A retention screen for use in an adsorption canister has outer edges including a seal groove that form a relatively thick portion and a plurality of support pad portions also formed to be relatively thick and relatively thin connecting web portions connecting the outer edge to the support pad portions. The connecting web portions also connect the support pad portions to each other. The retention screen is generally planar. The edge portions and the support pad portions are thicker than the connecting web portions. An adsorption system and a method of manufacture are also disclosed.

1. A retention screen for use in an adsorption canister comprising: an outer edge including a seal groove and formed to be relatively thick and a plurality of support pad portions also formed to be relatively thick, and relatively thin connecting web portions connecting said outer edge to said support pad portions, and the connecting web portions also connecting said support pad portions to each other, with said retention screen being generally planar and with a thickness of said outer edge and said support pad portions being thicker than a thickness of said connecting web portions. 2. The retention screen as set forth in claim 1, wherein the thickness of said outer edge and the thickness of said support pad portions being generally equal. 3. The retention screen as set forth in claim 1, wherein said support pad portions and said connecting web portions define a plurality of spaces to support an adsorption media. 4. The retention screen as set forth in claim 3, wherein said spaces being sized and designed to capture a minimum bead size of the adsorption media to be retained by said retention screen. 5. The retention screen as set forth in claim 3, wherein said spaces are generally triangular. 6. The retention screen as set forth in claim 1, wherein said support pad portions are formed with a plurality of gas flow holes. 7. The retention screen as set forth in claim 6, wherein said support pad portion is formed by a plurality of interconnected web portions. 8. The retention screen as set forth in claim 1, wherein said outer edge portion is formed with vent slots. 9. The retention screen as set forth in claim 1, wherein said support pad portion is formed by a plurality of interconnected web portions. 10. An adsorption system comprising: a canister including a canister housing and opposed covers;an adsorption material space defined between said covers, and retention screens placed between said space, and each of said covers, and an adsorption media received in said space, and between said retention screens;and at least one of said retention screens having an outer edge formed integrally with web portions, said outer edge having a seal groove, and receiving a seal; andwherein said outer edge formed to be relatively thick and a plurality of support pad portions also formed to be relatively thick and relatively thin connecting web portions connecting said outer edge to said support pad portions, and the connecting web portions also connecting said support pad portions to each other, with said retention screen being generally planar and with a thickness of said outer edge and said support pad portions being thicker than a thickness of said connecting web portions. 11. The adsorption system as set forth in claim 10, wherein the thickness of said outer edge portions and the thickness of said support pad portions being generally equal. 12. The adsorption system as set forth in claim 10, wherein a distance between said connecting web portions defining support spaces, and said support spaces being sized and designed to capture a minimum bead size of the adsorption media to be retained by said retention screen. 13. The adsorption system as set forth in claim 10, wherein said support pad portions are formed with a plurality of gas flow holes. 14. The adsorption system as set forth in claim 13, wherein said support pad portion is formed by a plurality of interconnected web portions. 15. The adsorption system as set forth in claim 10, wherein said outer edge portion is formed with vent slots. 16. The adsorption system as set forth in claim 10, wherein said support pad portion is formed by a plurality of interconnected web portions. 17. The adsorption system as set forth in claim 10, wherein support pad portions are in contact with a pedestal on said covers. 18. The adsorption system as set forth in claim 17, wherein there are holes in said support web portion to facilitate flow of gas outwardly of said pedestals. 19. An adsorption system, comprising: a canister including a canister housing and opposed covers;an adsorption material space defined between said covers, and retention screens placed between said space, and each of said covers, and an adsorption media received in said space, and between said retention screens; andat least one of said retention screens having an outer edge formed integrally with web portions, said outer edge having a seal groove, and receiving a seal, and said outer edge having a thickness defined in a direction toward the other of said retention screens from said at least one of said retention screens, and a thickness of said outer edge being thicker than a thickness of said web portions, and said seal groove formed in a face of said outer edge facing the other of said retention screens. 20. The adsorption system as set forth in claim 19, wherein said outer edge formed to be relatively thick and a plurality of support pad portions also formed to be relatively thick and relatively thin connecting web portions connecting said outer edge to said support pad portions, and the connecting web portions also connecting said support pad portions to each other, with said retention screen being generally planar and with a thickness of said outer edge and said support pad portions being thicker than a thickness of said connecting web portions.
