An assembly comprises a housing and a rotatable data disc within the housing. The rotatable data disc creates a gas flow within the housing when the rotatable data disc rotates. The assembly further comprises a filter at a perimeter position of the rotatable data disc positioned to capture a portion of the gas flow, a first support element fixed relative to the housing and adjacent an upstream side of the filter, wherein the portion of the gas flow circumscribes the first support element and a second support element fixed to the housing and adjacent a downstream side of the filter, wherein the portion of the gas flow also circumscribes the second support element.
