Portable suction blast tool SFG

The Contracor SFG Gun is a suction blast tool ideally suited to small jobs or locations with limited air supplies. Thanks to its light weight and compact dimensions, the Contracor SFG Gun can be used in places where erecting a conventional pressure blast machine would be awkward or inconvenient.
The SFG Gun can be used with all common blast media, to clean or etch metal, glass, stone or other hardwearing surfaces.
To operate the SFG Gun, just connect it to a compressed air source, and plunge the suction lance into the blast media, or alternatively, fill blast media into the portable container.

To commence blasting, simply depress the lever on the SFG Gun. The tool operates according to Bernoulli's principle, where a low-pressure area is created by the compressed air rushing past the abrasive-injection point, where the abrasive hose is connected to the gun. This low-pressure area draws abrasive into the airstream, where mixing takes place. The air-abrasive mix is then exhausted out of the gun and strikes the blasting surface.
