Cytiva, KA4J045P1, Pall™ HDC II membrane in Kleenpak™ capsule, 4.5 μm, KA4, 0.33 m² EFA, 38 mm sanitary flange

HDC II membrane in Kleenpak™ capsules deliver extraordinary contaminant-holding capacity, maximum flow rate, and low costs per liter of filtered fluid.
The HDC II filter medium is comprised of high-performance pleated cartridge with polypropylene filter medium that uses fibers of varying diameters to produce a pore size distribution from coarse (upstream) to fine (downstream). The fixed pore structure means that contaminants will not unload under variations in flow or pressure differential, and fibers will not migrate or become dislodged to contaminate process fluids.
HDC II media also has high efficiency in air and gas applications and HEPA filtration is possible utilizing the J012 grade.
