Spin Klin Technology - Spin Klin Spine
General:
The Spin Klin discs are stacked on the Spin Klin spine.
The discs are color-coded by micron size , and are assembled
according to your water filtration requirements. The spine
assembly has a spring compression unit and an internal piston
which are used to alternately compress and release the discs
during filtration and backwash cycles.
Filtration Mode:
During the filtration process the filter discs are tightly
compressed together by the spring and the differential
pressure, forcing the water to flow through the grooves and
traps of the discs .
Backwash Mode:
During backwash the discs are released by releasing the inlet
hydraulic pressure. Multi-jet nozzles provide tangential spray
on the loosened discs, causing them to spin, and release the
retained solids, which are flushed out to the drain.

Filtration Position:
Water flows from port A (main supply) to port B (filter connection). Port C (drain water outlet) is closed
by the seal.
Backwash Position:
Command pressure is applied to the top side of the diaphragm through port D. The diaphragm moves
down, pushing the sealed body by the shaft. Port A is closed by the seal, preventing flow to the filter.
Port C is now open allowing flushing water to flow from port B (filter connection) to the drain.
