Kostas ,
Thank you so much for your detailed explanation of the build , and in particular the modification of the pressure switch .
My first build failed due to this not functioning, resulting in a burnt out motor , however , following the instruction in your video, the modified pressure switch works perfectly and I have a most useful compressed air system in my small workshop ,
Thanks again ! .
Wow thank you so much for you feedback. I'm really glad that helped you. Really appreciated
Very nice. What is the fittings 3 o’clock to the pressure meter Thanks
Very clean build sir
Glad to see a new post, it’s been too long!
Thank you so much for your support.
Thank you for this informative video kostas! I just built mine but had some issue where it doesnt create enough pressure to my tank, my regulator and air pressure gauge doesnt seem to read the tank. I wonder what causes the problem. btw I used condor m11 for my pressure switch. Thanks again Kostas hope you read this comment!
Hi Czar. Better late than never! Did you manage to find a solution? Low pressure usually is air leakage or not so strong compressor.
@@KostasMiniatures Hello Kostasiii, Yea the thing with mine was it is a prebuilt air compressor using a fridge compressor and wanted to add an additional air tank
( preview.redd.it/z96pojv4hyw71.jpg?width=960&format=pjpg&auto=webp&s=13b6d72394b0768b2f89c4b2d72cfcc0e851e5e5 )
I was able to add a pressure switch as well as the new tank but yea the pressure works now there's some leakages that I might need to cover with Teflon tape.
overall the compressor is working but when left alone with air inside, the day after the tank is empty which tells me there's leakage. anyways thanks for replying man! I appreciate it
Thanks for the video very informative, this tank called Expansion Vessel, they have a rubber membrane to isolate air from water, did you have to remove that rubber tube inside it or it is already busted? Thanks again
Thank you for you kind words and the inform about the tank. No I didn't removed the ruber tube. I left it as is
@@KostasMiniatures Should be ok I will do the same, THANKS
@@KostasMiniatures If you haven't removed the rubber membrane but added a valve at the bottom, does it make any sense? The air will only be in the balloon, and so will the condensate.
Hi, what about the wiring for the pump? I have 3 wires running off from it, 2 which where for the thermostat, and one to the light inside the fridge
Hi!
These water tanks has a thing I the back. Not sure what it is for, but what did you do with it?
Picture also would be appropriated.
Just a nut. I think is part of the base and might help at the original placement
Under the plastic cap is a standard automotive air valve for filling air and generating pressure. The liquid is in the membrane and the air is in the rest of the tank, just like in membrane hydrophores. In this case, the valve becomes completely unnecessary.
How long would you say it takes for a compressor built this way to get up to max pressure?
It depents on the size of the airtank. This one takes about 4 minutes
Hi, I would like to build this but I am a little confused, How do you stop oil from the compressor to go to the air tank, I mean the compressor is full of oil so how do I stop that oil from getting into the air tank ? Thank you
I think they run them dry without oil , so not sure how long they will last.
I don’t know what the max pressure that compressor can produce, but perhaps you can use a high pressure compressed air tank that can handle more than 3,000 psi to build a air compressor for high cfm needs.
Thats over 200bar!, even expensive commercial ones operate at a maximum of about 12 bar.
sir Kostasiii Miniatures can i ask?do you have an idea how will you know the PSI required for the unlabel tank.coz i have a junk fire extinguisher but i dont know what is the appropriate PSi for that tank.i hope i caught your attention.thanks.
Will it have enough pressure and flow rate for driving nails?
What is the typical pressure maximum of fire extinguisher bottles?
Certainly, it is possiple, you simply need to ensure that the refrigerator motor does overfill the tank rapidly. Otherwise, you risk either putting excessive strain on the motor, leading to quicker wear and tear, or depleting the air supply in the tank.
I would like build same compressor
My question is how long Time to take full up for 0-8bar.
Thanks.
according to air compressor. Usually 5 to 8 minutes
What sort of cfm output do these refrigerator compressors have?
I don't know that but I think you can find it at the specifications of the fridge... maybe
@@KostasMiniatures
The manufacturers data sheet for the compressor will give you the displacement, (in cc`s) which you multiply by 2900 and divide by 1000 for litres per minute. This the the theoretical free air output, the real world output will be somewhat less, typically 10%-15%
πολυ ωραιο βιντεο φιλε μου..! εχεις σε παρακαλω ενα εμαιλ να σε ρωτησω κατι για τη συνδεσμολογια του συμπιεστη γιατι μου ριχνει το ρελε η καπως να μιλησουμε.. εχω τον ιδιον και θελω να φτιαξω και γω κατι παρομοιο..Σε ευχαριστω

Hi what will break in the pressure switch if we don't replace valve ring...don't understand please explain thanks.
I'm not sure about that. I'll recommend to search for the manual of the compressor
Can we use that small tank compressor for Air Impact wrench ?
Yeah, but you wouldnt be able to use it continuously I guess, you need bigger bottles or a much faster compressor.
There are two inlet of the compressor wich one should use as inlet of them
the one that if you put your finger on it, will feel a small suction
How can I get a clean air and how can I catch the oil vapour so the compressor doesn’t burn
Good job..👏👏👏
Sir what about behind tube.. There is a niple right.. Close or..
Thank u
Hi what tube do you mean?
Good morning.. I mean that tank air compresor.. There is a niple or not
Thank u
@@mokhamadansori6752 at the compressor, are 3 small tubes. One is the intake, the other is the outtake, and the 3rd is the closed on that is for maintenance in case the technician want's to add cooling gas
Kosta m gt vgazume to elatirio? An den afairethei ti ginete?
γιατι το ελατήριο ειναι πολύ σκληρό και δεν θα κλείνει ποτέ η ανεπίστροφη. Δοκίμασε το και θα δεις
How do you top up the oil and how often?
From the tube that the compressor blows the air you can add some thin oil like the one for sewing machines. It depents from the usage but I haven't refill 4 years now
@@KostasMiniatures thanks! I’ve built the same one, was afraid it can die since I don’t how mush oil it consumes
Hiya what’s the diameter of the smaller tube? Please
4mm
@@KostasMiniatures thank u
You didn't do a very good job of explaining why the pressure switch needed to be modified and how what you did would work. I don't see why the pressure valve would depend on the VOLUME of air moving into it, just the PRESSURE of the air at shutoff. I could be mistaken-can you expound on why you did this?
👏👏👏👏👍🇪🇸

残念ですが冷蔵庫orルームエアコンの圧縮機ではそのままではモーターが焼き付きが生じます冷やす対策をこうじて下さい。冷媒が入ってない分圧縮機は高温になってコイルが焼けてしまいますよ。
a refrigerator compressor got Oil in it .....use a refrigerator compressor with out Oil??? or not ?? das not brake with out oil???
