3. General Description
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.
To commence blasting, simply depress the lever on the POWER 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.
