Clack (A8014) Filter Ag 1 CF Bag

Filter AG is a granulated silicon dioxide sediment media of irregular surface characteristics. This cost effective media offers high filtration rate with small amount of the involved granulate. Filter Lite may be used several times thanks to backwash process. The media effectively stops regular water solid sediments and drastically reduces amount of the suspended matter.
