Generant loaded filter assembly and method for its use

摘要

The method involves providing a cylindrical filter including an open-ended sidewall formed of a mesh-like filtering material having first and second ends. First and second end caps are of circular, cup-like configuration and include outwardly radially extending barbs positioned around its periphery. The first end cap is positioned within the first end of the filter with its barbs extending into and secured within the sidewall. A gas generant in the form of at least one cylindrical member has an external dia. equal to the internal dia. of the sidewall. One or more gas generant cylindrical members are positioned to fill the sidewall. The second end cap within the second end of the filter has its barbs extending into and secured within the sidewall to form a unitary, generant loaded, filter assembly.
