PRODUCT DATA BULLETIN
NUCHAR®WV-B
Nuchar WV-B is a low-density, high-activity, granular activated carbon with a high surface area and
unique pore size distribution. This high specific surface area and broad pore size distribution makes
Nuchar WV-B highly efficient for the purification of gases and vapors. This carbon is particularly efficient
in gasoline vapor recovery systems and air purification applications. It also can be utilized in liquid
applications such as decolorizing process liquids and other purification steps. It is available in 6x18,
10x25, 14x35, and 20x50 mesh sizes. Nuchar WV-B meets the food-grade quality of activated carbons
as
defined in the current edition of the Food Chemicals Codex.
