The high efficiency steel filters for nuclear air cleaning
We have, in cooperation with industry, developed high-efficiency filters made from sintered stainless-steel fibers for use in several air-cleaning applications in the nuclear industry. These filters were developed to overcome the failure modes in present high-efficiency particulate air (HEPA) filters. HEPA filters are made from glass paper and glue, and they may fail when they get hot or wet and when they are overpressured. In developing our steel filters, we first evaluated the commercially available stainless-steel filter media made from sintered powder and sintered filter. The sintered-fiber media performed much better than sintered-powder media, and the best media and the smallest fiber diameter. Using the best media, we than built prototype filters for venting compressed gases and evaluated them in our automated filter tester. 19 refs., 20 figs.
