Abstract
A method for filtering a gas includes delivering a gas into a compartment of a gas filter assembly; applying a partial vacuum to the gas filter assembly so that the partial vacuum assists in drawing the gas through a porous filter body of the gas filter assembly that is at least partially disposed within the compartment of the gas filter assembly; and regulating the application of the partial vacuum based on a pressure reading of the gas upstream or downstream of the gas filter assembly.
