The aspirator creates a vacuum that draws wood dust up through the holes of the sanding pad. An innovative dust control system has been developed that uses additional exhaust and a slottedanding pad. [3] LEV for orbital sanders [3] Dust control plenum for orbital sander [3] A new dust control plenum has been designed for orbital sanders.
Tap water is not sterile and may contain waterborne germs, such as bacteria, fungi and amebas, which form a biofilm barrier to water treatment chemicals — mainly chlorine and chloramine ...
