FilterStar – The Innovative Filtration System for Greater Cost-Efficiency.

FilterStar is a two-stage fine filtration system for dampening solution and is housed in a cabinet. Thanks to this system, dampening solution lasts three to six times longer before having to be replaced. FilterStar pumps the soiled dampening solution from the main tank of the CombiStar or HydroStar into the pre-filters, where coarse impurities are removed. The main filter next separates extremely fine dirt particles as small as 1 μm. The cleaned dampening solution is then pumped back to the CombiStar or HydroStar.
This process makes the dampening solution last far longer, which reduces the frequency of costly dampening solution changes and ultimately makes the press more costefficient. The Prinect Press Center displays the level of pre-filter and main filter soiling for the FilterStar. Because the filtration system operates in the bypass, it is also possible to cut makeready times significantly by replacing filters on the fly.

The FilterStar Compact entry-level system is a dampening solution filtration system housed in a compact console. Filtration takes place in a single stage in a granulate cartridge. The soiled solution is pressed through a 30 cm (11.81 inches) layer of quartz granulate. The cleaned dampening solution is then returned to the main tank. The FilterStar Compact filters the dampening solution in the bypass.
This means the filter cartridge can be replaced at any time on the fly.

FilterStar/FilterStar Compact  at a glance:

• Increases the dampening solution's service life from 2-3 to 6-12 months
• Stabilizes the ink/water balance
• Reduces the frequency of costly dampening solution changes
• Ensures consistently high print quality irrespective of the dampening solution's age or condition
• Improves the printing process, for example when switching frequently between UV and conventional inks
• Reduces dirt build-up in the pipes
• Reduces soiling of the water pan, intermediate tank, and main tank
