Unicel 145 Sq Ft Filter Cartridge Set for Jandy CL580, C-7482-4

The Unicel C-7482-4 is a set of four replacement filter cartridges for the Jandy CL580, giving 145 square feet of filtration in total. Each cartridge measures 7 inches in diameter and 33 inches long, with open ends top and bottom.

Cross references

This set replaces the Jandy OEM cartridges under part number A0104100. If you have been quoted a Pleatco PJAN145 or a Filbur FC-0820, those are the same element from other manufacturers. The single cartridge number is C-7482, and the trailing 4 in C-7482-4 marks it as the four cartridge set.

Change all four

The four cartridges work as one filter area, so replacing one and leaving three tired ones in place gets you very little. When clean pressure no longer drops back to where it read on a new set, or when pleats are torn, stiff or permanently gray, change the whole set together and start the pressure record over.
