Abstract
A gas conducting system, particularly a compressed air system for a motor vehicle, which includes a filter containing a desiccant for removing moisture from a gas passed therethrough. The housing structure of the filter is provided with a seal with a weakened area 18, which specifically causes any overpressure to be reduced through failure of the weakened area if the pressure inside exceeds a permissible maximum. This process can be repeated multiple times until the seal with the weakened area 18 must be replaced due to aging. The weakened area can be used as a substitute for a pressure relief valve or as supplemental protection in case the pressure control valve fails, e.g., due to ice. This can prevent, for instance, bursting of the filter housing which could present a safety risk.
