Sursorb A is an impregnated granular activated carbon. It is designed for removing organic gases and vapours and solvents with a boiling point above 65 degrees. It traps vapour molecules with higher vapour pressure. It has a longer operational range and excellent temperature stability.  Its base material is manufactured by activating steam at high temperatures on coconut shell charcoal. It complies with the EN14387 standard for industrial gas mask filters.
