Homemade foam nozzle for car washing. Homemade foam generator - we make active foam at home. Improving the device - installing additional parts

A foam generator is a device that is actively used in many areas of our life. Motorists know about it as a device for a contactless car wash.

The main task of the apparatus is the formation of foam by creating high pressure. The foam is ejected after pressing the special “pistol” lever.

Despite the “softness” of action, the foam composition provides high-quality cleaning of the body and other surfaces from the most “corrosive” contaminants.

To get such a device for use is the dream of many motorists. The only problem is the high price.

An industrial foam generator is too expensive and not everyone can afford it.

Another thing is if you make a device with your own hands. So you can "kill two birds with one stone" - get a powerful car wash machine and save money.

But how is this possible? What are the methods?

Industrial foam generators: purpose, principle of operation

As already mentioned, foam generators are very popular products. They are used in service stations (when washing cars), in firefighting, pharmaceutical and food industries.

The active composition of the foam contributes to high-quality cleaning:

production equipment;
road transport (from the inside or outside);
industrial premises (floors, walls, etc.);
sidewalks and swimming pools.

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

It is thanks to the complexity of the action that foam generators have become so popular.

Structurally, the device consists of three elements:

a cylinder containing compressed air;
outlet gun, which provides convenient foam supply;
mixer elements.

One of the main parameters that affect the functionality of the device is the capacity of the cylinder, which can be from 25 to 100 liters. There are some models that hold 24 liters.

Stainless steel or ordinary steel is used as a material for manufacturing.

The principle of foam formation takes place in two stages:

a foam composition is formed, which has a low expansion rate and is still unsuitable for use;
the mixture is fed to a special “tablet”, which forms the required composition with the desired density.

Do-it-yourself foam generator

To get a foam generator at your disposal, it is not at all necessary to buy an expensive device - you can do everything yourself. Here are the following options:

1. The first way.

It is considered the simplest and allows you to make a generator from improvised materials.

Of course, in terms of its functionality, the device will lag behind its factory counterparts, but in everyday life it will be difficult to overestimate its benefits.

The following equipment is required to perform the work:

Bulgarian;
roulette;
set of wrenches;
pliers.

The work is carried out in the following sequence:

use a pipe (inch) about half a meter long. Hammer the front of the product with a plastic washcloth, which is designed to form foam.

make a plug for one of the edges of the pipe and screw a special tee into the same place. After that, connect the tap to the foam generator to the inlet hole.
on the other side of the pipe, install a valve through which compressed air will be supplied from the vehicle compressor;
the second pipe outlet is connected to the foam hose through a special fitting. To prevent the washcloth from getting into the tube, do not forget to install a special filter. In this case, the filter element may have large sections.

The schematic diagram is proposed below.

Please note that the density of the produced foam depends on the length of the tube and the density of its stuffing with a washcloth.

As a liquid tank, you can use any container that can withstand the pressure of the compressor. In this case, the material does not really matter.

If everything is done correctly, then such a foam generator will perfectly cope with washing a car or other items in a garage.

2. The second option.

Production of a foam generator that is structurally similar to the factory type of the product (with the exception of some differences).

Keep a few things in mind right away:

pick up and buy (it must have enough power to create optimal pressure);
buy or take an existing sprayer. Its walls must be thick enough to withstand five atmospheres;
remove the mounting fitting and valve from the sprayer. As a result, there should be two holes at the exit. At the same time, disassemble and turn off the hand pump;
prepare the necessary tool (equipment) for work - a check valve, a foam tablet, a pair of squeegees (0.5 inch) and four nuts, a tube adapter, an air fitting and gaskets.

screw the spurs into a plastic tank and tighten them with nuts. Be sure to install new gaskets that will provide the necessary tightness;
choose any of the spurs and screw the check valve together with the fitting;
on the other side, fix the tank to combine with the fixed tablet inside the device.

That's all - a homemade steam generator is ready. It remains only to attach the tube to the overhang through which air is supplied.

It is important here that air enters the device from below (this will ensure full foaming of the liquid).

It will take some time to work with the hose. The easiest option is to attach a regular tree sprayer to its edge.

Now pour water into a special cleaner (10:1 ratio to shampoo). Make sure that the neck is tightly screwed in all the time the foam generator is in operation.

At the same time, open the tap and start the sprayer. On average, about 20-40 grams of shampoo is consumed per wash.

Monitor compressor pressure. Normal operation is ensured when 4-5 atmospheres are reached.

The total cost of collecting the foam generator (in this form) is about 2-3 hours. If all of the above equipment is at hand, then the only cost will be the purchase of shampoo.

3. The third way.

Allows you to make a foam generator from an ordinary plastic canister. The advantage of this technique is ease of implementation, minimal time and money.

To work, you will need a compressor, a nozzle, a gun, a plastic canister, a grinder, a set of keys and flush tubes.

The algorithm should be the following:

take an inch tube with a length of 70 centimeters and fill it with ordinary fishing line. You can use all the products that are at hand (the cross section does not matter);
close both edges with special plugs. At the same time, make sure that there is a thread in the latter;
install a T-adapter on one plug, and a fitting on the second;
on both sides of the adapter, made in the form of "T", fasten the hoses and install taps to stop the water supply;
one end of the washer foamer will go to the foam tank and the other end to the compressor.

Before turning on the foam generator for the first time, pour a small amount of water and a little dye into the container. This allows you to identify weaknesses in the design (if any).

The options are shown below.

Other methods.

Alternative tank options, what can be used?

As we have already seen, when assembling the device yourself, it is important to choose the right water tank. The main requirements are sufficient volume and the ability of the material to withstand high pressure.

The above are the simplest methods in which ordinary (handy) containers are involved.

If we proceed from reliability, then the best option is a propane tank.

The peculiarity of such a container is the ability to withstand enormous pressure. As a result, the efficiency of the foam generator also increases.

The fact of safety is also important. You can calmly build up pressure without worrying about a possible rupture of the container or failure of the device.

To use a propane tank for work, you will need special welding.

First, all extra holes are welded, after which new holes are made. The first is from the bottom of the end part, and the second is in the middle.

Pipes with fittings should be welded to the holes made.

As a material for fasteners, couplings or collet adapters can be used. The main thing is the ability of each of the structural elements to withstand the pressure created.

To simplify the process of using the foam generator, make a special hatch for refilling shampoo.

Pay special attention to the tightness of the cylinder. To do this, do not forget to put a special seal.

The lower part of the fitting must be connected directly to the compressor, and the upper part to the atomizer.

As can be seen from the diagram above, the principle of connecting the cylinder does not differ much from the schemes described above. The main plus is a longer service life and reliability.

Alternative options for creating an atomizer

Lack of fishing line at hand is not a problem. As mentioned in one of the methods, a synthetic washcloth or foam rubber sponge can act as a sprayer.

All that is needed is to cut out the desired part and press it into the tube. When doing this, make sure that the product is well fixed inside and does not collapse under high pressure.

An equally important task is to properly fix the filter, which plays a direct role in the formation of bubbles.

How to reduce the size of the foam generator?

It is no secret that the industrial samples of foam generators are large and not always easy to use.

Another thing is homemade devices that can be upgraded at your own discretion. How?

Everything is simple here. For work, prepare a small tank (for a gun) and a nozzle for a high-pressure apparatus.

Close one side of the pipe with a nozzle, and the can itself with a container for an aerosol gun (alternatively, you can use a standard sprayer).

Such modernization is an opportunity to reduce the volume of the structure by 2-3 times. At the same time, the device itself, thanks to the presence of wheels, can be moved to any convenient place.

How to save on materials?

As practice shows, it is not always possible to find everything you need in the garage. The only way out is to save money. To do this, proceed as follows:

always buy new parts so as not to overpay several times later;
have a good dig in your garage or your friend's garage (with agreement, of course). Most of the spare parts can be found in the old "deposits".

In the absence of the necessary elements, the cost of purchasing a compressor will be about two thousand rubles. But you can cheat. For example, as an option - to dismantle the necessary equipment from an old truck.

If you can’t find the right equipment among your friends, you can look at ads for the sale of cars for spare parts.

As a last resort, you can go to a car dump, where there are plenty of old ZIL-130s. In this case, the desired part can be obtained for "penny".

Check the unit carefully before buying. It should not have oil leaks or other defects. Otherwise, it is dangerous to work with the compressor.

Even if you manage to start a do-it-yourself foam generator for washing, but equipped with a defective compressor - 1-2 cleanings and the device will fail.

Results

The foam generator is a reliable assistant in the garage, which will speed up the washing process and increase its efficiency, while you have two options:

purchase a finished design;
make a foam generator with your own hands.

As you have already seen, the second option looks more preferable due to lower costs.

On the other hand, do not count on quick readiness. For manufacturing, you will have to go through several stages:

study recommendations for manufacturing;
find the necessary material;
spend time on the manufacture of the device;
test his work.

If you are ready for this, then you can safely get to work. We invite you to watch the video. Good luck.

The foam generator is a device that generates and ejects foam onto the car body. Such equipment is the desire of many car lovers, and therefore they are interested in making it with their own hands and using it in the future to wash their own car. The fact is that the device is quite expensive, and therefore, it is much easier to make it yourself.

Any foaming agent for a car wash, even a self-made one, consists of the following parts - a cylinder containing compressed air, a mixer, a hose and a special gun for spraying foam. The most important is, of course, the cylinder, on the volume of which the entire operation of the foam generator depends. Its volume can reach 100 liters, but in our case 25 will be enough.

To prevent the cylinder from corroding, it is advisable to use stainless steel for this. Therefore, he will have to deal with a large number of chemical elements.

Foam formation can be divided into two stages:

First, a special composition is prepared from water, in which the detergent is diluted. So far, this is an unusable foam and does not have the necessary properties in order to get on the car body in the right amount.
The composition enters a special "tablet", where the final formation takes place. It creates not only the desired properties of the foam, but also the necessary density, which allows it to be sprayed.

The foam generator allows you to develop a composition that allows you to clean the car body without touching it with a rag. That's what makes him so popular.. But in order to acquire this device, it is not at all necessary to spend a lot of money, because you can safely assemble it with your own hands.

How to make a foam generator

Consider several ways to make a foam generator with your own hands at once. And let's start with the simplest.

Of course, such a foam generator will not have the same effect as the factory ones, but it definitely will not be superfluous in a car wash. Prepare the following list of tools in advance: knife, grinder, wrenches, measuring tape and pliers.

Take a pipe with a diameter of 1 inch and a length of no more than 0.5 meters. At the very end of the pipe you need to place a washcloth made of polyethylene. This approach will accurately create the desired dispersion and foam formation. To prevent the washcloth from being squeezed out by pressure, install a special filter at the end.

Now you need to attach a tee to the free end of the pipe. It should be said right away that two cranes should be installed on it. Compressed air will be supplied through one hole, and foam itself through the other. Accordingly, one of the pipes will go to the cylinder, and the second to the next tee for compressed air, which will be supplied to both the cylinder and the gun itself.

It should be noted right away that the density of the foam will depend on the length of the pipe. But it is not recommended to make it too long, as such a foam generator may not be very convenient. In addition, only a schematic diagram is described here. In reality, it is necessary to have a hose between the pipe and the tee for ease of use.

The second method involves using a plastic canister instead of a conventional cylinder. At first glance, it will seem that making such a foam generator with your own hands is very simple, but in reality it is more difficult than the first option. Such a device is suitable for washing small cars, for example, "Oka". In this case, the tube is taken longer and the diameter is smaller, although any section can be used. Instead of a washcloth, an ordinary fishing line is laid inside, moreover, in a chaotic way. It is necessary to put a filter on one end of the pipe, and a special fitting for the hose on the other. Several fittings must be purchased.

The compressor and the gun itself are also connected to the canister. Before using for the first time, pour a small amount of water into the frother as a test. This is necessary in order to identify all leaks and eliminate them before further use of the device.

It is not excluded the use of other containers for foam. The main criterion is the ability of its walls to withstand sufficient air pressure. You need to take this seriously, because if the tank explodes, you can get quite serious injuries. In addition, it is not necessary to use an overly powerful compressor with insufficient cylinder capacity.

By the way, a foam sponge can be considered a good foam sprayer, which has smaller sections and is best suited for creating good and whipped foam.

Now you know how to assemble a good do-it-yourself foam generator. This will help you avoid unnecessary spending on expensive equipment.

Features of car shampoos

The use of low-quality car shampoos can lead to such negative consequences as:

Blurred bodywork and glass.
Remains of dirt and grease stains.
Divorces and stripes.

Incorrectly selected cosmetics can lead to damage to the bodywork. Many car enthusiasts prefer to make car shampoos with their own hands. However, in order to give examples of various recipes, you need to know the features of car washes.

Car wash technologies

Today, there are two options for bringing your iron horse back to its normal appearance:

Special car shampoo

Contact a car wash.
Use detergents and wash the car yourself.

In any case, a professional touchless car wash is necessary and indispensable. This is due to the following factors:

Provides a lot of foam.
You can easily wash off dirt, oil and other contaminants that car shampoo can not cope with.

Please note that there are several washing options: manual or touchless car wash.

Benefits of professional car cosmetics

Using a foam generator

The use of professional branded cosmetics has a number of advantages. Their recipe, properties, foam and consistency are ideally combined with each other and make it possible to:

Ensure the highest quality of cleaning the body, glass or headlights of the car from dirt.
Cause minimal damage to bodywork, as well as all metal or plastic parts.

Varieties of car shampoos

All car shampoos are divided into the following varieties:

For contact washing, which are used for washing with a rag.
Contactless. Designed for high pressure washing.

In the automotive market, there are various nozzles that are mainly designed for contactless washing. Their design, shape and quantity contribute to the formation of intense foam.

According to the recipe and consistency, car shampoos are:

Powdered, which must be dissolved in water until foam appears.
Pasty, which are applied to the surface or dissolved in a small amount of water.
Liquid.

Gentle option - do-it-yourself car shampoo

If the purchase of shampoo in a car shop for some reason does not suit you, then you can learn how to make it yourself. To do this, you need nothing at all: a bottle of high-quality shampoo, where its composition is indicated. The recipe is simple and clear. To create cosmetics, we do the following steps:

We exclude in the composition all chemical components that are not always possible to buy in stores.
We make a list of elements that are most accessible.
We find the most common shampoo for hair.
We add the necessary elements and get a car shampoo for contactless washing.

This simple method is the safest and most inexpensive when compared to buying a ready-made mixture. Autochemistry is done independently in a jiffy, but it still turns out good foam.

Let's analyze the detergent, which you can make yourself from improvised ingredients. It consists of substances of one of the following categories:

Natural base: animal or fish oil, vegetable oil, wax.
Synthetic materials: propylene, paraffins, ethylene.
Substances that reduce the hardness of water and increase the fluidity of the detergent.
Foam formers, thanks to which the foam improves the quality of washing and increases the speed of removal of contaminants.
Various anti-corrosion additives that the foam contains.

In addition, to make your car shampoo as similar as possible to the industrial one that is presented in stores, you can add a little polishing or deodorizing ingredients to it.

The proportions of the components are chosen by each car owner independently, through trial and error. After mixing the composition, a high-quality car shampoo is obtained, which can be used for contact or contactless washing. In the first case, the solution is applied to the contaminated surfaces with a brush, and in the second case, it is filled into the foam generator, after which foam appears ()

How to use homemade chemistry for cars

There are no beneficial differences between homemade and homemade chemistry. Shampoo for touchless washing, which you prepare yourself, you just need to dilute in water. Then we perform the following simple steps:

We apply shampoo with water to the car body with a washcloth, while not rubbing too much.
We wait a couple of minutes for the shampoo to remove the dust.
Again, wash off the shampoo with a brush, only now with dirt.

You can also polish your car, but not more than once a year. To do this is somewhat more difficult and responsible, so it is better to buy high-quality cosmetics. After washing off the shampoo, it is enough to wipe the surface with a cloth, which will get rid of unwanted marks on the body.

After preparing the shampoo with your own hands, you can immediately start washing. Depending on the consistency, it must be diluted with water. It is better to add less car shampoo, as a high concentration can damage the coating.

Apply the diluted product carefully, shaking before that until foam appears. After washing, be sure to use special napkins or a dry soft cloth.

Don't let the water dry out as this can lead to multiple streaks. Do not abuse chemicals that contain wax. Literally in a couple of days from such processing, the body will be covered in dust, and it will be possible to wash it only at a specialized sink.

Ignoring these tips can lead to surface destruction, as well as negative side effects. Non-contact chemistry is the best way to clean the car and keep it shiny without any streaks and marks.

In order for the car to have an attractive appearance, and the paintwork to be in perfect condition for as long as possible, you should regularly wash the car using a good car shampoo with the right composition.

This article is intended for persons over 18 years of age.

Are you over 18 already?

Often, car owners who want to save on car wash services prefer to wash cars on their own, while making car shampoo with their own hands. Making your own detergent is not difficult, but you need to remember that the wrong composition can ruin the car's coating.

Car wash

If you decide to cheapen the process of washing your iron horse and do it yourself, before you start making a washing agent, familiarize yourself with the recipe and purchase quality ingredients. The composition of the shampoo must be professional, because:

the washing solution should form a lot of active foam;
wash not only dirt and dust, but also bitumen stains, soot, gasoline, oil;
shampoo should be for manual and contactless washing and be in different containers (jars, canisters).

Some drivers use ordinary shampoos or dishwashing detergent to wash their cars. They cope with dust and dirt, but oil and soot remain on the surface even after washing. Sometimes vehicle owners do not delve into the recipe needed to prepare the solution, and then aggressive chemistry spoils the varnish on the surface of the body, which incurs considerable restoration costs.

In order for the vehicle to look well-groomed, the varnish to shine, and the optics to be in perfect condition, you need to use only high-quality detergents designed specifically for washing cars. This will increase the attractiveness and reduce the accident rate. Car shampoo is one of the main components for car care.

Types and features of funds

There are many types of car shampoos. They differ in consistency, aggressiveness, additives, etc.

There are the following types:

For contact washing. These shampoos are designed for hand washing with a cloth or sponge.
Contactless car wash. The method involves the use of water supplied under pressure.

GRASS foam for contactless car wash

To date, the automotive market offers funds intended mainly for the second type. They are characterized by the formation of a large amount of foam, which acts on dust and dirt, removing it from the surface.

By consistency, the funds are divided into the following types:

in the form of a powder that dissolves in water, simultaneously forming a foam;
pasty, rubbing on the surface of the car until a foamy layer appears;
liquid, which are poured into special equipment, and immediately cover the car body with foam.

Recently, various products have been added to car shampoos that provide a light polish to the body or form a thin film of wax.

A simple gentle shampoo

How to make a car shampoo with your own hands? To make a homemade washing solution for washing, you will need a container from a quality product on which the composition is written. We carefully study it and begin to act. We write down all the components, excluding chemical ones. We purchase the most common hair shampoo, not necessarily expensive, a simple one is fine, add what is written on your list, and the car shampoo for contactless washing is ready.

Regular hair shampoo

This method is the safest for both the owner of the car and for the paintwork, but it will certainly not cope with complex dirt in the way you want it to. But it is economical, easy to manufacture, forms a lot of foam and makes the car look pretty clean.

Never use mixtures of cheap chemicals to make shampoo. By doing this, you will not only undermine your health, but also spoil the car coating. It will become cloudy, remaining all in the same dirty spots, and, possibly, will corrode the varnish layer. Glasses can also lose transparency.

Learn about car washing. What kind of species are there, what means should be used in a particular case, what chemical components are harmful. Only after that, start learning the basic recipes for car shampoos.

Car shampoo recipes

On the Internet you can find a whole bunch of recipes that promise us the perfect ratio of price and quality of the resulting product. If you want to make the perfect store-bought product, make sure you stock up on deodorant fragrances and polishes. A small number of them will need to be included in the composition.

So, what does do-it-yourself foam for contactless washing include:

Surfactants.
Foaming agents.

Do-it-yourself car shampoo

The main thing with which we begin the preparation of our solution is the base. In good natural compositions, the basis is water with a pH of 7. It is gentle on chrome and varnish. Having decided on the type of sink, you can add the following components. For manual washing, they should be less aggressive. The most popular surfactants used in car shampoos are anionic and nonionic.

The next thing that is added is complexing agents. They are used to reduce the hardness of water. If you do not add this component, it will lose fluidity, which will complicate washing in hard-to-reach parts of the car body.

These include:

foam formers, which are responsible for the formation of active foam;
polyphosphates, silicone resins, anti-corrosion additives;
polishing agents that protect against chemical damage and slight mechanical impact;
fragrances used to ensure that after washing there is no smell of chemicals that make up the shampoo.

You can mix all the ingredients yourself, without following strict rules. If you feel that it is difficult for you to cope with this task, and do not know what and how much to add, buy car shampoo in the store. This will save you from mistakes, the price of which will be damaged paintwork of your vehicle. Do-it-yourself active foam for a contactless car wash, prepared correctly, will serve you no worse than purchased at a car dealer.

Active foam for touchless do-it-yourself washing

How to use auto chemistry correctly

A home-made car shampoo has practically no differences in application, compared with an industrially prepared detergent. The principle of operation is the same for them, the result, if used correctly, will also not differ. You can start using the detergent immediately after you have prepared it. Given the consistency of the shampoo for contactless washing with your own hands, it must be diluted with plain water.

In order to wash a car, you need to apply a diluted product to the surface, rub it over the car body until a rich foam forms and leave it for a while. At this point, the detergent composition will remove dust from the surface. Then, use a brush or sponge to wash off the car shampoo from the car and wipe it dry.

Wipe glass surfaces and mirrors with a soft, lint-free cloth or special wipes.

The detergent must not be allowed to dry on the paintwork. This will lead to stains and streaks.

In case you are not sure how much shampoo to use for car washing, it is better to use less. A concentrated solution may damage the lacquer.

For contactless washing, equipment is used, in the presence of which you do not have to do physical labor and rub the detergent on the surface of your car.

Microfiber glass cleaning cloth

In order to wash your iron friend, you will need a gun, a spear and a steam generator.

First of all, dirt, sand and dust with abrasive particles should be washed off the machine with ordinary water. This will prevent the paintwork from forming small scratches. Further, with the help of equipment, a detergent is evenly sprayed onto the body. With the help of a steam generator, an ordinary solution of car shampoo and water turns into a resistant foam.

Leave the car for five minutes so that the chemical components act on complex contaminants and corrode them. The composition of the car shampoo for contactless washing allows you to cope with even stubborn dirt.

The last step is to wash off the foam from the machine.

Car washing is an important means of maintaining the attractive appearance of the car and the preservation of its paintwork.

It doesn't matter what tool you use, homemade or industrial. Observing the safety precautions and the rules for using the cleaning solution, the car will thank you with the shine and cleanliness of the body surface.

Washing your car is an important way to keep your car looking good.

Rules, the observance of which will help to avoid damage to the varnish coating during washing:

the dried solution leaves stains and stains;
glass, mirrors and headlight caps should be wiped dry immediately after washing;
a solution of high concentration is diluted with water and quickly triturated until foam is formed;
concentrated agent spoils the paintwork.

In difficult times of crisis, everyone is trying to save on something. Car owners are no exception in this case. After all, today the content of its "iron horse" takes a large part of the budget. And if it is unlikely that it will be possible to save money on spare parts and fuel without consequences, then it is unreasonable to constantly spend a lot of money on a professional one. Not washing the car or washing it less often is also not an option, because a dirty car is uncomfortable and even unpleasant to drive.

Everyone solves the problem with car wash in different ways. Some people wash their own houses. However, it takes a long time and is not as effective, of high quality as. And the thing is that professional equipment is used there - foam generators, which help to wash the car as quickly and efficiently as possible. Yes, and contactless washing (using a foaming agent) practically does not harm the paintwork of a car, unlike a conventional contact washing at home.

Others are thinking about buying a mini foam generator to use it exclusively for personal needs. However, the prices for it today are very bite. That is why our craftsmen began to think about how to make a foam generator for washing on their own.

What is needed for a homemade foam generator?

The materials for the manufacture of a homemade foam generator will need the simplest. Almost every house or garage has some of them, although some will still have to be bought. The most expensive part of this device is the compressor. You will not buy a new one on the market for less than a few thousand rubles. However, there are ways to save money too. You can buy an old compressor at a parts sale. For example, with ZIL 130. Its power is quite enough for a home foam concentrate. The main thing is to make sure that it is in good condition, it doesn’t leak anywhere, because this may indicate its imminent failure. If you haven’t found anything suitable for sale, you can try looking at car dumps, where most of these trucks “rest” today. And then, if you find something worthwhile, just negotiate with the watchman and pick up the compressor for a purely symbolic price.

Another equally important element is the fluid reservoir. It can even be an ordinary plastic canister. The most important thing is that the walls of the tank can withstand a pressure of 5–6 atm.

Also, in order to make a foam generator for washing, you will need nozzles, adapters, a gun, flushing hoses and an inch tube, at least 70–80 cm long. From the tool - wrenches, a grinder.

Assembly of the foam generator

Assembling a foam generator for washing with your own hands is quite simple. First, take the already prepared tube. For foaming, it is filled with fishing line of different sections. If there is no fishing line, then you can take an ordinary household washcloth. Next, the required size is cut out and the tube is filled with it. When using a washcloth instead of fishing line, it is very important to securely fix it so that it does not crumple in the tube under high pressure. We close the tube on both sides with threaded plugs. On one side of the pipe, a T-shaped adapter is screwed, shut-off valves. They are connected to hoses. One hose leads to the compressor, the other is inserted into the tank.

On the other side of the pipe, a fitting is fixed, from which foam will come out. Its quality and density directly depend on how long the pipe is and how well it is filled with fishing line or washcloth.

If you decide to use a metal container as a tank, for example a gas cylinder, then welding will also be required here. You will need to weld the old holes and make new ones: one at the bottom and another one somewhere in the middle. Tubes with adapters are welded to them. The lower adapter is connected by hoses to the compressor, and the upper one leads to the spray tube. Before using in both cases, it is better to check if the container is leaking. To do this, instead of shampoo, we use water with a dye, which will indicate to us the place of the leak, if any.

The fastest way to make a foam concentrate

A home-made foam generator for washing can also be made from a conventional sprayer, which is very similar in design to a factory foam concentrate.

It is most convenient to make a foamer for washing from a sprayer. The design of such a device is very similar to factory foamers, although it has some differences. When choosing a sprayer, consider the thickness of its walls, because there will be high pressure in the foaming agent (up to 6 atm).

For this device, you will also need a compressor. Plus a foam tablet, an air nipple or tube, gaskets, a hose adapter, a check valve, a couple of half-inch adapters, and four nuts.

Take the sprayer and remove the mounting valve and fitting from it. You have a couple of through holes in your sprayer. You should also disassemble and plug the hand pump.

After that, take the adapters, twist them into the tank and tighten them with nuts. It is better to use gaskets at the same time to make the container airtight. A check valve with a fitting is screwed into one of the adapters, and a hose from the compressor must also be attached here so that air enters from below to form foam. And an adapter with a fixed foam tablet is placed in another hole. After that, a hose is attached to it. A spray gun is attached to the other end of it (you can take a regular, garden one).

Ways to upgrade

When the issue of creating a foaming agent is closed, everything is already there, it works great, you always want to use it more and as comfortably as possible. Here you can come up with many innovations. Someone attaches an additional atomizer. Others attach a pressure washer attachment instead of a tube.
