With proper support, you can get the biggest out of your spray booth The paint booth is arguably one of the greatest important tools in the collision revamp paint department. While the spray booth was first changed to keep harmful overspray contained and away from other workers in the shop, it has evolved into a tool that not only protects workers but furthermore cuts down on infection of the environment, keeps work clean, and speeds up application and curing - thus expanding shop production. The booth has developed over the years from just a box to paint in to a self-contained painting environment, one that regulates airflow, lighting and temperature, and controls dirt infection. There are attached mixing rooms and vestibules, and there is even talk of paint booths that control or eliminate VOC emissions. Through an integral investment, a properly maintained and efficiently operated paint booth can produce 10 or more paint jobs per day. Paint booth technology has mutated as paint has mutated, and paint booth manufacturers have reformed equipment to meet modern needs. Some of the first booths used when lacquer was the primary coating were the crossdraft type, conventionally a simple non-insulated box that had filters at both ends and commonly worked by drawing air in from the rear and exhausting it at the front. Booths of this type worked mostly to contain overspray and exhaust it to the outside. Lacquer paint dried mainly through evaporation, and a crossdraft booth helped speed up the curing time, though evaporation time before the paint could be buffed (necessary with lacquer paint) was mainly 18 to 24 hours. These booths were a significant convalescence over spraying vehicles in the shop, and they protected workers outside the spray area from overspray. Crossdraft booths had some all-important problems. They drew in humongous amounts of air through the rear door, which in the wintertime could integrally lower the shop's temperature and tax the building's heating capability. They also drew enormous amounts of air, contaminated with shop debris, across un-cured paint, often depositing dirt as the filters become filled. Filter technology at this time was crude at best, drawing air through paper arresters (filters). The openings in these paper filters were offset causing the air to change direction and depositing paint mist on the paper as it passed by. Greatest paint fumes were exhausted out the paint stack. As incoming air quickly contaminated the rear booth filters, it allowed biggest of the dirt and debris to pass through into the booth. All vehicles painted with lacquer were polished at the time to create the desired shine so small dirt particles were eliminated during the polishing. The next type of booth that was mutated was the semi-downdraft booth. In these booths, air was drawn in from outside, heated as needed and entered the booth through the top at the rear, drawing it down over the vehicle and exhausting it out the front at or near the floor. These booths were an amendment over the simple crossdraft booth because of their ability to heat air while not contaminating the vehicle with shop dirt. Filter technology additionally was changing. Newer filters passed air through fiberglass that got progressively finer textured, filtering out much more than paper arresters were ever capable of. Incoming air was cleaned with a pre-filtering and then passed through the ceiling filters, supplying much cleaner air in the paint area. The air still traveled from the top rear, passing over the entire vehicle to be exhausted out the lower front, and if any dirt did get in or if there was a leak in the booth, dirt was still drawn over the vehicle, depositing it on fresh paint as it passed by.
