Mechanical interlock system for a filter

A mechanical interlock system, comprising:

• a filter cartridge comprising:
• a filter body having a first end, a second end, and a longitudinal axis;
• a fluid inlet and outlet at the first end of the filter body;
• and
• an integrated locking head on the first end of the filter body, wherein the integrated locking head comprises:
• a key extending radially outward from the integrated locking head;
• and
• at least one displaceable latch feature extending longitudinally from the integrated locking head;
• and
• a manifold for receiving the filter cartridge, the manifold comprising:
• at least one receptacle on an inner surface of the manifold, the at least one receptacle structured for receiving the at least one displaceable latch feature, preventing rotation of the filter cartridge in a first direction, and permitting rotation of the filter cartridge in a second direction, wherein the at least one receptacle is structured to:
• prevent, after the at least one displaceable latch feature has been received by the at least one receptacle, movement of the filter cartridge in a direction along the longitudinal axis that is opposite an insertion direction;
• prevent rotation of the filter cartridge in the first direction;
• and
• permit rotation of the filter cartridge in the second direction;
• an extraction guide for receiving the key, wherein the extraction guide comprises:
• a primary keyway;
• and
• a secondary keyway, wherein the secondary keyway has an entry end and an exit end, and wherein the exit end of the secondary keyway connects to the primary keyway.
