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.
