A tip for diyers. Old fridges and freezers make great boxes to store paints in. They keep them from freezing in the winter. Obviously you dont plug them in or turn them on. But when you gut one like this or have a dead or old one dont chunk it.
They seal so make a good storage place for oil cans ect
Great tips thanks, btw i live in tropical country
I built one of these about a year ago, I put a foam paint roller pad, the 5" size i cut them to 3" and they fit perfect, on the tubes that draws in the air to keep any dirt out of the compressor body. I would recommend covering the fan blade so no one gets hurt.
Kindly tell me does this work well and is durable enough to last at least 3 years with out coil of compressor spoling
@@kirabirarobert1920 It depends on the condition of what you start with, what you use it for, how long it is running per day.
11:50 колеса - спорное решение. во-первых: очень широко. оно конечно устойчиво будет, но с другой стороны не везде по гаражу протиснешься с такой телегой. имхо, надо было разогнуть эти S образные ножки - сделать вертикальные стойки. заодно - между ними под балоном прокинуть пруток, чтобы их от веса в разные стороны не разогнуло... в остальном респект ваще за руки и за смекалку. обожаю глядеть как люди работают головой и руками. спасибо!
Super wykonanie ✌️😎pozdrawiam
You forgot to add water discharge under need and air filter both pumps and between 2 pumps return valve. But great work!
Хорошая штука получилась. Обязательно сделаю, буду газон продувать. Супер.
My only critique is that you need to have the tank pressure tested to at LEAST 20% higher psi than you will have the cut off set as. The tank was originally designed for far higher pressures, but you don't know how pitted the inside is from moisture, so the testing is at least a good idea.
👍😉
Hi you say this tank he's using was designed for much higher pressures do you know how much? And do you know how heavy it is? And when full of gas how heavy then?
@Dragomir Ronilac somebody has to be the first to try things to embark on newer knowledge. I'm just looking for a work around if I can find one
@ Don Natalie Lucas, I’ve been watching some compressed air videos, there’s a surprising lack of knowledge not only around good practice but more worryingly the devastating effects of compressed air when it goes wrong. From using propane tanks, to tyre inflation one guy is aiming for 300psi.
Just hope people who are unsure what they’re doing just buy an off the shelf compressor.
@@hitop2365 I personally witnessed the aftermath of an air tank explosion over 35 years ago. Everyone was fortunate to have not been there when it happened because the amount of devastation would have easily killed us. It was also good that a vehicle wasn't in the shop because the damage would have cost thousands of dollars to repair. A portable air compressor (I think it was a 30 gallon tank) that was rated to operate at 150psi had a sticking shut off switch that wouldn't shut off until around 175psi. It also was an older unit that had been placed under the corner of a farm shop bench made of rough cut 2x8 wood. It had not been pulled to be drained regularly & would only get drained when there was a significant amount of water coming out of the hose. We would unplug it when not in use, so the nobody worried about changing the cut off valve immediately. It was slated to the "next trip to town" status. One night we had forgotten to unplug it after working in the shop. About midnight there was an explosion loud & violent enough to be felt in the house about 100 yards away. When we got t the shop, there was a corner of the concrete block building blown out about from ground level to the 4-5 foot high mark & around 10 feet down the wall. Pieces of the boards from the bench were strewn about as well as parts of the 3 layers of 2" thick wood from the edge of the sliding door. Inside there were parts of the air tank blown into the ceiling, the door, the opposite side wall 30" away, & into the 14ga toolbox in the opposite side corner. Looking at the parts showed that the tank was pitted in the lower 1/4 level. We knew the cut oof device was defective but had not even thought about the safety pop off, which was found & was stuck shut. The motor was located nearly halfway to the house & the compressor unit was obliterated. We learned several valuable lessons that day. The best were that the tank MUST be drained EVERY day, to periodically check the pop off, & replace the cut off device IMMEDIATELY when it is defective.
So great idea but whats lubricating the values inside without refridgerant?
Very cool, but I don't think you need the fan. 😎😂
Nice build , maybe make shroud to cover fan ,from prying fingers. Oh also the air inlets. Maybe a filter box for unwanted blockages !
Fan not required. 🙂
Guy builds a compressor that works and people are telling him how to turn a screw.
I like it It would be neat to know whether you can run things like a Dynabrade sander or an impact tire lug wrench.
2 things :) First: you won't cool the compressors with that fan :) the compressors are cooled with the intake of air / gas, second if you don't discharge the compressor lines with the regulator you'll have a bad start and the compressors will switch off termically close one of the inlets of the tank and the compressors air out should be connected to the regulator also
Some fridge compressors have oil coolers
those fan expose also not safety at all, should at least make a cover
Nah mate, you're wrong about the cooling part. The air that gets compressed releases a lot of heat into the compressors. The fan is useful for cooling them down. In a fridge there's usually a plastic cover on top of the compressor. That's where the water that condenses in the fridge runs off to. When the water heats up from sitting on top of the hot compressor is evaporates and cools the compressor.
So the fan is actually a very good idea.
These compressors are designed so that the stator is cooled by the refrigerant returning from the evaporator. The fan is to cool the exchanger or condenser, helping the thermodynamic cooling cycle. So it doesn't really help much to cool the compressor motor.
Very Good Job ! Congratulation ;o)
wonder i had mad one like that, from LPG gas tank,BUT first i removed all nuts and taps, then i cleaned inwards, to remove rust, then i filled it with EPOXY paint for rust protection, and then WALLA loll, wish u did that so the tank will last more then your life, ,great work mate
Nice build my only suggestion would be to add a intake filter from an gas powered remote controlled race car. They fit right on
Thanks !
Good job you have thumbs up, but I don't think you need the fan at all.
Thanks bro thanks for nice comment and your idea💡👍
How do the compressors stay lubricated since the oil that lubricates them is normally in the freon that flows through them?
True, the oil was supposed to be drained, and replaced. I think the oil it uses Is polyester oil
Polyester Oil (POE oil) is a type of synthetic oil developed especially for refrigeration compressors.
The compressors will fail after about a year or two from lack of lubrication because of what you said. Since the oil in the compressor is very little, it wont do any good as an air compressor. I know it happened to me.
Obavezno dodaj kakve filtere na usis zraka, ništa specijalno samo da zaustavi prašinu. Bilo bi poželjno imat i sigurnosni ventil, ako presostat zakaže ode sve u zrak. Najveći problem je zapravo šta ti kompresori imaju ulje koje cirkulira zajedno sa rashladnim plinom, a sad kad je sustav otvoren to ulje će kadtad nestat i kompresori će zaribat. Inaće odličan projekt za početnike, samo tako nastavi :)
Hvala na komentar
Well, it looks professional! Good Job.
Thanks my BRO 👍😊
as you said it looks like a professional but it doesn't come close to that, it's very amateurish, let's buy the parkside better than the lidl
Great job!
👍👍
Wow you r best
Thanks a lot 👍😉
I hope your poor daughter wasn't too upset daddy stole her stabilisers? .. so I have one of these compressors, I was handed a compressor and a large old gas tank. I had visions of combining, similar to you. My question is, the compressors you used, how and when would you add/need to add oil to them? The compressor I was given is half the size of the bottle you used but the LPG tank is about 5 foot tall. Could you in theory have 5 or 10 of these fridge compressors all working together.. in theory. But what about oil etc?
Sangat rapih sekali mr...
Very good Idear thank you share.
Most welcome 😊
If I had a dollar for every thumbs up shown in this video I could pay this guy to build me one of these compressors.
Respect Doamne ajuta un mare Laik
YEAH COULDN'T HEAR A THING! REALLY SILENT. EXCEPT, HOW DID YOU GET IT TO PLAY THAT MUSIC?
I like how you made the air compressor ok but what's the fan for 🤔 I don't see it doesn't do anything for it
You shall add safety cover for fan, and air filter for air intake. I hope if you can measure noise or show compressor voice, thanks. Also I think you can improve control to run only one compressor if no high demand
Thanks for the tips!
Great job. Well done.
Thank you!
Complimenti da carmine da eboli (sa),molto interessante sei molto bravo.
It is very well done but you should put a protector on the fan
nice 1 bro i was planning to make like this when i got home to philippines. from now im in japan i cant go home because of this pandemic shit... God Bless bro thanks 😊
good job
Thanks a lot bro 👍👍
When you get any tank that was used for air .... Inside it there might be a lot of rust.... Fill it up with white vinegar to help it soften all the inside rust then after two three days being filled with vinegar put a rag inside it after you have emptied it and shake it around inside there so that the rag can rub off all that rust inside it you can put a cup of water to help the rag become heavier and you'll see how clean it is inside, do that only with a rag two three times that way in the future the tank will not explode because of the rust eating through the inside of it

Bravo majstore
👍👍
I would have kept the condensor and turned it into a dryer/cooler. Lots of water going into that tank otherwise. Given the very high pressure these things are capable of, a small HP intermediate tank and regulator would allow you to have super dry air going into the main tank
Would you know of a video explaining what you just said?
Amazing Homemade Video Project 👍😉
Thanks BALKAN Mr DK DIY
Sart
Does it take 9 minutes and 45 seconds to reach 8 bars? but that is a lot, it would not do to paint, because when you are painting the compressor stays on
Good DIY video, I found it fairly easy to follow.
It looks like you used 10mm? pipe would there be an advantage in using 15mm?
Thinking it would speed the process up and give max pressure on delivery?
👍👍👍👍👍 All signed up😂
Might be an idea to put a guard on the fan especially as the blade is metal.
Great vid!
I did this as a kid to power airbrush. Thing to watch is the compressors spit their lube oil out with the air. In a fridge its a loop so never gos dry. Your oil will be in tge tank with water with no way to libe the compressors. You can see them spit oil on your finger pressure trst. Good effort tho
îs very important, you need security valve.
Engineer here, really cool video! The compressors do not need a fan to cool them btw. Their temperatures were regulated by the oil in the R-12 refrigerant when they were used in the fridges. I would remove the fan because it's a hazard - someone could get their finger cut off! Also, what did you do with the R-12 refrigerant gas when you took the refrigerators apart?
👍
You didn't see tube was cut and it went into the atmosphere lol
How long do you expect it to last? The reason I ask is. the freon has a lubricant in it to lube the compressor .
We need review to se if if it will last.
Simple..... you put 10-40 oil in the air intake problem fixed kinda how you put oil in your air tools before you use them
@@sibosifraiscompagny , naaah. It won't. You need to add compressor oil very often. Otherwise you burn the compressor. Your system is open bro!
It’s easy enough to replace the oil with clean mineral oil and that will suffice however the moisture accumulation is still an issue however that can be solved by replacing the oil depending on the frequency of use. If output moisture is a concern regarding your air tools or for painting applications, you’d simply run the output from the compressor into a small radiator fan and then an auto draining moisture trap and lastly plumb it into the tanks. This will result in roughly 85-90% +\-less moisture in output air entering the air tank.
my dad has used a compressor like that for years with no extra lub or filters.
These comressors are filled with oil from the factory, they are ment for a closed cirquit and oil can not be changed. Hence it is of great importance that you have filters on the air intake othrevice the oil will be contaminated soon.
Not to mention, the refrigerant carries the mineral oil through the whole system constantly, so I wonder if the intake side of those compressors are even getting any oil. Maybe run a drip oiler inline with some mineral oil.
Very good ideas, but what's the use of the fan? It is dangerous unguarded. It needs a safety valve as well as an additional protection if the pressure switch fails to cut out and there will be less risk to burst the tank. G. Cutajar. Malta.
Thanks for Nice comment
@@MrDKDIY You're nicer to me, I'd told him to keep his bike helmet on and stay safe. We live in a weakling world today.
👍😉
You should weld your init.s on the side of the wd 40
...very inspiring...
Thumbs up!!
Thanks bro for this great comment
Connecting the motors in series (the air output of one to the input of the other) might be a better idea. And/or a one way valve. That way, one motor helps the other to overcome the growing pressure on the tank faster
Running in parallel is a better option as they dont have a huge output. These compressors can exceed 850psi so overcoming pressure isnt an issue. At best this pair of compressors will deliver 1.8cfm so it will take a while to fill the tank. I didnt see an unloader in the video which is very bad news for the valves in the compressors.
@@atomizer2665 I get what you mean and parallel or series may not be a huge difference when blowing air, but for a vacuum pump you get a little extra vacuum if you connect them in series. I've seen that configuration, same compressors connected in parallel and then in series. In parallel you reach around 80mBar of vacuum. In series you go down to 40mBar which, for things like silicon molding and resin casting, can make a huge difference
@@tricky2k
You need them in parallel for air compressor purposes, it will double the output cfm. For vacuum, sacrificing half of the flow rate using the 2 stage (series) arrangement is no biggy.
The volume of the first stage has to be higher than that of the second
@@atomizer2665 Unloader couldn't be installed cuz ther's no god damn check valve
always put wire on opposite side of screwing direction... thus your ground wire should have been on bottom so when you tighten, it will pull the wire into the clockwise direction of screw.. if you put on opposite side it will push wire out instead of pulling in. not a bad idea... these fridge compressors pump very high pressures too, just not much volume (r134a are capable of somewhere upwards of 600-800 psi)
I need 3600 psi. Any suggestions?
Good work..but no need of fan 🤷♂️
What about oil inside the two compressors housing? When empty, compressors will dead. Need a oil inlet for both them.
Perfect ❤❤❤💪💪
Thanks
Motor can be different powers or must have the same nominals?
can you answer me please?
Why is the fan facing away ? It's not like it's closed in . Don't get it ? Anyway nice job...
good work
Молодец!!! 👍👍👍👍👍

Nice idea but I'm wondering how long the compressors will last pumping only air without any oil that was in the refrigerant?
Fridge compressors have oil in the bottom and it comes out in a mist with the discharge air. In this setup he will have to add more oil to the compressors and drain it out of the air receiver on a regular basis. I built one of these years ago, and I added an oil separator to the compressor discharge pipe. When the separator bowl got full I just poured the contents back into the intake pipe, and that seemed to work fine. I also added a sight glass to the compressor tank so I could see if it got low.
A fridge compressor has oil in it, a wet sump system, it does not rely on the refrigerant. If you turn one upside down all the oil runs out.
@@connerlabs these two items can they be asked for at home depot? Oil separator and sight glass.
@@aicram62 I’m not in the US so can’t comment on Home Depot. Any place that sells compressed air equipment should have the oil separator. I made the sight glass myself with a piece of clear plastic tubing, 2 90 degree hose barbs, and 2 holes drilled very carefully in the compressor.
Bro which port did you connect the fan cable to?
Lite vacuum? Thanks a lot
Great work, my friend, but allow me to ask what is the capacity of the refrigerator motor, and is a fire extinguisher with a capacity of approximately 8 liters, with a refrigerator motor of six horsepower and a pressure of 8 bar, will be a good work for simple use In the end, great job, thank you very much
cool build but what’s the purpose of the fan on the compressor?
Nice work 😍😍
Thanks
very nice ! i would have a oil bath aircleaner on it to help lube the system, and make oil drain refill with automatic transmission fluid :) but man what a nice little rig there!
Work is good, but there is a shortage
You must make a frame around the fan, as well as filters to filter the air entering the refrigerator compressors
The regulation of the hoses should be better than what I did
I repeat my thanks to you
there is no need for the fan at all, you only need it for the condenser. it serves no purpose here.
Cool
bravo majstore 👏👏👏
Hvala Brate 👍😁
An excellent job done and effective I might say. I would like to make an air compressor from an used car GPL gas tank and an old wheel compressor. Is there a way we can get in touch and change some opinions about this? I would really appreciate your advice🙏
Thanks
Nice Idea!! √√ BUT you should SHOW the WIRING -> PRECISELY & EXACTLY, so every one can do it himself / HER-self
Yes, you are right
@@MrDKDIY … would be an Idea to do a SEPARATE Video, just for DEMONSTRATING purpose how the wiring is done ;-)
good night ! a query with that engine reaches 8 bars of pressure?
Yes it does
@@MrDKDIY thanks Bro!!
ได้ความรู้มากครับชอบคุณ
Sir kindly show how the wires coneck from the 2 compressor all wir conections
How about lubrication for the motors (normally provided by the oil filling?
Refrigeration compressors such as these are filled with oil and sealed when they are manufactured, so no fuether oil is needed.
good video
After 1 years ... Can u upload 1 video to review back this compressor ? Tq ...
Yes bro its still working wery well, so i make video for DIY compressor after 1 year working thanks for giving me your idea

Where are you from ? And what is your native language?

Do you really need to fan to keep the compressor motors cool?
Usually, fans in refrigeration are usually to help cool the gases.
If the tank can handle more pressure than the compressor supplies, willnthe compressor keep trying until it gets there days later? Or will it burn out trying and never get there? Can the compressors take turns to complete the job? I need 3600 psi.
Hello, I did not understand why you installed the fan, what is its function? Best regards
cooling the heat of both compresser
Compressors get very hot when they run for a long time. Some people weld cooling fins to these things. Dude made a professional grade system.
what is the function of a fan in your planet?
The exposed fan blades are a nice curious children fingers chopper, specially when it starts unexpectedly.
Thanks for making this video, but just leave that music out. Say a word or two instead.
I thought it was great ! I would like to get the wiring diagrams please?

Cool concept. Don’t see it holding up to much pressure tho.
sorry for my english, i have a question...which is the fan function?
Don't forget the leaf blowers and all the cars that sound like them!
Okay Man thank you
Thanks to you for your support
LIKE THAT BUT WHAT U HOOK THE FAN IO?
one question why i s the fan facing to the back instead of bolwing over the comps.
So how do you keep the ac compressor from overheating? Also, is moisture build-up that much of an issue? Im making my own and have hit a small speed bump just about to tie in pump to tank, how long did yours work after conversion?
moisture - seen some cheap tire inflator compressors spit out water. lot of water squeezed out of air. they should have dryer/drain or somesuch
