The test port member may be positioned adjacent the outer periphery of the outer peripheral frame and may be attached to a truncated portion of the filter media. One or more scrim layers may be disposed across one or more sides of the test port member and/or the truncated portion of the filter media. A plug may be inserted into a through port of the test port member.
1 . A filter apparatus comprising:
a filter media having an outer periphery, wherein a front face and an a rear face is defined by said outer periphery, and wherein said outer periphery of said filter media includes a truncated portion;
a test port member having a through port extending between a front face and an opposing rear face;
an outer peripheral frame receiving said filter media and said test port member thereby positioning said rear face of each said filter media and said test port member adjacent to each other and correspondingly positioning said front face of each said filter media and said test port member adjacent to each other; and
wherein the test port member is received between said outer peripheral frame and said outer periphery truncated portion of said filter media.
2 . The filter apparatus of claim 1 further comprising a scrim disposed across said test port member and said filter media.
3 . The filter apparatus of claim 2 wherein said scrim includes an opening coaxial with said through port of said test port member.
4 . The filter apparatus of claim 3 further comprising a plug received in said opening of said scrim and said through port of said test port member.
5 . The filter apparatus of claim 1 wherein said rear face and said front face of said test port member is triangular in shape.
6 . The filter apparatus of claim 1 wherein said outer peripheral frame defines an opening, wherein said filter media and said test port member is disposed across said opening.
7 . The filter apparatus of claim 1 wherein said outer peripheral frame receives a single said filter media.
8 . A filter apparatus comprising:
a filter media having an outer periphery, wherein a front face and a rear face is defined by said outer periphery;
a test port member having a through port extending between a front face and an opposing rear face, wherein said front face and said rear face of said test port member is defined by an outer periphery;
an outer peripheral frame receiving said filter media and said test port member; and
wherein said test port member is attached to said outer peripheral frame and said outer periphery of said filter media, wherein a portion of said outer periphery of said test port member engages said outer periphery of said filter media and an entire remaining portion of said outer periphery of said test port member is adjacent to said outer peripheral frame.
9 . The filter apparatus of claim 8 further comprising a scrim layer disposed across at least one of said front face of each said test port member and said filter media and said rear face of each said test port member and said filter media.
10 . The filter apparatus of claim 9 wherein said scrim layer is disposed across said rear face of said test port member and said rear face of said filter media.
11 . The filter apparatus of claim 8 wherein said outer peripheral frame includes one or more frame members defining an opening therein, wherein said entire remaining portion of said outer periphery of said test port member engages two nonparallel sides of said one or more frame members.
12 . The filter apparatus of claim 8 wherein said filter media includes a truncated corner, wherein said truncated corner engages said portion of said outer periphery of said test port member.
13 . The filter apparatus of claim 8 further comprising a plug received by said through port adjacent said rear face of said test port member.
14 . The filter apparatus of claim 8 wherein said outer peripheral frame includes one or more frame members defining an opening therein, wherein two adjacent sides of said one or more frame members create an inside corner of said outer peripheral frame, wherein said inside corner engages said entire remaining portion of said test port member.
15 . A method of manufacturing a filter apparatus comprising the steps of:
providing a U-shaped portion of an outer peripheral frame at least partially defining an through opening of the filter apparatus, said U-shaped portion having a center frame member and a lateral frame member extending from each end of said center frame member,
providing a test port member having a through port;
attaching said test port member to one of said lateral frame members and said center frame member within said U-shaped portion;
providing a filter media;
removing a portion of said filter media thereby creating a truncated portion of said filter media;
inserting said truncated portion of said filter media into said U-shaped portion, wherein said test port member fills the void left of said portion of said filter media removed; and
assembling a remaining portion of said outer peripheral frame to said U-shaped portion.
16 . The method of claim 15 further comprising the step of inserting a scrim on at least one of a rear face of each of said test port member and said truncated portion of said filter media and a front face of each of said test port member and said truncated portion of said filter media.
17 . The method of claim 16 wherein said scrim is on said rear face of each of said rear face of each of said test port member and said truncated portion of said filter media.
18 . The method of claim 17 wherein said scrim is on said front face of each of said rear face of each of said test port member and said truncated portion of said filter media.
19 . The method of claim 15 further comprising a step of inserting a plug into said through port of said test port member.
20 . The method of claim 15 wherein said test port member is adhesively attached to each of said center frame member, said lateral frame member, and said truncated portion of said filter media.
21 . A filter having a testing port, comprising:
a pleated v-shaped filter media having a front face and a rear face, the pleats extending to a predefined height;
a test port member having a through port extending between a front face and an opposing rear face of the test port;
a plug received within the through port of the test port member, the plug removably affixed within the through port;
a peripheral frame receiving the filter media and the test port member and maintains them in adjacent relationships;
wherein the test port member is retained by the peripheral frame and is positioned between the peripheral frame and a truncated portion of the pleated v-shaped filter media, wherein a first portion of the test port member engages an outer periphery of the filter media and a second portion of the test port member is adjacent to the peripheral frame;
the pleated v-shaped filter media having the truncated portion, the test port adjacent the truncated portion, both the v-shaped filter media and the test port retained within the peripheral frame and forming a rectangular filter.
