The most pressing problem with paint booths is the accumulation of mist from fine paint particles inside the room. These elements can negatively affect human health. In order to eliminate these particles, it is necessary to install a filter for the spray booth. It is this that will ensure the free movement of air masses and clean them of pollution.

Filters for spray booths are in most cases made of polyester fiber or corrugated cardboard. These elements can be located on the floor or on the floor. Depending on the level of indoor air pollution, it is recommended to change them at least 1-2 times throughout the year.

Functions of the ventilation system

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline!

Filters for spray booths perform a very important function. They are capable of trapping particles different sizes contained in the air. Small elements of this type may appear in the form of dust or small debris.

High-quality air filtration inside the paint booth is very important at the final stage of painting, when forced drying of the applied layer is carried out. Through its actions, the ventilation system prevents small particles from getting onto the surface to be painted.

Filtering stages

The spray booth filter provides three levels of air purification from small particles. Thus, polluted air initially enters the ventilation system. Here it is cleaned from the content of unnecessary elements and already in pure form air masses return inside the spray booth.

Types of filters for spray booths

Filters for spray booths are positioned as the main elements for capturing aerosol particles. They can have a single or dual motor design. Depending on the installation method, such devices are either floor or ceiling.

Ceiling filters

In this case, it is most advisable to use a roll filter material that can cover the entire ceiling surface. It is capable of passing through itself air masses entering the chamber. Fibrous structures are used as a filter base, which are pre-treated with special compounds.

Floor filters

Floor filters for spray booths can also be presented in the form roll material with increased fire resistance. Alternative option in this case the filter is of inertial type. The operation of such a device is based on the principle of mechanical separation of large dust particles with a subsequent change in the direction of air flows. This variation of floor-standing devices has many advantages:

• the ability to purify large volumes of air;
• high quality cleaning;
• reliable operation of the entire system;
• maximum cleaning speed.

It should be noted that this device does not do a very good job of filtering particles that are too small. In this context, installing an additional filter is a vital necessity.

DIY filtration system

At self-installation cleaning system, it is recommended to install ventilation inlet filters and additional ceiling filters. Only this approach can ensure the most positive result.

When installing the system yourself, you must also take care of installing cassette dust collectors. Such a need may arise if the ventilation operates in recirculation mode.

Another good way installations ventilation system with your own hands - implementation of the “wet floor” method. In this case, dust and paint residues enter the flowing stream of water and are removed along with it into the sewer. In this case, you should first take care to prevent splashes from getting on the surface to be painted.

To ensure safe work in the painting booth and at the output to obtain high quality applied coatings in such structures, a dry air filtration system is used. By removing and filtering harmful fumes and residual paint particles, you will ensure high level fire safety and environmental friendliness. And even if the system has filtration in the form of a water curtain, in any case you will not be able to refuse dry filters for the spray booth. We will talk about their features and types in this article.

The main task of filtering

Filter system various types designed to clean the air entering the painting booth, or contaminated air masses that are discharged outside. These structural elements are capable of capturing various dust compounds, removing paint residues, and retaining harmful substances.

Here are the particles that interfere with work, which are removed using filters:

• dust and small particles of debris. They come mainly from outside air intake. As a result, when it comes into contact with a painted body or part, it forms areas with defects in the coating.
• paint and solvent residues. Fine dust from paint and solvents, also with the help of air pressure inside the chamber, is usually removed into floor channels, where it settles on special filters.
• harmful fumes, including from solvents. They are dangerous to the human body and must be removed from the work area.

Even during the drying process, it is important that absolutely clean heated air enters the chamber, otherwise dust or dirt particles falling on the surface of the car body will ruin it appearance, and will lead to the formation of defects.

Filtration scheme in the spray booth

The entire system can be divided according to purpose:

• preliminary air purification.
• basic filtration.
• fine air purification.

The first two types are mainly used. Elements installed in various places of the camera are responsible for their implementation. Let's look at them in more detail.

Pre-cleaning system

Its main task is:

• cleaning the supply air entering the chamber.
• repeated purification of the air mass if the system provides recirculation. In this case, the air, after cleaning, enters the work area again.

This filtration unit can consist of pleated or cellular air filters for spray booths, which are mounted in front of the fan. The second type is pocket filters that perform rough air purification. The required accuracy class of the purified material during coarse filtration varies in the range G2 - G4. Coarse filters include cardboard (paper) labyrinth filters for paint booths, which have different shape, and replacing them will not greatly impact the budget for camera maintenance.

Basic filtering

This is the process of elimination harmful substances from the work area while the painter is working, or while the car is drying.

Most modern spray booths come with either a ceiling filter (single motor designs) or a ceiling and floor filter (dual motor designs). These two types of ventilation systems differ in the principle of removal and filtration of air masses.

1. Single-motor systems operate on the principle of permanent fence fresh air from external environment, which is supplied from ceiling ventilation systems. Due to this, a pressure difference is formed and clouds of dust from paint and solvents are pressed against floor covering, in which there are channels for outputting it outside. This approach is harmful to the environment and is only possible if the painting line is lightly loaded.
2. The dual-motor system also supplies clean air through ceiling structure, but already removes it with the help of fans running in the floor, after passing it through filters, for example, carbon type. These filters are installed in filter boxes of domestic and industrial ventilation systems and serve to 100% remove odors, toxic gases, chemical vapors, and gaseous pollutants from the incoming air. They provide the necessary sanitary and hygienic standards. Also filters with activated carbon are used in growbox systems (hydroponics), industrial hoods.

Filters must be placed over the entire area of ​​the chamber.

Ceiling filters

Materials in rolls are used as ceiling filters. They are already the second link in the purification of incoming clean air and have a cleaning accuracy class of F5 - F6.

The filter itself is fibrous material, treated with anti-fire impregnation.

Floor filters

It is filters installed on the floor that are subject to the greatest contamination. They are subject to cleaning accuracy class G4.

There are two main types:

• rolled materials such as fiberglass and others.
• inertial type. It works on the principle of mechanical filtration of large solid particles during sudden changes in the direction of air flow. This type of element is excellent for removing large volumes of heavily polluted air, but does not cope well with filtering small particles.

If you organize these two filtration systems correctly, then you can forget about the frequent replacement of fine filters, which are additional large-volume pocket filters and are mounted in the air duct. Also often used are cassette panels at the outlet of the air duct, or folded cellular panels for fine aerosols inside the air duct. The cleaning accuracy class of such systems is F5-F9.

If you are making a filtration system yourself...

The minimum set when designing an air purification system in a paint booth is coarse filters and a ceiling filter with a system for removing contaminated air masses in the floor.

In cases with single-engine designs, some craftsmen organize a “wet floor” system, the essence of which is that there is a running water, and after dust, paint and harmful vapors enter it, it is discharged into the sewer system. In drying mode this type filtration is not used, and the humidity in the room may be high.

Be sure to maintain a filter replacement schedule according to the parameters specified by the camera manufacturer.

How do you filter the air in your paint booth? We are waiting for answers in the comments below.
