DPM-6980 Cartridge for Pentair Quad DE 80 | 80 Sq. Ft. | 178655 | C-6980

The DPM-6980 Cartridge is a precision replacement filtration element designed for use in the Pentair Quad DE 80 series (OEM part 178655 / C-6980). Each individual cartridge offers approximately 20 square feet of high-capacity pleated media and measures about 6-¼″ outer diameter by 26-¾″ length — the Quad DE 80 tank requires four cartridges to achieve full 80 sq ft of filtration-area. Crafted with a reinforced core and durable end-caps, this replacement cartridge withstands routine rinsing, pool chemical exposure, and supports optimized flow through the system’s manifold design. By swapping in the DPM-6980 when your cartridges are clogged or showing elevated pressure, you restore your Quad DE 80’s performance and maintain crystal-clear water with reduced maintenance.
