Description
Centaur NDS 12×40 is unique in that it concentrates reactants via absorption and then promotes their reaction on the surface of the pores. Centaur NDS 12×40 is a low water-soluble ash product ideally suited for devices requiring certifications under the rigid standards of ANSI/NSF. Centaur NDS 12×40 is component listed under NSF Standard 42.
