An air bag inflator (10) includes an ignitable gas generating material (50), an initiator (36) for igniting the gas generating material (50), and a tubular wall (100) defining a combustion chamber (54) containing the gas generating material (50). A plurality of gas flow openings (150) extend radially outward from the combustion chamber (54) through the tubular wall (100). A filter (102) extends circumferentially and axially over the tubular wall (100). The tubular wall (100) includes a structure (160) defining a space which provides plenum (170) extending radially outward from the gas flow openings (150) to the filter (102).
