In general, a normal man without a fight will not throw off just so old non-working fridge with Compressor!
We have such a common feature, they say "Well, where are you throwing away? Come in handy ever! " ..
And we decided this "someday" to turn into "And let's do!"
Here is such a weighty unit, we reeded from an ancient box, similar to the Soviet refrigerator brand "Saratov".
The task of dealing with all entries and outputs, check the performance, in fact it turned out not difficult ...
Tip! Be careful, from one tube will definitely run oil during coloring!
Zatarajtel T. and Stone this cylinder and we started with a calm soul.
While the primer was dry, cropped "ears" for springs and made a mount from the profile pipe (20x40).
On a row with a free compressor, we got conditionally free (50p pcs) These kegs are about 14 liters (failed to find the volume among the factory characteristics) capable of keeping the breathtaking 36.8 atmospheres! (claimed critical pressure), although the protective valve will work much earlier ...
Willingly agree without exposing the last digit to doubts, because The practical way was established that the usual plastic bottle from under soda holds 4 atm ... (the costs of youth, the torture of the mind and all that :)
They cut off extra from the handles and drilled holes under the heel on 8mm, and also under the copper tube 8mm.
We wanted to find fittings for a balloon from under Freon, as a result, we decided to boil ordinary gas (native fittings specific, as a result, the price tag for accessories) ..
The framework of the carcass (30x40x74cm) was taken profile pipe 20x20mm, 6 meters with a thickness of 1.5 mm to facilitate the structure, however it is still very strong and total weight in the end amounted to about 18 kg ...
We make studs for cylinders, then the grid for sidewalls.
The profile pipe 10x10mm went about one and a half meters. To grab the grid to the pipe, graphite contacts from the trolley (used) were needed.
Go to painting
(Of course, we first collected and checked, about it further ..).
Even passersby cannot resist paint from the clerk :)
Start assembly
Rubber gaskets cut out of the cycling chambers, they do not allow paint to scratch, because Motor has vibrations. Aluminum substrate serves as a radiator.
Here it is clear that it took, a detailed list at the end of the article ..
Pressure reducer, relay (discharge on the desired value), gun and hose (10 m for the garage seemed short)
Manometer, fittings for cylinders and tubes, tee, fum-tape, copper tube, safety valve.
Tip! Pneumatic fittings can be not Iron, I had to go shopping, in Baucentre (not advertising) found that you need to check the alloy, maybe brass!
Oil separator (plans to set out), fuel filter and relay to start the refrigerator motor.
In the design, there is significantly enough oil separator (a glass with a paper filter) first needed for the painting, for insurance, because old compressors can spit with oil.
That's what we did :)
For work
The compressor works quite quietly, a very heat engine, for example, with the support of 4 atm in the receiver, it does not heat it almost, but when 5-6 ATM is reached, it is heated up to 50-60 degrees and it cools down (more than 8 atm have not been tested). 6 atm is gaining in 16 minutes.
Purge the video card of the smart table with a PC inside.
A small seed to our next project :)
Tip! Who will collect something like that, one balloon from under freon as a receiver is catastrophically, disappointed only. Take two or other containers with b about The volume, only not a gas cylinder)) terribly heavy design will be with a small productivity.
Second Council: Compressors in old refrigerators have less productivity, in modern refrigerators they are more powerful and productive! In addition, most with electro-thermal protection systems.

Conclusions: If you are overwhelmed with enthusiasm and do not find yourself a place or you have a living compressor and you want to breathe 2nd life into it or someone to prove Ile even yourself - go ahead, dare! (But after you familiarize yourself with the list ..)
Although another bowl of scales outweighs common sense, according to which there could be a tyrnus 3-4 and acquire a ready-made factory and not a handicraft, saving time and strength)
Everyone, as they say ...
