2" Arkal Spin Klin™ Jasper Disc Filters (Self-Cleaning)
Arkal Disc Filters are washable pre-filters that will extend the life of the filters that follow them. If your water is visibly dirty then adding a disc filter as a first stage is highly recommended.
Arkal Water Filtration Systems operate using a specially designed disc filtration technology. 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 a corrosion and pressure resistant housing.
The 2" Spin Klin™ Disc Filters are self-cleaning and will automatically backwash the discs when they start to become blocked, removing the need for manual cleaning.
The Arkal 2" Spin Klin™ Jasper DIsc Filters are available with the following micron discs: 20 microns (grey), 55 microns (green), 100 microns (Black), 130 microns (red), and 200 microns (yellow).

How the 2" Spin Klin™ Jasper Disc Filters Works
General
The Arkal 2" Spin Klin™ Jasper DIsc filter is a polymeric, series of automatic disc filters with a patented self-cleaning backwash mechanism.
The Arkal 2" Spin Klin™ Jasper DIsc filter is for flow rates of up to 20 m3/h (88 GPM) with filtration degrees ranging from 20 – 200 micron. Inlet /Outlet - 50 mm (2”) diameter.
The Filtration Process
The discs are stacked on the Spin Klin™ spine and assembled according to pre-determined water filtration requirements. During filtration, the discs are compressed by means of a pre-loaded spring and differential pressure, forcing the water to pass through the grooved disc surface, thus trapping the solids.
The Backwash Process
Activated by a pre-determined time command or differential pressure, the filter enters backwash mode. The inlet valve port shuts as the drain valve port opens. Water flows through a bypass filter screen into the outlet valve and into the filter. During the backwash process, pressure is released and the spine’s piston elevates, releasing the compression on the discs. Tangential jets of filtered water are then forced through the nozzles positioned along the spine. At this stage the discs spin freely, loosening the trapped solids which are then flushed out.
