Today, compressor equipment is widely used to solve a variety of problems. Such units can be seen in workshops, production departments, factories and service stations. There is work for him in a private garage or house. At the same time, purchasing professional equipment for pumping compressed air is not cheap. Therefore, some craftsmen use a trick and make compressors from scrap materials.
This article will talk about how you can make a compressor for inflating tires from refrigerator parts.
Operating principle of the unit
The standard compressor used in refrigerators is an air injection unit enclosed in a metal container. An important feature of such a unit is the absence of special storage tanks. Two tubes extend from the metal container, one of them is designed to suck in air, the other to supply it out. When remaking the compressor, there is no need to change the electrical connection circuit; it works reliably and is quite suitable for solving new problems. You need to install an air filter on the existing pipes, and then connect the oxygen supply hose (with the appropriate adapter).

The content of the article:
If you have an old refrigerator sitting idle at home, taking up space, so to speak, but it’s a shame to throw it away, go the other way. Various DIY refrigerator crafts that you can easily make with your own hands will help you make good use of this popular household appliance.
This article will talk about what can be done from an old refrigerator. Of course, the article will be useful for those people who do not throw anything out of the house, but try to make the most of it to their advantage and benefit.
Top homemade products from an old refrigerator
An old refrigerator, even with a burnt-out compressor, can still be useful in everyday life. And if the refrigerator has not been cooling for a long time, then it can be easily used to store a wide variety of things.
Even in a non-working refrigerator, you can store vegetables and preparations for the winter. Of course, for these purposes, it is better to unload the refrigerator body as much as possible, remove the coil mesh from the back, remove the compressor and get rid of all the “internals” of the refrigeration appliance.
Again, for those people who cannot imagine their life without housekeeping, the refrigerator will be an excellent “base” for making a homemade incubator. Since the body of the refrigeration device retains heat perfectly, the incubator from the refrigerator will not cool down for a long time, which is the key to its successful operation.
In order to make an incubator from a refrigerator, it is also better to get rid of everything unnecessary and superfluous. You will definitely need to buy an automatic thermostat, which is installed inside the refrigerator body.
Several light bulbs are fixed on top, inside the device, and egg trays are installed along the entire height. A homemade incubator from an old refrigerator is no worse than a factory one. With a little imagination over time, you can even provide for automatic rotation of the trays.
The next homemade project from an old refrigerator became a small but effective cellar. This homemade product is relevant for those who live in their own home. For these purposes, the refrigerator is completely buried in the ground, and a ventilation hole is provided on top of it.
It is imperative to provide a sufficiently wide passage to the cellar so that you can always use country preparations.
For those who are interested in beekeeping, you can make a small hive from an old refrigerator. In this case, the refrigerator compartment is covered with a board and arranged in such a way that the hive frames fit in it. Many beekeepers also paint refrigerators and customize them to suit their own needs.
Anyone who loves antiques will definitely adapt an old and unnecessary refrigerator into a cabinet. In this case, there is simply no limit to imagination! You can change the body of the refrigerator beyond recognition, paint it or cover it with adhesive tape.
A homemade refrigerator cabinet will be an excellent place to store a wide variety of things, and will even decorate the interior of your home. Refrigerator heat pump
Have you ever thought that you can make a heat pump from an old but working refrigerator? For these purposes, the refrigerator must have a working compressor, and a copper pipe will also be required to make a coil and a water heater with a volume of at least 100 liters.
It is possible to use a stainless steel tank as a heat pump condenser, inside of which a coil of copper tube is wound. For these purposes, you will have to cut the tank into several parts and then reconnect it. At the outlets from the coil, threads should be provided for connecting pipes from

What you need to assemble the installation
To assemble a compressor for inflating tires, you need to prepare the necessary materials. Including this:
- compressor from a freezing system or refrigerator;
- cable with plug for connecting equipment to the network;
- automobile air filters (2 pcs);
- oxygen supply hose (installed on the pipes);
- spiral hose for oxygen with removable adapters;
- device for inflating wheels (air gun)4
- wires and clamps.
You will also need tools, namely: pliers, a screwdriver, a knife.
The process of assembling a compressor unit for inflating car tires
Once the materials and tools are prepared, you can begin assembling the compressor. Let's look at this procedure step by step.
- The compressor installed in the refrigerator is equipped with a special starting relay, as well as a connected thermostat. When assembling the installation for pumping, these elements are not needed, so they should be disconnected in advance, not forgetting to mark the contacts, closing them on the start relay using a piece of wire (be sure to insulate them).
- Now you need to select an oxygen hose, focusing on the diameter of the outlet tube (pipe), install an air filter at the inlet to the compressor. One of the pipes intended for air intake can simply be cut with a knife, leaving the hole free. It is not necessary to use clamps when connecting elements. After all, this part of the installation works freely and is not subject to powerful pressure loads. The main thing is that all the elements fit tightly and do not scroll
- We proceed to attaching the air filter, which is installed at the outlet of the compressor. If necessary, you can shorten the copper pipes coming from the housing using wire cutters. This part of the structure is mounted only with clamps. After all, as practice has shown, even weak pressure is enough to tear off the hose at the most inopportune moment. The second exiting copper tube can be plugged using tape or tape.
- A spiral hose, which is usually used for compression work, is attached to the installed filter using an adapter. A special gun is installed on it, which allows you to open and shut off the air supply.
By doing this, you can assemble an effective device for inflating car tires. The power of the equipment depends on which compressor was chosen for the conversion of the installation.
Compressor for airbrush from fire extinguisher and refrigerator
Making your own small compressor for an airbrush is very simple.
For these purposes, you will need a small air compressor, as well as a container in which air under pressure will accumulate, in other words, a receiver. For this homemade product, the author used a compressor from a refrigerator as a compressor. As for the receiver, the OHP-10 fire extinguisher was perfect for these purposes, the volume of which, when measured, turned out to be 10.5 liters instead of the declared 8.5 liters; the fire extinguisher was obtained almost free of charge. The homemade product cost the author no more than 2,000 rubles. Materials and tools for homemade work: - OHP-10 fire extinguisher or other suitable one; — pressure switch PM5; — two moisture separator filters; — one fuel filter; — reinforced PVC hose (internal diameter 10 mm); - gearbox with pressure gauge; — a pressure gauge for measuring the pressure inside the receiver; — FUM tape; - pliers, wrenches and other tools.
Airbrush manufacturing process:
Step one. Preparing the fire extinguisher
The first step is to empty the fire extinguisher of its contents. This must be done in an open area. Now you get an empty cylinder; you need to screw it to the base. This process will not be difficult for anyone. All contents must be removed from the lid, including the fire extinguisher. As a result, there should be a cylinder and a lid.
Step two.
Homemade assembly You need to cut a 1/4 inch pipe thread in the cast iron lid. You need to wrap FUM tape around the wide thread of the cylinder for tightness, and also make a rubber gasket if the original one is lost or damaged. It can be made from a car camera. Well, then the cast iron lid is screwed on.
Then a 1/4 HP to 1/2 HP inch adapter is screwed into the hole in the cover. Then you need to screw on the 1/2-inch cross. Of course, all connections must be sealed using FUM tape.
You need to screw a pressure switch into the adapter with 1/2HP-1/4HP, and the adapter 1/2HP-1/2HP is also screwed into the side.
The author screws the tee on the side.
Subsequently, a reducer is screwed to the tee using a 1/2HP-1/4BP adapter; it has a 1/4HP thread.
On the other hand, again through the 1/2HP-1/4VN adapter, a pressure gauge is screwed on, it also has a 1/4HP thread. It is necessary to screw in a valve on the opposite side of the cylinder, with the help of which air will be released from the cylinder. The valve has a 1/2 HP thread.
A water separator filter needs to be connected to the gearbox; a 1/4 HP thread is used here. It is important to install the filter at the correct angle. The drain hole should be at the lowest point.
Then you need to make another filter line. On the side of the inlet hole there is a 1/2BP fitting connected through an adapter 1/2HP-1/4BP. It needs to be screwed onto the filter, which has a 1/4 HP thread. What should happen in the end can be seen in the photo.
You need to screw a 1/4HP-1/2HP adapter into the hole of the 1/4HP filter, and then screw a tee to it.
On one side the tee is plugged with a 1/2 HP plug, and on the opposite side a 1/2 HP fitting is screwed in. Step three.
The final stage of assembly Now you need to take the reinforced hose and screw it onto the fitting coming out of the fire extinguisher, which acts as a nozzle. The hose is secured with a clamp. On the other side, a fitting from the filter is inserted into the hose, and it is also secured with a clamp.
After this, the hose is again connected to the filter and connected to the compressor tube. Everything is tightened with clamps.
At the final stage, a similar fitting must be screwed into the outlet hole of the 1/4BP filter. A silicone tube fits perfectly onto it and doesn’t even need to be secured with a clamp. Well, the other end is connected directly to the airbrush.
Due to the fact that the pressure behind the reducer is small, compared with the receiver, the tube can withstand it without any problems.
The compressor requires maintenance; its oil needs to be changed. To do this, you can find three tubes on the compressor, one of them will be sealed, it is through it that the oil is changed. The tube can either be drilled or cut with pliers like the author. Next, you need to drain the oil from the compressor; it will be about 300-350 grams. You can fill the place with 10W40 automobile oil. This oil ideally protects compressor elements from wear and does not absorb moisture. Source
