Spin Klin Technology
Spin Klin Spine - The Core of the Spin Klin Filtration System
®
The Spin Klin discs are stacked on the Spin Klin
color-coded according to micron size, and
your water filtration requirements. The spine assembly has a spring
compression unit and an internal piston, which operate during alternate
filtration or back-flush modes. Inside the housing a spring and the
pressure difference compress the discs tightly during the filtration
process, forcing the water to flow between the grooves and trap the solids.
Spin Klin Automatic Back-flush Operation
Activated by an external command (differential pressure or time)
alternate units of the Spin Klin
Three-way valve closes the inlet to the filter pod and opens the
drain. During the back-flush process, the compression spring is
released and the pressure difference is eliminated. The spine piston rises
up, releasing the pressure on the discs. Tangential jets of clean water are
pumped at high pressure in the opposite direction through nozzles at the
center of the spine. The discs spin free and clear, loosening the
trapped solids. Solids are quickly and efficiently flushed out through
the drain.
