Aerosol filtration with steel fiber filters

摘要

We have conducted an experimental study of aerosol penetration through a new high efficiency steel fiber filter and filter media that we developed in cooperation with Pall Corporation. Our previous studies have shown that sintered steel fiber media have significant improvements in higher filter efficiency and lower pressure drop than the previous steel filter technology based on sintered powder metal media. In the present study, we have measured the penetration of dioctyl sebacate (DOS) aerosols through flat sheet samples, pleated cartridge filters and a 1000 cfm filter having 64 cartridges housed in a 2 (times) 2 (times) 1 ft. frame. The steel fiber media used in our study consists of 2 (mu)m diameter stainless steel (316L) fibers sintered together into sheets.
