure that those type of compressors have an oil solution mixed with the refrigerant gas for lubrication & cooling........not that it definitely wont function at all running it dry(perhaps at least for short periods of time)..........but it will most certainly VASTLY reduce its lifespan.
LMAO HAHAHAHAHAHAHAHA too much ChaChaCha the first 2 minutes but informative, glimps of a genius mind. You're Smart, but Hands On LOL you get an A+ for effort. l liked that you thought outside the box and still got it to work. Thumbs UP, good video. i Like, OLE!
I work on submarines and we had a significant slow leak on our a.c. unit on one underway. we had to keep going. after a week my body started aching and I got terrible migraines.
are you sure? that looks like a scroll compressor. also... what are you using as coolant/lube? those compressors usually require the refrigerant to be in the compressor as a lubricant. or the compressor will die much much quicker.
this video wasn't boring it was awesome dude I had a broken frige we were going to toss away I didnt know it was useful until now. I could make a vacume pump and one question were is the Freon? i want to dispose of it properly
three wheela i know were it is i ment to say were to dispose of it? Can i put it in a bag an burry it ? Can i use it for anouther project? Can i create ozone and let the freon bind with it? I dont know what to do with it
Lord Awesome unless u have a machine to recover refrigerant then there is probably no proper way for u to get rid of it or use it for some other purpose unless it is a flammable kind
In regards to soldering the pipe... score and clean it first with a steel whool or steel bristle brush, then apply flux and heat just below the flux until you see it start to form a droplet and then run your solder across it in streaks covering the exposed surface. After that use the steel whool or steel brush again 👍🏻 then fit into the receiving fitting and heat and rotate until sealed and apply additional solder as needed 👍🏻
Nice video thanks , 👍 one of the guys made interesting comment that these usually have freeon gas in them which has oil lubrication in it for the compressor .. so surly running it dry will damage it ??
Great job on the video. Like your refrigeration diagram, however It is important to note that the vapor compression refrigeration cycle doesn't work with just a pressure change but a phase change with the refrigerant. There is a solid column of liquid always feeding the expansion device on the high pressure side which flashes to a vapor on the low pressure side. It is the condensing of the high pressure high temperature gas on the high side (Condenser - Hot Side) which releases heat absorbed by evaporation of the liquid to a gas on the low pressure side (Evaporator - cold side). Older CFC (chlorofluorocarbon) R12 "Freon" systems most commonly used mineral oil or a synthetic oil called alkyl-benzene (AB) for lubrication and are very benign. Newer HFC (hydrofluorocarbon) R134a systems use POE or PAG oils that are extremely hygroscopic (absorbs water from air) and turns to acid which attacks all components including the varnish on motor windings. If you were to attempt this you definitely want a compressor which has mineral oil or alkyl-benzene (AB) for lubrication. As mentioned by others refrigerant is used to cool the compressor motor windings and that heat is usually expelled by the condenser. Oil also mixes with the refrigerant and is carried around the refrigeration loop back to the compressor. Some compressors do have internal lubrication strategies and don't rely on refrigerant flowing in the system, but without the flow of cool vapor refrigerant back to the compressor, the windings will continue to heat up. If you do this for a quiet air compressor or vacuum pump, then keeping the load minimal and operation time short is critical for the lifespan of the compressor. The thermal cutout (unless internal in the windings) is external to the compressor housing and relies on refrigerant in the compressor shell to properly sense the temperature of the windings and shuts down the compressor if it overheats.
How would this pump handle liquids intake? I'm looking for a DIY vacuum for when I want to separate solvents under a vacuum condition. But this will cause solvents to enter the vacuum system.
Nice Video, but I have to mention that I can tell you how much pressure the tube must withstand. The maximum possible is your local atmospheric pressure.
A video on how to make an inverter plz. I'm looking to use the induction heater powered by a car battery and need to step up the voltage in AC then covert back to dc
Ok, by the way, I made a miniature Tesla coil using a boost converter, I realized the circuitry for a Tesla coil was basically a rapidly discharging capacitor, and a boost converter was a rapidly discharging capacitor, so I figured, all it was missing was the coils on the output, and with a 1/4" spark gap tada, It matches the frequency and voltage of the spark gap, lit lights up florescent bulbs, and the secondary coil glows, but it's so low current, It can only be seen in the dark.
You are very welcome. Keep going with your videos they are great. I remember when Bill Nye started off on a Canadian comedy show called SCTV . Your science is very concise and easy to understand. Keep up the good work
You're a cool dude. You know that? You remind me a lot of my younger brother. I started him off with electronics and computers but he was the one to follow it into an computer engineering degree. I couldn't keep up with the tech and my hands just became too unsteady for such work. Long story short: Good stuff, man. Keep up the good work.
I find your channel entertaining! Good job on keeping me around months now! i'm still waiting for your version of the laser razor. also thank you for doing these videos
genial esos compresores son muy buenos hacen un buen vació pero también tienen bastante presión ese compresor debe ser como de un 1/3 hp yo solo tengo uno pero de un 1/6hp muy ben vídeo amigo
+PASSTRAN Sí que son buenos, sin embargo, creo que sólo debe correr por un máximo de alrededor de 30 min porque tey sobrecalentamiento cuando se utiliza esta forma ive encontrado. También muchas gracias!
This weeks video is going to come out a bit late, sorry guys!

It won't last very long. However this also works for building a silent compressor for using air tools.
So three years later I wonder what Vacuum it pulled ?
it was meant to be in the comments as said...............
After emptying the oil, what kind of oil do we refill it?
you are SO awesome! Yeah I'm sending you mail, I might even send a few of my favorite electronic components too! :)
It's on its way!
Great video, thanks! I need compressors for the vacuum system of my proton accelerator.
Looool me too!
my mom is happy because i decided to do mechatronics :)
Hahaha!
So howmuch of a vaccuum does it pull? I dont see the description where you added it?
hey fun fact, you might be able to use that compressor to make a liquid nitrogen generator
Still waiting for USB killer video :3

plastic tube instead of welding was a good trick. thanks.
IIRC not a piston type pump, but one with a spiral drive(hard to image I know) - google scroll pump/compressor. Otherwise your fridge would be way louder.
5:34 what's its vacuum capacity in mm of mercury ???? Is it capable to create high enough vacuum for x ray tube ( 10^6 mm hg ) ??
hi best youtuber

how to make a fridge out of a vacuum pump
If you want to learn how to solder, first, clean everything with emery cloth and then use flux. I have a frig compressor vacuum pump and they work VERY well. You'll be surprised.
hey bud......cool....... I'm pretty sure that those type of compressors have an oil solution mixed with the refrigerant gas for lubrication & cooling........not that it definitely wont function at all running it dry(perhaps at least for short periods of time)..........but it will most certainly VASTLY reduce its lifespan.
what is almoutous law, is it gay lussac law what you mean?
LMAO HAHAHAHAHAHAHAHA too much ChaChaCha the first 2 minutes but informative, glimps of a genius mind. You're Smart, but Hands On LOL you get an A+ for effort. l liked that you thought outside the box and still got it to work. Thumbs UP, good video. i Like, OLE!
I work on submarines and we had a significant slow leak on our a.c. unit on one underway. we had to keep going. after a week my body started aching and I got terrible migraines.
I have an advice the best way you can use this compressor is for pumping not vacuum it's so weak for sucking and it can reach 20 bar i guess
Hi ;) Do you have any idea about making a tesla coil using socket electricity? Its 230V so ot could be really cool...
That was about the most absolutely confusing description of how refrigerator works I have ever seen.
the compressor is going to be destroyed if you run it without oil or an air filter.
+Corbett Sonoda yeah, it already had oil in it, but a filter would probably be good to add
So.... how much of a vacuum can it pull? I don't see anything in the video description.
About 2 years ago I had a fridge compressor blow up in my kitchen. Not even an old fridge but of course out of warranty. RIP ozone :(
That's how terriosts will take over, by leaking Freon into the atmosphere
are you sure? that looks like a scroll compressor.
also... what are you using as coolant/lube? those compressors usually require the refrigerant to be in the compressor as a lubricant. or the compressor will die much much quicker.
this video wasn't boring it was awesome dude I had a broken frige we were going to toss away I didnt know it was useful until now. I could make a vacume pump and one question were is the Freon? i want to dispose of it properly
Lord Awesome if you don't know where the refrigerant is then u definitely have no business trying to make this project
three wheela i know were it is i ment to say were to dispose of it? Can i put it in a bag an burry it ? Can i use it for anouther project? Can i create ozone and let the freon bind with it? I dont know what to do with it
Lord Awesome unless u have a machine to recover refrigerant then there is probably no proper way for u to get rid of it or use it for some other purpose unless it is a flammable kind
Can you make something that can fill painball air tanks? needs to pump up to 2000psi :D
Notification squad!
Freon is a brand name
In regards to soldering the pipe... score and clean it first with a steel whool or steel bristle brush, then apply flux and heat just below the flux until you see it start to form a droplet and then run your solder across it in streaks covering the exposed surface. After that use the steel whool or steel brush again 👍🏻 then fit into the receiving fitting and heat and rotate until sealed and apply additional solder as needed 👍🏻
why every video is "be carefuller to not create a global catastrophe" the microwave gun than this
What are you doing with it?????????
Nice video thanks , 👍 one of the guys made interesting comment that these usually have freeon gas in them which has oil lubrication in it for the compressor .. so surly running it dry will damage it ??
So how low is the vacuum?
Great job on the video. Like your refrigeration diagram, however It is important to note that the vapor compression refrigeration cycle doesn't work with just a pressure change but a phase change with the refrigerant. There is a solid column of liquid always feeding the expansion device on the high pressure side which flashes to a vapor on the low pressure side. It is the condensing of the high pressure high temperature gas on the high side (Condenser - Hot Side) which releases heat absorbed by evaporation of the liquid to a gas on the low pressure side (Evaporator - cold side). Older CFC (chlorofluorocarbon) R12 "Freon" systems most commonly used mineral oil or a synthetic oil called alkyl-benzene (AB) for lubrication and are very benign. Newer HFC (hydrofluorocarbon) R134a systems use POE or PAG oils that are extremely hygroscopic (absorbs water from air) and turns to acid which attacks all components including the varnish on motor windings. If you were to attempt this you definitely want a compressor which has mineral oil or alkyl-benzene (AB) for lubrication. As mentioned by others refrigerant is used to cool the compressor motor windings and that heat is usually expelled by the condenser. Oil also mixes with the refrigerant and is carried around the refrigeration loop back to the compressor. Some compressors do have internal lubrication strategies and don't rely on refrigerant flowing in the system, but without the flow of cool vapor refrigerant back to the compressor, the windings will continue to heat up. If you do this for a quiet air compressor or vacuum pump, then keeping the load minimal and operation time short is critical for the lifespan of the compressor. The thermal cutout (unless internal in the windings) is external to the compressor housing and relies on refrigerant in the compressor shell to properly sense the temperature of the windings and shuts down the compressor if it overheats.
How would this pump handle liquids intake? I'm looking for a DIY vacuum for when I want to separate solvents under a vacuum condition. But this will cause solvents to enter the vacuum system.
Don't have an answer for you but in a way of pointing you in the right direction, look up scroll compressor
Тема интересная Я тоже сейчас делаю. Использовал трубки для фильтра от воды
(0:23) - It's "Amonton's Law", not "Admonton's Law". That ruined it for me.
Try a ballpark of 25 bar.
now that I have a new phone I can watch your mediocre videos in glorious 1080p. jk I love ya
Nice Video, but I have to mention that I can tell you how much pressure the tube must withstand. The maximum possible is your local atmospheric pressure.
So how much of a vacuum did it pull? You promised to post that!
A video on how to make an inverter plz. I'm looking to use the induction heater powered by a car battery and need to step up the voltage in AC then covert back to dc
Really nice, man. :) Try making a vacuum forming machine. ;)
Are you going to show us those Tesla coils in the background in action?
+Dobby Yoda haha I'm sorry dobby, I know I have been giving you the same answer for a while, but I hope to soon!
Ok, by the way, I made a miniature Tesla coil using a boost converter, I realized the circuitry for a Tesla coil was basically a rapidly discharging capacitor, and a boost converter was a rapidly discharging capacitor, so I figured, all it was missing was the coils on the output, and with a 1/4" spark gap tada, It matches the frequency and voltage of the spark gap, lit lights up florescent bulbs, and the secondary coil glows, but it's so low current, It can only be seen in the dark.
I love your videos .
I hope you feel better soon.
copper and zinc works great for colds. as well as colloidal silver.
get better buddy .
+Mark Giza thank you!
You are very welcome.
Keep going with your videos they are great.
I remember when Bill Nye started off on a Canadian comedy show called SCTV .
Your science is very concise and easy to understand.
Keep up the good work
this kind of sucks 😅
You're a cool dude. You know that? You remind me a lot of my younger brother. I started him off with electronics and computers but he was the one to follow it into an computer engineering degree. I couldn't keep up with the tech and my hands just became too unsteady for such work.
Long story short:
Good stuff, man. Keep up the good work.
musical ZVS circuit please it would be awesome if you did
Please show the component name in your video, thank you.... from indonesian brother
Hi, can you do one video about how remote control drones operate & how the circuit works?
make a video about xray pls
AWESOME projects on the way. Don't forget youre amazing
+Sergio_ montevideo haha thanks! You are too!
super
Can you make an tutorial how to build that big Tesla Coil in the Background?
can you make a video on why it works to make hydrogen from salt water?
Yes, Freons (Kohlenwasserstoffe) kill the Ozone.
Nice Project
you never posted how much vacuum it can pull.
I find your channel entertaining! Good job on keeping me around months now! i'm still waiting for your version of the laser razor. also thank you for doing these videos
This sucks
you ought to put a fitting on the output as well so you can use it as an air compressor too
genial esos compresores son muy buenos hacen un buen vació pero también tienen bastante presión ese compresor debe ser como de un 1/3 hp yo solo tengo uno pero de un 1/6hp muy ben vídeo amigo
+PASSTRAN Sí que son buenos, sin embargo, creo que sólo debe correr por un máximo de alrededor de 30 min porque tey sobrecalentamiento cuando se utiliza esta forma ive encontrado. También muchas gracias!
heys
