Information : High-Volume Low-Pressure Spray Guns and Cleaning Equipment
To mitigate some of the problems associated with maintaining nine paint booths and their related volatile organic compound (VOC) and cleaning emissions, Choo Choo Customs, a customizer of vans and pick-up trucks, replaced its paint spray guns with gravity-fed, high-volume low-pressure guns; added gun wash systems for spray gun cleaning; and installed a computerized paint mixing system.
Besides the VOC emissions, paint costs were constantly rising; any modifications to the process could trigger further regulatory limits; and approximately 40% of the paint used was being wasted in overspray. The high-volume low- pressure spray guns reduced overspray from 40% to 20%, creating almost 30% in paint savings per year and considerably reduced VOC emissions. The gun wash system which was installed further reduced the VOC emissions and reduced costs. The computerized paint mixing system, a commercial system manufactured by PPG, allowed the company to mix as little as one ounce of custom paint at a time. This controlled mixing and the gravity-fed high- volume low-pressure spray guns further reduced paint usage.
