Authors Abstract
Content
The purpose of this study is to compare the dust loading behavior of ten filter media. The filters are used in engine air filtration, self-cleaning industrial air cleaners, building heating ventilation and cooling (HVAC), automotive cabin air filtration, air respirators, and general purpose air cleaning. Several types of filter media are tested. The filters include cellulose, synthetic (felt), glass, dual-layered glass/cellulose, mixed synthetic/glass, gradient packing glass, and electrically charged fibers. The initial pressure drops and fractional collection efficiencies as a function of particle size are reported. The filters were evaluated with two test dusts to investigate the size-dependent dust loading behavior. The two test dusts are SAE fine and submicron alumina powder (median diameter 0.25 μm). The results are analyzed and compared. It was found that the cellulose filters exhibited surface loading behavior and have the fastest growth of pressure drops. Other filters are found to have depth loading and more gradual increases in pressure drops.
