The water/media slurry is contained within the cabinet sump. Delivery of the slurry to the manual blast nozzle is via a glandless polyurethane pump and associated hoses located inside the machine. Compressed air is added at the blast nozzle to accelerate the slurry and provide the cleaning effect. After contact with the component the slurry then drains back into the sump creating a re-circulating system. Fine broken down media and other contaminants are fed via an overflow to a sedimentation filter located at the rear of the cabinet. The process cleans by flow not by impact, producing a 'soft' finish with the water acting as a lubricant which not only avoids media impregnation but also extends the life of the blast media.
