The annular groove is located at a junction between an extended bottom portion of the filter holder and the metal bottom clamp. In another aspect of the filter assembly, an inner surface of the filter holder designed to receive a fail-safe regenerator having at least one locking groove formed thereon is disclosed. The locking groove has at least two portions formed in communication with the interior of the filter holder. The locking groove can include a first axial groove portion and a second circumferential groove portion in communication with each other. Each portion of the locking groove is structured to receive therein a tooth formed integrally with or connected to a fail-safe regenerator device.
