This article describes the features of their design, how to make it for washing, and how to make a nozzle.
Car washing has a number of features, the main thing is not to damage the paintwork of the car. Modern car washes have low-quality guns that do not wash the car very well and often break. Gels are converted into foam using this device or dispensers. You can wash your car this way at home. It is worth making such a device yourself.
The structure of the device and its specifics
First, you should understand the functions and composition of the device if you want to assemble it. This is a metal tank with a capacity of up to 100 liters, consisting 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 product (10 ml) and 1 liter of water.
The special shampoo contains wax, which protects the car body. When the tank is full, the compressor starts working, it comes out compressed air into the tank. The pressure must be at least 6 atmospheres. Also, water and product are supplied separately. It is diluted in a pistol; it is much more difficult to invent such a mixture yourself.
Foam forms in the tank and comes out 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 from 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 home use.
Manufacturing Features
At self-production the cost will be about a couple of thousand rubles, and if you buy it, then about ten thousand rubles. Basic elements for manufacturing 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.
Scheme if you make the nozzles yourself
Exist different types nozzles What tools will you need for this:
- Roulette;
- Bulgarian;
- Spanners;
- Pliers.
Prepare an inch pipe of at least one and a half meters and a washcloth. How to assemble - cut the pipe to at least 0.5 meters, the larger the pipe, the better quality foam. But don’t forget, a large pipe also requires a powerful compressor. Next, you need to hammer the pipe with a washcloth and cut a thread at the end, screw a tee onto one end, and filler on the other. Install a large filter, put a plug on one of the terminals of the tee, and connect a source of water with shampoo and a compressor to the remaining ones.
You can also adapt a regular garden sprayer and choose the right compressor. Remove the fitting and valve from it, remove the pump and install the plug. We will get 2 holes in the sprayer, screw in the clamps and secure them, install the gaskets. Screw into one of the brackets check valve with a fitting and install the 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 will be a joy for 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.
Touchless car wash is still considered a luxury for many car enthusiasts. During a crisis, spend 200-300 rubles to wash your iron horse- not the best practical solution.
Of course, you can buy a mini-car wash, but the price often reaches 10-15 thousand rubles. But there is a way out! Assemble a foam generator for washing with your own hands. Moreover, its cost will be several times lower than if you bought a finished product.
The only expensive element of a foam generator for washing is the compressor responsible for pumping air. But it can be purchased on the secondary market for relatively little money (low-power model).
Purpose and principle of operation
Before you start assembling a foam generator for washing with your own hands, you need to understand the principle of its operation. The device performs two functions: it forms foam and distributes it evenly over the entire surface of the car.
The water stream passes through a special solution in the tank and mixes with the air stream. As a result, foam is formed. However, this is not the whole process. Inside the foam generator for washing, the blown substance must obtain the required density. To do this, soapy water is supplied to a special foaming tablet.
Important! The foaming tablet is resistant to corrosion, so you don’t have to worry about its safety.
The control plates are located in parallel. As a result, the fluid flow becomes flat. The long hose of the device allows you to thoroughly wash your car with comfort. Since the principle of operation is more or less clear, you can start assembling a foam generator for washing with your own hands.
Comment! As detergent The foam generator uses special car shampoo.
Assembly methods
There are many methods for assembling a foam generator for washing with your own hands. In most cases, to create this device, there are enough components that can be found in any garage.
The drawings of a foam generator for washing are not particularly complicated. It is not surprising that most car owners decide to make this unit with their own hands.
Simple and fast
Attention! First you will need to buy a compressor.
The most convenient way to make a foam generator for washing with your own hands is from a sprayer. The design of this device is almost identical to the factory tank, excluding, of course, some differences.
Important! Please note that the walls of the sprayer must be thick enough to withstand a pressure of 5 atmospheres.
Remove the valve and mounting fitting from the sprayer. In the end you should get two through holes. The hand pump must be disassembled and plugged. Next, you will need the following elements to create an effective foam generator:
- two half-inch rivets and four nuts;
- check valve;
- air fitting;
- pipe connection barrel;
- foam tablet;
- hose adapter;
- gaskets
Screw the squeegees into a plastic tank and tighten them with nuts. Don't forget to use spacers. They are needed for tightness. Select one of the fittings and screw on the check valve with fitting. On the other, install a barrel to connect with the tablet fixed inside. That's it, the foam generator for washing is made with your own hands.
Important! You need to attach a tube to the outlet through which air is supplied. It is necessary that the air enters from below. Due to this, the liquid will foam.
True, you still have to tinker a little with the hose, but it won’t take much time. Simply attach a garden sprayer to the end.
After you have made the foam generator for washing with your own hands, you need to pour water and a special cleaning agent inside. The proportion is 10 to 1. During operation, the neck should be tightly screwed. Turn on the air supply and activate the sprayer. The average consumption of car shampoo is 20-50 grams per wash.
Important! The compressor must create a pressure in the range of 4-5 atmospheres.
As you can see, the design of a steam generator for washing a garden sprayer is not particularly complicated. On average, the unit can be assembled in 2-2.5 hours.
How to make a foam generator for washing from a plastic canister
This method is even simpler than the previous one. It allows you to assemble a foam generator for washing from available materials at minimal cost. To do this you will need:
- set of wrenches,
- Bulgarian,
- gun,
- plastic canister,
- nozzle,
- flushing hoses.
Take an inch tube 70 cm long. Fill it with fishing line of different sections. As a result, there should be formed homemade mesh. Both ends are closed with special plugs. The plugs must have threaded holes.
Install a T-shaped adapter onto one of the foam generator plugs. Attach a fitting to the second one. Attach hoses to the two outlets of the T-piece. Don't forget about the shut-off valves.
One hose of the foam generator for washing will lead to a reservoir with foamy liquid (canister), the other to the compressor. This method allows you to assemble a foam generator with your own hands at home at minimal cost.
Important! When you first turn on your DIY washing steam generator, fill the tank with plain water with a small amount of dye. This will allow you to determine weak spots structures, if any.
Alternative type of detergent reservoir
When assembling a foam generator for washing with your own hands, selecting the right tank is of particular importance. The simplest methods have been described above. Nevertheless the best preparation The tank is considered to be a propane tank. It can withstand almost any pressure. With its help, you can realize a strong flow without fear of damaging the structure.
To create a full-fledged tank from a propane cylinder, you will have to use welding. First, weld all the old holes and make two new ones: one at the bottom of the end, the second in its middle. Weld tubes with fittings to them.
You can use either collet adapters or couplings. The main thing is that this element of the design of a foam generator for washing, created by yourself, can withstand the pressure generated by the compressor.
For greater convenience, you can make a hatch on top of the foam generator. To make it convenient to refill washing liquid through it. The main thing is not to forget about the seal. The container must be completely sealed.
The lower fitting of the tank is connected directly to the compressor, the upper one is connected to the atomizer. As you can see, the principle of connecting a tank from a propane cylinder is the same as that of a sprayer. But the service life and reliability are many times higher.
How to save on materials
Firstly, it is not necessary to buy new components. Secondly, practice shows that half of the necessary spare parts for assembling a foam generator with your own hands can be found in the garage.
However, even a used compressor will cost at least 2-3 thousand rubles. But there is one trick here. This spare part can be removed from an old truck. On message boards on the Internet you can find hundreds of offers from tractor unit owners selling their vehicles for spare parts.
Compressor required power equipped with ZIL-130. Most of these cars have been sitting in junkyards for a long time. Therefore, you can take the part you need for a purely nominal fee to the guard, or even for free.
Please check the unit carefully before purchasing. There should be no oil leaks or other defects on it. Otherwise, working with the compressor is dangerous. Even if you manage to start a foam generator for washing, made by yourself, but equipped with a defective compressor, 1-2 cleanings and the unit will fail.
Important! Above we have already presented a way to make a net for bubbles with your own hands. Then a fishing line was used. With the same success, you can use a foam sponge or a polyethylene synthetic body washcloth.
Alternative methods for shaping the atomizer
If you don’t have fishing line, you can make a foam generator sprayer for washing with your own hands from a synthetic washcloth. Simply cut out the piece you need and place it in the tube. Make sure it is securely fastened. It is necessary that it does not crumple under strong pressure.
Important! Your main task when creating a sprayer is to securely fix the filter, which will create small bubbles with high density.
How to make your device more portable
The design of the foam generator for washing can be modernized. Naturally, all operations can be easily done with your own hands. In this case, you will need a small tank for the aerosol gun, as well as a nozzle for washing high pressure.
The pipe with the filler is replaced with a nozzle, and the propane tank with a tank for an aerosol gun (you can just as well use a sprayer). The weight of the structure is reduced many times. The installation of a welded frame and wheels makes the foam generator completely portable.
Results
Making your own foam generator for washing yourself takes time and effort. But the result completely pays for all the costs. Now every wash will be practically free for you.
Cheap home mini car washes have an insufficiently effective foam nozzle. As a result, even good non-contact foam does not cope well with dirt. You can improve the quality of cleaning your car by using a homemade foam generator. It copes with stubborn dirt, which can later be easily washed off with a mini-wash.
Materials:
- body from an old powder fire extinguisher with neck and lid;
- 1/2 inch steel tube;
- a piece of rubber from the chamber for the seal;
- garden hose;
- garden hose nozzle;
- ball valve 1/2 inch;
- quick-release adapter fitting to compressor M1/2 inches;
- fumlenta.
Homemade foam generator device
The foam generator is made using a meringue powder fire extinguisher or an old hand-held steel spray gun. You can use another metal container of 8-10 liters. It must be equipped with a neck with a threaded cap and a rubber seal.
A hole is made at the top end of the container for a 15 mm tube. It will be used to release foam. A short piece of pipe 7-10 cm is welded into it. A thread is cut on it to secure the adapter to the garden hose.
A hole for the tube is drilled at the side of the bottom of the cylinder. It will be used to supply air. A plugged pipe with side holes is inserted into it.
10 holes drilled in a row with a 2 mm drill are enough. The tube is welded so that they look up. Next, a thread is cut on it to secure the ball valve. The compressor hose fitting is screwed onto it. All threads are pre-sealed with fumlente or another method.
How to use
Fill the foam generator about halfway with water. Car shampoo is added to it for contactless washing. The tank is closed with a lid. A compressor is connected to the lower adapter.
A garden hose is connected to the top fitting.
Wide tube for spraying foam.
After turning on the compressor and opening the ball valve, the supplied air mixes the water, creating foam.
It rises to the top of the tank and, after it is filled, moves along the garden hose, splashing out onto the car.
A foam generator of this design works much better than many standard attachments for a mini-wash. It makes a thick foam, which, when using normal shampoo, allows you to wash even a very dirty car with minimum costs time and effort.
At the end, we wash everything off with water from a high-pressure washer or from a garden hose under normal pressure.
A foam generator is a device that produces and releases 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 one made by yourself, 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 being subject to corrosion, it is advisable to use stainless steel for this. Because he will have to deal with a lot 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 foam is unsuitable for use and does not have the necessary properties to get onto the car body in the required quantity.
- The composition enters a special “tablet”, where the final formation occurs. It creates not only the necessary 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. This is what makes it so popular. But to acquire this device, you don’t have to spend a lot of money, because you can easily assemble it with your own hands.
How to make a foam generator
Let's look at several ways to make a foam generator with your own hands. And let's start with the simplest.
- Of course, such a foam generator will not have the same effect as factory ones, but it will definitely not be superfluous in car washing. Prepare the following list of tools in advance: knife, grinder, spanners, 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 allow you to carefully create the desired spread and formation of foam. 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’s worth saying right away that two taps should be installed on it. Compressed air will be supplied through one hole, and the foam itself will be supplied 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 is immediately worth noting 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 circuit diagram. In reality, it is necessary to have a hose between the pipe and the tee for ease of use.
- The second method involves using it instead of a regular cylinder plastic canister. At first glance, it may 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 cross-section can be used. Instead of a washcloth, an ordinary fishing line is placed inside, and in a chaotic manner. You need to put a filter on one end of the pipe, and a special fitting for the hose on the other. You need to purchase several fittings.
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 foam generator as a test. This is necessary in order to identify all leaks and eliminate them before further use of the device.
The use of other foam containers is also possible. The main criterion is the ability of its walls to withstand sufficient air pressure. You need to take this seriously, as if the tank explodes you can get quite serious injuries. In addition, there is no need to use an overly powerful compressor if the cylinder capacity is insufficient.
By the way, a good foam sprayer can be considered a foam sponge, which has smaller sections and is best suited for creating a good and whipped foam.
Now you know how to assemble a good foam generator with your own hands. This will help you avoid unnecessary expenses on expensive equipment.

Contactless washing For many car owners it is a luxury, as it costs up to 300 rubles. Not everyone will allow themselves the next time they wash their car. Buy a mini-wash, spending up to 15 thousand rubles. Not many people solve it either.
But it is quite possible to afford a foam generator for washing with your own hands from a sprayer, spending minimal funds, by making it yourself from an old sprayer and a few simple parts. Such a foaming agent will provide constant, almost free, but fast and effective car washing at home.
Principle of operation
The main purpose of the foam generator is foam formation from shampoo and water, which after generation is evenly distributed over the surface.
The sprayer as a foam generator is based on mixing two foaming components under compressed air pressure and supplying foam to the surface.
In practice, this is achieved by mixing water and detergent in a container, compressed air forces the solution through a foam tablet to form a dense, active foam.

Necessary materials
For efficient work future foam generator, the purchase of expensive components, as well as the use of new parts and devices is not necessary. When making a device with your own hands, you will need the following parts and materials:
- container from a garden sprayer. Suitable containers for this include garden and vegetable garden sprayers, manual pump-type, garden comfort 12 l, Stanley pump-action, petrol garden backpack, manual pump-type, as well as the “Quasar” or “Beetle” models.
- For these models, the pump or pump is dismantled;
- pressure gauge with scale up to 10 atm;
- nipple with a shut-off valve that allows air to flow in one direction; two 0.5-inch fittings with four nuts and gaskets;
- valve that regulates the supply of foam;
- metal tube and nozzles for spraying water;
- reinforced hose that can withstand pressure up to 8 atmospheres;
- hose adapter;
- clamps for connecting fittings with hoses;
- foam tablet.
When selecting materials, the first step is to determine a container that can withstand pressure up to 6 atmospheres. Undamaged tank garden sprayer fits these requirements quite well. You can buy a foam tablet in a store or make it yourself.
The basis for the functioning of the foam generator from the Zhuk sprayer is a metal mesh, which is easy to make from metal brush, intended for washing dishes, or a tightly packed lump of fishing line.
Safety precautions
When making a foam generator, you need to take into account that the container in the sprayer can withstand pressure up to 4-5 atm. When pumping air into it, be sure to monitor the pressure gauge reading or control the pressure with the relief valve.
Do not use the device for other purposes than for its intended purpose by pouring toxic or flammable substances into the container.
How to make a foam generator from a sprayer with your own hands? If you have previously made your own auger for a snow blower, made a trailer for a walk-behind tractor, or assembled a cultivator or plow for a walk-behind tractor with your own hands, then it will not be difficult for you to make a foam generator yourself from a sprayer.
If the necessary parts and components are available, the foam generator is assembled in the following order:
- in a sprayer container hand pump removed and the holes are plugged;
- a pair of 1.27 cm (0.5 inch) squeegees are installed in the upper part of the tank. The parts are fastened with nuts on both sides, and their tightness is achieved using gaskets;
- A T-shaped adapter is placed on the air supply, a pressure gauge and a shut-off valve are placed on it, and a tube with a length slightly less than the height of the tank is attached inside. This is necessary so that air enters from below. Thanks to this, the liquid foams;
- the second drive is designed to release foam. A tap, a foam tablet are installed on it, and for quick connection of the hose, it is easily removed. A metal tube is connected to the hose, and a nozzle or sprayer is connected to it. The foam generator is ready.
To automatically adjust the pressure in the tank, it would not hurt to install fittings for air injection control in the form of a valve that releases excess atmosphere.
This will free the operator from constantly monitoring the pressure gauge when pumping air, and guarantees the safety of the device, eliminating the possibility of the tank exploding under pressure.

Motoblocks are necessary equipment from summer residents and farmers. get acquainted with the advantages of the Niva walk-behind tractor.
A home snow blower is a device with relatively low power for domestic use. The Husqvarna snow blower is what you need.
After checking the reliability of all connections and the tightness of the tank, water is poured into it through the neck in an amount of 2/3 of the total volume and concentrated shampoo is added according to the instructions (usually up to 2 g/l of water). The neck is securely tightened and the outlet valve is closed.
By pump or compressor through a shut-off valve pump air to the required pressure. The hose with the nozzle is directed to the surface for applying foam and the tap is slowly opened. The density of application can be adjusted using a nozzle or nozzle.
Conclusion
Self-assembly of a foam generator is quite simple and does not require special knowledge and skills. The cost of its production will be 10-15 times lower, than the factory device. To do this, you need to draw up a diagram of the product and a sequential action plan, as well as correctly select all the necessary materials.
When assembling the device, safety requirements must be taken into account: since the foam generator tank operates under pressure, its permissible value is controlled with a pressure gauge, and all parts and connections must be functional and reliably assembled.
