Use original parts only when servicing the filter. 11. Arkal cannot accept responsibility for any changes or modifications to the equipment. Special Note Before opening the filter lock, check that there is no pressure in the filter. 3 .. 3. Description & Operation Disc Filtration Technology Arkal Filtration Systems uses a specially designed disc filtration technology.

5 Thin, color-coded polypropylene discs are diagonally grooved on both sides to a specific micron size. A series of these discs are then stacked and compressed on a specially designed spine. When stacked, the groove on top runs opposite to the groove below, creating a filtration element with a statistically significant series of valleys and traps for solids. The stack is enclosed in corrosion and pressure resistant housing. 'XULQJ WKH ILOWUDWLRQ SURFHVV WKH ILOWUDWLRQ GLVFV DUH WLJKWO\ FRPSUHVVHG WRJHWKHU E\ WKH VSULQJ V.

6 Power and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolation from the outer diameter to the inner diameter of the element. Depending on the micron rating, there are from 18 (in 400 micron discs) to 32 (in 20 micron discs) stopping points in each track, thus creating the unique in-depth filtration. Table of Filtration Grades of the Discs and Color Code 4 .. Spin Klin Technology Spin Klin Spine Model II. Spin Klin Spine - The Core of the Spin Klin Filtration System The Spin Klin discs are stacked on the Spin Klin spine.

7 The discs are color-coded according to micron size, and are assembled to suit your water filtration requirements. The spine assembly has a spring compression unit and an internal piston, which operate during alternate filtration or backwash modes. The spine assembly is specially designed to compress the micron IN. housing. 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.

8 OUT. Spin Klin Automatic Backwash Operation Activated by a predefined command (differential pressure or time) alternate units of the Spin Klin system go into backwash mode. The inlet valve is shut as the drain is automatically opened. During the backwash 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.
