A device for separating particles from a gas by screening, comprising a bag-shaped, elongate filter member (5), such as a filter bag or a filter cell, at least three longitudinal, substantially parallel rods (10) positioned at a distance from each other adpated to the inner dimensions of the filter member in the expanded state thereof, and transverse stiffening means (7) for fixing the distance between the rods. The rods (10) further cooperate with means (6) arranged on the surface of the filter member (5), for fixingly receiving the rods. |
