<p>A dust separator, comprising a fan (27) with a drive motor (28), a cyclone separator (10, 11) which is connected to the suction side of the fan and is arranged as a coarse separator and provided with an inlet (11) for gaseous fluid mixed with dust, a filter (29-32) which projects freely coaxially into the cyclone apparatus (10, 11) and is arranged as a fine separator between the interior of the cyclone apparatus and the suction side of the fan, and an outlet (37) for cleaned gaseous fluid at the pressure side of the fan. The filter (29-32) and the suction fan (27) with he drive motor (28) are arranged as a separate unit resiliently connected to the cyclone apparatus (10, 11). The filter (29-32) consists of a pleated outer cover (30) of filter material which is disposed round a perforated tubular core (29) and which is clamped between its ends and the pleats of which extend axially along the core (29) and are fixed to this at their inner folding edges, while the outer folding edges are free. </p> |
