Sandblasting for rooms almost dust free

Another design of a sandblasting apparatus based on a blowing gun is different in that it provides for the collection of sand in a special bag. Due to its peculiarity, it is possible to use this sandblast to trap dust indoors.

A housing made of polypropylene tees allows hermetically connecting the air, sand and bag for collecting activity products. A thin iron tube passes into this casing, into which sand enters and, under the influence of an air stream, it cleans the surface under the nozzle.

A sealant is glued to the front of the sandblasting unit and when cleaning the sand only cleans the surface inside the nozzle.
