Impact offer a highly efficient and fully certified spray powder and conveyor fume extraction system to eliminate unwanted odours and dangerous explosive overspray from the lacquer that is applied to the internal surface of the beverage can. Over spray from the lacquer spray application is efficiently extracted along with the solvent fumes emitted from the transportation conveyor to the IBO.
Explosion rated ductwork conveys the spray dust and fumes to a fully automatic reverse jet filter assembly. This (ATEX compliant) filter unit provides primary recovery of the dust and includes vertical discharge explosion relief panels and discharge chute allowing filtration to be located in close proximity to the spray process. A second stage filter followed by a third stage absolute filter ensures a cleaning efficiency of above 99.9% is achieved.
The conveying air stream is provided by a high efficiency centrifugal fan equipped with spark minimizing features which is installed on the clean side of the filtration system.
