Abstract
A dust remover for power sander includes a dust collecting hood secured on the sander and fluidically communicated with a vacuum system formed in or attached to the sander, having a resilient bellows portion formed on a lower portion of the hood for covering a sanding pad as driven by a motor of the sander and a bottom flange having a plurality of apertures or perforations circumferentially formed in the flange, with the bellows portion resiliently expanding to retain the bottom flange on a working surface; whereby upon vacuum suction in the sander to form at least an air stream as drafted from the outside into the inside of the hood, the dusts, as produced when operating the sander, will be sucked inwardly into the hood as laden in the air stream to be finally collected and disposed for preventing air pollution and for enhancing occupational health.
