A known filtration technique for a disk file of the sealed enclosure type relies on the pumping action caused by the rotation of the disks and integral fan blades to produce airflow through a filter located within the enclosure. To increase the flow of air through the filter, the pressure differential across it is increased in two ways. Firstly, the filter is provided with vanes to deflect pumped air into inlets on its high pressure side. Secondly, a baffle restricts the flow of pumped air past outlets on the low pressure side of the filter.
