Also due to this particular arrangement of the air flow generator set, in an independent body, the pistol becomes significantly lighter, as it only houses the electrical resistance and the temperature and speed commands, overcoming the discomfort caused by excessive weight perceived after many hours of uninterrupted operation, as is usually the case with hair dryers covered by the current state of the art.
