ABSTRACT:
A dust arrester for a sanding machine includes a hollow workbench and a tubular filter unit which is axially rotatable inside the hollow workbench. A suction unit draws polluted air into the workbench to be filtered by the filter unit. A blowing unit is disposed inside the filter unit and generates a downwardly oriented air stream to blow dust particles collected by the filter unit into a removable dust receiving bin inside the workbench. The dust arrester is simple in construction, has a relatively low cost, and can effectively control air pollution.
