Spray or coating booths refer to enclosures used to perform spray-coating processes. Some of spray-coating processes that can be performed inside the booth include thermal spraying, powder coating, and painting among other deposit methods. The product is made up of various parts, including tunnels, hoods, and cabinets among others. Each part has a specific role in the whole unit.
Presently, these systems exist in different models. Spray booths and rooms are among the most common types. Both are applicable in processing huge work pieces. The painting or coating machine, the operator, and work piece can be accommodated inside the rooms. Booths have recovery systems, internal ventilation, and lighting. The operator may operate the gun employed in offhand mode. Guns are reciprocator-mounted in other situations.
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 variety of these machines. They are created in the shape of a tunnel just as suggested by the name. There are different stations in the tunnel where various tasks are done. Stations for conveying, curing, drying, cleaning, coating and others are examples. Through the tunnel, work pieces are passed down. As the work piece passes down through the tunnel, it is worked on until it emerges from the other end. With that, the work is done at a faster rate in a production plant.
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 ways ventilation is achieved into these units. Mostly, air is allowed in via the roof from where it passes through a filtration system. After this the air is forced vertically into the unit and can be let out using the 3 major methods available.
The three methods are downdraft exhaust pit design, downdraft exhaust wide-wall, and downdraft exhaust rear-wall design. Each of the methods of removing air can be used but some are more effective than others. Thus, the choice of exhaust method usually determines the final results achieved in the painting or coating process.
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
