Hello dear friends! Today we have a very interesting topic. Especially for those who prefer to wash their car with their own hands or think that the current prices for a car wash are too high. That is, it is going to switch from professional to manual washes. Therefore, the topic of our conversation is a foam generator.

But not GPSS, which is used to extinguish fires by feeding foam. And not generators for foam concrete. While some might be interested in renting them, it’s not about them.

We are talking about a special high pressure device that is used for. A kind of garden tool that allows you to wash your own car on the territory of a private house or even in the courtyard of a high-rise building (who is not afraid of neighbors or other threats).

Of course, the job can be done with a conventional low pressure sprayer. However, a high quality result cannot be obtained from a sprayer. But the foams create a homogeneous and finely dispersed foam. Due to it, an excellent effect is achieved. I use it myself, because I know what I'm talking about.

Features of the device

It is not so important whether you buy an Italian foam generator or order from China, structurally they all look about the same.

The structure includes:

• pistol;
• mixer;
• balloon.

A special nozzle as well as a foaming tablet ensures that this mixture is delivered under high pressure. As a result, the machine quickly becomes covered with a layer that cleans away the dirt.

Such washing cannot be called completely non-contact. If you need a result, you will also have to work with sponges or brushes.

An important characteristic, on which the work and the best indicator of efficiency depend, is the volume of the tank. Usually they are made for 25-100 liters. The compressed air supplied from the cylinder must have a pressure of 5-6 bar. At the outlet, the manual foam generator has a special regulator. It allows you to control the pressure using a built-in pressure gauge.

Sprayer or generator?

This is where a very important point arises. If you need a mini-washer, I advise you to choose a foam generator. Although many sellers for car wash offer to buy a spray. Some even pass off a conventional sprayer as a supposedly high-performance foam generator.

In some cases, a universal sprayer can do quite well. But it is inferior to a penny because it is not able to create the same persistent foam. At the exit, you get a conventional emulsion, the efficiency of which is much lower.

Therefore, I will teach you to distinguish sprayers from generators.

• the sprayer circuit does not provide for the presence of a regulator to control the quality of the mixture;
• in the sprayer, the outlet nozzle has a larger diameter than that of the foam.

These distinctive characteristics are enough to make the right purchase.

Speaking specifically about manufacturers, you should pay attention to the following brands:

• Karcher;
• Monsoon;
• Calm (Stihl);
• Huter (Hooter);
• Bosch;
• Elitech;
• Procar;
• Idrobase;
• Interskol;
• Champion;
• Patriot.

Go to Aliexpress, read reviews, explore different stores. The Internet works 24 hours a day, so you can always find out information about a particular model.

How does a foam generator work

Now let's study the principle of operation of such a device. What is he like? The work is carried out on the basis of fairly understandable processes.

In short, due to compressed air, a special shampoo passes through the foaming agent and a finished product is obtained, that is, foam. The education process is conventionally divided into two stages.

• Primary foam. A jet of water under the action of high pressure exits through the nozzle and mixes with the shampoo. In parallel, air is added to the mixture, supplied through special holes. But this foam does not have the desired characteristics, therefore it will not be suitable for washing a car.
• Finished foam. The so-called pill plays the main role here. The mixture we got in the first step passes through the tablet at high speed. This is a small device that provides a foam mass with the desired characteristics. The foaming tablet is made from corrosion resistant wire. They have different cell sizes. It is important to obtain a high expansion foam. This directly affects the quality of the washing machine.

At the exit, we get a stream of foam, which is easily applied with a hose to the car, and then washed off with water.

Advantages and disadvantages

Such a high pressure washer has important advantages:

• liquid constituents are converted into foam without loss;
• at the outlet, a stable mixture with excellent detergent properties is created;
• foam consumption and parameters can be adjusted;
• one charge of a 50 liter bottle allows you to wash from 10 to 15 cars.

But there are also a couple of downsides:

• you will have to constantly refill the cylinder with compressed air;
• you need to install a compressor.

Having a good sink at your disposal, using a special adapter, you can combine them into a common appliance. An excellent solution for those who have already acquired a car wash and want to improve the efficiency of their car wash equipment.

Someone even creates a homemade apparatus from a fire extinguisher or other improvised means. There are even a number of special videos where everything is clearly shown. But I would not recommend doing this kind of thing. If you want a foam dispenser for yourself and a really high-quality car wash, take the money and buy yourself a good generator, even if it is Chinese.

Refinement is another matter. When buying a household or professional foam pen, many note that some parts are not efficient enough.

A little bit about the revision

How can I make my foam maker even better? Here we are talking about increasing productivity, that is, increasing the amount of foam created.

No complex repairs are required. And you don't have to open the generator drawing. The essence of the refinement is to make the nozzle work better.

I note that many foams have problems with mixing components due to the imperfection of the standard nozzle. Water is supplied under low pressure, so although the shampoo enters the mixture, it does not fully mix. There are models with a too narrow hole through which shampoo is fed. The water simply does not allow the detergent to push in there.

There are two methods that can be used to improve the lack of factory pennies.

The cost of such a revision can be zero if the necessary materials are available.

About shampoos

Where to buy shampoos? In any automotive chemistry store. But it is very important to understand how to use special chemistry.

Cities such as Moscow, Yekaterinburg, St. Petersburg and many others offer a huge range of special active foam. To be more precise, the concentrate is being sold.

Try to choose quality mixes that are popular. Never use concentrates with a pH value over 12. More aggressive mixtures can corrode paintwork, chrome parts, rubber seals, etc.

It is also impossible that the shampoo contains a component called sodium hydroxide or just caustic soda. It is abused by manufacturers because it effectively removes dirt and is cheap. But at the same time, it causes enormous damage to the paintwork.

The idea of ​​a non-contact car wash is based on minimizing the impact on the paintwork by regularly cleaning the body panels. In practice, it is the car wash foam generator that allows you to perform this kind of car care.

Purpose and principle of operation of a finely dispersed generator

During operation, the foam generator for washing, due to the high pressure inside the working cylinder, creates foam, which is applied to the body panels to clean them. The composition successfully fights the most stubborn dirt. In this case, the mechanical impact is minimal.

The use of an active foam composition allows for complex cleaning from contamination:

dust and dirt;

persistent organic compounds;

microflora.

The main obstacle for the individual use of the current type of construction is the high price of a professional product. An expensive car does not justify the costs if it is periodically used to wash one car. Therefore, home-made installations for contactless washing are popular.

WATCH THE VIDEO

Structurally, a foam concentrate for a car wash is similar to any overpressure installation - from a garden sprayer to a bottle for pumping liquefied gas. The design of the device includes the following elements:

High pressure cylinder.

Foaming agent for substances.

Sprayer that provides delivery and atomization fineness.

The connecting hoses are long enough.

Taking into account the volume of the injection tank, it should be possible to transport the equipment, taking into account the total weight.

The foam is generated from a special foam tablet. This element is a fine-mesh, corrosion-resistant wire mesh. After the passage of the tablet, a liquid fraction with a high specific gravity is formed.

Manufacturing a functional and safe structure

Before the start of manufacturing, it is required to realize that high pressure will become the main hazardous factor during the operation of the device. When assembling a foam generator with your own hands, you should not save on installation elements.

Requirements for the capacity of the foam generator

It is more convenient to make a homemade foam generator from a container of 25 liters or more. This will be enough for a one-time wash. The main requirement for the cylinder will be the manufacture of stainless steel, or it is allowed to use ordinary steel, subject to treatment with an anti-corrosion compound. Durable plastic is also actively used.

Additional conditions will be:

• pressure resistance up to 6 bar;

the presence of a measuring ruler to control the filling level of the container;

the presence of threaded holes for the spray, pressure gauge.

Sprayer requirements

The structure includes a foam sprayer. This element must be different from a similar sprayer device. Such equipment is designed to obtain an emulsion that is inferior in purification efficiency.

A suitable nozzle for a car wash in a steam generator compares favorably with a simpler sample:

• has a finer spray;

allows you to adjust the degree of feed;

saves detergent solution.

High pressure cleaning solution

It is impossible to create a foam generator with your own hands for a car wash without a pressure source. For normal operation of the equipment, the generated pressure must be in the range from 4 to 6 atmospheres.

When completing the installation, the compressor will be the most expensive of the elements. If you purchase a second-hand sample, you should discard the copy with signs of wear. In this case, a compact unit for pumping wheels will not cope with the work either.

We assemble a foam generator for washing with our own hands

We make installation drawings

Start assembly work only after sketching a perspective design on the diagram, which shows the device for a foam generator for a car wash. This will allow you not to miss the following positions:

• determine the sequence of assembly operations;

generate a complete list of parts and materials for assembly;

prepare the necessary tool.

The obligatory tool kit includes:

set of wrenches;

grinder;

pliers;

• flat and Phillips screwdrivers;

Diagram of a foam generator from a fire extinguisher

Used metal containers are ideal for making a foam generator for a compressor. When selecting a container from a fire extinguisher, give preference to a cylinder with a large diameter to avoid falling.

The work is carried out according to the following algorithm:

1. Prepare a standard hole for pouring the mixture.

New holes will be needed at the bottom and center.

Tubes with fittings of the required size are welded into the holes to build pressure and drain the liquid to the gun.

Sprayer version

The option to make a foam generator for washing with your own hands from a sprayer is the most preferable. This is due to the closeness of performance in comparison with the factory product. You will need to disassemble the foam generator by dismantling the valve and the fastening nipple. There must be two mounting holes available prior to assembly.

Subsequent work is carried out in accordance with the algorithm:

We screw the squeegees into the holes and fix them with nuts. Installation of gaskets is required.

We install a fitting with a non-return valve on one of the squeegees for pumping air.

We fix a special tank with a tablet on the second squeegee.

A DIY foam generator created from a garden sprayer will work correctly only if air is supplied from the bottom of the tank. A normally functioning device with an operating pressure of at least 4 bar consumes only 40 grams of shampoo.

How to make your device better

The practice of building home-made foam generators allows us to highlight all the new directions of their modernization. And if the basic drawings remain the same, then individual elements are easily replaced.

For example, a wire or line based foam can be easily replaced with a piece of foam sponge. It is enough to fix it well in the wire tube. Instead of a fire extinguisher, a propane cylinder is successfully used.

Alternative reservoir

An alternative option to make a manual foam generator would be a regular plastic canister. In this case, it is possible to use the filler cap to secure both fittings.

We attach a plastic tube to one fitting from the inside. Inside, due to dense packing with fishing line, we prepare a foaming device. Outside, we fix the hose with a spray at the end.

We leave the second fitting free to connect the compressor. This is how the simplest contactless sink is prepared with your own hands.

Contactless cleaning from a portable steam generator

The design of the hand-held device differs not only in overall dimensions, but also in the principle of operation. The passing stream of compressed air raises the liquid under the action of a vacuum, and then, under pressure, the solution is sent to the foaming agent.

The devices are sold both ready-made and easily assembled on their own.

The safest for car body paintwork is a non-contact washing method using a foam generator (we also call it foam generators). The essence of this method is to apply a chemical detergent to the surface of the body in the form of finely dispersed foam. After application, it softens dirt and dust, then it remains to rinse everything off with a stream of water. with a paint-and-lacquer coating (rag, brush, etc.) excludes damage to the surface layers of the varnish, that is, the formation of the so-called "cobweb" is completely excluded. Therefore, this method of car washing is now a higher priority and advanced.

The efficiency of washing is in many respects - the higher its density, the better the cleaning properties, the lower the consumption of water and chemicals. And the foam is given just by the foam generator. Therefore, the main task of the foam generator is to obtain finely dispersed dense foam, as well as its uniform distribution over the surface of the car body.

Foam generator design

Structurally, the foam generator is very similar to a conventional garden sprayer, the concept is almost the same. But there is one significant nuance - foam is a high pressure equipment.

The main building blocks of this equipment are:

1. Cylinder (the volume is different - from 25 to 100 liters).
2. Mixer.
3. Pistol.
4. Connecting hose.

Large-sized equipment, with a large-capacity cylinder, can be installed on a transport trolley to ensure easy movement.

Since the equipment operates under high pressure, cylinders are made of stainless or ordinary steel, but with the obligatory coating with anti-corrosion agents. In some factory models, a measuring ruler is installed on the cylinder, which allows you to control the flow and timely refuel.

The foam generator cannot work independently, since the supply of compressed air is required. For this, a compressor connection is provided on the cylinder. Typically, the operating pressure for a foam generator is 5-6 bar. To control the pressure, a pressure gauge is installed on the container, the pressure is adjusted by the pressure regulator available in the design.

Foam tablet

The main element of the mixer is the so-called foaming tablet. In reality, it is a fine mesh, folded in several layers and made of corrosion-resistant wire. It is installed in a housing mounted on a cylinder. And it is to him that the supply hose is connected. This tablet provides a breakdown of the primary foam supplied to it, into a finely dispersed fraction of high density.

The principle of operation of the foam generator

DIY foam generator

The principle of operation of the foam generator is very simple:

1. The washer fills the bottle with a solution of water and a foaming agent (detergent). Then the neck is tightly closed, which ensures the tightness of the container.
2. The compressor is connected and air is pumped to the required pressure.
3. When the valve of the gun is opened, the air begins to squeeze out the solution through the nozzle, where the primary foaming occurs.
4. Moving at a high speed, the foamed solution hits the foaming tablet grid and, passing it, is separated, which is accompanied by the formation of a finely dispersed foam.
5. The finished foam is fed to the gun and then through this nozzle to the surface of the body.
6. If necessary, the washer can adjust the feed on the gun (make the spray front wider, increase the speed of the jet).

It is noteworthy that another equipment for contactless washing works approximately according to this principle - a sprayer. But unlike the foam generator, at the exit from the pistol, it forms an emulsion, in which the washing effect is lower than that of the foam.

The difference between the two comes down to the different spray guns used. An emulsion is a slightly different state of a liquid than a foam, so a nozzle with an enlarged opening is needed to spray it. In addition, it is impossible to adjust the parameters of the emulsion supply with the sprayer, that is, there are no adjusting elements on the gun. These nuances will help you easily distinguish the foam generator from the spray.

The main advantages of the foam generator are:

• economical consumption of detergent;
• the foam obtained at the exit has an excellent washing function;
• the ability to adjust the flow of the jet;

The main disadvantages of this equipment are two - large dimensions and the need to connect a compressor. Of these qualities, the foam generator is considered to be equipment that is not very suitable for home use.

Foam kit as a type of foam generator

In garage conditions, it is better to use a foam kit - a variation of equipment for a contactless car wash.

A gun with a sink attachment. Connected via a hose to a pressure washer

This equipment works in a slightly different way. It also has a capacity, but it is much smaller in volume than that of a foam generator - only 1 liter. It also includes a foaming agent, which immediately plays the role of a gun for application. But unlike foam, the foam kit does not work from the compressor, it is a nozzle for high pressure washers.

A container with a foaming agent, otherwise called a foam nozzle for contactless washing

Foam nozzle diagram

The foam kit works like this:

1. It fits over the water supply hose from the pressure washer.
2. After turning the sink into operation, high pressure water is supplied to the foaming agent, and from there to a container filled with detergent, where primary foaming occurs.
3. The resulting solution in the container is squeezed out by the supplied water again into the foaming agent, where it passes through the foaming tablet.
4. At the exit from the tablet, finely dispersed foam is formed, which is fed through the bell to the surface of the body.

For the convenience of work, extension cords (spears) of different lengths can be connected to the foam concentrate in order to ensure the application of foam to any surface of the car, including the roof and bottom.

The jet obtained at the outlet of the foam set can also be regulated using a valve installed on the foam concentrate.

The foam kit is different:

• small overall dimensions;
• good quality foam obtained at the exit;
• ease of refueling (no water is required to create a solution);

But without a pressure washer, the foam set will not be able to work.

Due to the powerful jet obtained at the outlet, the consumption of the detergent for such equipment is slightly higher than that of the foam. In general, this is a perfectly acceptable option for contactless car wash at home. And the foam kit is much cheaper than the foam generator.

How to make a foam generator for washing yourself

Foam generator assembly

Considering the design of both types of equipment, you will notice that their main component is a foaming tablet, which can be bought separately. This means that it is quite possible to make a foam generator with your own hands.

The easiest way to make it is to take a regular garden sprayer as a basis and alter it a bit. At the beginning, it was mentioned that structurally the foam generator and the sprayer are similar, and this fact is often used when creating a homemade foam generator.

Foam tablet assembly

• sprayer (volume may be different);
• two ½ ”squeegees and nuts for them;
• check valve;
• air fitting;
• foaming tablet and adapter for it;
• metal tube.

Having all this, you can start reworking:

1. Cut off the pressure relief valve and the hose connection from the sprayer.
2. We insert squeegees into the holes obtained and fix them with nuts on both sides and using gaskets.
3. On one of the squeegees, we install a tube (so that it almost reaches the bottom of the container), a check valve and an air fitting.
4. We wind a foaming tablet onto the second squeeze through the adapter.
5. The hand pump for pumping the pressure of the sprayer must be completely shut off, since it is not needed, and will only serve as a tank cap.

Video: DIY foam generator

All that remains is to connect the hose to the tablet outlet, on the other end of which you put a garden spray gun. On this, the product can be considered finished.

It is not as convenient to work with as with factory equipment, but it is quite acceptable. To wash your car you need:

• fill the container with detergent solution (2/3);
• connect the compressor and pump air into the cylinder (it is important to monitor the pressure and not exceed the permissible limits);
• after opening the valve of the sprayer, the air will squeeze out the solution, push it through the tablet, and at the exit from the gun we will get foam of quite acceptable quality;

Of the inconveniences of a home-made foam generator, one can note the need for periodic pumping of pressure, since the homemade product is not equipped with a regulator, as well as the inability to adjust the outgoing stream.

But the described design can always be modified by installing additional equipment in order to eliminate the shortcomings and increase the convenience of working with the foam generator.

This article describes the features of their designs, how to make it for washing, how to make a nozzle.

Car washing has a number of features, the main thing is not to damage the paintwork of the car. On modern car washes, there are not very high-quality pistols that do not wash the car very well and often break down. Gels are foamed using this device or dispensers. You can also wash your car in this way at home. It is worth making such a device yourself.

The structure of the device and its specifics

First, you need to understand the functions and composition of the device, if you want to assemble. This is a metal tank with a capacity of up to 100 liters, consists of a filler neck, a drain valve, 2 fittings, then a nozzle for spraying foam is attached. The tank (2/3) is filled with a special agent (10 ml) and 1 liter of water.

A special shampoo contains wax that protects the car body. When the tank is full, the compressor starts to work, compressed air enters the tank. The pressure must be at least 6 atmospheres. Also, water and product are supplied separately. It is bred in a pistol, it is much more difficult to invent such a mixture yourself.

Foam is formed in the tank and exits through the filter, the sprayer is in the nozzle, the pressure gauge monitors the pressure, and the water measuring tube monitors the degree of filling. Such a device helps a person, he does not interact with chemicals. The washing speed is about 20 minutes.

Pros of the device

• no contact with the car body, prevents paint darkening;
• you can remove dirt in hard-to-reach areas;
• a thin protective film is formed.

If you buy steam generators, they are expensive (depending on the capacity), so they are made with low pressure for the home.

Manufacturing features

If you make it yourself, the cost will be about a couple of thousand rubles, and if you buy it, then about ten thousand rubles. The main elements for the manufacture of the device;

• capacity;
• reinforced hose;
• pressure gauge;
• clamp;
• stop valve;
• a tube.

We select a tank that can withstand up to 6 atmospheres, the volume should be up to 10 liters, so as not to add foam a second time.

Diagram, if you make nozzles with your own hands

There are different types of attachments. What tools are needed for this:

1. Roulette;
2. Bulgarian;
3. Spanners;
4. Pliers.

Prepare an inch pipe at least one and a half meters, a washcloth. How to assemble - cut the pipe at least 0.5 meters, the larger the pipe, the better the quality of the foam. But remember, a large pipe also requires a powerful compressor. Next, you need to clog the pipe with a washcloth and cut the thread at the end, screw a tee onto one of the ends, from the second filler. Install a large filter, put a plug on one of the tee terminals, connect the water source with shampoo and a compressor to the remaining ones.

You can also adapt a conventional garden sprayer and choose the right compressor. Remove the union, the valve from it, remove the pump and install the plug. We get 2 holes in the sprayer, screw in the sleeves and fix, install the gaskets. Screw in a check valve with a fitting into one of the squeegees and install a tank on the other.

When buying a foam sink, be sure to pay attention to the presence of a foam nozzle, if it is not there, then you will have to do it yourself, maybe this is a joy to someone, and significant savings in money. And all the materials can be found at home in the garage, so making a foam generator with your own hands is simple and profitable.

A foam generator is a device that is actively used in many areas. For example, car owners use it for non-contact car wash. The main task of the apparatus is to form foam by creating pressure. To buy such a device for use is the desire of many, but the foam generator is very expensive, and not everyone can afford it. It's another matter if you make a foam generator with your own hands.

Structurally, the foam generator is very similar to a conventional sprayer, the basic circuit is almost identical. But there is one caveat that the foam generator is a high pressure equipment.

The main components of this equipment are:

• balloon (from 25 to 100 l);
• mixer;
• a gun;
• hose.

Large equipment with a large balloon capacity can be mounted on a transport cart for easy movement.

Since the equipment operates under high pressure, cylinders are made of stainless steel or metal with an integral anti-corrosion coating. In some industrial versions, a straight ruler is installed on the cylinder, which makes it possible to control the flow and timely filling.

The foam transformer cannot work on its own. The normal operating pressure for the foam generator is 5 - 6 bar. For control, a pressure gauge is installed in the tank, pressure control is performed by the existing pressure regulator.

Purpose and principle of operation

Foam sprays are very popular. They are used in technological service stations, in the fire, pharmaceutical and food industries.

The active composition of the foam contributes to excellent cleaning:

• production equipment;
• road transport;
• premises after renovation;
• swimming pools.

The action of the foam is aimed at cleaning the surface, removing dirt, and disinfecting.

The main component of the device is the so-called foaming tablet. In fact, this is a lattice with a small mesh, closed in several layers and made of corrosion-resistant wire. It is defined in a housing mounted on a cylinder. And it is connected to the supply hose. This tablet ensures that the fine grain foam is delivered at a high frequency.

And then the foam goes to the gun, which is applied to the plane. This hand gun is equipped with a flow regulator, which makes it possible to set the parameters of the jet.

Do-it-yourself washing machine

Considering the hardware system, you will notice that the main component is an expandable tablet, which can be purchased separately. This means that you can make a homemade foam generator without any problems. The easiest way to make a contactless device is to take an ordinary sprayer as a base and recycle it a little.

Thus, you need:

• stabilizer;
• two half-inch drills and nuts for them;
• check valve;
• air duct;
• foam and adapter;
• metal tube.

It is worth considering one of the simple designs of the foam generator, which can be made from improvised means. It is important to follow the instructions.

Work order:

• it is necessary to disconnect the valve and the connecting hose from the sprayer;
• insert bushings into the holes and fix them with nuts on both sides and with gaskets;
• install a pipe on one of the actuators so that it almost reaches the bottom of the tank, a check valve and an air supply connection;
• on the second disk adapter;
• the pump must be cushioned as needed.

It remains only to connect the hose to the outlet. Thus, the product is ready. The device is not as convenient to work with as with the factory equipment, but it is acceptable.

For washing you will need:

• fill the container with a cleaning solution by 2/3;
• connect the compressor and supply air to the cylinder (it is important to monitor the pressure and not exceed the norms);
• after opening the spray valve, the air squeezes out the solution, passes it through the tablet, and at the outlet the foam is of quite acceptable quality.

Among the disadvantages of the foam generator, one can single out the need for periodic pumping of pressure, since the controller does not have a regulator. There is also no exhaust flow regulation.

But the described design can always be improved by installing additional equipment to eliminate the disadvantages and improve the usability of the foam generator.

The apparatus from a plastic canister

This method is even easier than the previous one. It makes it possible to collect a foam source for cleaning from appliances with minimal cost. Not much is needed for the product. Making a foaming agent for washing with your own hands is not difficult.

This only requires:

• set of wrenches;
• Bulgarian;
• pistol;
• plastic containers;
• nozzles;
• compressor;
• flushing hoses.

It is necessary to take a tube 70 cm long. Both ends must be closed with special plugs. The plugs must be fitted over the threaded holes.

On one of the plugs of the foam generator, you need to put an adapter in the shape of the letter T. On the second, fix the connection. Connect hoses to 2 outlets of T-adapter. Do not forget about the stopcocks.

One arm of the foam generator for washing will lead to the reservoir of liquid, and the other to the compressor. This kind of method makes it possible to compose a generator at home with your own hands at the lowest cost.

In the event that a homemade foam generator is turned on for washing a car for the first time, you need to supply plain water with a small amount of dye. This will help identify weaknesses in the structure, if any.

Alternative tank view

When assembling a foam generator with your own hands, choosing the correct reservoir is of particular importance. Simple ways have been shown earlier. There is one more option.

Making a foam generator for a car wash with your own hands will not be difficult. To form a foam generator with your own hands for washing a car from a propane cylinder, you must use welding. It is necessary to weld all the old holes and make 2 new ones: one at the bottom point of the end, the second in the middle. Weld pipes with fittings.

Both collet adapters and couplings can be used. The main thing is that this self-made component of the foam generator installation can withstand the pressure that is generated by the compressor.

For the greatest convenience, the hatch can be made for the foam generator. The container must be completely airtight. The lower tank connection connects directly to the compressor, the upper connection connects to the atomizer. As you can see, the principle of switching on the tank from a propane cylinder is the same. However, the period of work and reliability are many times higher.

Conclusion

Creating a device like a foam generator for a Karcher washing with your own hands takes time and effort. However, the result fully compensates for all costs. Now any car wash will be practically free.
