ABSTRACT:
A portable individular dust collector has a cover which surrounds a rotatable cup. A hood is supported on the cover and houses a prefiltration unit carrying an auxiliary cup containing a filtering foam. The prefiltration unit and said hood define an external peripheral space which is in communication with an annular volume provided beneath said prefiltration unit around a central air inlet in the direction of the rotatable cup to retain the coarser particles of dust.
