Filter housings designed to house activated carbon granular media . Typical uses are in water/waste water treatment and in amine sweetening systems. Pre and post bed filtration required in most cases to prevent "fouling" of the activated carbon bed and to prevent carbon particles from migrating downstream. Pressure ratings to 5000 PSI, ASME code stamp, CRN and NACE compliance available. Numerous closure options and custom designs. Materials of construction include carbon steel, 304 & 316 SS and various alloys such as Alloy 20 & Hastelloy C-276.
