Enclosures that are applied in performing spray-coating processes are called coating or spraying booths. Powder coating, thermal spraying, and painting are among spray-coating processes that can be done inside the booth. Hoods, tunnels, cabinets and other components form parts of the booth. In the entire unit, every part plays a specific function.
Today, there is a wide variety of these units in existence. The commonest ones include spray rooms, and spray booths. These two versions are used in processing big pieces of work. For example, a spray room is capable of accommodating the operator, the coating or painting machine, and the work piece. A booth on the other hand has recovery systems, lighting, and internal ventilation. The spray gun used can be controlled by the operator using offhand mode. The guns can also be reciprocator-mounted.
Spray booth and room are usually large in size and are meant for processing large work pieces. However, for small work pieces, there are smaller systems that are used. These ones include open-faced booth, coating cabinet, and paint spray hoods. These ones can accommodate only smaller work pieces and the coating equipment. The operator cannot fit inside them. These ones find use in small businesses where they are used to handle a smaller amount of work.
Production tunnels are another version of these units. As suggested by their name they are designed in form of tunnels. Inside the tunnels are various stations for handling specific tasks. The included stations are cleaning, drying, conveying, curing, and coating areas among others. The work piece is passed in the tunnel from station to station as different processes are applied on it until it emerges at the other end. This enables production plants handle work faster.
The cabin used in this process is usually closed on all four sides, including the ceiling and the floor. The booth has two entry doors for the painter and another one for the product that needs to be coated or painted. Once the process is complete, the work piece is removed through the same door it was brought in. There are different variations of these units, with others lacking doors but instead having three walls and a ceiling.
There are several means by which the flow of air is attained in these units. In many situations, the ceiling forms the entryway for fresh air into the system. From there, the air is filtered by an air filtration system. The air then enters into the cabin and it can get out through any of the three major ways present.
Downdraft exhaust-rear wall design, downdraft exhaust pit design, and downdraft exhaust wide-wall the three commonly used methods. Any of these methods of air removal may be applied, although the efficiency of some is better than that of the others. As such, the quality of results attained in the coating or painting process is determined by the choice of exhaust method.
There are great variations in sizes among booths. The size chosen needs to base on the type of work the system is needed to perform. They also come with different prices. The large designs may go at several hundreds of thousands of dollars. The investment can be recovered with ease once installation of the system is done and clients pay for service
