Polyethersulfone Dual Layered Membrane Cartridge, 0.22 Micron Rating, DPS-20, General Grade

DPS general grade dual layered Polyethersulfone cartridges are custom configured to increase the surface area and give maximum throughputs for general purpose use wherever a cost effective membrane filter is required. DPS cartridges require fewer change outs and are configured for maximum solids holding at the rated pore size thus lowering the cost of filtration. DPS cartridges are flushed with 17+ megohm-cm water to remove potential extraneous manufacturing debris. These cartridge modules are also individually tested for integrity. Priced below special purpose cartridges, DPS cartridges are still manufactured with the same careful attention to both quality and performance.
