Do-it-yourself fume hood with a water curtain. W3000 water curtain spray booth

If you decide to do car repair, then you need to get a spray booth.

The safest and fastest way to purchase it is to contact the Ural Machine Tool Company in Yekaterinburg. Our experts will be able to quickly find the option that suits you at reasonable prices.

Of course, there is another way, but it is more complicated and, unfortunately, not entirely reliable.

We construct a water spray booth

Before starting work on equipping a spray booth in Yekaterinburg, it is necessary to sketch out sketches schematically, in which you will see a clear idea of ​​what basic elements the main structure consists of.

In general, the spray booth is a sealed box equipped with supply and exhaust ventilation. To create such a ventilation system, electric motors are used. The main part of the equipment includes a heating heating element, which allows you to maintain a high temperature throughout the entire painting process.

The camera must be equipped with lighting devices that allow obtaining uniform illumination throughout the entire area of ​​the box.

For a small amount of work, a private garage can be used as a box. If there is none, you can organize a small building, which, of course, will entail additional financial costs.

Manufacturing

After designing a spray booth with a water curtain, the next step is the technical calculations. They must be carried out with scrupulous accuracy, as incorrect calculations can lead to defective equipment functioning.

An approximate diagram of the camera arrangement is as follows:

• Door installation. They must be sealed and insulated.
• The floor structure consists of an opening and a pipe that extends outward for air outflow.
• The walls are insulated and sheathed with corrugated board.
• The air exchange system includes metal pipes and two electric motors.
• Insulated ceiling, made of corrugated board. A metal grill is installed in the ceiling for air flow.
• Air purification is carried out thanks to a three-level filtration system.
• Lighting is provided by ceiling and side lights.

Spray booth with water curtain »> An excellent business solution is to paint cars at home. But in order to be able to paint cars, there is little experience and equipment for painting, it is also necessary to have a room in which the painting of vehicles will be carried out. In organizations that are engaged in painting cars, they have long been doing paintwork in a booth with a water curtain. It is no secret that such a device can be made with your own hands, only with some effort and spending a small amount of money to buy some equipment. You can buy a ready-made one, only its cost will be very high, and not everyone is ready to invest a large amount. In order to make a device with a water curtain with your own hands, you will also need some knowledge.

The spray booth with a water curtain is a closed room made of stainless steel and equipped with supply and exhaust ventilation. Such ventilation is created using electric motors. The main part of the device is a heating heating element, which helps to heat the room to the required temperature and maintain it during painting work. The camera also includes lighting, which must be evenly distributed over the entire area, and have a sufficient luminous flux. It is best to place them not only on the ceiling of the room, but also on the side walls. The device also includes equipment for painting and other auxiliary tools.

Layout of the painting booth

Knowing what the spray booth consists of, it is necessary to decide on the location, where the arrangement will be carried out, and to make a project on the location of the main structural elements. A garage can serve as an excellent location for the construction of a device, or build a new extension, which will take more time and, accordingly, finances. To make a device with your own hands, you will need structural elements from which it will be based, heating and ventilation, filtration and lighting systems.

Making a painting chamber

Having made the layout, it is necessary to carry out all the technical calculations and proceed with the installation work.
First of all, a new room is built or a frame is assembled inside the garage. Overall dimensions should be: length 10 meters, width 8 meters, height 3.5 meters. The spray booth is respectively 4 meters wide and 6 meters long.

1. 1. Gate installation.
      It is best to use the insulated gates so that there is no leakage and loss of warm air, the outside is sheathed with corrugated board. At the point of contact of the gate, it is insulated with a special adhesive tape. Places with cracks must be covered with polyurethane foam.
   2. Floor construction. The base of the floor is made of concrete, inside of which a hole is made, and a metal pipe with a diameter of 150 mm is brought out to the street for air outflow. A metal grate is laid on the floor over the entire surface of the room to a height of 15-20 cm.
   3. Walls. The walls are sheathed with corrugated board, and inside they are insulated, you can make a sandwich panel.
   4. Air exchange system. Components: two electric motors and metal pipes with diameters of 100 mm and 150 mm, respectively. For supply ventilation, an electric motor with a power of 5 kW is used, for exhaust ventilation at least 7 kW.
   5. Ceiling. It is made of corrugated board, with insulation. A metal frame is installed in the ceiling for air flow. The electric heater, which will supply warm air to the room, is installed outside.

1. Air cleaning. It is carried out with the help of filters and has three levels of cleaning.
   • Level 1. A frontal water curtain is created, which is carried out by flowing down uniform streams of water;
   • Level 2. Cleaning the air inside the device. Promotes filtration and air purification from paint waste;
   • Level 3. Dry filtration. Contributes to the complete cleaning of air from paint particles and performs the function of protecting the fan from paint adhesion.
2. Lighting. LED or fluorescent lamps are mounted on the ceiling and walls of the room.
   Automatic sensors for control and monitoring of the system of supply and exhaust fans and filters are also installed.
   After assembling everything necessary for the water chamber, the painting equipment is installed.

How the work is done

The electric air heater pumps air from the atmosphere into the closed space of the room. Passing through the system, the air is purified by filters, each of which provides a certain purification.
The temperature rises in the room due to the work of the Ten. The painting process begins. Below on the floor, air from the chamber begins to be sucked out using an exhaust fan. Water curtains are installed in front of the main line, which help to retain paint particles. Here, the air goes through all three levels of cleaning, if any. Factory-made water-curtain cameras work in the same way.

The positive aspects of the device with your own hands

1. Free planning of the system.
2. Great cost savings.
3. The ability to save money on all components.
4. The ability to use the main parts of the structure.

Disadvantages of the device

1. There may be inaccuracies in the calculations, or imperfections in the installation of the device.
2. There is no way to completely automate the process, since the elements of the device consist of separate parts.
3. There are no guarantees for the performance of such a device.

Price

The cost of building a camera with a water curtain with your own hands can take a long time, but its cost will be about $ 4,000. You can buy a factory one from $ 20,000 and above. To start a business, the best option is to build it yourself, which is much more profitable for a starting business.

There is little pleasant in the fact that cold air penetrates into a warm room, cooling it, because in this case it turns out that the street is heated. Not only does this create uncomfortable conditions, it also noticeably affects health and wallet. This problem can be overcome by using a thermal curtain, which is a reliable barrier between indoor and outdoor air.

They differ in the source of heat, that is, such equipment can be electrical and water. The water heat curtain benefits from economic efficiency, since the heating element is hot water. However, this type of device, like the other, has excellent advantages, due to which it is becoming more and more popular:

1. Protecting the building from heat loss.
2. Protection against cold air, which, thanks to the curtain, cannot enter the room.
3. Creation of a barrier that does not allow exhaust gases, dust and insects to enter from the street.
4. Equalization of the temperature gradient.
5. Draft protection, which has a positive effect on health.
6. Additional heating of the room.
7. The ability to keep the door open.
8. The ability to create coolness in hot weather.
9. Efficiency due to both less heat loss and the fact that the source of energy is not electricity, but water.

Working principle and installation

The principle of operation is quite simple: a powerful fan creates a high-speed air flow, which forms an "invisible barrier", thanks to such a system, warm air cannot leave the room, but cold air can penetrate into it. The heat source of the water curtain is hot water. It turns out that for the operation of the water-type device, central heating is needed.

Installing such equipment is, of course, difficult, but this cannot be compared with the fact that during operation the overhead costs are low, and the power is very high. The area of ​​application of water curtains mostly extends to industrial buildings that have large openings. The device is indispensable in restaurants, shops and warehouses, that is, those in those places where the doors are opened very often due to the large flow of people.

Installation is usually done above the door. Installation above the opening means that the curtain is horizontal and to the side of the opening it is vertical. It should be remembered that the vertical curtain must be at least ¾ of the height of the opening to be protected. This is the only difference between this type of device and the horizontal one.

Main element

The main design element is a radial fan, which is necessary to create the required air flow. Such a turbine should be uniform and located along the entire length of the device. It helps to create an even flow. The engine is mounted on the side of it.

However, manufacturers often choose to center the engine with small turbines on either side. The reason for this arrangement of elements is the complexity of manufacturing a turbine with a length exceeding 800 mm. How effective is this installation method? Of course, such a simplified curtain will cost less, but there will be a "dip" in the central part of the air flow, which significantly reduces the protective properties. In addition, the heating elements will be blown unevenly, and this leads to their earlier breakdown.

How is the water curtain controlled?

The water curtain is accompanied by at least two switches, one of which must turn on the fan, and the other must turn on the heating elements. Heating power regulators can also be installed, which have two or three stages. Fans can be two-speed. The air curtain can have a thermostat that turns off the device or heating elements when the set temperature is reached.

There is a built-in and wired control panel, it all depends on the chosen model. However, the built-in type is used on curtains that are small in size, which are installed for windows and doors. This is because the distance depends on the ability to reach the buttons. Accordingly, for water curtains, it is more rational to use remote controls that can be installed in the right place.

Sometimes the use of a limit switch takes place, which is convenient in that it turns on the device only when the gate is open. It turns out that the switch starts to work when the doors or gates are opened. Its use is very convenient in warehouses and hangars.

Curtain selection

The choice of an air curtain is influenced by the following factors:

1. Device length.
2. Power.
3. Performance.
4. Type of instalation.
5. Control method.

We have already discussed the last two factors, now we will talk about the other three.

1. Performance. It is on it that the air flow rate and the installation height depend. For example, let's take a doorway that is about one meter wide and about two meters high. In this case, the "pumping" of the curtain should be from 700 to 900 cubic meters per hour. With such a performance, the air flow rate will be about 8 meters per second at the outlet of the device, and about 2 meters per second at floor level. Of course, the price of such devices is not small, therefore, devices with lower performance are used to protect small openings. Since water curtains are used more for industrial buildings, it is impossible to save on this factor, otherwise the efficiency will be minimal.
2. Power is also an important factor when you consider that the equipment can heat the air in the room, although this factor is not necessary at all. For example, let's take a 10 square meter building that is not heated and has a ceiling height of about three meters. The power required under such conditions is 1 kW. However, in this case, the building must be capital, that is, the ceiling and walls must have good thermal insulation. You should not choose a device with a high power for well-heated places, or even a device without a heating function. It is worth mentioning the peculiarity of the heating function: at the outlet of the curtain, the air will never be hot, even if the power is maximum, it will only be warm. There is an explanation for this: the heating elements have a high blowing speed.
3. Length. It can be from 600 to 2000 millimeters. Lengths from 800 to 1000 millimeters are very popular, such devices are installed above a standard opening, therefore they are not suitable for industrial facilities, where water curtains are often used. How to correctly calculate the length in this case? It should be the same as the width of the opening or slightly more. This is important in order for the air flow to completely block the opening and prevent cold air from entering the room.

All this information will help you choose the right water curtain, as it plays an important role in creating a comfortable environment. The installation of such equipment will indicate that caring for people is an integral part of any organization.

. on the organization of the supply of painted products, ─ to dead-ends and checkpoints. For individual production, dead-end spraying booths of periodic action are more often used, and for large-scale production, walk-through spraying booths.

. paint booths can be open and closed (open and closed). Closed spray booths provide complete isolation of the work area from the surrounding area. This allows, due to the coordinated operation of the supply and exhaust ventilation, to maintain a pressure inside the chamber that is different from atmospheric, thereby preventing uncontrolled emission of contaminants. The body of an open spray booth forms a partially enclosed space. The number of openings depends on the painting technology, the location of the workplace (outside the chamber or in the chamber) and the method of loading and unloading the products to be painted.

. features of the filtration system give reason to distinguish two large classes of spray booths ─ dry spray booths and chambers with hydrofilter.

Chambers with a water curtain in regulatory documents

How important, and often necessary, a spray booth with hydraulic filters or a spray booth with a water curtain is stated in a number of current regulatory documents.

“The air sucked out of the painting chambers, the cabins of the floor grilles is purified from the resulting aerosol of the paint and varnish material. Cleaning should be carried out, as a rule, by the "wet" method in hydro-filters. " This provision contains “Sanitary Rules for Painting with Hand Sprayers. Sanitary and hygienic characteristics of working conditions " .

Resolution of the Ministry of Labor of the Russian Federation of 05/10/2001 No. 37 "On the approval of the Interindustry rules on labor protection during painting works" even more categorical. Clause 3.52 .: "Exhaust air from the premises for work with paintwork materials, local ventilation systems and local suction must be cleaned from aerosols of paintwork materials using the" wet "method in hydro filters."

Not only the sanitary and hygienic aspect is important, but also the fire safety requirements. "PPBO-109-92. Fire safety rules for railway transport " : “Painting works by spraying paint and varnish materials should be carried out in painting booths made of non-combustible materials and equipped with hydro filters. It is not allowed to operate the local suction system of painting cabinets, chambers and booths without hydraulic filters or other effective devices for capturing aerosols of combustible paints and varnishes. "

Color is very important

Painting booths are a relatively young type of equipment, in contrast to paints or varnish-and-paint materials (LKM), which mankind has been using for more than tens of thousands of years.

At least, the most ancient of the rock paintings are of this age, for the application of which they used mineral powders, charcoal, lime, clay, and later animal fats, the secret of the glands of living beings and other biomaterials. The chemical industry has expanded this arsenal with a variety of synthetic paint compounds that have made the world much brighter. Of course, the brightness of the sky, water, minerals and plants remained the same, but the noosphere (or anthroposphere) played with all the colors of the rainbow. It happened yet. and because color, being an integral part of design, has become one of the most important tools for promoting many products, incl. industrial products. In addition, the thin layer of paint has become economically important, protecting millions of tons of steel products and structures from corrosion.

How important color is, and therefore painting equipment in general and spray booths in particular, can be judged by the example of the automotive industry and the huge, hundreds of thousands of jobs-creating car service industry. For them, the quality and cost of painting are one of the main trump cards in the competition, and the functionality of the spray booths largely determines the economic efficiency of production.

Prerequisites for the appearance of spray booths

formed in the second half of the 19th century... In 1887, a spray paint method was invented in the United States. (This, by the way, stimulated the appearance of paintwork materials with unprecedented properties, for example, quick-drying). Furniture manufacturers were the first to adopt the new technology ... But soon, and on a much larger scale, it began to be used in the rapidly gaining momentum of the automotive industry.

The interest in spray painting on the part of many industries has given a powerful impetus to the development of enterprises producing such devices. But at the same time, he clearly set before them the task of providing acceptable working conditions for the personnel operating them. The answer to these challenges was painting chambers, with the help of which it was possible to localize the influence of paint fragments not fixed on the painted surface ─ the so-called. "Colorful fog". Mists, as a rule, are called aerosols, the dispersed phase of which is represented by liquid droplets ... Of course, the contaminants accompanying the staining process, often very toxic, are not limited to fogs, ─ it is enough to recall such a component of them as solvent vapors.

Already at the beginning of the 20th century, tools such as an orderly air circulation system and air-purifying filters were involved in the implementation of an innovative technological concept for that time. As much as they look like modern spray booths captured in photographs from the first half of the 20th century, they have changed a lot. Because as a result of scientific and technological progress, dry and hydraulic filters, fans, pumps, equipment for applying paintwork materials and paintwork materials themselves have changed (just remember the powder coatings, for the application of which powder paint booths are used).

The range of tasks solved with the help of spray booths has expanded. As in the beginning of their existence, they help to minimize the harmful effects of paints and varnishes on the health of workers , only today against the background of stricter and more detailed regulations of national legislation in the field of labor protection. To this was added another important task, which at the beginning of the 20th century was not yet so acute, ─ reducing the burden on the environment .

And of course, the use of spray booths allows ensure modern painting quality standards , thanks to supply air filtration systems that remove even the finest dust. And by automating technological processes and increasing energy efficiency, it is possible to increase work productivity and make the dyeing process more economical.

Water spray booths successfully cope with these tasks. They are easy to use, since the presence of hydraulic filters simplifies the cleaning of fans, filters, pipelines and air ducts from paintwork particles. The presence of water improves fire safety, minimizes the possibility of increased concentration of explosive substances. Water curtains with high efficiency clean the air polluted in the working (painting) area from solid particles of paint and glue, solvent vapors, aerosols and other contaminants.

How any spray booth works is to create a directed air flow... Outside air enters the work area. The quality of staining will be the higher, the better it is prepared, ─ with the help of filters it is cleaned of solid inclusions, has the required temperature and humidity. Already in "waste" form, contaminated in the working area as a result of contact with paintwork materials, it is cleaned by exhaust ventilation filters and discharged into the environment.

If some of this work is done by hydro filters, such devices are called water spray booths or water curtain booths. “Part of the job” ─ because the presence of hydrofilters does not preclude the use of dry filters working together with them, usually located in front of the exhaust fan of the final fine filters.

Hydrofilters

Since the basis for the allocation of spray booths with a water curtain, in a separate class of equipment, was the use of hydro filters, they (hydro filters) have earned the full right to be presented first when considering the device of such chambers.

The term " hydrofilter »In this case means an air filter that purifies the air using water as a filter material. The disclaimer "in this case" is due to the fact that sometimes hydraulic filters are called hydraulic filters, that is, filters used to purify fluids in hydraulic systems.

The use of hydro-air filters is not a spray booth monopoly. They are, for example, installed in ventilation systems for air cooling, protection against sparks, removal of soot, soot, grease, and removal of extraneous odors.

Common to all hydrofilters ─ the purification of polluted air occurs when it interacts with water. Depending on the design, screen (cascade), nozzle and nozzleless hydraulic filters are distinguished. They differ in the principle of supplying air-purifying water and, as a result, in the peculiarities of their work.

In screen hydro filters, water curtains are created using overflow water distribution devices and shields. In spray nozzles, nozzles are used to form water curtains.

Pumping and non-pumping bubbling-vortex hydrofilters are also used, in which the air is purified as a result of its active mixing with water. Their name comes from the French barbotage - stirring. The principle of operation is the passing of gas or vapor (in our case, air) through a layer of liquid (in our case, water).

In a screen hydrofilter, an air flow containing particles of paintwork materials and solvent vapors is supplied to a screen covered with a continuous layer of water flowing down it, the circulation of which is ensured by the operation of the pump. Having collided with water, large particles lose their speed and together with it flow down into the bath located under the screen. Contaminants that have overcome this barrier are removed when the air flow passes through the water curtains located behind the screen. A droplet separator that can “handle” vertical and cross currents helps to make the air cleaner.

Side curtains can be installed along with front curtains. An active water floor (or an active water sump) - a bathtub covered with a grate, possibly buried in the concrete floor of the workshop - provides more efficient trapping of the ink mist.

In nozzle hydro filters, water is sprayed using nozzles. Typically screwed or tangential with a hole diameter of a few mm.

Screw nozzles form a more stable flame, but tangential nozzles are easier to manufacture and less likely to clog. The spacing of the nozzles is set depending on the angle of the cone of the jet (usually 70-75º) and the effective length of the flame.

A sheet steel or plastic shield installed between the nozzle rows helps to create a directed air flow, preventing it from entering between the water torches.

The flow rate of water depends on the speed of its flow along the inclined shields or screen, as well as the number of curtains and their cross-sectional area (i.e., the thickness of the water layer, which is usually several mm). The water circulation is almost closed. Almost ─ because, due to losses due to evaporation and disposal of especially polluted waters, its supply has to be periodically renewed. The sludge of the spray booths with a water curtain is accumulated by a special water purification system from paint and varnish waste.

In order to prevent water constantly in motion from foaming, antifoam additives are added to it.

The case is “classic” and not quite

An obligatory attribute of a spray booth is a body. It is not always a "classic" enclosure with a floor, walls and a roof. It can consist of only one front wall. There are tubeless technologies for applying paintwork materials, used, for example, for painting large-format products. And in many of these devices, the air is purified using hydro filters. They can have different designs. For example, tubeless installations with bottom suction, consisting of a hydraulic filter, an exhaust ventilation system and a pumping unit. For painting vertical surfaces, lifting platforms equipped with a hydraulic filter are used, ─ air contaminated with paintwork materials is drawn into the gap formed by the surface to be painted and the wall of the hydraulic filter of such a platform.

Side walls and a roof help to create a directed air flow and prevent contamination from the spray booths located nearby from entering the workspace.

Spray booth housings can be solid or modular. The most common material for their manufacture is sheets (panels) of galvanized or stainless steel with a thickness of 0.8-1.5 mm. There is an experience of using plastic with a release coating, with a thickness of 10 mm or more. The advantages of this solution are that paint residues are less likely to adhere to the camera surfaces and are easier to remove.

The dimensions of the spray booths are determined by the organization of work and the size of the products for which they are intended to be painted. Organization of work ─ is where, ─ inside or outside the chamber, ─ is the workplace located, whether it is necessary to rotate the products during the painting process, whether overhead conveyors with a swing amplitude are used for their transportation, etc.

Ventilation system

The ventilation system provides the required direction of movement and the uniformity of the flow of exhaust air to be cleaned ─ from the working area to the hydraulic filter.

Usually, centrifugal and axial fans of medium and low pressure are used, the parameters of which are determined based on the amount of air that must be removed from the spray booth per unit of time. The fan can be installed on its roof. But at the same time, especially in the case of powerful and "revolving" fans, it is necessary to prevent noise and vibration impact on the camera body.

In an open spray booth, all or most of the clean air enters through open openings directly from the workshop, and its lack in the room is compensated by the workshop supply ventilation. To increase the amount of air used by the spray booth, an air inlet pipe equipped with a valve that opens when the spray booth is in operation can be used. This is true for spray booths located in small spaces.

Trends in the development of painting technologies used in mechanical engineering, woodworking, the production of building and other metal structures ─ wherever spray booths with water curtains are used ─ are determined by the progressive tightening of requirements for environmental protection and sanitary and hygienic requirements, as the most important segment of labor protection. And also the need to increase economic efficiency by increasing labor productivity, energy and resource conservation, improving the quality of work.

They can be met by increasing the efficiency of filters, using new construction materials, energy-saving ventilation and pumping equipment, increasing automation and robotization of technological processes. This means that spray booths with water curtains have to change. More in content than in form. However, this is exactly what they have been doing for many decades.

Do-it-yourself car painting is a responsible procedure that requires compliance with a number of conditions. A specialized camera for painting a car with your own hands - this option is now chosen by many motorists. Buying such an object will not be cheap, so some people prefer to independently provide what the spray booth requires with their own hands - drawings, materials, assembly.

Painting a car in this way has a number of serious advantages over using a spray gun in your own garage. Due to the tightness, you do not have to worry about foreign particles of dust and dirt getting on the painted surface.

In addition, the design excludes the occurrence of unwanted air turbulence, due to which the enamel will not lay down on the surface of sufficient quality, streaks, pimples and other defects are formed.

DIY car painting

Do-it-yourself paintbrush is profitable, but you have to work hard to build it. With a competent approach and a conscientious attitude to work, you will be able to independently build a camera for painting a car, which will help avoid serious financial expenses and organize everything to your liking. Below we will look at how to make a spray booth with your own hands, and what steps are needed for this.

First stage

Before you build a spray booth with your own hands, you must imagine how it will look and prepare everything you need. Draw on paper a project where the future paint booth will be shown to scale along with all the nodes:

• premises;
• heat generator;
• heat gun;
• ventilation system.

These are the main items, each of which includes many smaller elements - doors, insulation, lighting system, etc.

Room for the spray booth

Let's talk about the room

Before you make a spray booth with your own hands, you are looking for a suitable room. It can be a metal garage or a large workshop - the main thing is that you have the space and the ability to equip everything accordingly.

A car painting booth must have walls that will meet a number of requirements:

• fire resistance;
• tightness;
• the ability to periodically wash;
• the presence of thermal insulation.

The last point is especially important when it comes to a garage with steel walls - you have to make them double and put an interlayer of basalt wool or other fireproof heat-insulating material.

The room must be airtight

Be sure to pay attention to the floor - it should allow air to circulate unhindered. For this purpose, make the covering in the form of a multilayer grid - this way the bottom will ensure a normal exhaust and flow of air.

Two doors are a mandatory requirement for fire safety. They must be easy to open to allow for emergency evacuation in the event of a fire, and sealed to prevent dust and debris from entering the room.

The dimensions of the chamber must be sufficient so that the master during the work does not have obstacles to free movement. A concrete or metal frame can be selected as a base. An exhaust mechanism with filters and valves is arranged under the floor surface. Consider the need for walkways to move.

Lighting is important

In the process of painting cars with your own hands, one of the very important roles is played by the lighting of the room. It is necessary that it be bright enough, comfortable for the eyes, does not give shadows and glare.

Practice shows that the most convenient option will be fluorescent fluorescent lamps - they are placed on the ceiling. To provide a sufficient view of the lower part of the machine, several elongated light sources are hung along the walls.

Fluorescent fluorescent lamps

An equally effective solution to the lighting problem will be LED lamps. This type of lighting is becoming more and more popular due to a number of advantages that LEDs have over other options:

• bright high-quality lighting;
• minimum energy consumption;
• low operating temperature;
• reliability;
• durability

Today, you can install LED lighting indoors without any problems - it will cost a little more, but the result is worth it.

Without providing high-quality lighting, you will not be able to fully control the painting process, which will negatively affect the final result of the work.

Proper lighting in the spray booth

Room ventilation, air purification and drying

Do-it-yourself paintwork is built taking into account all the requirements of painting technology and safety. Well-designed air ventilation occupies a key position here. She is responsible for purifying the air, as well as ensuring that the mist of paint is properly deposited and removed.

Depending on which principle is used in the ventilation system of the room, two types of cameras are distinguished:

• with one motor;
• with two motors.

In the first case, air is supplied into the room from above, and the fog settles down - the necessary pressure is applied to it. At the end, it is withdrawn through an individual channel set up for this purpose. In the second case, one of the motors pumps air, the second sucks it out, taking it out of the chamber.

Painting booth ventilation

The design will need high-performance ceiling air filters in order to exclude the possibility of foreign particles entering the painting area. For this purpose, it is recommended to choose air filters operating in a two-phase mode - in the first phase, large types of contaminants are removed, in the second, small ones. It is important to take into account that it is necessary to clean both incoming and outgoing air flows. Filters installed underneath will clog faster and will have to be replaced much more frequently.

The installation of filters should provide for the possibility of turbulence in the air flow with enamel particles - for this you need to correctly position them around the perimeter of the room and take into account the air pressure.

After painting, the car will need to be dried - for this, a special device is arranged. As a drying, a heat generator is used, which operates on an advantageous type of fuel. Some people use infrared heaters for this purpose. The main requirement for drying is an even supply of heat to avoid overheating.

Supply and exhaust ventilation in the spray booth

Some more useful information

For interior decoration, use non-flammable materials such as metal. You should not choose such an option as lining, since the danger of fire increases. Depending on how correctly the finishing work is carried out, it will be possible to assess the degree of tightness, which is important in order to avoid the ingress of dust and foreign particles. Choose smooth, easy-to-clean surfaces to make cleaning easier.

Think about the premises where inventory, paints, professional equipment, safety equipment, overalls will be stored.

The work of painting a car is simplified by the presence of automatic process control. This, of course, will affect the cost of the entire project, but, on the other hand, you will receive a number of invaluable benefits. The automatic control panel must have a panel made of durable, reliable material. It should be easy to use, ergonomic and comfortable. Consider switching quickly between manual and automatic modes.

Conclusion

Building a specialized paint booth for a car is a laborious process that requires a lot of effort and energy. You will have to monitor information about existing options and, based on them, come up with your own project - you can take any ready-made solution as a basis.

The process of working on the implementation of a project is difficult, but interesting - here you can apply your creativity, imagination and ability to cope with difficulties.
