Anyone looking for a high-quality finish for their painting job has certainly heard of paint booths. They are ideal for ensuring air quality and purity while applying paint. But did you know that there is more than one type of paint booth, each with special characteristics and developed for different types of work? Let's learn a little more about paint booths, their main models, and which ones are best suited for achieving the best finish for your job.
Paint booths are structures created with the main function of filtering the air from the outside environment, so that during the painting process it is as pure as possible, avoiding dirt that could compromise the quality of the work. Another function of the booth is to filter excess paint overspray, removing excess paint mist from the air that could compromise the work.
However, not all cabins have the same filtration methods, and therefore each one is suitable for different types of work. Let's look at the main models:
Wet paint booth
One of the leading models when considering the quality of air filtration and, consequently, the finish of the service offered, the wet paint booth's main differentiating factor is the aspiration, filtration, and retention of excess paint mist through water curtains. These two filtration barriers are responsible for retaining between 70 and 80 liters of the mist formed by the paint overspray.
Behind the water barrier there is another filtration layer. Through this second layer, now dry, the remaining 20 to 30 liters of overspray are retained. This procedure serves to prevent a series of unwanted contaminations on the parts.
To the wet paint booths, In turn, they are differentiated into models with or without an extended tank. Models without a tank are suitable for parts that do not require a high standard of finish. Models with an extended tank allow parts to be painted over this extension, without the paint coming into contact with the ground, and are suitable for painting jobs that require a high standard of finish.
Wet paint booths are an excellent choice for furniture manufacturers concerned with the quality of the final product. Due to their varying sizes, they can handle the painting of a variety of parts, from small to medium formats, such as chairs, plastic parts, automotive items, furniture, and more.
Dry paint booth
Just like wet paint booths, the dry paint booths They also cause the air to go through an extensive aspiration and filtration process. The basic difference lies in the fact that in dry paint booths, the first filtration process takes place using a letter-type filter, which is responsible for retaining 70% of impurities.
Just like in wet process cabins, the process goes through a second filter, responsible for filtering the other 30%. This process means that the cabin's productivity, although still high, is lower than that of wet cabins, resulting in a cabin operating time that does not exceed four hours of use.
This type of booth comes in a variety of models and sizes, and can be used for painting various items, especially in automotive painting and its variations.
Powder coating booth
To the powder coating booths Their main function is to vacuum and filter the excess dust generated in the metal painting process. Specifically designed for powder-based paints, it has a cartridge filter system that allows the overspray dust to be reused instead of being discarded.
In addition to reusing virtually all the material that would otherwise be discarded, the powder coating booth prevents residues from being exposed and harming – as well as the ecosystem – the factory environment, which could cause damage to the worker's health.
Powder coating booths are widely used in sectors that work with metal painting. They are ideal for those seeking to achieve more durable paint results with less process control. They can also be equipped with an automatic filter cleaning system, which is achieved through solenoid valves that generate air pulses into the cartridge filters of the paint booth, considerably increasing the lifespan of the filters and consequently reducing maintenance costs.
