Coating booths and spray booths are enclosures used to contain spray-coating processes such as painting, powder coating, thermal spraying, and other deposition methods. This product area includes hoods, cabinets, tunnels and similar enclosures. Many different types of coating booths and spray booths are available. Spray rooms or spray booths are used to process larger workpieces. A spray room contains the painting or coating equipment, the workpiece, and the operator. A spray booth usually contains internal lighting, ventilation and recovery systems. The operator may operate the spray gun in offhand mode, or the gun may be reciprocator-mounted. Often, the workpiece rests upon open-grid flooring that allows for the recycling of excess paint or powder. Paint spray hoods and benchtop open-faced booths or coating cabinets are smaller vessels that contain the workpiece and/or process. Continuous spray booths or production tunnels consist of long walk-in enclosures which contain continuous processing lines and systems for cleaning, coating, drying or curing, and conveying or material handling.
Coating booths and spray booths are used with powder coating systems. Powder coating equipment applies powder to a substrate and fuses it into a continuous film through the application of heat or radiant energy. In a fluidized-bed powder coating systems, hot parts are introduced and suspended powder coating particles stick or fuse onto the part's surface. Air is blown through a porous bed or screen to suspend the powder coating particles. In electrostatic powder coating systems, the particles are given an electric charge that causes them to be attracted to an oppositely charged part. For example, paint droplets or coating particles are charged and then sprayed toward a part with an opposite and attractive electric charge. The spray process may be airless or air assisted.
Coating booths and spray booths are used with centrifugal or dip-spin systems in which the entire part is dipped into a tank filled with paint or coating media. The excess coating or paint is then removed by spinning the part. Bulk processing of small parts is accomplished by dipping a mesh basket of parts, followed by rapid rotation of the basket to remove excess paint. Parts from the dip-spin coater are dumped onto a conveyor belt for curing.
Coating booths and spray booths differ in terms of dimensions, construction materials, and features. Dimensions include internal width, internal height, and internal length. Construction materials include steel, aluminum, plastic, stainless steel and other materials. Some coating booths and spray booths contain color change, air filtration, and composites sprayup features. Others contain an integral agitator, integral regulator, or catalyst injector.

Powder Coating Equipment
Powder coating equipment is used to spray resin powder onto the surface of a pre-heated component, where the powder fuses and cures producing a protective coating.
Spray Guns and Applicators
Spray guns and applicators form a coating by directing atomized paints, adhesives, liquids, or powders toward a surface. These devices affect droplet sizes and spray patterns which influence the efficiency of the spray.
Spray Painting Equipment (Paint Sprayers)
Paint spraying equipment and paint sprayers are used to atomize and propel a concentrated mist of a finish coating onto a surface. This includes the equipment used to directly apply the spray coating, as well as a variety of supporting equipment to optimize the painting process.
Sprayers and Spray Coating Equipment
Sprayers and spray coating equipment refers to any component used in a variety of industrial spraying processes, including application tools, handling equipment, and supplemental machines. They are used in the process of atomizing coatings, paints, lubricants, solvents, deicing liquids, chemicals, and powders so they can be spray-applied to a surface.
