The most important thing when arranging a spray booth is the presence of a good hood itself. It is she who will help in a timely manner in a short time to remove from the room all the toxic fumes that appear after using the paint. In addition, it is worth paying attention to the fact that it is when using the ventilation system that all kinds of dust, rather small abrasive particles, are removed from the room without any problems. All this remains in the air after processing the car and preparing it for painting.
It is worth paying attention to the fact that if a car is being painted on the territory of the garage, then the room must meet sanitary and hygienic requirements. In other words, the hood in the garage must be. Please note that it is possible to build a hood with your own hands. You don't need a lot of money for this. Everyone drew attention to the fact that in the territory of such a room as a garage there is always a very large amount of dust. It is worth noting that you will not be able to paint a car in such a room. The thing is that a modern hood must be installed in the room, in which there are installed valves, filters and air-type pumps. This kind of ventilation of the spray booth has the main task, it consists in removing the spray mist and venting gases from the booth where the car is painted.
Please note that simple ventilation for a garage where vehicles are painted will not work. She simply will not be able to cope with the task that is assigned to her. Before starting the setup, the spray booth hood must fit well with existing or future ventilation.
Composition of the required system
On the territory of any garage in which it is planned to paint a car, there must be special ventilation. It is with its presence that all toxins will be removed from the room in a short time, which can be harmful to the human body during work. Its arrangement can be done with your own hands. But, despite this, you will need to make a certain calculation. Homemade ventilation in a spray booth, made by hand, is not very simple in its scheme. So, first of all, on the territory of the garage, it is necessary to make a calculation where a fan should be installed designed to remove air from the room.
But before polluted air enters the normal environment, it must be cleaned. In large enterprises, it is for this purpose that special filters are installed. In the event that you are installing in a garage, where you plan to paint a car with your own hands, then you can install a filter for mechanical cleaning. You will not need a share of this, asks a specialist. This element is easy to make, you just need to use a small piece of foam rubber or synthetic fabric.
It is worth paying attention to the fact that only one outlet of polluted air will be very small. Therefore, creating a camera in the garage for painting a car, it must be equipped so that fresh air is supplied to the room. In other words, you need to make sure that there is fresh ventilation in the garage. As a rule, the air that the system discharges to the outside must be compensated for with clean air.This can be done by a supply fan, which has a built-in mechanical filter, which prevents all kinds of debris from getting into it. In addition, for the normal operation of the system, it will be necessary to make the correct calculation of where the fans should be built. For such a paint brushes, there must be a lot of ventilation ducts.
To create such a system, you will need to purchase stainless steel pipes, or sewer pipes may be perfect.
How to calculate
First of all, before installing ventilation, you will need to calculate how well the air exchange in the garage is performed. So, for this you need to know a few rules. Knowing them, you can make a calculation without any problems.
- You will need to know the slowest speed at which air moves through the pipes. It should not exceed 25 cm per second.
- There is no hope for natural ventilation. Her work in such a room will not be felt.
- You will need to constantly monitor how well dust is removed from the garage.
- It is recommended that in the garage where the car is painted there is a timer for turning on the ventilation.
Necessary equipment
So, after the calculation of where the hood for the spray booth will be installed, you will need to think about purchasing fans. They are the main investment of funds. You also have a great opportunity to reorganize air intake pumps, fans, which are used for household ventilation schemes, with your own hands.
Please note that a special device in the paint room that ventilates the room must have a timer and thermostats. In addition, her work must be constantly monitored. It is also worth paying attention to the fact that in such rooms where a car is painted, it will not be superfluous to have special sensors that can inform about the start of a fire.
It is worth paying attention to the fact that it is very important to make the correct calculation of where the ventilation ducts will be located. The thing is that their correct location will not negatively affect the quality of the car painting produced.
Types of ventilation
Currently, you have the opportunity to equip several types of ventilation for paint brushes with your own hands, these are:
- single-engine ventilation;
- twin-engine ventilation.
I would like to draw your attention to the fact that with single-engine ventilation in the room, air is supplied under pressure. It is thanks to this that all sorts of small particles settle on the floor. It is there that they are removed from the room with the help of natural circulation. In both types of ventilation systems, special filtration elements are installed. But it is worth noting that control over the clogging of filters must be carried out systematically. When calculating ventilation, pay special attention to the supply ventilation and its operation.
It is believed that both types of ventilation have a large number of convergence. But do not forget that whatever the area of the room in which you are going to paint a car in large quantities, it must be equipped with an excellent ventilation system. To create it, you do not need to contact a specialist. You can do all the work with your own hands. It is worth noting that each type of ventilation, which has been described somewhat earlier, has not only positive, but also negative characteristics. For example, when used at home, twin-engine ventilation is not economically viable.
