Innovative spray booth technology for the 'green' paint shop

EcoDryScrubber system of Dürr Systems will be used by Volkswagen's new production facility in Chattanooga, Tenn. The system utilizes a regenerative, dry-filtration process to separate wet paint overspray from spray booth process air. It uses a regenerative, dry-filtration process that yields near HEPA 12 level filtration, allowing for direct-air recirculation of spray booth process air without the need for additional air conditioning equipment. The system operates by directing paint-laden process air into scrubber chambers located directly below and on either side of the painting chamber, with each scrubbing chamber containing an array of porous plastic filter elements. The reduced operating cost and environmental footprint benefits of the EcoDryScrubber are leading to an increased acceptance of the technology by large volume paint finishers.
