Abstract
Abstract A filter element (2) comprises a narrow strip (6) of a pliable porous dielectric material having electrodes (7) embedded or sandwiched therein along the length thereof. A gasflowto be treated is constrained by a casing 1 or duct 21 to pass through the porous dielectric (6) while a voltage (8,22) is applied to the electrodes. The strip (6) of the filter element (2) is disorderly packed into the casing (1) or duct (21). The dust collector thereby has the advantages of both a filter and an electrostatic dust collector as regards collecting a wide range of particle size and without requiring a very high voltage.
