GC 4x8D

Granular Activated Carbon

GC 4x8D is a virgin activated carbon. Derived from bituminous coal, it is granular in form. A general purpose carbon, it is appealing where low-pressure drop is needed.

GC 4x8S Pressure Drop Curve


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.
