the casing between the dusty and clean sides is effective. To prevent dust leakage at weak points, we increased the contact surface area of the bag against the tube sheet by extending and contouring the tube sheet opening. The surface contact is therefore not limited to the pure thickness (typically 4 mm or 5/32") of the plate, but is
