One of the most important maintenance and pollution control equipment in the finishing section in furniture factories is the spray booth. A spray booth acts as a pressure-controlled closed environment used in finishing sections to minimize pollution from overspray and reduce VOC emission (Tank 1991). To ensure optimal working conditions (temperature, airflow, and humidity), spray booths are equipped with ventilation, comprising of mechanical fans driven by electric engines, and alternatively with burners to heat the air, to hasten the drying of the coating (Fig. 8.9). As a guideline, airflow speed across the surface of the spray booth should be maintained 0.5 m/s, while the air exchange volume at the spray booth, with an area 7.5m2, should be approximately 3.5m3/s (Talbert 2008). This is to ensure toxic solvents and coating particles are exhausted to the outside environment, after filtration, and necessary treatment to reduce air pollution. Fires and explosions due to dust is also prevented by the spray booths. Water-washed spray booths utilize specialty chemicals to minimize tacking of the coatings, and a down-draft air to effectively capture overspray, while reducing air pollution (Tichy 1997).
