FILTER DEVICE.

摘要

A filter device (10) filters contaminants from air for magnetic disk drive systems. The filter has layers of permeable fabric material allowing flow through the filter. An adsorptive slurry (18) is deposited in a discreet pattern onto one layer (16) with a cover layer mounted over the adsorptive deposit. The slurry retains a high adsorptive material surface area for improved adsorption of contaminants. The slurry is placed onto the base material using a screening or other similar application method.
