Abstract

Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck forming a sealed cavity. A filter coupled to a surface of the base deck within the cavity filters particulate from a flow of gas in the cavity. The recirculation filter including a protrusion extending over a surface of a storage medium within the cavity that diverts gas from a surface of the storage medium toward the filter. A bypass channel, defined by a portion of the cavity and a portion of the filter, in conjunction with the protrusion forms a pressure differential that draws a first portion of the diverted gas through the filter by bypassing the filter with a second portion of the diverted gas.
