Reducing spray booth overspray, volatile organic compounds (VOC) emissions and solid waste can be achieved in every installation--from the simplest one-gun booth to the high-production multigun booth. The changes may be as basic as getting the present system under control or changing to another process. Conventional, airless and electrostatic application methods have been available to the finishing market for over 25 years. Each method has advantages and disadvantages. As VOC restrictions began to close in on the coatings industry, the need to improve spray equipment capability increased. The principal objective was to increase transfer efficiency to decrease VOCs.
