Activated Carbon Data

The activated carbon granules used in TOMCO2 Systems’ Model FS-77L and FS-90L filters are made from selected coconut shell to insure positive quality control during the manufacturing process. Virgin raw material is activated thermally in a rotary kiln steam atmosphere. By maintaining strict quality control standards, high adsorption of odors and other contaminates from the occupied air space can be achieved.
