Small spray booths are used in manufacturing or hobby painting to draw fresh air in and expel paint fumes. They use filters, fans, and ventilation. There are three basic designs: three-sided open, four enclosed sides with rubber gloves, and miniature versions of car spray booths.
There are several types of small spray booths built on the same basic principle as the larger versions. Often used in manufacturing or hobby painting, the small spray booth’s primary purpose is to draw fresh air into the booth and expel paint fumes while drawing excessive spray away from the object being painted. Filters, fans and ventilation are the key components used in the design and construction of small spray booths, whatever the intended purpose.
One of the most basic designs in small spray booths is the three-sided open spray booth. This type of spray booth is easy to use in the production sector and allows easy adjustment of the object to be painted. These small spray booths draw in fresh air through the open front panel by installing an exhaust fan at the rear of the booth. The fan draws fumes and excess mist away from the painter and into an exhaust system that carries the toxins to another filter and expels the filtered air into the atmosphere. This type of small cab is the least expensive and offers the least protection from foreign objects being sucked into the cab and landing in wet paint.
Another type of spray booth uses four enclosed sides, however, one side is accessible via rubber gloves designed into the side panel. These small paint booths resemble sandblast boxes, where the user views the object being painted through a viewing window in the front of the booth. Rubber gloves attached to a spray booth panel allow the user to both manipulate the object to be painted and operate the paint gun itself contained within the spray booth. A fan draws air through a vent at the rear of the cab, sending the fumes through a filter and into a ventilation system. The primary advantage of this spray booth over the open booth design is that it eliminates the possibility of debris being drawn into the booth through an open panel.
Some small spray booths are not designed to be used on a table or bench and are actually miniature versions of the booths used to paint cars. This type of smaller spray booth is commonly used for custom painting on smaller components, such as helmets, motorcycle fuel tanks, and fenders. It is also used on bicycles and other smaller items. Often no bigger than a walk-in closet, the small spray booths are equipped with heating components, as well as improved lighting and excellent ventilation to avoid overspray problems on painted parts.
