Functionally operates just as it should kzfaq.infoUgkxiiMg_x4gIWeXMWfBnDdRnME4qJUAva4w holds pressure perfectly when not in use. Glad one of the other reviews pointed out that the bottom pressure release valve was open; thought it was defective at first.

My step dad made me one 30 years ago when I got into airbrushing, worked great.

I did a similar thing as this 20 years ago. I used a central air compressor and a hundred pound propane cylinder for a tank. Been using it for 20 years now.Its so nice & so quiet

with out a doubt........absolutely amazing! hat off to you sir.

A beautiful fabrication job worth many dollars. To bad potential manufacturers of quiet compressors don,t take the hint and put something like this on the market for a reasonable price. Yes, how to remove the oil from the air discharge and maintain the compressor oil level is a good point.

Very cool i never thought a refrigerator pump could make that kind of pressure

Brilliant! It is better to fit tapper on bottom of tank to drain water which condensated in it. Cheers from Indonesia

Thank you!! I just made mine today and it fills my car tires very fast!!!

Great idea! I was wondering about the oil in the compressor too where a fridge is a closed system, this one is open. Still looks like a fun project! :)

Was doing this back in the 80s with 4 pumps inline (just saying)😁

Nice job 👍🏻

Um super like do professor Marinho do Ferramentas e Dicas do Brasil

Extraordinariiiooooooo absolutely fantasticoooooooooo that compressor 😲😲😲😲😲😍😘😍😍😍😍thank you for sharing this beautiful video excellent explained fully detailed information about how to make a compressor 😉😉😉😉👀👀👀👍👍👍👌👌👌👌

Estupendo trabajo compañero. Pero veo algunas medidas de precaución que usted no ha instalado en su proyecto. Y son muy importantes. En primer lugar, no veo que haya instalado una válvula de seguridad. Eso es muy importante, por que si en un momento dado el presostato se avería podría a llegar a reventar el calderín o alguna de sus piezas asociadas. Tampoco veo que le haya instalado un filtro de aire en la entrada del compresor. Otra cuestión no menos importante, es que estos compresores de nevera, están diseñados para trabajar en circuito cerrado. Con lo cual, usted va a tener una pérdida de aceite muy importante cada vez que utilice su proyecto. Le recomiendo que a la salida del compresor, instale un separador de aceite. Otra cosa importante, debería haber instalado una llave de purga o evacuación de la condensación que se produce dentro del calderín. De lo contrario, llegará el momento que corrompa el interior del calderín por el óxido. Supongo que habrá instalado la válvula anti-retorno, otro detalle muy importante. No tome mis palabras como una crítica negativa, todo lo contrario, me ha encantado su proyecto. Solo sugiero algunas mejoras muy importantes en lo que a seguridad se refiere. Un gran abrazo..... Great work partner. But I see some precautionary measures that you have not installed in your project. And they are very important. First of all, I do not see that you have installed a safety valve. This is very important, because if at any given time the pressure switch breaks down, it could burst the boiler or some of its associated parts. Nor do I see that you have installed an air filter at the compressor inlet. Another issue, no less important, is that these refrigerator compressors are designed to work in a closed circuit. With which, you will have a very important oil loss every time you use your project. I recommend that at the outlet of the compressor, install an oil separator. Another important thing, should have installed a purge key or evacuation of condensation that occurs inside the boiler. Otherwise, the moment will come that corrupts the inside of the reboiler by rust. I suppose you have installed the anti-return valve, another very important detail. Do not take my words as a negative criticism, on the contrary, I loved your project. I only suggest some very important improvements as far as security is concerned. A big hug.....

brilliant and easy to make (with the right tools)

Man, that was so much easier than buying a can of spray paint. Thanks for the tip!!

Spectacular job man. Thanks for sharing 🙏

Parabéns. O melhor projeto homemade do KZfaq. Super simples e funcional. Top

I liked that this compressor is very quiet. Bur for how long would it work

thanks for the advice, actually built one with two reciprocating motors and works well (also super silent and cost -100 if you do it diy)

Great video Thanks

Great idea! Shame you did not last the parts as I do not recognise some of them.

Built one of these in the 70,s. still use it today in my workshop, given me years of good service, a couple of years ago i built another for a friend of mine to spray his models with a small airbrush. now i see they are for sale in our local machine shop at very expensive prices, should have patented it in the 70,s, but hey ho

Great work...

Brilliant idea and did it after but there seems to be oil coming out with the air and what happens if the oil of the red compressor runs out? Be well & safe.

A great project and very well done. Supurb result... :)

Nice I love this idea.

Looks great. How do you deal with the oil the compressor spits out and paint contamination?

Very very good, brother! Amazing!

Very professional...

Dou os meus parabéns pela grande ideia nota 10. pela a criatividade OK OK OK .

... отличная приблуда для гаражных работ, случайно не продается, а то куплю..!

A DIY SILENT AIR COMPRESSOR FROM A REFRIGERATOR MOTOR,....IS EXCELLENT!

Wow.. amazing 😉

10 bar??? very good job man!

Do you think the power is sufficient to operate a pneumatic chisel to do metal engraving?

1 safety concern - lack of pressure relief valve and have you tested the tank? 2 - how are you going to drain the moisture/water? I like the project and its execution but it's lacking a bit ;)

Este foi o melhor vídeo dos que eu já assisti parabéns Deus continue te abençoado

This is impressive. Thanks for sharing

Outstanding!

love the paint gun at the end. you´re a daredevil letting this small compressor go up to almost 150PSI !!! should definatelly add a safety valve or recalibrate your switch to lower it to ....maybe 90PSI you where lucky to find such silent almost mute fridge compressor

These were commercially made about 30 years ago by Devilbis. They were called silent airbrush compressors. They cut the compressor around the circumference at the seem. Dumped the oil and replaced it with an air compressor oil. Probably Mineral spirit oil. A special clamp similar to a huge hose clamp that fit around the tank to hold the top and bottom and a rubber seal together. I had one. It was absolutely silent. You only heard a psst when it turned on and off. perfect for an apartment setting. I am not sure if they still make them. I no longer do airbrushing. The unit cost around $350.00 back then. You could buy the oil in art supply stores by the liter. One of the copper tubings was for refilling the oil. You only use 30 to 40 psi for airbrush. It also had a tank about the size of a medium sized hand job fire extinguisher. It is obvious this one is pushing 140psi ouch!!

Diy.bueno tu proyecto del compresor.pero para soldar ángulos.comprate o fabrica(es muy fácil).ingleteras imantadas.saludos😁

Good work

Manchester type propane tank...nice

They make a great a/c vacuum pump also.

Просто супер.Спасібо ребята.

Bro can u mention some items which was used in the video ?

great job👍a quick question, my compressor spreads oil. how do u stop it?

Hello is an interesting project. I have one question, if the piston is not lubricated and works only on air, will it be exploited? Will it be durable?

nice project, please air parts info and links

Really silent!Thanks

Great! So silent! Nice done! ;)

Can't believe how quiet it is. I have a tank from small Craftsman compressor but the compressor is bad. I'm going to look to find an old running refrigerator compressor and take parts off from the original set up to make one so I can work in my small shop with a lot less noise for small projects. Thanks for sharing.

You need to replace the oil in the compressor,it is hygroscopic,and therefore absorbs moisture! At the entrance to the compressor, put the filter and will be very good!

ive got a lot to learn about fittings and which metals i can solder/weld/glue together

Two things missing: a safety valve (fridge compressors can go well over that bottle's limits) and a water purge valve at the very bottom. And also I put a one way valve so the compressor can start more easy.

Please add a safety valve, this compressor reach about 300 PSI.

Parabéns pelo trabalho bem feito

You are awesome!

Is this project use in refilling bio gas also

At about 9:33 you made it so it can not be taken apart. As well as what everyone else mentioned about safety issues.

40 years ago my dad made a compressor from the fridge unit from a milking machine and used a gas bottle a few years later he was able to afford a proper compressor for the business. the new compressor is now 35 years old and has been used every working week.

Wspaniała robota

This is awesome

I like this...Jozz!!

Bravo vraiment c'est du beau travail 👍👏😊

Good job

Nagyon ötletes, én is hasonlót csináltam, csak én egy gyári kompresszor tartályára szereltem rá a hűtő motort. Bár a festékszórás az túlzás, mert ahhoz nem termel elég levegőt, és még a 20 literes tartály sem pufferel eleget, ráadásul 17 perc, mire feltelmeli 6 bár-ra. Kerékpár, autó kerekét felpumpálni, asztalról a koszt lefújni, arrakiváló!

me gusta el video es una asignatura pendiente, que en cuánto pueda me pondré manos a la obra

It will work (for a while) water in oil and lack of lubrication issues is what makes it impractical. Harbor Freight..........save your weekend.

Nice...you should add oil feedback and replace the oil with mineralic oil because the ester oil will accumulate water

If you do this again I would like to recommend some changes. 1 - Drill and tap the base before welding the tank on (2:22) 2 - Put the handle of the cylinder for the container in the center of the rig to help you carry it. Don't cut it off (1:46) 3 - Don't drill through the wall of the tank, this compromises the strength of the tank. Instead put a T pipe to act as the inlet/outlet (3:27) 4 - Don't weld the pipe into place as this prevents the machine from being taken apart (7:27, 9:36). A flexible hose and clamps work just as well. 5 - Make sure there is a way to lubricate the motor once in a while. This refrigerator pump was meant to pump refrigerant, not dusty air. 6 - Make sure the compressor can turn itself off. I don't know what the limit on your tank is, but on mine it is 100psi. 7 - You will need to find a way to take the compressor apart to drain the condensation. But what do I know? I've just got a diploma as a welding and fabrication technician, two years as an industrial powder painter and three years with an air brake endorsement.

excellent Very good

i used to have one of those, although not nearly as elaborate. worked fine for years until the compressor locked up.

I was experimenting with an old fridge compressor. Attached a connector to it and connected it to the output of an old loud crappy compressor. The fridge pump got the tank up to 8bar quickly, so I replaced the old loud pump with this one. Now that is actually connected via the valve to the electric switch and safety stuff it's no longer pressurizing the tank. The electric switch is hissing. Is the switch malfunctioning or do they work by letting some air escape and are therefore not compatible with every pump? Can I fix this somehow?

good job bro

I hope I can do as well and be like you, I wish you and everyone a good time and happiness

After the "rattler" stoped i put a 1.25 HP used Kompressor onto that tank.also did one for a friend.third of half HPs take to long and no good for spraypainting.

Excelente, meu caro. Que capricho! Tudo muito bem feito, sem gambiarra. Muito bom! Estava pensando mesmo em utilizar um liquinho pra reservatório. Já clareei minhas ideias! Te agradeço.

I would like to know where to get the crimping tool that was used. :) Oh, cool compressor too!

Excellent work but I have the doubt of how to do so that the compressor does not do the work it does when it is connected to the refrigerator ... that is, it rests by the action of the Relay ... because I have one without a tank and works for a while So when I disconnect it, I have to wait a while for it to work again. I would appreciate your guidance on this ...I do not speak English.

Excelente!!!.

it would've been nice if you listing all the parts and sizes needed

Thanks for the video . I'd like to do this project can you give a list of the parts needed for its completion.

Nice work, but how much SCFM?

Genial !! , Bravo !!. Saludos desde Madrid Spain.

Koja je snaga tog motora od frizidera i koliko mu treba vremena da nadruka od 0 do 8 bara?

excelente el trabajo pero me quedo la duda de como hacer para que el compresor no realice el trabajo que hace cuando esta conectado al refrigerador...es decir que descansa por la acción del Relay..pues yo tengo uno sin tanque y trabaja un tiempo así y cuando lo desconecto debo esperar un buen rato para que vuelva a funcionar. le agradecería su orientación al respecto...

muchas gracias por enseñar.

can I use this refrigirator motor as a vacoom pump?

Will that frig motor fill a 21 gal central pneumatic tank with ease?

So much nitpicking and negativity!! Great build!! It will last for years...

Question. Must remove oil in compressor right? And do you use both vacuum lines as input air?

Is this pressure switch gonna work with 12v??

Sehr gut. Kein sinnloses langweiliges geplaper . Gut gezeigt.😂

Yes, the fridge compressor is great regarding low noise but you will run into a major problem with water accumulating in the compressor and mixing with the oil in it and eventually producing a milky sludge and thus diminishing the lubrication quality of that mixture and sooner or later (probably sooner) burning out this nice and quiet compressor. Water in the adjacent pressure tank is not much of a problem as we can get rid of it in various ways, however, I don't know of any way to get rid of the humidity in the air that first get sucked into the compressor and it is that humidity turning into water once air compression commences.

Put a Reciever with a oilreturn to the suctionline, its like a ping pong ball that float on the oil and open a return to the suctionline back to the compressor!

super

i have 10 litre tanks what kind of fridge compressor i shall put to make air compressor
