CKV-3 is one of the most widely used activated carbon types. It is a coal-based, pelletised, steam-activated carbon with a nominal grain size of 3 mm. Due to the wide variety of pore sizes, it is an all-round activated carbon. The advantage of pelletised activated carbon is a lower pressure drop than granular activated carbon, due to the similarity in grain sizes in the filter bed.
Gases that can be removed include:
- Organic gases
- Volatile organic compounds (VOC),
- Chloride (Cl2)
This medium is also often mixed with CKO-Purple 8% to create a medium that can remove a very wide range of gases.
