Abstract: Disclosed herein is a vacuum filter segment including a segment frame made up of a sector-shaped frame partially defining a generally sector-shaped central open area and a throat adapted for sealing engagement with a vacuum manifold and for communicating with the central open area. A pair of sector plates are removably secured in a spaced apart mounted position in engagement with the frame and further define the central open area. The sector plates are adapted for supporting a filter medium and include apertures for affording communication between the central open area and the filter medium. The filter segment includes fasteners for removably securing the sector plates without requiring integral bonding or welding of the fasteners to the frame in the mounted position. The frame and sector plates are preferably composed of steel having a urethane coating so as to resist abrasion and corrosion.
