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.
Another variety of these equipment are called production tunnels. Like the name suggest, these ones are made in the form of a tunnel. The tunnel has different stations that perform different tasks. For instance, there are stations for coating, cleaning, curing, conveying, and drying among others. The work piece passes through the tunnel as the various processes are performed on it until it emerges from the other side. This makes work to move faster in a production plant.
Normally, the four sides of the cabin applied in this process together with the floor and ceiling are enclosed. The booth comes with two entry doors. One door is for the painter and the other door is meant for the work piece that needs to b worked on. The same door the work piece was taken in is where the it is taken out when the process is finished. Cabins are available in different models. Others have three walls and a ceiling but lack doors.
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.
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.
