Abstract
A filter cartridge includes a filter media defining an interior space, and having a first end and a second end, a first end plate connected to the first end, and a second end plate connected to the second end. A pin is connected to the second end plate and extends downwardly into the interior space. The pin defines a flow passage therethrough that communicates the interior space with an outside of the filter cartridge.

A filter cartridge, comprising:
- a filter media defining an interior space, and having a first end and a second end;
- a first end plate connected to the first end;
- a second end plate connected to the second end,
- a center tube connected to the second end plate, a pin being formed as a single piece with the center tube and extending away from second end plate into the interior space, the pin defining a flow passage therethrough, the center tube defining an inner cavity between the second end plate and the pin, the inner cavity structured to receive air, wherein engagement of the pin with an air flow passage places the air in the inner cavity in communication with an outside of the filter cartridge through the flow passage of the pin.
