How vapour blasting works

The key to vapour blasting is that the finish is produced through flow of water borne abrasive, giving a finer finish due to the flushing action of the water.

No media is impregnated into the component, nor is there any dust created by the break-up of media, unlike dry blasting where the finish is produced by sheer force of media impact

A specially designed glandless polyurethane pump agitates water and media into a slurry, and pumps it to the blast gun. At the same time this slurry is pumped at approximately 2 bar to the nozzle, and air is introduced at the blast gun to accelerate the slurry and its cleaning effect on impact, albeit cushioned.
