DIY compressor installation in the garage. Modernization of the auto compressor

Homemade compressor (60 photos and detailed description of manufacturing)

Made a home-made air compressor: a detailed photo report on the manufacture of a compressor based on the ZIL-130 head.

I needed a compressor for a home workshop., somewhere, something to blow, pump up the wheels or dye what kind of trifle.

Initially, I wanted to buy a finished (Chinese) solution in the budget up to 10 thousand. r, but after searching for information on compressors, I realized that everything is sad there. You need 15 with about the money to buy this miracle equipment and then not regret it, about the money spent.

As a result, he matured to repeat the feat of many and contact the legend of the domestic Soviet auto industry called ZIL 130 In addition, he studied for auto mechanic in trucks in a techipper, then this ZIL-130 car and the MTZ-82 tractor completely studied, to the bolt of everything. Three years, all academic period!

What can I say in favor of this compressor head of the good The most important is its plus.She is not “killed”! There are almost everything spare parts and are not expensive enough. You can always find details according to the article and order. Her lubricant system is under pressure from the engine oil line, the same. The compressor head is constantly working as soon as the engine starts. After reaching 7.5Atm, in the brake system, the head passes into idle mode and begins to pump air from one cylinder to another. Operating temperature 90-100C approximately. It was at this temperature that our engineers designed it. Something like that after reading a bunch of forums and looking at the “all” vidos on the YouTube, I realized that there are different opinions on these compressors. Personally, I wanted to do, the easier, the better. Therefore, it was decided to make the lubricant system with “scoops”, like everyone’s favorite co-7B legend and a cooling system with natural circulation in the form of an expansion tank and that’s all! To begin with, I searched for a long time for a used head on Avito and Yulia As a result, I found it for 1500r. The seller said that she, too, once worked as a garage compressor, but not long Her condition was just horror. But there were no more options, I had to buy. As a result, I cleaned the cord with a brush on a corner grinder and the view has already become better.

Inside the blackness, as it turned out later, it overheated and the butter stuck to the walls.

The condition inside, terrible I had to soak the whole thing for days in the solvent and gasoline. All the rings on the pistons lay down. To dismantle them, I had to pick up and knock them out with a hammer At the same time, the rings broke in small pieces. No solvents unwinded them. After the head and plane of the cylinder turned out.

Oddly enough, the cylinders were without bullying. Hong is even visible (there are no photos). Piston in the cylinder VMT practically without backlash. The piston itself was also quite in good condition. The crankshafts without bullying, but the bearings were already with the backlash. Therefore, new inserts, bearings, a set of gaskets, a set of rings, studs and a set of intake and graduation valves were bought.disgusting quality. The lubricant system decided to do, as I already wrote above.”Scoops”. To do this, you need to drill the block itself under the saapun, then two holes in the connecting rod and the third in the bugle under the scoop itself.

In order for these scoops to work, you need to boil an oil tray. As it turned out, I didn’t take pictures. Everything is simple there. Four corners on the rib and below the plate welded. At the same time there is an expert for the site.

The engine will be installed 3kW 2900 on a three.phase into a single.phase network. The site decided to make one for the engine and head. She will also be removable from the Resver.

The cylinder, like all of Propanovo on 50l with wheels.

Further, the drain bolt was welded to the bottom of the condensation cylinder and two nipples from a half.inch pipe for a pressure gauge and a press startup. The wheels changed a little to others with a wide tread))) the third leg with a rubber gasket is also. From vibration, all these rubber products help. Well, for painting.

Now about the cost.

If someone decides to build a compressor based on ZIL, KAMAZ and other heads, it must first calculate about its cost. On YouTube in the videos, everything is simple and cheap ZIL, the cylinder and ready))) In fact, everything is not at all like that.

  • one. Classic Bull.Propan 500r on Avitoyul. (I was in the tan)
  • 2. Wheels. 300r approximately (acquaintances fitted)
  • 3. Corner 50 2 meters, pipe 1/2 2 meters per handle approximately 200r
  • four. Compressor ZIL 130. 1500 rub the lower market on Avito and you need to go for it gasoline 500r
  • 5. Rimcoplet for this head (rings, bearings, gaskets, inserts, valves) 1000r
  • 6.Electric motor 2500tr Avito (I was given for free) again I need to go somewhere after him.
  • 7. Electrician if you have 380V, then this is the easiest and cheapest option. Need a 380 press.sett and a magnetic starter. In my case, to connect to 220V you need 3 conders for 1500r, 500r relay, magnetic starters of 1000r, Pressure on Ali.1000r

I won’t even count the rest of the little things. Valve, fittings, American. I had it all. all this is connected with my work))) If you buy all this, then it can go out another 1000-1500r. In the end. I approximately cost 7tr for money and I still need to order a press. Well, such work is not a burden to me, but in joy! The conclusion will rather be like this If the material on the compressor is generally a goglyak and nothing is better, then it’s better not to bother immediately, but to dig up more money and buy a normal belt compressor immediately! Guys, something like that everything is without embellishment! Good luck and so far! Author of the Homemade: Reanimator33. G. Orekhovo-Zuevo.

A simple version of the aggregate from a fire extinguisher/gas cylinder

Make a compressor with your own hands using a storage container for the air of a fire extinguisher or a gas cylinder as a cerebral. For example, the compressor block itself, if you need to make a powerful unit, can be taken from the Zilov compressor. But first it needs to be modified a little.

  • Drill one hole in the compressor wall through which oil will be poured into the crankcase. Which side do you do from, it does not matter. The main thing is that it is located below the crankshaft axis by approximately 10 mm. In this hole, the M8 thread is cut under the cork.
  • To the cover covering the rear bearing, the fitting is connected. An oil.resistant hose is put on it, which will be connected to the lubricant system in the form of an expansion tank (you can take a tank for brake fluid from the car) installed at the cylinder level.

2 holes should be drilled in each connecting rod (assembled, along with liners) and 1 hole in each lid of connecting rods.

When the unit was operating, the oil in the crankcase will come through these holes to the liners and reduce friction between them and the crankshaft.

Next, a receiver and a strapping with automation are connected to the compressor. How to make it was considered in the previous paragraph.

If you take a fire extinguisher for the receiver, then you first need to extract all the extra details from it, leaving only the capacity and cover itself.

In a cast.iron cover, cut the thread ¼ inch. Also, under the cast-iron cover, it is necessary to lay a rubber gasket if it was not there, and tighten the lid, applying a fum tone to seal the thread.

Next, the adapter from 1/4rd to 1/2rd should be screwed into the cover and install the cross.

Actions to connect all the elements of the binding were described at the beginning of the article. But, since this unit is made of compressor ZIL 130, and is more powerful than previously considered, you will need to install a safety (emergency) valve. He will drop excess pressure if for any reason automation does not work.

You can also make a compressor from a gas cylinder. But first, you need to release the gas from the cylinder, and then twist the valve. Next, you need to completely fill the balloon with water to remove gas residues. The cylinder should be washed with water several times and, if possible, dried. Usually a gas burner is installed under the cylinder and all moisture is evaporated from the container.

Futorka is screwed into the hole where the valve was placed, and the cross, to which automation is attached to it, is screwed into it. In the lower part of the cylinder, it is necessary to drill a hole and weld to it a fitting for draining condensate. You can install a regular tap tap on the fitting.

To fix the engine receiver and the compressor unit, a frame of a metal corner is made. Previously, fasteners are welded to the cylinder. The frame will be attached to them (see. a photo. below).

Important! The engine for this unit should have a power of about kW.

It is also possible to make a pump yourself from a chainsaw, which cannot be repaired. The device is made from the engine, that is, from the piston block: the output hose is connected through the check valve instead of the spark plug, and the hole for exhaust gases is blocked. To rotate the cranksal, you can use either an electric motor or an ordinary electric drill.

A compressor from the refrigerator

The air compressor made of the refrigerator, more precisely, from its unit, is the most silent. But you should know that such a device is not highly performance. With it, you can only pump up the car tires or work as an airbrush. For the normal operation of various pneumatic tools (electric screwdriver, grinder, spray gun, etc.D.) the performance of this unit is not enough, even if you connect a large volume receiver to it. Although on the Internet you can find structures consisting of two or three compressors connected sequentially, connected to a large receiver.

So, the unit removed from the refrigerator has a launch relay with a network cord. 3 copper tubes also come out of the apparatus. Two of them are intended for the entrance and output of air, and the third (sealed) for filling the oil. If you turn on the device for a short time, you can determine which of the two tubes the air sucks, and from which it is blown out.

The following figure shows how to assemble the entire structure consisting of an unit, receiver and pressure regulator with a pressure gauge.

Advice! Instead of the output filter, which sometimes breaks from high pressure, it is better to install a moisture separator. Its presence is mandatory if the device is used for painting.

An air filter is installed on the input tube to exclude dust from the unit entering the unit. To automate the air pumping process, you can install automation in the form of a press start.

Alternative to a professional device (compressor from the refrigerator)

Homemade compressor devices last much longer than the time presented even in comparison with the installations of domestic and foreign production.

This is quite natural, because creating it with our own hands, we do everything for ourselves at the highest level. Therefore, the people even thought out how to create a compressor from the refrigerator, which will be at the level with the installations of popular companies.

But to create it, you should stock up on such components as a manometer, relay, rubber adapters, oil.controling, fuel filters, gearbox, motor, switch, hose, clamps, brass tubes, but also trifles. nuts, paint, wheels from furniture.

Creation of the mechanism itself

Simplify the entire procedure can buy a compressor from the old refrigerator of the Soviet era. This will not pull too much on the budget, while there is already a starting compressor relay.

Foreign competitors are inferior to this model, because they are not able to develop such high pressure. But the Soviet ones cope with such a task.

After eliminating the writ of execution, it is advisable to clean the compressor from the layers of rust. To avoid in the future, the oxidation process should use the rust converter.

It turns out that the working body of the motor is ready for the painting process.

Scheme of the installation

The preparatory process is completed, now you can change the oil. Since the refrigerator is old and it is unlikely that it passed constant, it is worth updating this moment.

compressor, installation, garage, auto

Since the system has always been far from external influences, no service was justified there. For this procedure, expensive oil is not required, and semi.synthetic.

over, it is no worse in the presented characteristics of any oil for the compressor and has many additives used with benefit.

Inspecting the compressor, you will find 3 tubes, one of them is already sealed, but the rest are free. Open ones are used for the input and output of air. To understand how the air will circulate, it is worth connecting the compressor power.

Write down for yourself which of the holes draws in the air, and which produces it. But the sealed tube must be opened, it will serve as a hole for replacing the oil.

Nadfil is necessary for the carrying out of the pipe, and be sure to make sure that the chips do not get into the compressor. To determine how much oil is already there, we drain it into the container. With the subsequent replacement, you will already know how much it will have to pour in.

Then we take the spitz and pour semi.synthetics, but this time calculate that the volume should be twice as much as they have already merged. When the container is filled with oil, it is worth drowning out the engine lubrication system, for this a screw is used, which is pre.designed by the FUM tape and is placed simply in the tube.

Do not be alarmed if the oil drops will appear from the output air tube. This situation is not so difficult to resolve, find the oil detector for a home.made installation.

Preliminary work is over, only now you can start direct assembly of the installation. And they begin with strengthening the engine, it is best to choose a wooden base for this and in such a position so that it is on the frame.

It is worth noting that this part is very sensitive to the position, so follow the instructions on the top cover where the arrow is drawn. Accuracy is important in this matter, because the correctness of the change of modes depends directly on the correct installation.

Where compressed air is placed?

The cylinder capable of withstanding high pressure is a container from a fire extinguisher. At the same time, they have high strength and can be used as attachments.

If you take as a basis the OU-10 fire extinguisher, which holds 10 liters, then it is worth counting on a pressure of B15 MPa. We unscrew the locking device, instead of which we install the adapter. If you have detected traces of rust, then these places should be mandatory processed by a rust converter.

It is not difficult to remove it outwardly, but it is more difficult to conduct internal cleaning. But the easiest way to pour the converter itself and shake well so that all the walls are soaked in.

When the cleaning is carried out, the water crossbar is screwed and we can assume that we have already prepared two working details of the home.made compressor design.

Carrying out the installation of parts

It was previously stipulated that a wooden board is suitable for fixing the engine and the fire extinguisher case, it is also easier to store working details.

In terms of engine mounting, threaded studs and washers will serve, just think in advance about making holes. To fix the receiver in vertically, plywood is required.

It makes a seizure under the cylinder, the second and third are fixed to the main board using self.tapping screws and holds the receiver. To give the design of maneuverability, screw the wheels from furniture to the base.

So that the dust is not in the system, you should think over its protection. the use of a filter for rough fuel purification can be considered an excellent option. With it, the air intake function will be easily performed.

Since the openings with the input of compressor equipment are low indicators of pressure, it will not have to strengthen it.

Having created the input filter for installation work with the compressor, do not forget to install the oil detector at the end to avoid drops of water in the future. Since the output pressure indicators are high, car clamps will be needed.

The oil.controling filter is attached to the gearbox input and the exit of the supercharger by pressure. To control the cylinder pressure, you should screw the pressure gauge on the right side, where the exit is located on the opposite side.

Binding components of the compressor

When it was decided which compressor to choose and reverse, it is worthwhile to deal with the issue of their unification. At the same moment, it is worth determining how the air will go to the airbrush. The node that is mounted to the receiver is responsible for the distribution of air.

The main thing is that these components are compatible with each other. For disconnecting and turning on the compressor, the pressure relay is responsible. RDM-5, although it is used for water supply systems, this is ideal for our case-for the relay.

The bottom line is that the element for connecting is suitable for an external inch thread. To find out what pressure in the receiver, you need to use the pressure gauge and first think about the size that is suitable for connecting. We supply pressure in the air preparation unit and adjust it within 10 atmospheres, at this stage it is necessary to attach the oil separator filter.

The pressure gauge allows you to check the pressure, and the filter allows you to prevent the oil particles from the receiver. Turns, tees and even fittings are the following components that will have to be prepared for installation. To understand the exact number, you need to think over the diagram, select an inch as a size.

After resolving the issue with adapters, it is important to think over the moment of installation of the structure, most often for this use the boots wood-bearing plate. The design of your station should be maneuverable, because it will have to be moved around the workshop in order to simplify your work, it is worth attaching to it legs-rollers.

You don’t have to invent for a long time, just visit the furniture, where there are a lot of such wheels from furniture. To save space in your workshop, you can build a two.story structure. But here it is better to stock up on large bolts to fix the structure. To simplify preparations for this stage, make a list of mandatory components.

Advanced convenient compressor with your own hands

How to make a compressor that will not be inferior to the best and foreign counterparts? You will need the following details:

  • ordinary pressure gauge;
  • gearbox, be sure to choose a filter gearbox to eliminate oil and moisture from the receiver;
  • any relay for adjusting pressure indicators;
  • fuel filter (for gasoline, not for diesel);
  • Connecting coupling for four outputs of the water supply (inner diameter 3/4);
  • You will need adapters in diameter for hermetic compounds of parts;
  • large car clamps;
  • receiver;
  • motor oil. you need a viscosity of at least 10W40, metal paint and additive from rust;
  • electric toothbler;
  • oil hose;
  • A piece of thick board. this will be the basis of the compressor;
  • syringe;
  • metiz for fasteners;
  • silicone sealant and fumlat;
  • furniture wheels;
  • diesel engine filter.

Half of components can be found in any garage.

We select the engine for the compressor

A good engine for our compressor is spare parts from the old Soviet refrigerator, it already has a launch relay, this is very convenient, as it regulates the number of atmospheres in the receiver. You need a engine from the old unit (Dnieper, Donbass, Oka), imported models give less pressure in the atmospheres.

  • The compressor needs to be cleaned, rusted, greased with the internal parts and paint on the outside. There are three exits on such a compressor. we find out where the feed is, and where the air jet is released, we mark with a cross;
  • One tube in old models is sealed, it must be carefully opened, it will be a hole for the topping of the oil into the compressor.

Important. So that when sawing off the tip, the chips do not get into the compressor.

  • Pour the old waste oil and pour the same amount of semi.synthetic oil, it is convenient to fill the oil into the compressor with a syringe of 2 ml;
  • Put a plug from the screw and seal with fumlet;
  • We install an oil filter on the output tube;
  • We fasten the compressor, a cylinder with compressed air and the launch relay to the board.

For compressed air, it is convenient to use a tank from an old fire extinguisher by 10 liters, no longer need. Such a cylinder withstands pressure up to 15 MPa.

Necessary materials and tools

The main element of the scheme of a home.made compressor is an electric motor. In addition to him, we need:

  • 2 pulleys of different diameters;
  • pressure regulator;
  • pressure switch;
  • replaced air filter;
  • moisture detector;
  • belt;
  • bolts, clamps;
  • hoses;
  • receiver;
  • air pistol;
  • expansion tank;
  • radiator;
  • capacitors;
  • compressor.

It is better to make a stanch for a compressor from a gutinax. A plate of 50 × 30 cm thick 3 cm thick is suitable. The choice is justified. The metal will weight the structure, but at the same time it is durable, light, can be operated in a large temperature range. And also has good electrical insulation properties. The assembly of the bed needs 4 furniture wheels, 16 bolts.

For work, power tools (corner grinding, drill), screwdrivers, keys, drill will also be required to work.

The process of work

Homemade garage compressor consists of several nodes. Each has its own function. The assembly is carried out sequentially. Start with the bed, since all the details will be attached to it.

Assembly of the bed

Draw a rectangle of the desired size on a sheet of gutinax (50 × 30 cm). Then, applying the wheel, outline the fastening points in every corner. corner grinder cut the workpiece of the bed. Drill holes and fasten on the wheel bolts.

Installation of an electric motor and mechanical part

On the right edge of the bed, an electric motor is installed, tightly attached to the bolts. The compressor is placed to the left of it. The pulley taken from the car generator is welded to the sleeve.

Air assembly

The airfield scheme includes an air filter that stands on the air fence. To install it, use a rubber coupling with a threaded connection. It is replaced and easily unscrewed.

Receiver, pressure regulator, moisture detector, pressure relay and air pistol are connected by hoses. Inclusion in the pressure regulator circuit provides an automatic compressor operating mode. Pressure can be set from 0 to 10 atmospheres.

Assembly of the cooling unit

During prolonged operation, compressor overheating is possible. To exclude it, a cooling unit has been added to the circuit. The main element is the radiator. It is installed on the engine and connected by a pipe with an expansion tank.

Such a solution is multifunctional. Engine cooling and blowing radiator occurs. The necessary movement of the liquid is provided by an electric pump (pump), which is mounted in an expansion tank. high pressure compressor

The procedure for creating a compressor for generating pressure with your own hands is quite simple, it can be carried out in your own garage. instructions are as follows:

  • To begin with, there is a demanding gas cylinder from which the valve is removed and the remaining gas is merged.
  • After that, the motor is removed from the old air conditioner or other suitable device.
  • The valve is twisted.
  • The gas cylinder is filled with water.
  • The drill is used to obtain holes that are suitable for fixing the valve and gearbox.
  • The protruding elements must be cut off. Due to this, the use of the compressor is greatly simplified.
  • The new update is welded to simplify the connection of other equipment.
  • Experts recommend making a special element that is required to fix the wheels. They greatly simplify the transportation of the compressor from the gas cylinder through the territory.
  • The next step provides for the creation of a shelf on which the engine will be installed. When creating a shelf, it is worth considering the moment that it should have increased rigidity. Otherwise, during operation, vibration will occur, due to which the operational qualities of the installation are deteriorated.
  • You can make the device more attractive and extend its service life by coating the surface with paintwork material.
  • Electricity and hoses are connected. This points should be paid to special attention, since improper connection of electrical wiring can cause a large number of different problems.

This version can be called quite simple, as well as inexpensive. It is suitable for solving most problems in a home workshop. Of course, the design does not have characteristics that are characteristic of industrial options.

Installation of the required pressure

A rather large number of problems arise with the installation of the required pressure. This is due to the fact that it can vary in a large range depending on the following points:

  • Length of the highway. With an increase in the length of the highway at the output, the indicator is significantly reduced.
  • The capacity of the hose. This indicator also affects the pressure.
  • Type and power of the installed motor. Very widespread devices that are powered by 220 in network.

The control of the parameter under consideration is carried out at the expense of the pressure gauge, which is built into the gearbox. When choosing a pressure gauge, attention is paid to his accuracy and many other moments.

We do it with our own hands

After all the necessary nodes and tools are collected, you can make a compressor from the refrigerator.

In the camera tested for tightness, it is necessary to make a hole. To do this, you need to use an awl. A chamber nipple will be installed in the resulting hole. Its task is to remove compressed air from the chamber.

An additional fitting is installed by gluing, this will require the use of the repair kit. After that, the fitting must be installed on the spray gun. To perform the check, leaving the air flow, it is necessary to remove the nipple. Yes, by the way, the native nipple should be left in place, it will play the role of the valve, and hold excessive pressure that arises during the compressor operation. To determine the pressure level, you can try to apply a layer of paint to the prepared surface. If it goes to bed evenly, then the installation is working in normal mode. To check the pressure level, you can use a pressure gauge. Its level should be stable. It is not difficult to develop a compressor design and assemble it, but the fact that the use of such a device will greatly facilitate the painting of the car, etc.

Semi.professional air supercharger

To create a semi.professional installation of compressed air, a larger number of components and tools will be required. In particular, instead of a rubber chamber, it is advisable to use a cylinder for propane. In addition to him, it will be required:

  • Reinforcement for fastening metal sleeves.
  • Metal plates, the width of which should be 30-40 mm, and the thickness of 3-4 mm.
  • Two wheels with a platform for its attachment to the receiver.
  • Compressor.
  • Metiza.
  • Armature for tuning pressure.
  • Welding apparatus. inverter.
  • Electric screwdriver.
  • Metal cutters.
  • Grinding with abrasive circles.
  • Metal brush;
  • Divorce keys, pliers.

Working mechanism

To assemble a semi.professional air injection, you can use a compressor from a non.working refrigerator made in the USSR. These refrigerators are superior to imported analogues in that they are able to produce higher air pressure.

Air capacity

As a container for compressed air, you can use propane cylinders and old fire extinguishers. This is due to the fact that these containers are able to withstand a rather high pressure, and have a large margin of strength.

As an example, take a supercharger made from the fire extinguisher OU 10. Its volume is 10 liters. Such a receiver can safely withstand the working pressure up to 15 atm. The starting device is removed from it and the adapter is installed.

Of course, if traces of corrosion are detected, they must be removed using the converter. This business is quite simple, the outer surface can simply be treated with a moistened rag, and for cleaning inside you will have to pour a certain amount of liquid and shake it for a rather long time.

After the container is cleaned, you can start installing a tapesty cross. After that, we can assume that two parts of the future installation are ready.

Installation of details

To simplify the assembly process, all details are best collected in one place. So, for the installation of the discharge installation and air capacity, it is permissible to use a thick board.

For attaching nodes, you can use hairpins, previously equipped with washers and nuts. The receiver is installed in vertical condition. To do this, you can use three sheets of plywood. In this case, in some of them, a hole is performed the size of the diameter of the receiver. The remaining sheets are fixed to the base board using screws.

compressor, installation, garage, auto

By the way, it will not hurt to prepare a place for the receiver. To ensure the mobility of a home.made compressor, the wheels are screwed to the base of the board.

After the work done, it is necessary to provide compresses from dust. To do this, you can use the rude fuel cleaning filter installed on internal combustion engines. This detail will play the role of the air intake. For the manufacture of this system, you will have to use a rubber sleeve and the input tube.

Here we must recall that the input pressure is quite low, and therefore it makes no sense to strengthen the connection with a clamp.

At the end of the listed operations, the master get a finished air fence system equipped with a filter. But we must not forget about the installation of the oil separator. Its task is to remove moisture and oil particles. The fuel system filter will be used in this node. And therefore, car clamps must be used to install these nodes.

This filter should be connected to the compressor entrance. Its task is to ensure the denouement of the receiver and exit from the supercharger. In other words, on the one hand, the crosses set the way out, and on the other manometer that controls the pressure in the receiver. In the same node, it is necessary to provide a place for installing an adjusting relay. Practice shows that for this purpose the optimal solution will be the use of the standard product of the RM5 brand or its analogues. The task of this product is to turn off the engine upon reaching the maximum pressure in the container and turning it on, when falling to the permissible minimum.

Adjust the pressure

The required pressure is regulated using two springs installed in the RM5 device. The large spring is designed to install the minimum pressure level, and small to install the maximum. In this way, the boundaries of turning on/off the compressor engine from the refrigerator are installed.

Undoubtedly, all electrical connections must be insulated and seized.


After assembling a home.made installation, you can proceed to its tests. That is, an air hose with an connected spray gun is connected to the receiver output, with a paint in it. Then, with thorough observance of the technology, perform a layer of paint to the prepared surface. That is, it should be cleaned of a layer of old coating and degree. If, after applying the paint layer, there are no stumps, matte spots, non.coloring, then the installation works as usual and it can be operated when performing different works.

Connection of the nodes

The segment of the hose with the fuel filter mounted on it must be connected to the input hole of the compressor. The purified air will come here from the external environment.

The output of the compressor must be tied with a hose with the inlet hole of the receiver, using reliable clamps, since the pressure indicators here will be significant. A long hose is attached to the receiver on the outgoing fittings that supplies a stream of air to the work area.

Comparison of a purchased and amateur compressor

Do I need to take up the difficult work of assembling the compressor? Compare the characteristics of the professional and homemade option:

The factory model is equipped with an accurate pressure control system, manometer, filters. When constructing the unit on your own, you can assemble a full package of necessary components and install them in their places without prejudice to quality.


A compressor from an old supercharger from the refrigerator works noticeably quieter than purchased models.

Using the details and units of the used, as well as your work, you can save a considerable amount of money, presenting, in addition, a second life for several efficient things, for which nature will say thank you to you.

If the power of a home-made compressor will not be enough for you in the future, you can always improve the design by replacing, for example, a receiver from a fire extinguisher with a cylinder from propane-button or generally for a gas tank of a used gas.

Checking performance

Before applying the device, it should be checked. This is due to the fact that the mechanism works on electricity, which means there is a high probability of electric shock. Considering the features of checking such devices, we note the following points:

  • The state of all electrical connections is checked. Low.quality connection leads to a short circuit or electric shock.
  • Attention is paid to the tightness of all tubes. The principle of operation of the compressor is to create high pressure. Checking the tightness of the tubes is quite difficult, as a rule, serious defects appear almost immediately.
  • When using a compressor for painting, you must first use it to work with non.exposure elements. This is due to the fact that the hit of minor particles can lead to a significant decrease in the quality of the surface.

You can use the compressor only after checking the device, since errors made can reduce efficiency or bring into unsuitability of the entire structure.

Car chamber compressor

Compressors from the car chamber are quite widespread. This can be associated with a low cost of the resulting device. Among the features of this option, we note the following points:

  • You can assemble a mechanism in a home workshop. This will take a relatively small amount of time, and a standard set of tools is required to work.
  • The cost of the final product is relatively small. This is due to the fact that almost everything you need can be found in the garage.
  • Can be used to pump up tires or for painting work. Due to this, the scope of the device is expanded significantly.
  • Subject to assembly recommendations, you can provide a long service life.

Today compressors are found in almost every garage. In order to save on their purchase, you can collect a home.made construction.

Note that to make the choice of the most suitable home.made design based on the task. An example is the equipment of a paint workshop designed for a long job. For pumping tires, a less functional compressor is suitable, which is easier in manufacture and will cost much cheaper.
