A close-up view of the passageways being formed is illustrated. The violet "walls" are two adjacent curves of the continuous sinuous rib ("labyrinth rib") and the red "beams" are segments of the annular ribs. The white "windows" are the passageways openings.
The Super Disk structure is based on a unique pattern that form micro passageways for the water flow: a close up picture of the unique ribs on the Super Disk face is shown below.
The dirt is trapped in the ribs, as shown in the picture below: the smooth plastic face enables easy wash of the disks, thus the filter recovers to its initial performance. All SDF self-clean products are recovered under a quick and water saving back-flush.
