A gas generator containing perforate internal chambers, each chamber in vapor communication with at least one other chamber in the gas generator, is provided. When granulated compositions are utilized in one or more of the chambers, permeable materials such as cheesecloth, neoprene, Tyvek™, metal or non-metallic screen, and other suitable fluid permeable materials, may be provided to physically seal the perforations of the various chambers, thereby separating the granulated composition(s) contained therein. In this way, off-gas products formed naturally over time may be effectively managed to ensure expected performance criteria of the associated inflator.

1. A gas generator comprising: a housing;a perforate primary gas generant combustion chamber containing a first perforation;a primary gas generant contained within said primary gas generant chamber;a perforate booster chamber operatively associated with said primary gas generant chamber, said perforate booster chamber containing a second perforation;an auto-ignition booster composition contained within said booster chamber, said auto-ignition booster composition containing a primary fuel, a basic constituent, a metallic oxidizer, and a catalyst;an igniter for igniting said composition within said booster chamber, for combusting said primary gas generant;a perforate auto-ignition chamber in thermal communication with said housing, said auto-ignition chamber containing a third perforation;an adsorbent in vapor communication with said primary gas generant chamber prior to actuation of said gas generator;at least one permeable material covering the second and third perforations; andan auto-ignition composition contained within said auto-ignition chamber,wherein said primary gas generant chamber, said booster chamber, and said auto-ignition chamber are in vapor communication with each other prior to activation of said gas generator, and, said perforate auto-ignition chamber is separate from said perforate booster chamber. 2. The gas generator of claim 1 wherein said adsorbent comprises zeolite in vapor communication with the primary gas generant chamber. 3. The gas generator of claim 1 further comprising at least one material selected from cheesecloth, Tyvek, neoprene, metallic screen, and/or non-metallic screen covering the second and third perforations. 4. A gas generator comprising: a housing;a perforate primary gas generant combustion chamber containing a first perforation;a primary gas generant contained within said primary gas generant chamber,a perforate auto-ignition/booster chamber operatively associated with said primary gas generant chamber, said perforate auto-ignition/booster chamber containing a second perforation;an auto-ignition/booster composition contained within said booster chamber, said auto-ignition booster composition containing—aprimary fuel selected from tetrazoles, benzene-based fuels, nitroisophthalic acid, and mixtures thereof; an aromatic or non-aromatic basic constituent selected from amino compounds; salts of amino compounds alkali metal salts of tetrazoles, a potassium salt of an aromatic or benzene-based salt and mixtures thereof; an oxidizer selected from alkali metal nitrate oxidizers; and a catalytic non-oxidizing molybdenum containing constituent selected from molybdenum, molybdenum trioxide, and mixtures thereof;an adsorbent in vapor communication with the primary gas generant combustion chamber prior to actuation of said gas generator;an igniter for igniting said composition within said auto-ignition/booster chamber, for combusting said primary gas generant;wherein said primary gas generant chamber and said auto-ignition/booster chamber are in vapor communication with each other prior to activation of said gas generator. 5. The gas generator of claim 4 further comprising at least one permeable material covering the second perforation. 6. The gas generator of claim 4 further comprising at least one material selected from cheesecloth, Tyvek, neoprene, metallic screen, and/or non-metallic screen covering the perforations of each chamber. 7. The gas generator of claim 4 wherein said adsorbent comprises zeolite in vapor communication with the primary gas generant combustion chamber. 8. A gas generator comprising: a housing;a perforate primary gas generant combustion chamber,a primary gas generant contained within said primary gas generant chamber;a perforate second chamber operatively associated with said primary gas generant chamber, said perforate second chamber containing perforations;a second composition contained within said second chamber;an igniter for igniting said second composition, for combusting said primary gas generant;an adsorbent consisting of zeolite in vapor communication with the primary gas generant combustion chamber prior to actuation of said gas generator; anda permeable material covering said perforations of said perforate second chamber,wherein said primary gas generant chamber and said second chamber are in vapor communication with each other prior to activation of said gas generator. 9. The gas generator of claim 8 further comprising at least one material selected from cheesecloth, Tyvek, neoprene, metallic screen, and/or non-metallic screen covering the perforations of said perforate second chamber.
