Activated Carbon Filter Cartridges employ a specific sintered carbon technology that combines the best features of both powdered (PAC) and granular (GAC) activated carbon in one cartridge. These employ a spun bonded media as a pre-filtration layer and are accessible with molded polymer ends for superior sealing as well as boosted product performance. These proffer an extremely economical solution to several communal liquid treatment applications. The large carbon surface area displays outstanding chlorine reduction characteristics. The graded density pre-filtration layer insures effective sediment removal as well as protection of the carbon media. These Activated Carbon Filter Cartridges render excellent chemical compatibility as well as stability in aqueous solutions. The products have minimum carbon release when associated to conventional loose filled granular (GAC) style cartridges.
