Arkal Spin Klin Jasper Units (Automatic Backwashing)

Manufacturer: Arkal

Arkal Spin Klin Jasper Disc Filters (Automatic Cleaning)

Arkal Disc Filters are washable pre-filters that will extend the life of the filters that follow it. If your water is visibly dirty then adding a disc filter as a first stage is highly recommended.

Disc Filtration Technology (Manufacturers Information: http://www.arkal-filters.com)

Arkal Water Filtration Systems operate using a specially designed disc filtration technology. Thin, colour-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.

During the filtration process, the filtration discs are tightly compressed together by the spring's power and the differential pressure, thus providing high filtration efficiency. Filtration occurs while water is percolating from the peripheral end to the core 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.

Benefits:

  • Removes large sediment from water

  • Easy to install

  • Easy to maintain

  •  No need for replacement cartridges

Keep in mind:

  • The disc filter does not filter the water finely enough for bacteria or heavy metals

  • The Jasper Units are built overseas as per order. As a result the lead time for a unit is 8 to 12 weeks. 

  • Larger versions of the Arkal Spin Klin Automatic cleaning disc filters are avaliable as well, please visit the contact us to enquire about larger options.

Specifications

50mm Jasper Disc Filter Head Unit
Pressure Maximum for water (m) 100
Flow rate Maximum (m3/h) for 130um to 400um 15
Flow rate Maximum (m3/h) for 100um 12
Flow Rate Minimum during backflush (m3/h) 10

Keep in mind that the above specifications are for a single japser head unit, each additional jasper head unit on a battery increases the maximum flow rate and filtration area. For example a double jasper battery has a maxmium flow rate of 30 (m3/h) at 130 microns.

How do the spin klin jasper units work?

The Arkal spin klin units work on pressure differential.

As the jasper unit runs dirt particles begin to build up on the filters surface. This build up starts to lower the pressure level on the outlet side of the disc filter. The pressure differential (PD) switch detects the difference in pressure between the inlet and the outlet of the disc filter, when the pressure on the outlet drops below a certain level the PD switch triggers the automatic back wash cycle.

In the case of the jasper units with multiple head units, the flush cycle cleans one head unit at a time which means the other heads continue to filter even during flushing.
