GC 4x8B

Granular Activated Carbon

GC 4x8B is a virgin activated carbon. Derived from the finest grades of low ash coal, it is granular in form. Its high activity and surface area makes it ideal for most vapor phase applications including general odor removal and the adsorption of organic contaminants from vapor streams.

Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable Local, State and Federal guidelines.
