Silent Air Compressor (DIY) 

First

Love that rooster in the background who started so many times but barely had a chance to finish :)

Once the galvanic corrosion depletes the threads on that check valve, you will have a 100+ psi bullet with a HUGE potential to kill someone. Imagine sitting down on the ground to drain the water when it flies off into your eye. Given there is no rifling, no containment, that screws shape, and the pressure exerted on it, the potential for it to tumble is high. So it enters your eye, and hits your brain. Caskets are more expensive than proper air compressor parts. Engineering your own parts is one thing, but not when it comes to pressurized loads. Most people do not realize that little things such as using dissimilar metals can cause catastrophic accidents. Do not solder -- braze it. Do not weld the tank unless you are a professional welder. Fill the tank with water, drain, then dry; Don't weld a tank full of water. Match the maximum working pressure (derate it by at least 20%) of the tubing (look it up from the manufacturer given the diameter) to the check valve you intend to use.

Well done, very nice and great finished look. For next build, you do not need a oil drain plug in the bottom of the compressor. All the oil in the compressor ends up in the bottom of the air tank, so you need plug there. To add new oil to the compressor, just dip the inlet tube on the compressor in a cup of oil and it will suck it up happily :)

I just love all the safety gear

Welding in flipflops and wool gloves. Guys a genius!

There is oil vapor heavily coming out of the compressor actually, so you need to separate it and lead it back to the third (sealed) pipe end coming out of the compressor, because that is where it has originally been filled with gas and oil. The oils they use in these compressors are mostly synthetic ones (e.g. polyolesther) and they cause irritation with skin and lung contact, so you should keep that in mind. Cheaper (like noname chinese) compressors have very thin, waterlike oil in them, expensive ones (like Danfoss) have thick and yellowish oil. I have just disassemled a few of these, and used one to make 4bar in a vessel, but I think it may also be suitable for painting compressor, however, you need to carefully lead back all the oil to the compressor.

I gave this a thumbs because I think this guy was welding naked at one point lol n the sound effects made it

The word "explosive decompression" comes to mind when looking at those welds.

boss tanong lang po , ilan minuto kaya mapuno ung air tank mo..palagay ko mejo matagal yata..???

Your rooster sounds very funny at 1.5 playspeed

Again you surprise us your machines, they are very easy to make. Greetings from Colombia

Also a Filipino DIYer here! Amazing works!!!

that last wiper is awsome hahaha

This is the best one I’ve seen

Amazing Compressor creation 👍👍👍

Esta muy lindo y funcional el proyecto, debes ponerle a trabajar el espiche del aire que queda en el tramo del tubo de salida del compresor, asi ayudas a evitar que toda la presion de aire del tanque una vez que el compresor alla alcanzado la presion de llenado que hayas fijado en el presostato la reciba el flaper de alta, tienes la opcion solo que le pusiste un tapo, ella va con una manguera de la valvula antiretorno de tres vias a la parte de abajo del presostato. Yo hice uno pero con un compresor de aire de 15.000 btu, de botella, lo que no me gusta que igual estos tipos de compresores escapan mucho aceite salida, y a su vez llenaran el pulmon. Saludos..

you got the active and neutral arse about on the switch, input side. Nice welds bro!

Can I skip the beginning and start by welding the legs on a full tank of propane?

Nice work matey, now hunting for a scrap fridge!, i need a quieter compressor for winter, so i can air-brush indoors..im not freezing my arse off in my workshop!!Lol!. All the best.

Saludos cada cuanto tiempo hay que cambiar el aceite para sacar e agua del compresor y no sufra daños?

That’s absolutely adorable❤

Nice, Sek this is cheap & easy to build in my place ( i will made like you video) thank's a lot sek, keep roll with new video other device.

love yaa deadly winter gloves for welding

Very well presented and executed good job.

Too bad it takes all day to pump up the receiver. How do you pass the time while getting up to pressure?

Wat are the uses of this compressor??? Can I use it for pneumatic brad nail gun and a pneumatic orbit sander?????

04:40 Sir, the earth has always to be some 1,5cm to 2,5cm longer by law, so if somebody tears off the cable, you will still have some kind of security mounted to the plug! It should be the last to be torn off

Es cierto que cuando usas un motor frigorifico para hacer un compresor de aire, es mejor ponerle aceite 10w40, en vez del aceite que lleva?

Una observación como sugerencia es que tienes dos tubos para la entrada de aire en uno le puedes adaptar un filtro de motocicleta para gasolina (purificar el aire) y en el otro poner una boquilla con una tuerca cónica cuerda interna con tapón para agregar el aceite ademas en la salida de aire del manifould ponerle un filtro para retención de agua y aceite. pero en si es muy bueno tu proyecto felicitaciones.

puede rin ba yong mga compressor ng aircon gamitin "window type" sir?

Bro... Fantastic job! Looks great and works really well!

extreme make. ayos yan para sa industrialization ng Pilipinas.

A big tool company should sponsor you.

I like your welding bro

Great craftsmanship.

Very nice video.......and big respect from Zagreb/Croatia

Pano ko sir malalaman kung gumagawa yung fridge compressor? Tutorial please? Thanks in advance

*Whether or not it is used for PCP air guns* 🤔?? Please reply

Is there a drain on it to get all of the water out though

Thank you for sharing ,nice job! but you have to handle the problem that there is lot of refrigeration oil go into the gas tank, otherwise the pressure air come with oil.

I thought you needed a start capacitor when using sealed units. Can someone explain this to me please

another well deserved repurpose. keep it coming.

at the end of the video, clean the oil of the screw with some underpants?

Ha ha ha ... Very creative. I want to develop it into a PCP pump. Thank you for the information.👍🙏

Can I use an AC compressor? You drained the oil and replace, what kind of oil?

I put a 1hp compressor onto a 50 litre tank.replacing a broken "rattler". Perfect.

what size thread is required for the T check valve socket? is the 1/4 reducer NPT or BSP? and where do you get the extension ro mount between 1/4 reducer and pressure switch?

I think its a Filipino because it is a LPG Tank brand in the Philippines

Thanks for a very useful video. But can u tell me how to set min & max pressure? Thank you!

. 'Silent' be like a fridge running permanently, nice job keep at it fridges are noisy when trying to sleep

еще фильтр добавить на входящею трубку, что бы пыль не набиралась в компрессор, а в целом получилось хорошо)

Why puts water inside the bottle ??

did you add a water drain on bottom of tank? its not shown on video. also there is no air line for pressure sensing switch?

Thanks, a wonderful idea

Very Good build. Exactly what I was looking for. Thank You!!!

I need your answer please. This is an hermetic compressor. How do you deal with oil since they don't have reservoir? In refrigerators, oil and coolant gas are mixed and go through the whole circuit (condenser and evaporator)

can i make it without tank

Need to dump the refrigerant in the air compressor?

not sure if the compressor modified already, if not then the motor will run out of oil and causing damage.

At last you done good use of yours underware for wipe compressor oil good skilled man 😁😎👏🛠⚒🔨🔧

sir pwede po bang malaman kung ano-ano yung mga needed materials nito? Kasi mag a assemble sana ako ng ganito pang airbrush ko DIY.

Very nice bro, DIY at its finest! :) I also build this type from a fridge compressor. But one problem i have is the compressor pumps out oil a lot. one charging for about 5mins and it pumps oil 50ml. Pinalitan ko na yung orig oil at nilagyan ko ng ATF madami din kasi akong nabasa na okay na pang subtitute ito sa comp oil. ngayon diko alam kung mag motor oil nlng ilagay ko or korek nlang yung compressor o kung ano mang problema? Need your advice pare! :) Salamat ng marami.

what was the problem with the oil? do you have to do it often?

Thanks for your video….yours was one of the first that caught my attention and got me interested in this. Since then I’ve made a number of these compressors for others (from used, broken, craigslist, and dump-finds with Porter Cable, DeWALT, Craftsman, Campbell Hausfeld, Huskey, Bostich, and Central Pneumatic tanks (2 gal to 20 gal)). ALL working great (and none having experienced temp overloads filling from empty- which surprised me on those greater than 8 gal). TWO OIL DRAIN-FILL QUESTIONS (answers will help not only me,but all others making these units) (1) With a refrigeration compressor with 1 pressure tube and 1 inlet tube (assume “without” any manufacturing installed crimped Freon fill tube) I’m having trouble draining/filling oil (while tilting compressor towards the inlet tube) due to "either", various bends in the inlet tube, OR due to no air escape route while draining. Any suggestions how to drain/fill with only 1 inlet tube (2) If there are no answers to (1) above, I assume a last resort might be to drill a hole in the compressor and Braze a fitting into the hole (that can be capped or plugged for drain/fill). Can this be done with a Bernzomatic TS8000 torch using Mapp gas? Issues are not knowing what's on the other side of where you're drilling; getting chips into the compressor while drilling; heat having some bad affect inside the compressor while BRAZING. Thanks.

It’s amazing how much pressure one of those motors will produce. My dad made one with the motor out of an old freezer. He had a big tank and set the high limit to 300 psi. He set the pressure back down when he blew a low tire off the rim. He was lucky not to get hurt. 😀 They are slow to build pressure though.

hello i have a question how to used an ac compressor with the help of an electric motor to transfer lpg gas to a lovato gas tank?

Regards .. How long does it take to change the oil to remove water from the compressor and not be damaged?

Clean work design

Refrigeration compressor are not made to compresse air . the moiture of the air will make the oil turn acidic and it will start eating the varnished of copper winding and after some month the compressor winding will just ground .

very good work

I noticed that on one side of the wiring you put neutral wire above live and on the other side revered this even though bothe sides are marked neutral on top live below, why does it not blow a fuse? Thanks

Uy unang ambag sa pinas nagustohan kotong compressor nato maganda to para sa shop namen😄

Bahut bdhiya good luck video

Galing tlaga ng gwang pinoy..

Got those drill saw bits a couple of years ago through your affiliate link on a prior video and very happy with them, thank you. Tempted to try this project, though after having my last compressor stolen I'm more inclined to wait until I relocate to a home with a work shed I can lock

I love this!! Welding with grandma's gloves in flip flops. Either Mexico or China. Although both are the same just smell differently. However, TRULY silent air compressor. These in the US that utilize fridge pumps are still around $1000.

you do not write all, what is the black device, how much oil you input etc. please specify more.

Wow are u from philippines?

esse cilindro que você usa para armazenar O ar é de que.?.?.? quantas libras você coloca...

Pinoy talaga hahaha nice bro

Saan po pwede po office nyo po at kun PLDT or contact po

Very good your compressor my friend, I'm crazy to ride mine too.

Conception is really good and the work too but if u want to use it for something else then for airbrush that has to low power and if u'r using this for airbrush u don't really need such big tank u can instead use old fire extinguisher or CO2 tank from this wierd home sodifiers but the work what have u done is really good

Idol ka talaga sir!

Was the start run capacitor already on the compressor?

StorageDear Sir & Madam, I need a help from you people. I am novice on this field, till this time I could not find out how much air pressure (PSI) is safe for various cylinder for storage purpose. I want to make a portable air cleaninig system from a refregerator compressor, viz. foam car wash rig, tyre inflator, engine bay clining system etc. For these purpose I have in mind that either portable gas stove cylinder or fire extinguiture cylinder so that I can carry the system from my 2nd floor flate to ground floor.Please guide me regarding this. And also please guide me that how much PSI & CFM need along with the volume of the cylinder wiil be enough please help me.

Sir gandang umaga po..tanong ko lng sir kng pwd ko rin ba lagay ang compressor nang refragerator sa 50 kgs na tanke?at mga ilang psi or bar salamat po.sa sagot

Wow! Please put the material list with measurements, here in Brazil some item can’t easy to buy

Excelente los compresores de aire.con la bocha de heladera . impecable los trabajos abrasos

Wow even with 3 or 4 of those pumps on there it would still be to slow for most uses.

Is there a way to do this without welding? I have zero experience in that. I do need a quieter compressor however

Not placing a pressure switch on a the tank kinda defeats the purpose of having a tank in the first place... Basically when the tank reached a certain pressure threshold, the compressor should automatically shutoff. I believe that small valve outtake you just closed off with a screw is to be hooked on a pressure switch.

Great project with some minor failings. Pressure vessels charged with gas/air need to be properly tested. This is one of those home RU-vid projects that need a public don’t try this at home. Buying a new propane tank is great, it is a certified pressure vessel, but the moment one cuts, welds or modifies the original vessel all bets are off. Hydro test the vessel to 150% of operational pressure, use water to test. If a failure occurs the press release is far less dangerous than trying to pressure test using air. Air is compressible where water is not therefore the energy release is far less catastrophic. Also don’t use galvanized components in your construction, use black iron components (actually steel with an oxide coating). Remember this project going south on someone can be deadly. Anything that holds 15 psi or greater is a pressure vessel. Remember the 90 to 100 psi is per square inch, now calculate the total area of the vessel and see what the true force being held. Good luck and good practices, stay safe and think before you leap.

Nice video and actually gumawa din ako nyan (I get the idea on this video) di nga lang kasing ganda ng sayo. Thanks for making this video

Bonjour très bonne idée en plus j'ai vu que vous avez mis une vis de vidange d'huile et une de remplissage, ma question est la suivante, combien d'huile remettez vous en tout ? Merci

very nice

Sir, ano po gamit nyo na welder.. inverter ba yan or transformer?

Good Idea but problem is oil from compressor in air

Bs untuk isi tabung pcp gak ini gan??
