Filter cartridge
A filter cartridge includes a casing that is mountable to a filter manifold. A leak collector is mounted to the casing at a bottom portion of the casing. The leak collector has a trough that extends about a sidewall of the casing. The trough of the leak collector is sized and positioned for receiving liquid flowing down the sidewall of the casing at the bottom portion of the casing.
1. A filter cartridge, comprising:
a casing having an exterior surface and an interior volume, the casing mountable to a filter manifold, the casing also having a sidewall;
a filter medium disposed within the interior volume of the casing;
a radio-frequency identification (RFID) tag mounted to the casing at the exterior surface of the casing;
a wicking material; and
a leak collector mounted to the casing at a bottom portion of the casing, the leak collector having a trough that extends about the sidewall of the casing, the trough of the leak collector sized and positioned for receiving liquid flowing down the sidewall of the casing at the bottom portion of the casing,
wherein the RFID tag is positioned above the trough of the leak collector, and
wherein the wicking material extends between the trough of the leak collector and the RFID tag.
2. The filter cartridge of claim 1 , wherein the exterior surface of the casing defines a diameter at the bottom portion of the casing, the trough of the leak collector also defining a diameter, the diameter of the trough being larger than the diameter of the exterior surface of the casing at the bottom portion of the casing.
3. The filter cartridge of claim 1 , wherein the trough of the leak collector slopes towards the wicking material.
4. The filter cartridge of claim 3 , wherein a highest point of the trough along a vertical direction is positioned opposite the wicking material about the casing.
5. The filter cartridge of claim 1 , wherein the RFID tag is recessed within the casing at the exterior surface of the casing.
6. The filter cartridge of claim 1 , wherein the casing and the leak collector are integrally formed with each other from a common material.
7. The filter cartridge of claim 1 , wherein the leak collector is mounted to the casing via adhesive, spin welding or ultrasonic welding.
8. The filter cartridge of claim 1 , wherein the leak collector has an installation assist fin that projects away from the bottom portion of the casing.
9. A filter assembly, comprising:
a manifold;
a filter cartridge removably mounted to the manifold, the filter cartridge comprising
a casing having an exterior surface and an interior volume, the casing also having a sidewall;
a filter medium disposed within the interior volume of the casing;
a radio-frequency identification (RFID) tag mounted to the casing at the exterior surface of the casing;
a wicking material; and
a leak collector mounted to the casing at a bottom portion of the casing, the leak collector having a trough that extends about the sidewall of the casing, the trough of the leak collector sized and positioned for receiving liquid flowing down the sidewall of the casing at the bottom portion of the casing,
wherein the RFID tag is positioned above the trough of the leak collector, and
wherein the wicking material extends between the trough of the leak collector and the RFID tag.
10. The filter assembly of claim 9 , wherein the exterior surface of the casing defines a diameter at the bottom portion of the casing, the trough of the leak collector also defining a diameter, the diameter of the trough being larger than the diameter of the exterior surface of the casing at the bottom portion of the casing.
11. The filter assembly of claim 9 , wherein the trough of the leak collector slopes towards the wicking material.
12. The filter assembly of claim 11 , wherein a highest point of the trough along a vertical direction is positioned opposite the wicking material about the casing.
13. The filter assembly of claim 9 , wherein the RFID tag is recessed within the casing at the exterior surface of the casing.
14. The filter assembly of claim 9 , wherein the casing and the leak collector are integrally formed with each other from a common material.
15. The filter assembly of claim 9 , wherein the leak collector is mounted to the casing via adhesive, spin welding or ultrasonic welding.
16. The filter assembly of claim 9 , wherein the leak collector has an installation assist fin that projects away from the bottom portion of the casing.
