Air Blast Cabinet

https://www.etsaindustry.com/products/air-blast-cabinet.html

The working principle of a dry sandblasting cabinet is to use compressed air to accelerate abrasive particles to high speed, and then spray them onto the surface of the object to be treated through a nozzle. During the process of impacting the surface of an object, abrasive particles can effectively remove surface dirt and coatings, while also improving the surface roughness and increasing its adhesion.
