Arkal™ Spin Klin Disc Filters - 10 bar

Arkal™ Spin Klin Disc Filters - 10 bar


Spin Klin® discs are stacked just like the manual disc filter but on a specially designed Spin Klin® spine. The spine assembly has a spring compression unit and an internal piston, which operate during alternate filtration or backflush modes. The spine assembly is specially designed to compress the filter element. 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.

Activated by a predefined command, the alternate units of the Spin Klin go into backflush mode. During the backflush process, the disc compression is released. The spine piston rises, releasing the pressure on the discs. Tangential jets of clean water are pumped at high pressure in the opposite direction through nozzles at the centre of the spine. The discs spin free and clear, loosening the trapped solids. Solids are quickly and efficiently flushed out through the drain.

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.

Product Features
  • Engineered for efficient operation with no maintenance
  • Flat, grooved, plastic rings stack together to form filter element.
  • Depth filtration - increasing filtration efficiency
  • Greater holding capacity as water is filtered through the entire ring depth, not just the surface
  • Constructed of the highest quality UV protected reinforce polymer plastic
  • Degree of filtration is easily changed by replacing the disc rings with the desired grade size
  • Available in a range of sizes, degrees of filtration and flow capacities
  • The Spin Klin® Jasper can be operated as stand-alone unit or combined to form modular filter batteries
  • The Spin Klin® Ruby is normally operated combined as modular filter batteries
  • Robust design
  • Pressure differential disc compression ‎
  • Captures and retains significant amount of solids ‎
  • Completely corrosion resistant ‎
  • Diverse filtration grades: 20µm to 400µm
