Replacement ceramic disk fits FG104LWC fogger w/remote and FGDR2 5 head fogger. Replace disk when fog is reduced or mixed with water droplets. Average life span of a disk is about 1 year if the fogger is used only several hours a day and if the disk is kept clean. Life span is reduced if calcium and algae buildup are not removed. This disk will fit any fogger/mister using the 20mm (approx 13/16") disk and includes replacement tool.
