CKV-4 is the second most widely used activated carbon in industrial applications. It is a coal-based, pelletised, steam-activated carbon with a nominal grain size of 4 mm. Due to the wide variety of pore sizes, it is an all-round activated carbon. The advantage of this 4 mm pelletised activated carbon is an even lower differential pressure than the CKV-3. The performance is slightly lower, however.

Gases that can be removed include:

  • Organic gases
  • Volatile organic compounds (VOC),
  • Hydrocarbons
  • Chloride (Cl2)

This medium can also be mixed with CKO-Purple 8% to create a medium that can remove a very wide range of gases.
