Claim 9:
10. A filtration apparatus comprising:
a cylindrical casing having a longitudinal casing centerline, a cylindrical wall having an inside diameter, and first and second end caps, the cylindrical wall and first and second end caps defining a casing interior space, the casing having a first flow port formed through the first cap along the casing centerline and a second flow port formed through one of the first and second end caps;
a prismatic support body disposed within the cylindrical casing along the longitudinal casing centerline, the support body having top and bottom base walls and a plurality of side walls connecting the top and bottom base walls, the top, bottom and side walls defining a support body interior space, the base wall having an outlet flow passage formed there-through, at least one of the side walls having an inlet flow passage formed-there-through and a filtration element receiving channel surrounding the inlet flow passage, and the support body being secured to the first end cap so that the outlet flow passage is in registration and fluid communication with the first flow passage;
a porous filtration structure disposed within the filtration element receiving channel of each of the at least one of the side walls so as to cover the inlet flow passage, the filtration structure being configured for removing particulate matter from a gas flow passing there-through; and
a clamping member attached to each of the at least one side wall, each clamping member having a framing portion and a flange portion, the framing portion extending along a full length and a full width of said at least one side wall and having a flow window formed there-through in registration with the inlet flow passage, and the flange portion extending from the framing portion and being sized and configured for reception into the receiving channel to engage and retain the filtration element within the receiving channel.
