Abstract
Abstract An individual portable dust collector includes a ring of filter foam arranged to retain dust of a size in the range 5 microns to 0.5 micron. This ring is accommodated in a rotatable cup and has an exposed lateral surface located in a transverse plane. A cover surrounds the cup and has an air inlet orifice which is also located in said transverse plane. Outlet holes are provided in two diametrically opposed locations in said cover and are spaced from the transverse plane. A cowl caps the inlet orifice and contains a prefiltration block arranged to retain particles of a size greater than 5 microns.
