The Contracor Power 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 Power Gun can be used in places where erecting a conventional pressure blast machine would be awkward or inconvenient. The Power Gun can be used with all common blast media, to clean or etch metal, glass, stone or other hardwearing surfaces. To operate the Power Gun, just connect it to a compressed air source, and submerge the suction lance to which the abrasive hose is connected partially into a container of blast media.
