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.
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.
Processing big work pieces also require huge rooms or booths, hence such units are normally big in size. But, for smaller units are used to process small work pieces. As such, paint spray hoods, open-faced booth, and coating cabinets are used. These systems are designed small meaning that only smaller coating equipment and work pieces can fit in. They cannot accommodate the operator. They are mostly used in small scale businesses for handling small pieces 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.
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.
The units differ a lot in terms of size. The type of job one is getting the unit for should determine the size of machine to choose. The price also differs, with huge units costing more. Fortunately, the investment can be easily recouped once the system is running and offering services to customers.
