Activated Carbon Can-Filters CKV-3 CKV-4 pellets, 8kg

8 kg bucket of pelletised charcoal for replacement filters.

The Base material of the Pelletized Carbon is coal. By heating up the base material pores and canals occur. This process is called the activation process. Hence Active Carbon. This can be done Chemically or Thermally. With Chemical activation we add phosphoric acid and/or zinc Chloride during the heating process. Thermic activation means we add dry steam on a high temperature to the carbon. The semi-finished product as a result is very porous and has mostly small to very small pores.
