Dear visitors of the site "", as you probably already guessed in this article, we will focus on creating a compressor do it yourselfand donors will be served by an engine from an old Soviet refrigerator. This motor, for its intended purpose, supports the forced circulation of coolant in the refrigerator, or freon.

The author of this invention took this principle and thought the motor drives freon, which means it can pump air) both simply and into the receiver’s bolon.
A good and most important thing is a very economical idea, because the master received almost all the details for free.

The principle of operation is quite simple, the motor is working, it pumps air that goes into the receiver, and then wherever you want, at least pump up the wheels, or connect the paint-remote control.

And so in order to understand everything, you should look at the photo report and study the list of necessary materials and tools.

Materials
1) the motor from the refrigerator
2) bologna
3) gearbox
4) adapter
5) reinforced hose
6) tape fum
7) pressure gauge
8) tube

Instruments
1) set of wrenches
2) pliers
3) screwdriver
4) knife

To get acquainted, the author first gives the opportunity to view the drawings and wiring diagrams, the compressor.

So the motor is removed from the old refrigerator.

Hoses are connected to the inlet and outlet, it is imperative to install fuel filters to avoid clogging the unit.

Then a manometer, adapter and gearbox are taken.

Everything is going together.

Connects to the receiver's balloon.

the refrigerator motor and the bolon are connected with a reinforced hose.

At the exit from the receiver, it is also desirable to install a similar hose.

Everything is connected and ready to go).

Also, the author filmed a video instruction on the creation and further operation of this compressor.

Thank you for attention.

That's right. It "automatically merges" when you cut off the tube.)))))). At least part of it ... I "spindle" flooded. But it is so arranged that the unit in the oil bath works. In the case when it works in a sealed closed system, the oil does not interfere - it is driven along with freon, and it flows back down. But we need air without oil, this is firstly. And secondly (and most importantly), the absorption of atmospheric air occurs along with the water vapor contained therein. When compressed, they condense! In a conventional compressor, you also have to periodically drain the condensate from the receiver, but here it remains in the oil and we get a red bubbly liquid instead of oil ...))))
..I read that a good expensive filter dryer at the inlet partially solves the problem, but is it worth it to bother ....

The problem is that the oil in which the engine runs from the refrigerator is saturated with moisture very quickly ..... I was told that the oil needs to be drained and poured on the automobile, I do not know 2 compressors lying around there is no time to try. By the way, homemade writes about the same thing.

The compressor from the refrigerator is able to give out 8 atmospheres ... I did not try it anymore, I was afraid for the receiver. But the performance is weak ... A gas cylinder from inflated to eight more than half an hour ...

Why different compressors in the pictures?
There was such an experience too ... The problem is that the oil in which the engine runs from the refrigerator is very quickly saturated with moisture. At the exit we get a foam from oil with water. A conventional dehumidifier cannot handle it. It is necessary to put in front of it a tall vertical pipe of a sufficiently large diameter so that the oil has time to drain ... Yes, and in this case it must be changed very often.
Occasionally pump up a wheel, or work with an airbrush - yes, fine. And if you exploit often ..... In short, I spat and assembled the piston from the engine from the old "Izh-Planet" and the electric motor ..... It rumbles, of course, but the productivity and life cannot be compared ....
.... And then, in general, I bought the simplest 24-liter, and I use it ...

Unfortunately, instead of the source, there is a link to Yandex, so it is unclear who invented the "bolon", the "fum tape" and the "paint-remote". It is not indicated at what pressure the gearbox is needed and what pressure the compressor generally develops. What kind of “reinforced hose” is which for irrigation?
But this is all the little things, because the article is a collection of little interconnected pictures from different designs, in addition, having nothing to do with the video.
