How Does It Work?The process cleans by flow, and not impact, producing a 'soft' finish. The water acts as a lubricant, avoiding media impregnation and also extending the life of the blast media. The typical process is as follows:
The water/media slurry is contained within the wet blasting cabinet sump. Delivery of the slurry to the manual blast nozzle is via a glandless polyurethane pump and associated hoses located inside the wet blasting machine. Compressed air is added at the blast nozzle to accelerate the slurry and create 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 wet blasting machine.
